Prospects For Bio-Fortification Reducing Micronutrient Deficiency In Kenya: Lessons From Sugar Fortification Programmes

Date & Time: From 2014-06-17
To 2014-06-20
Description of Conference

Conference Paper

Abstract
Food fortification has proven to be an important strategy for addressing micronutrient deficiency that includes vitamin A, iron and zinc deficiency in most developing countries. Development efforts have thus focused on breeding for crops that have natural ability to produce through a process widely known as bio-fortification. However, efforts to promote mass fortification of foods (both bio and industrial) have yielded little success due to existence of weak information on factors affecting consumption of these nutritionally-enhanced foods. This study therefore, assessed factors affecting consumption of fortified foods using Vitamin A fortified sugar as a case study. Data collected from rural and urban areas of Kenya was analyzed through a probit model to examine consumption drivers. The results showed that point of purchase, trust for stakeholders’ involved in fortification, consumer’ awareness and knowledge of the importance of vitamin A have significant effects on consumption of fortified foods. These findings offer useful insights for the development of nutrition policies in Kenya, and Africa at large.
Keywords: Micronutrient deficiency, bio-fortification, consumption drivers, probit models

Consumer awareness of food fortification in Kenya: The case of vitamin-A-fortified sugar

Date & Time: From 2014-06-16

Description of Conference

Conference Paper

Abstract
Food fortification is considered as an important strategy to address micronutrient malnutrition, which is a key challenge in most developing countries. In Kenya, the National Food Security and Nutrition Policy focus on pilot efforts on food fortification. However, lack of empirical information on consumers’ awareness for fortified foods remains the barrier to the uptake of these enriched foods. This study assessed the consumers’ awareness and analyzed factors affecting levels of awareness for fortified sugar. Awareness was assessed using descriptive statistics while
binary logit model was specified to analyze factors affecting the levels of awareness. The study used primary data from a random sample of 350 consumers in Nairobi County (a completely urban setup), and Kakamega County (a relatively rural setup). The study found that about 55% of the households were aware of fortified sugar and that awareness levels were statistically higher for urban consumers. However, only 26% of the respondents were aware of the importance of vitamin- A in their diets. Results from binary logit regression showed that age of consumers, purchasing from supermarket, reading newspaper, dwelling place (urban or rural) as well as having a child below the age of five years, were the significant factors influencing consumers’ awareness of fortified sugar. These findings offer useful insights for the development of preference-based sugar fortification programmes in Kenya. Moreover, the results would guide formulation of policies against micronutrient malnutrition in Kenya and other developing countries, with similar conditions.
Key words: Fortification, vitamin-A, consumer awareness, binary logit

ANAEMIA STATUS OF INFANTS 4-6 MONTHS OLD IN A RESOURCE-CONSTRAINED SETTING

Date & Time: From 2013-08-30
To 2013-10-01
Description of Conference
 
 
(Njenga J.N., Mwangi A.M., and Kogi-Makau W.) 
 
 
Abstract (submitted and accepted to: IUNS 20th International Congress of Nutrition to be held in Granada, Spain in September 2013).
 
Background:  It’s often assumed that healthy full-term infants are endowed with adequate iron stores and haemoglobin that provides recyclable iron. It’s speculated that many infants <6 months in less-developed countries are iron-deficient. Yet, WHO/UNICEF recommends exclusive breastfeeding for the first 6 months while use of fortified complementary foods/vitamins-mineral supplements is only recommended after 6 months in breastfed children (PAHO/WHO, 2004). Iron supplementation in iron-deficient Honduran infants (4-6 months) showed an increase in haemoglobin (Domellof et al (2001). There is need to re-think the current supplementation programs targeting infants >6 months.
 
Objective: To determine anaemia status among infants aged 4-6 months prior to a supplementation study.
 
