Many types of edible insects in raw and processed forms have been consumed by many cultures globally since time immemorial, particularly developing countries where they are mostly traditionally viewed as a delicacy besides provision nutrition. As food type, two main forms; whole or incorporated various products an ingredient, the choice which is consumer preference driven. Recently, there has lot research interest farming, processing consumption mainly effort to eradicate insecurities...
Edible insects are increasingly being considered as food and feed ingredients because of their rich nutrient content. Already, edible insect farming has taken-off in Africa, but quality safety concerns call for simple, actionable hazard control mechanisms. We examined the effects traditional processing techniques—boiling, toasting, solar-drying, oven-drying, boiling + toasting solar-drying—on proximate composition microbiological adult Acheta domesticus Ruspolia differens, prepupae Hermetia...
Abstract After pulp extraction in fruit processing industry, a significant quantity of mango seed kernels are discarded as solid wastes. These can be ideal raw materials for obtaining extracts rich bioactive compounds with good antioxidant properties. The conversion these wastes into utilizable food ingredients would help reducing environmental problems associated waste disposal. In order to determine their potential use, this study evaluated some the biochemical characteristics and...
Many neglected and underutilized vegetable species such as indigenous African leafy vegetables have been incorporated in human diets since time immemorial, especially sub-Saharan Africa many Asian countries where they greatly contribute to food nutrition security. Due their well-documented superior nutritional quality climate-smartness compared exotic counterparts, of them are currently receiving a lot attention among stakeholders including governments, researchers, nutritionists, consumers...
In this study, cricket chitosan was used as a prebiotic. Lactobacillus fermentum, acidophilus, and Bifidobacterium adolescentis were identified probiotic bacteria. Cricket chitin deacetylated to added either De Man Rogosa Sharpe or Salmonella/Shigella bacterial growth media at the rates of 1%, 5%, 10%, 20% obtain chitosan-supplemented media. The bacteria monitored on after 6, 12, 24, 48 h upon incubation 37 °C. Growth Salmonella typhi in presence evaluated under similar conditions those by...
Abstract Fusarium langsethiae is a toxigenic fungus that was formally described as new species in 2004. This first detailed the 1990s but initially referred to ‘powdery F usarium poae’ having spore morphology similar . poae mycotoxin profile like of sporotrichioides The has been isolated from infected oat, wheat and barley grains reported more problematic former crop rather than latter two. Whilst epidemiology remains unclear, shown produce high levels type‐ A trichothecenes HT ‐2 T toxins...
Street food selling is largely an informal nature of enterprise which a common practice all over the world. In third world countries, this normally unregulated mainly used in solving socio-economic shortcomings through provision ready-to-eat meals at affordable prices as well means providing employment. vended foods are readily available many forms that consumers can choose from, depending on their tastes and preferences, also affordability. Due to this, these foods, one way or another,...
Abstract Fresh juices rich in health and nutritional benefits are valued for their fresh flavor, taste, aroma. These juices' quality however is affected by factors like temperature, light, microbiological contamination significantly changing physicochemical parameters storage stability. Physicochemical analyses of passion fruit, pineapple, mango dark light bottles at 24°C 4°C were conducted Kampala, Uganda 12 days. reduced ( p < .05) stability juices, while no significant changes >...
Chemical, thermal or osmotic pretreatments prior to drying can improve the quality aspects of dried foods. Three were evaluated for antioxidant capacity in two mango varieties viz. Ngowe and apple that dehydrated either, oven (50 65 °C) solar dryer. The properties analyzed included polyphenols, vitamin C, carotenoids, flavonoids total activity. Total polyphenol content was determined through Folin–Ciocalteu method quantified using UV-Spectrophotometer. Vitamin C by HPLC system while...
<title>Abstract</title> The mango processing industry generates peels as byproducts, which are a rich source of bioactive compounds, including pectin. This study aimed to evaluate the impact extraction methods on antioxidants and pectin yields from determine most effective techniques for recovery compounds potential applications in food industry. were extracted using microwave assisted (MAE), enzyme (EAE), ultrasound (UAE) water-bath (WBAE) while was performed MAE, conventional acid (CAE)...
Soymilk is rich in nutrients and isoflavones, could greatly promote nutrition health. However, this product not widely accepted due to an objectionable beany flavor. Several methods involving heat treatment soaking basic solutions prior soymilk extraction have been reported reduce the effects of such treatments on nutritional value isoflavone content soymilk, responses different soybean varieties nutrient by these well studied. The aim study was determine effect three processing protein,...
Abstract Drying is essential in lowering the water activity and increasing shelf stability of perishables. Thus, this study investigated effect pretreatment on retention antioxidant properties color four tomato varieties; that is, Anna F1, Kilele, Prostar Riogrande during drying. Prepared quarters were treated by spraying with 0.5% sodium metabisulfate, calcium chloride, distilled water. The oven dried at 50°C, 60°C, 70°C to 13% moisture content. Lycopene, β carotene, total phenolics, color,...
Abstract Morama bean [ Tylosema escululetum (Burch.)] is a nutrient-dense underutilized legume that can address protein-energy and micronutrient malnutrition in developing countries. An ethnographic study using snowball sampling method was conducted Kweneng, Ghanzi, Southern, Central districts of Botswana. The survey sought to gather document information about demographic characteristics, traditional use, cultural norms, harvesting, processing, preservation, health benefits morama beans. A...
Fusarium head blight (FHB) is a disease of small-grain cereals that has proven negative impact on crop yield, quality and food safety. In this regard, it one the most studied diseases worldwide. This paper reports commonly used artificial sources inoculum inoculation techniques employed in study FHB epidemiology. Spore suspensions grain spawn are popular forms inoculums. Spray technique more than point for delivering inocula to target sites. an advantage over can be detect both Type I II...
