Abstract: Fish protein and calcium concentrate are one of the innovations of protein and calcium form development applied to low protein and calcium food. The chacunda gizzard shad, silver rasbora, and Bali lemuru were selected in fish protein and calcium concentrate production because these fish have many spines and their utilization has not been optimal yet. This study aims to know the protein and calcium protein concentrate profile of Anodontostoma chacunda, Rasbora argyrotaenia, and Sardinella lemuru. It used Complete Randomized Design with 3 treatments and 3 replications, A (A. chacunda), B (R. argyrotaenia), and C (S. lemuru). Results showed that FPC and FCPC of A. chacunda had a 19.6% yield, calcium 22.86 mg g-1, 58.97% protein, 14.38% fat, 5.67% water, 15.87% ash, and 5.12% carbohydrate. The protein concentrate of R. argyrotaenia had a 21% yield, calcium of 30.58 mg g-1, 58.13% protein, 20.08% fat, 5.65% water, 11.64% ash, and 4.49% carbohydrate. The protein concentrate of S. lemuru had a 16.6% yield, calcium of 24.65 mg g-1, 71.32% protein, 6.39% fat, 5.70% water, 12.08% ash, and 4.51% carbohydrate. The hedonic test indicated that the panelists preferred the protein concentrate of S. lemuru over the other two fish protein based on appearance, aroma, and texture.

Abstract: This study systematically evaluated the implementation of fortification practices, including quality assurance and quality control, among small-scale processors to ensure regulatory compliance. A descriptive cross-sectional survey was conducted in Ubungo district (Dar es Salaam) and Morogoro municipality, Tanzania, involving 38 processors. Data collection relied on observational checklists and IBM SPSS ® version 20 for analysis. Descriptive statistics revealed critical insights. Cleanliness and sanitation standards were met in only 36.8% of warehouses and 42.1% of production areas, underscoring hygiene deficiencies. Alarmingly, 26.3% of micronutrient premixes were inappropriately stored near heat-generating milling machines. Written procedures for quality assurance and quality control were virtually absent, with just 2.6% of processors having such documentation. A mere 13.2% of processors conducted quality checks on fortified maize flour to confirm micronutrient presence. This study identified pervasive shortcomings in quality control and assurance practices among small-scale processors. Hindrances included inadequate training in fortification standards, limited processing capacity, and constrained access to quality control facilities. Strengthening these practices is imperative to ensure the consistent delivery of safe, high-quality fortified maize flour, essential for the nutritional well-being of target populations. This action holds significant public health and food safety implications.

Abstract: Vitamin A Deficiency (VAD) is a public health problem in developing countries in children below five years. Orange Fleshed Sweet Potatoes (OFSP) are rich in β-carotene a pre-cassor for vitamin A. Being a cheap and affordable source, can be utilized by incorporating in staple foods to combat VAD in developing countries. OFSP fresh roots (Ejumla, Jewel and Carrot dar) were collected from Ukerewe and Misungwi District, Mwanza region for quality evaluation. The findings of the study indicated that there was considerable variance in the nutrient content across the several types of OFSP that were tested. Among the varieties that were chosen for analysis, it was found that Jewel had the maximum quantity of β-carotene (113,565 ± 1.45 µg/100 g), whilst Carrot dar had the lowest concentration (5,165 ± 3.38 µg/100 g). In addition to β-carotene, the aforementioned varieties of OFSP exhibited a diverse array of nutrients, including protein (3.82% - 8.86%), fat (0.32% - 0.51%), fibre (1.83% - 3.15%), carbohydrate (87.05% - 92.60%), ash (0.86% - 1.09%), ascorbic acid (15.04 mg/100 g - 17.27 mg/100 g), and energy content (385.19 Kcal/100 g - 392.92 Kcal/100 g). Several minerals were discovered in the selected OFSP varieties. Jewel exhibits a high content of essential minerals such as calcium (44.30 mg/100g), iron (1.34 mg/100g), zinc (0.35 mg/100g), and potassium (317.12 mg/100g). Conversely, Ejumla is characterized by its notable sodium (112 mg/100g) and magnesium (2.73 mg/100g) content, making it a valuable source of these minerals. Based on the findings, it can be concluded that OFSP possesses a high concentration of essential nutrients that play a crucial role in addressing both macro and micro-nutrient deficiencies in developing countries. Hence, individuals should integrate Orange Fleshed Sweet Potatoes into their primary food sources as a means of enhancing the overall nutritional value.