Methods: Setting:  Kenyan South Coast (INSTAPA Project). Haemoglobin (Hb) was measured in 219 infants (4.5-6 months old) using venipuncture blood samples (HemoCue Hb 301 System). Infants’ anaemia status was defined as Hb concentration ≤110g/L (race-adjusted). Anaemia status was further categorised as severe (Hb <70g/L), moderate (≥70 - <90g/L), and mild (90 - ≤110g/L), respectively.
 
Results: Mean age was 5.64 months (SD 0.211). 79% of infants (n=173) were anaemic. Overall, 82% (n=143) and 16% (n=29) had mild and moderate anaemia, respectively.
 
Discussion: WHO/UNICEF recommendation on exclusive breastfeeding assumes that iron stores are adequate for the first 6 months. These findings concur with Domellof et al (2001) that showed Honduran infants <6 months were iron-deficient.
 
Conclusion: With 1:4 infants being anaemic, the data strongly suggests a re-look at the iron status of children <6 months, so as to adjust existing guidelines on exclusive breastfeeding for the first six months. The high level of anaemia begs the question whether caregivers are receiving correct contextual advice.

Abstract (Trends and opportunities in the production, processing and consumption of staple food crops in Kenya held on 25-26 April 2013 at Intercontinental hotel, Nairobi, Kenya.)

Potato crisps are popular snacks consumed worldwide. Manufacture of crisps in Kenya is dominated by small scale processors and there exist, depending on the market niche, a variety of flavors such as salted, tomato, chilli and cheese flavored . This study was designed to investigate the influence of carrot powder as a flavoring agent on β-carotene, ascorbic acid and sensory properties of potato crisps from three Kenyan potato varieties. Potato crisps from each variety were flavored by applying carrot powder at the rates of 0%, 2.5% and 5% of crisps weight. Total carotenoids varied in raw tubers from 115.38 to 190.67 µg/100g dry weight in Tigoni and Dutch Robjin, respectively. Total carotenoid content significantly (P<0.05) increased  on  addition of carrot powder to crisps reaching highest levels of 921.42, 1220.49 and 1269.01 µg/100g of dry weight, respectively. The levels of β-carotene were noticeably low in raw tubers and fried crisps, being undetected in Tigoni while it varied from Dutch Robjin (0.06, 0.21 µg/100g) to Cangi (0.11, 0.26 µg/100g). β-carotene and reduced ascorbic acid (RAA) significantly (P<0.05) increased with addition of carrot powder in all the varieties. Flavoring using carrot powder significantly (P<0.05) reduced sensory scores on flavor, color, oiliness and overall acceptability.  Crisps flavored at the rate of 0.25% were acceptable irrespective of the variety. On the other hand, all crisps flavored at 0.5% were unacceptable to panelists. Carrot powder can therefore be used as a flavoring agent to provide a natural source of vitamin A to consumers.

Key words: carrot powder, carotenoid, potato crisps, flavors, color.

Abstract (Trends and opportunities in the production, processing and consumption of staple food crops in Kenya held on 25-26 April 2013 at Intercontinental hotel, Nairobi, Kenya.)

Potato plays a major economic role in the world and has been considered a major staple in developing countries such as Kenya where it ranks second to maize in terms of utilization. The importance of potato in Kenya is anchored on its role in alleviating poverty and fighting hunger as well as income generation thereby playing a dual role as food and cash crop. The crop is traded both in fresh and processed forms and the value chain is a source of sustainable livelihoods. Potatoes are grown by over 800,000 farmers on 160,000 ha and are valued at KE 46 billion per annum at the consumer level. Most of the varieties grown are locally adapted and are used for domestic consumption and processing.

