A study was made on preservation techniques of cauliflower to get better shelf life, organoleptic qualities and economic return to farmers. Two processes of preservation namely sun drying and oven drying were compared. For the purpose, cauliflower purchased from local market were undergone processes of drying at normal room temperature, weighing and cutting into 3-4 cm long pieces, blanching and removing of excess water. Afterwards, the samples of blanched cauliflower were sun dried at 30-350 C and oven dried at 50-600 C separately. The dehydrated samples were then analyzed for proximate composition such as moisture, ash, fat, crude fiber, crude protein and carbohydrate content. For sensory evaluation cauliflowers recipes from oven dried and sun dried samples were prepared. Unit cost of processed cauliflower in case of dehydration by sun drying was Rs. 68.50 compared to oven dried as Rs.70.70 per kg. Rehydration ratio of sun dried was 5.9:1 where as in oven dried sample was 5.8:1. The moisture content was found to be higher in sundried sample (5.5%) as compared to oven dried sample (5.0%). Ash content (7.75%) was higher in oven dried sample compared to 7.25% in sun dried sample. As regards proximate composition of dehydrated cauliflower, fat content was observed to be similar in both methods of drying where as crude fiber content were 12.0% and 10.0% in oven dried and sun dried samples respectively. Crude protein contents were found to be 12.75% and 13% in oven dried and sun dried samples respectively where as carbohydrate contents were 60.50% and 62.25% respectively. Organoleptic properties such as colour, flavor, texture and taste of the recipes prepared from the dehydrated cauliflower were found to be in highly preferable range of 30 respondents upto 6 months period of dehydraion. As investigated from the above facts, shelf life, organoleptic qualities and nutrient composition of sun dried and oven dried cauliflower samples were observed to be almost similar. Adding to this sun drying can be done easily by rural women folk, hence this method can be advocated as preferred technique for the farmers of Khagaria district. Women folk earned substantial benefit by marketing of sundried cauliflower.

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.

The application of fermentation is one of methods to increase food quality biologically. Availability of Jatropha curcas residual from oil factory be focused as a soybean meal or fish meal replacement. On the other hand, J. curcas residuals possess a toxic compound as well. This study aimed to examine the effect of Aspergillus niger on the nutrition and harmful content of J. curcas as a potential ingredient of feed. In brief, J. curcas residual was fermented with a detoxification method at 3 d, 5 d, and 7 d. Crude protein, fat, and crude fiber content were assessed to discover the biological responses of J. curcas post–fermentation while phorbol ester was evaluated to toxic content post–detoxification. The results showed that crude protein and fat content were highest on 7 d post–fermentation but it was no significant difference (p > 0.05). While crude fiber content showed significant difference which the 3 d fermentation had the highest content of fiber. For phorbol ester content, 3 d fermentation showed a better result than the control group (p < 0.05). The present findings suggest that A. niger is recommendable as starter to reduce fiber and toxic content of J. curcas residual at 3 d fermentation.

Background: Turmeric and red chili are the common spices used for cuisine preparation in Bangladesh. Commercially packed turmeric and red chili might have decreased nutrient contents compared to raw turmeric and red chili. Aims:  The study aimed to compare some of the nutrient values between the commercially packed and raw turmeric and red chili. Methods: Commercially packed turmeric and red chili with different brand names (Radhuni, Tiger and Pran) and in raw turmeric and red chili were purchased from local market. Proximate analyses - dry matter (DM), crude protein (CP), crude fiber (CF) and mineral contents were performed. The total phenolics and total tannin contents were determined using appropriate methods. Results: The proximate analysis results showed that both Radhuni (97.56 mg/g) and Tiger (97.28 mg/g) turmeric revealed significantly higher content of DM (p<0.001). No notable difference was observed in CP value. Crude fiber value displayed significantly highest value (p<0.001) in Tiger brand (4.96 mg/g) and the lowest in Radhuni brand (1.76 mg/g). Mineral content was significantly (p<0.05) highest in raw turmeric (9.97 mg/g). A significantly higher amount (p<0.001) of DM in packed chili was recorded. Tiger chili contained significantly higher amount of CP (6.02 mg/g) and CF (9.31 mg/g) while Radhuni contained the lower amount of CP (4.81 mg/g) and CF (2.48 mg/g). Raw chili had significantly higher amount of ash (13.24 mg/g). Examination revealed significant level (p<0.001) of total phenolics in acetone extracts of Tiger turmeric and chili powder. Significant amount of tannin was found in raw turmeric (33.89 µg/g; p<0.005); however, Pran brand of turmeric had the lowest amount of tannin (9.53 µg/g). Tannin content recorded in red chili was significantly (p<0.001) higher in commercially packed Tiger brand which was 16.57 µg/g compared to raw red chili (3.315 µg/g). Antioxidant analysis showed higher antioxidant activity in both raw turmeric and red chili powder. Conclusion:  Tiger brand turmeric ensures the standard moisture, fiber and protein contents as well as the amount of phenolics and tannin.

