This study investigated the effects of culinary methods (boiling and frying) on the proximate composition of an edible insect commonly known as African Palm Weevil (R. phoenicis) Larva(e). The proximate composition (moisture, ash, protein, crude fibre, fat and carbohydrate contents) were determined using standard methodology of the Association of Analytical Chemists (AOAC). Boiling increased the moisture and ash content but, decreased the protein, fat, carbohydrate (p0.05) and the fibre content compared to the raw sample. On the other hand, frying increased the protein and ash contents (p 0.05) but decreased the moisture, fat, carbohydrate and fibre contents compared to the raw. The decrease in moisture content led to a corresponding increase in the protein, and ash contents of the fried sample, which indicates high protein and mineral levels of the larvae. Also, the lowest moisture content recorded in the fried sample compared to the raw and boiled sample was an indication of reduction of microbial spoilage, and longer storage shelf life of this edible larva. Therefore, frying is recommended as the best culinary method for healthy diet.

The study was designed to investigate the effects of freezing periods and the combination of packaging with or without turmeric on the proximate composition of whole and sliced Labeo bata. The samples were subjected to 28 days of frozen (-20 °C) storage periods and analyzed for proximate composition such as moisture, protein, lipid and ash at intervals of 0, 14 and 28 days. Data obtained was subjected to analysis of variance (ANOVA) at 95% significant level. Different preservation periods and methods significantly affected the nutritional composition of fresh fish. Moisture, protein, lipid and ash content decreased with increasing storage periods when compared to the fresh fish as control. The highest percentage of protein was found in turmeric-treated whole fish preserved in polythene, C4, after the 14th (15.70±0.14) and 28th (15.27±0.21) day. On the other hand, the lowest percentage (14.01±0.10 and 13.22±0.18 for the 14th and 28th day, respectively) was found in sliced fish preserved without polythene, C5. In conclusion, the turmeric-treated whole fish preserved in polythene retained fish nutrients and ensured its good quality and composition longer than other treatments, thereby extending the shelf life during frozen storage.

Proximate composition of chapila fish (Gudusia chapra) was determined using two different treatments of smoke-drying. In salt treated smoke-dried chapila (S-C), moisture, crude protein, lipid and ash contents were found 5.31%, 46.47%, 29.05% and 19.92% respectively. The same parameters were 6.77%, 45.24%, 30.52% and 18.71% respectively in case of salt-garlic treated smokedried chapila (S+G-C) fish. During storage at room temperature (26-320C), the percentage of moisture was increased significantly whereas crude protein, lipid and ash contents were decreased. The values of moisture (%) content were increased 9.91% (8th months) in S-C and 10.74 % (16th months) in S+G-C respectively. The values of protein (%) content were decreased 44.81% (8th months) in S-C and 42.66% (16th months) in S+G-C respectively. Values of fat and ash (%) content were decreased 28.55% and 18.01% (8th months) respectively in S-C and 28.75% and 17.34% (16th months) respectively in S+G-C. The overall study showed that the smoke cured fish treated with salt-garlic had longer shelf life and found better for preservation.Bangladesh J. Zool. 42(2): 205-209, 2014

Cubing machines in food processing have evolved over the years, which have made products like Star®, Knorr®, and Chicken® bouillon cubes become commercially available today, even in many parts of Africa. On the other hand, the fermented mesquite seed “okpeye” food condiment, traditionally produced by well-trained artisans and widely utilised in Nigeria, requires further product development in order to compete with bouillon cubes. Quality comparisons between the cubed “okpeye” condiment and commercially available bouillon cube products have not yet been reported. Therefore, cubing fabrication/costing and machine performance on African fermented “okpeye” condiment quality attributes, compared with commercial bouillon types, were done. The processing of mesquite seeds into the “okpeye” condiment resembled those of artisans. Bouillon cube products involved the Star®, Knorr®, and Chicken® types. Quality attributes involved proximate, micronutrient, phytochemical, and microbial aspects. Results showed that the throughput capacity of a cubing machine increased with an efficiency of 48 condiment cubes/min, forming properly without separation. Across all studied samples, the protein, ash, moisture, crude fat, crude fibre, and carbohydrate contents were in the range of 1.45–42.50%, 5.29–6.75%, 8.50–12.29%, 2.56–18.54%, 2.45–3.19%, and 18.16–25.56%, respectively. The protein, fat, moisture, calcium, iron, magnesium, and manganese contents of “okpeye” condiment were significantly higher (p < 0.05) than those of bouillon cubes. Fair amounts of vitamins B1, B2, B3, and E were found, with the “okpeye” condiment higher in vitamin E. Besides the flavonoids (0.12–0.18%), alkaloids (0.08–0.15%), saponins (0.19–0.55%), and tannins (0.69–0.93%) present, the microbial loads were similar (p > 0.05) across all samples. Indeed, the “okpeye” condiment can be cubed, and by quality attribute, it competes favourably, and very promising substitute to commercial bouillon cubes.

This study was conducted to evaluate the effect of oven drying on the proximate composition and rehydration characteristics of shellfish. Shellfish studied included rough and smooth periwinkle, oyster and whelk. Proximate composition of the fresh samples were determined. Then dried in the oven to a moisture content of 10% and further rehydrated with distill water in sample water ratio of 1:40 and allowed to equilibrate. Proximate composition of the fresh shellfish showed that moisture content ranged from 82.38 to 69.24% with fresh smooth periwinkle having the highest moisture value while whelk had the lowest. The results also showed that whelk had the highest values for ash (2.92%), crude protein (18.83%) and crude fibre (3.71%) when compared to other samples. On rehydration, a moisture loss of 11.75%, 13.28%, 19.24% and 22.04% were observed for rough periwinkle, smooth periwinkle, oyster and whelk, respectively. The results for rehydration indices revealed that dehydration ratio was significantly (p<0.05) high for whelk (1.44), followed by oyster (1.29), rough periwinkle (1.23) and lastly, smooth periwinkle 1.20. Rehydration ratio of whelk (1.47) was equally significantly higher, followed by oyster (1.33) and the least were rough and smooth periwinkle (1.17). For coefficient of reconstitution, oyster recorded the highest value of 1.03, followed by whelk 1.02, rough periwinkle 0.95 and smooth periwinkle 0.98. Rate of water imbibition revealed a sharp increase in the water content of smooth periwinkle up to 240 min and thereafter, it slowed down until equilibrium was reached. In terms of rough periwinkle, oyster and whelk; water imbibition took place with rehydration time up to 300 min, 210 min and 270 min, respectively, thereafter they slowed down. The results have demonstrated that the rate in which oven drying affect the physical and nutritional qualities of shellfish differs.