The Kenyan potato value chain indirectly employs 2.5 million people including researchers, extension agents, seed inspectors, transporters, market agents, processors among others. They are, however faced with a number of challenges. Although the legal limit for ware potato bags is 110 kg, middle men use extended bags often over 150 kg to fleece the farmers. Due to lack of storage facilities, farmers often sell at low prices at harvest while consumers pay high prices 2-3 months later due to low supply of potatoes before the next harvest. Potato is now being considered by the Ministry of Agriculture as a possible alternative crop to maize which is having problems with incurable diseases from unknown sources.  Many farmers in maize growing areas are now adopting potatoes for food and income security reasons. Majority of the households in potato growing zones and a number of urban dwellers use the tubers as important accompaniment to diverse dishes. On the other hand, potato crisps and French fries (chips) are important processed products that form greater parts of menus in restaurants and hotels in major urban centers with crisps assuming large share in the supermarkets, kiosks and roadside shops. There exist a great potential in the potato value chain as much as there are challenges and opportunities. This paper is a step-by-step diagnosis of the potato value chain in Kenya, from production, post-harvest handling, processing and marketing including challenges and opportunities.

Trends and Opportunities in the Production, processing
and Consumption of Staple Food Crops in Kenya.

Conference Venue: Intercontinental Hotel, Nairobi, Kenya

Conference Sponsors: KIRDI and Max Rubner Institute (MRI) of Germany

Author: Prof. Jasper K. Imungi

Abstract:

The potential of nixtamalization of maize to improve safety of consumption, nutritional value and processing property. Abstraction of the presentation: Nixtamalization or alkali cooking of maize helps to reduce the levels of aflatoxin and especially if the cooking is coupled with decortication. This has the function of reducing aflatoxin exposure in individuals who subsist mainly on maize and maize products like the Kenyans. Nixtamalization also helps to release niacin from the bound form in maize - niacinogen -, also alters the property of proteins and starch so that they are more digestible, and finally releases minerals that are bound to sequestering agents such as phytates.  The protein functionality is also transformed so that it acquires some properties similar to those of the wheat gluten in the formation of dough. Use of maize in the manufacture of gluten free breads, both oven and unleavened, will diversify the forms in which maize is utilized.

4th International Maize Nixtamalization Congress

Conference venue: Queretaro City Mexico

Author: Prof. Jasper K. Imungi

Abstract:

Kenyans are perennially afflicted by aflatoxicoses and chronic aflatoxin exposure. Nixtamalization of maize and maize products has the potential to reduce the levels of aflatoxin in maize in the decorticated maize through physical removal and in whole maize products through chemical degradation. Nixtamalization also has the potential to increase nutrition of maize through releasure of niacin from niacinogen and improve digestibility of protein and starch, as well as the absorption of maize. Alkali cooked maize products should not be a problem in the country, because some communities are already engaged in the practice of cooking the products using the method. Finally the introduction of nixtamalized maize products such as tortillas will help to diversify utilization of maize.

Levels of Acrylamide in Commercial Potato Crisps Sold in Nairobi, Kenya.

Date & Time: From 2012-09-26

Description of Conference
 
Authors: Jackline A. Ogolla, George O. Abong’, Michael W. Okoth, Jasper K. Imungi, Jackson N. Kabira and Paul N. Karanja. (2012). 
 
Abstract (The seventh Egerton University International Conference: Research and Expo held on 26-28 September 2012 at Egerton University.)
 
Acrylamide has been found to be genotoxic and a neurotoxicant and its classification as a suspected human carcinogen calls for a concerted effort to minimize its presence in human diet. It is mainly formed in fried and baked carbohydrate rich foodstuffs such as potato chips and crisps through maillard reaction at elevated temperatures. This study was designed to determine the levels of acrylamide in commercial potato crisps that are sold in Nairobi, Kenya. Different brands of   potato crisps were purchased from retail outlets while unbranded (street) samples were purchased from kiosks in   five districts of the Nairobi County. The samples purchased were a total of 35 branded samples and fifteen unbranded samples. The parameters analysed were moisture, colour and acrylamide content. The moisture content of the crisps ranged from 0.39% to 7.97%. There was a significant (P≤0.05) difference among the crisps samples in color parameters. Out of the forty three products, most of the samples were light colored with lightness (L*) parameters greater than 50 apart from only two samples. Most samples tended towards green as shown by the negative values of redness parameter (a*) indicating that there was less or no excess browning of the products during frying. All the samples tended towards yellow as indicated by positive values of yellowness parameter (b*). 
Acrylamide levels significantly (P≤0.05) differed between the traded crisps brands ranging from non-detectable levels to 8666 μg kg−1 in the branded samples while in the unbranded samples it ranged from 5666 μg kg−1 in Kiosk 7 to 9499 μg kg−1 in Kiosk 6. There was a significant differences (P<0.05) in acrylamide levels between the branded and the unbranded (street) potatocrisps. Most of the flavoured brands were non-detectable. It therefore indicates that depending on the brand of crisps and amounts consumed by an individual, levels of acrylamide intake and exposure in Nairobi will differ greatly.

