Abstract: This study investigates the development of value-added food products from shrimp (Metapenaeus monoceros) waste (SW) with the aim of enhancing nutritional value, sensory quality, and sustainability. Shrimp waste was sun-dried and ground into shrimp waste powder (SWP), which was incorporated into four products: chips, soup powder, samosa wrapper, and wonton wrapper. Chips were prepared by combining sago powder and SWP with water, followed by cooking, drying, and frying. Soup powder was produced by mixing SWP with flour and selected ingredients, while samosa and wonton wrappers were prepared using SWP, flour, water, and salt. Proximate composition was determined using standard analytical methods: protein by the Dumas method, fat by rapid fat extraction, moisture by a Shimadzu moisture analyzer, ash by muffle furnace, and carbohydrate by difference. On a dry basis, SWP chips contained 8.75% protein, 0.50% fat, 67.75% carbohydrate, 10.18% moisture, and 12.85% ash. SWP soup powder showed higher protein content (19.50%) with 0.67% fat, 66.22% carbohydrate, 8.84% moisture, and 4.77% ash. Both SWP samosa and wonton wrappers contained 14.84% protein, 0.90% fat, 57.49% carbohydrate, 10.45% moisture, and 16.32% ash. Sensory assessment by 70 panelists indicated excellent acceptability, highlighting superior crunchiness and flavor in chips, desirable flavor in soup, and high-quality attributes in samosa and wonton wrappers. Microbial analysis revealed safe microbial loads, with shelf lives of approximately six months for chips, four months for soup powder at ambient conditions, and 45 days for wrappers at −40°C. Production costs were lower than commercially available alternatives. Overall, this study demonstrates the potential of shrimp waste valorization for sustainable food innovation and improved waste management.

Abstract: The prevalence of exclusive breastfeeding (EBF) stands at 41% globally, 43% in Africa, 61% in Kenya. The World Health Organization recommends EBF for six months. About half (49.2%) of Kenyan women are in the work force. These women are entitled to a three-month maternity leave under the Kenyan Constitution. They therefore do not have the privilege of being with their children all day to breastfeed and may require additional support to be able to breastfeed exclusively for 6 months. The purpose of this study was to determine the effect that counselling on expressed breast milk has on the duration of EBF among working mothers in Kiambu County. A cluster-based randomized controlled trial was adopted. The mothers in the intervention group received counselling on the benefits of EBF, breastmilk expression methods, benefits of expressing, storage, and feeding of expressed breastmilk. A researcher administered semi-structured questionnaire was administered to collect baseline data on socio-demographic factors among working mothers. Follow-up questionnaires were administered to both groups to collect information on breastfeeding practices. The data was analyzed using the Statistical Package for the Social Sciences (SPSS). Chi-square tests, odds ratios, and regression analyses were used to determine associations between variables. The prevalence of EBF was 70.4%. Significantly, the prevalence of EBF in the intervention group (86.1%) was higher than in the control group (54.9%). Mothers who received counselling (intervention) were five times more likely to practice EBF than mothers who did not receive counselling ([OR]: 5.105; CI 2.570-10.137; p<0.001). This contributed to the higher rates in EBF in the intervention group. This study established that counselling of working mothers on the use of expressed breastmilk could result in increased rates of EBF in Kiambu County. Therefore, working mothers need to be educated on optimal breastfeeding practices so that the rates of exclusive breastfeeding can improve.