Purpose – This paper aims to assess the potential of date fruit powder as a refined sugar replacer in rock buns to help promote and diversify the utilization of date fruit. Design/methodology/approach – Date fruit pulp was sun dried, milled into powder, sieved and its proximate composition determined. Refined sugar in rock buns was replaced with date fruit powder at 0, 50, 80 and 100 per cent levels. The samples were then subjected to proximate, mineral and sensory evaluation. Findings – Date fruit powder had 1.47 per cent crude fiber and was high in carbohydrate (82.15 per cent). Carbohydrate content of samples decreased (48.55-29.72 per cent), while crude protein (6.78-9.97 per cent), crude fat (22.74-33.66 per cent) and crude fiber (0-0.49 per cent) contents increased with an increasing substitution of date powder. Of all, 0 and 50 per cent substituted rock bun samples were the most preferred. Date powder significantly (p < 0.05) increased the potassium (0.55-1.57 per cent), calcium (0.08-1.08 per cent) and iron (0.53-0.625 per cent) contents of the samples. Originality/value – This research assessed the potential of date fruit powder as a replacer of refined sugar in rock buns, as it remains an underutilized commodity in Ghana. Replacing 50 per cent of refined sugar improved the nutrient composition of rock buns, thereby making date fruit powder a nutritious sugar replacer which could be used in pastry products. This when adopted would diversify the utilization of date fruits while providing good nutrition to consumers.

Under the present investigation, ginger was produced at the instruction cum research plots of the Department of Plantation Crops and Processing, Faculty of Horticulture, Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar, West Bengal. The experiment was laid out in a factorial CRD. The study was undertaken with four ginger varieties namely Gorubathan, Suprabha, Suruchi and Suravi to evaluate the effect of different drying methods (sun drying, hot air drying at 50OC, 60oC and 70oC and microwave drying on time required for drying to a moisture content of 8 – 10% and to chemical composition (essential oil, oleoresin content and crude fiber content) of the end product. Results shown that Gorubathan variety has the highest essential oil (2.243%) and oleoresin content (14.840%) among the four varieties in this study, highest crude fiber content (5.253%) was observed in Suprabha and highest dry recovery (25.77%) was obtained from Suravi variety. In hot air drying, with increase in temperature essential oil, oleoresin and crude fiber content in dry ginger as well as dry recovery reduced. With high dry recovery (25.77%), essential oil (2.037%) and oleoresin content (13.510%) and moderately low crude fiber content (4.637%), it can be concluded that Suravi variety is best suitable for producing dry ginger. Apart from microwave drying, sun drying can be recommended as better practice, when hygienically conducted, based on essential oil and oleoresin content.

Abstract Feed is one of the factors determines the success of a fish farm. Feed-quality feed stuffs that require high quality also, which still rely on imports, especially fish meal and soybean oilcake. Effort to reduce dependence on import of feed stuff is searching for alternative feed stuffs that the quality is quite good, cheap, easily obtained and can reduce cost of production. One of the feed stuff as an alternative source of animal protein feed that need to be examined is the prawn waste. Prawn waste meal enough potential to be used as fish feed with a crude protein content 45.29% and 17.59% crude fiber was alternative feed stuff for fish meal. The usage of prawn waste as a feed stuff should be through the handling and processing to further improve the nutrient value of waste. Prawn waste processing in this research consists of two ways, that is waste cooking prawn on the high pressure (100 kpa), and conducted fermentation by using probiotic. The existence of microorganisms activity during the fermentation process will cause changes of feed stuffs either through physically and chemicals. Probiotic is a microbe colony that is rich in celulolytic, lignolytic and proteolytic bacteria. The aim of this research is to know the influence probiotic on the prawn waste cooked with high pressure to increase the protein content and to decrease the crude fiber content. Method as used in the research is experimental method. Experiment design that used at research is Completely Randomized Design with 4 treatments and replicates 5 times. To get the data is conducted procsimat analysis on the crude protein content and crude fibers from each experimental unit. That result data analyzed with the Analysis of Varian continued with Duncan’s Multiple Range Test. The results of research is known that dosaged probiotic at process of prawn waste cooked fermentation not different to crude protein contents of the waste cook fermented prawn. Crude fiber content of the waste cook fermented prawn using probiotik (P1, P2, P3) has decreased if compared with waste cooking fermented prawn without using probiotic (P0)