The samples purchased were a total of 35 branded samples and fifteen unbranded samples. The parameters analysed were moisture, colour and acrylamide content. The moisture content of the crisps ranged from 0.39% to 7.97%. There was a significant (P≤0.05) difference among the crisps samples in color parameters. Out of the forty three products, most of the samples were light colored with lightness (L*) parameters greater than 50 apart from only two samples. Most samples tended towards green as shown by the negative values of redness parameter (a*) indicating that there was less or no excess browning of the products during frying. All the samples tended towards yellow as indicated by positive values of yellowness parameter (b*).

Acrylamide levels significantly (P≤0.05) differed between the traded crisps brands ranging from non-detectable levels to 8666 μg kg−1 in the branded samples while in the unbranded samples it ranged from 5666 μg kg−1 in Kiosk 7 to 9499 μg kg−1 in Kiosk 6. There was a significant differences (P<0.05) in acrylamide levels between the branded and the unbranded (street) potatocrisps. Most of the flavoured brands were non-detectable. It therefore indicates that depending on the brand of crisps and amounts consumed by an individual, levels of acrylamide intake and exposure in Nairobi will differ greatly.

Key words: Acrylamide, potato crisps, carcinogen, processing.

1ST STUDENT- LED CONFERENCE HELD AT CAVS

Date & Time: From 2013-05-29
To 2013-05-30
Description of Conference

The University of Nairobi (UoN)- Center for Sustainable Dryland Ecosystems & Societies (CSDES) opened its doors to the first ever student-led conference whose motto was preparing the next generation for dryland sustainability. The conference was held from 29th-30th May, 2013 at the College of Agriculture and Veterinary Sciences (CAVS), Upper Kabete.

The two day conference on Transformative Education, Research and Engagement for Dryland Resilience and sustainability organized by the University of Nairobi (UoN) Students and Colorado State University (CSU), brought together students and leaders from various diverse sectors.

Prof. Isaac M. Mbeche, Deputy Vice-Chancellor in charge of student affairs opened the conference on behalf of the Vice –Chancellor.  The DVC was optimistic that the discussion of research findings and research ideas shared in the conference would contribute to renewed thinking on how to release the potential of drylands.

Dr. David Nkedienye, Governor Kajiado County, gave a keynote address on empowering the underrepresented groups for sustainability on dryland ecosystem & societies. He emphasized on the critical role of higher education if the counties have to take off. “There is need to bring expertise with good work ethics, the right attitude and effort into place. Young people and students need to come on board so as to achieve the right result”. Dr. Nkedienye said.

Student interns who had gone for field work in the drylands like Narok, Garissa, Isiolo, Samburu and Kajiado narrated their experience in the fields. One common problem was lack of infrastructure and networks in place. There was also the problem of language barrier.

The students emphasized on the need to evaluate relationship between human and wildlife and to strategize opportunities like wildlife farming and eco-tourism potential that will lead to sustainable wildlife utilization.  The need to train livestock herders on herd management also came up. It was evident that people living in the dryland still faced mobility hardships, insecurity and illiteracy.

