The Effect of NaOH Concentration on The Physical and Chemical Properties of Jerbung Shrimp (Fenneropenaeus Merguiensis de Man) Waste Powder

2024-04-30T11:17:46+07:00

This research was conducted to determine the effect of NaOH concentration on the physical and chemical properties of shrimp waste powder. This research used a Completely Randomized Design (CRD) with NaOH concentration treatment consisting of 5 levels (1%, 1.25%, 1.5%, 1.75% and 2%) and 4 repitition. The data obtained were analyzed statistically using analysis of variance and followed by Duncan's New Multiple Range Test (DnMRT) when necessary. The research shows that the NaOH concentration has a significant effect on the ash content, protein content, L* and b* values, but has no significant effect on the water content, fat content, solubility and a* values. The best characteristics of shrimp waste powder is obtained using NaOH 1.5% which produces powder with 4.22% water, 39.27% ash, 18.37% protein, 12.43% fat, solubility of 4. 04%, L* value 48.37, a* value 10.92 and b* value 21.47.

The Hyperglycemic Effect of Different Particle Sizes of Composite Flour from Maize, Wheat and African Breadfruit on Adult Diabetic Albino Rats

This study was carried out to determine the hyperglycemic effect of diets prepared with different particle sizes of composite flour from Maize (Zea mays), Wheat (Triticum aestivum) and African breadfruit (Treculia africana) on adult diabetic albino rats (Rattus norvegcus). The samples were milled into different particle flour sizes and used to prepare three different sets of diets (diet A, diet B, and diet C). Diet A represents the fine particle size composite flour, diet B represents medium particle size composite flour, while diet C represents coarse particle size composite flour. The broiler finisher, which serves as the control represents diet D. Sixteen rats were used in this experiment and separated into four groups of four rats each (three experimental groups and one control group). The experimental groups were injected with alloxan to induce diabetes, while the control group was injected with saline solution. Groups 1, 2, 3 and 4 were fed with diets A, B, C and D respectively and their fasting blood glucose level were determined at intervals for a period of twenty-one days. Group 3 had the lowest blood glucose level range (80 to 100 mg/dL) more than diets A and B which has blood glucose level range of 82 to 109 mg/dL and 103 to 124 mg/dL respectively. This is an indication that the particle size of diet C is the best in the management of diabetes among the other diets. Therefore, the particle size of diet C is more effective in the management of diabetes than that of diets A and B. However, the three diets were able to reduce the blood glucose level to normal.

Chemical Composition, Quality Indices and Viscosity of Edible Oils from Blends of African Oil Bean Seed Oil and Sesame Seed Oil

2024-06-15T08:17:07+07:00

This study adopted the concept of blending in developing and evaluating the properties of binary oil blends from African oil bean seed oil and sesame seed oil. Vegetal oils were extracted from African oil bean seeds (AB) and sesame seeds (SS) through Soxhlet extraction and blended in the following proportions: AB100:SS0, AB0:SS100, AB90:SS10, AB80:SS20, AB70:SS30, AB60:SS40 and AB50:SS50 respectively. The chemical, quality and viscosity properties was investigated. Findings from this study showed that the chemical composition decreased from 124.55 to 101.28 g of I2/100 g, 208.67 to 191.29 mg KOH/g, 1.94 to 1.62% for iodine, saponification and unsaponifiable matter values while quality properties improved with reduction in PV, FFA, pAV, AV and totox value from 3.12 to 2.79 meq O2/kg, 4.04 to 2.99%, 0.57 to 0.31, 8.08 to 5.99 mg KOH/g and 6.81 to 5.88 respectively as the proportion of sesame seed oil increased in the blended oils from 10 to 50%. Viscosity results at 50C and 370C increased in the studied samples from 560.00 mPa.s in AB100:SS0 to 635.00 mPa.s in AB50:SS50 and from 91.00 mPa.s in AB100:SS0 to 103.00 mPa.s in AB50:SS50 respectively. Conclusively, binary oil blends had better oil properties and could be optimized for food applications