While giving her closing remarks, Prof. Agnes Mwang’ombe, Principal, CAVS acknowledged the efforts of the students and all the participants in organizing and making the 1st student conference a success. She called on all the stakeholders to make the conference an annual event. “I challenge the CSDES and other stakeholders within the University to facilitate the student conference to become an annual event just like it is at Colorado State University. It is my hope that the conference presentations will be published in proceedings that can be one of the many to follow so that the outcomes of the conference will be widely disseminated.” She concluded.

IS REDD+ A GOOD POLICY OPTION FOR KENYA?

Date & Time: From 2012-07-13
To 2012-07-13
Description of Conference

The Centre for Sustainable Dryland Ecosystems and Societies (CSDES) held a very successful seminar on 13th July 2012 aimed at discussing the viability of adopting REDD+ as a conservation measure in the country. REDD+ stands for Reduced Emissions from Deforestation and Forest Degradation in developing countries. The Seminar was held in the Seminar room at the Department of Clinical Studies, College of Agriculture, University of Nairobi.

The Seminar, dubbed: Is REDD+ a good policy option for Kenya? attracted more than 40 participants from various institutions including professors and postgraduate students (both MSc. and PhD)  from the University of Nairobi (UoN),  Kenyatta University and Jomo Kenyatta University of Agriculture and Technology. There were also scientists from the National Museums of Kenya and some local non-governmental organizations. 

 “YES!” was the resounding answer given by an eminent scholar, Prof. Shellemiah Keya in response to the seminar question. He however noted that it must be applied within context and address real needs affecting local people. He was giving his remarks during a question and answer session after the presentation that was given by Dr. Sophie Chapman from the University of Cambridge and Dr. Rowena Maguire from Queensland University of Technology, Brisbane, Australia. The two scholars were sharing their experiences on global policy aspects of REDD+, highlighting key questions that need to be addressed before REDD+ can take off in Kenya.

The seminar was opened by Prof. Jesse T. Njoka who is the Coordinator of CSDES. The don welcomed the participants and presenters to the seminar, the first in a series that will run monthly touching on various dryland issues. His sentiments were echoed by the Chairman of the Department of Land Resources Management and Agriculture Technology (LARMAT), Prof. Robinson N. Kinuthia, who emphasised the need to share information and knowledge as a central mission of the university.

The presentations covered a wide scope of issues relating to REDD+, ranging from basic definitions to contemporary policy questions that tend to be sticky especially in the Conference of Parties to the United Nations Framework Convention on Climate Change. These include land use, emission (carbon) credits, links between REDD+ and livelihoods, and the importance of national actions. They highlighted key questions concerning REDD+ influences on land use by property law (such as land tenure), economic schemes and politics, and how institutions and national systems can seek to influence local level land use policy and legislation.

The five activities that they identified to define REDD+ include:

  1. Reducing emissions from deforestation
  2. Reducing emissions from forest degradation
  3. Forest conservation
  4. Sustainable management of forests, and
  5. Enhancement of forest carbon stocks

In their closing remarks, the presenters wondered aloud what local realities prevail that could influence REDD+ policy in the country. They noted that the context of application must directly address deforestation drivers and must involve primary stakeholders. The presenters were encouraged to partner with the College (CAVS) to seek entry points for education and research on the issue. Mr. Sam Mwangi, a PhD student in the Department of LARMAT,is doing his research in this area and seeks to explore some of these aspects.

Other issues that arose during the seminar were:

  • The need for the policy to address cultural practices such as land inheritance, a key reason for continuous land fragmentation;
  • The key question of indigenous forests under communal land ownership, which may not be addressed in the classic REDD+ model and can only be useful for demonstration purposes, attracting minimal investment;
  • The utilization of financial opportunities offered by REDD+ for rehabilitation of severely degraded forest patches in Northern Kenya, especially lands under use by refugee communities such as Dadaab; and
  • The need to develop lessons for scaling up REDD+ schemes.
