Stability of concentrated extracts of Hibiscus sabdarifa L. calyx during storage at different temperatures

Hibiscus sabdariffa L. (Malvaceae) calyx is a valuable food resource in Africa. This herb is rich in phenolic compounds and a good source of natural antioxidants. Concentrated extract prepared with Hibiscus sabdariffa L. calyx is commonly used in traditional African and Asian diets and medicines. However, the organoleptic properties of these extracts are degraded during storage. Therefore, the stability of these...

Effect of pretreatments on the microbial and sensory quality of weaning food produced from blends of sorghum and soybean

This study investigated the effect of pre-treatment on the microbial and sensory quality of weaning foods produced from blends of sorghum and soybean. Sorghum and soybean were fermented, roasted and fermented/roasted, then milled into flours. Untreated sorghum and soybean flours were also produced separately and serve as the control. A portion of sorghum was malted and milled to obtain malted sorghum flour of which 5%...

Production and functional property of maize-millet based complementary food blended with soybean

Traditional complementary foods are mainly based on cereal grains which when cooked get gelatinized and swollen thereby making the diet viscous and bulky for infants and young children. This study was carried out to investigate the effect of fermentation, germination, and roasting methods on the functional properties of maize-millet-soybean mix with a view to producing less bulky and nutrient dense complementary food....

Freeze and spray drying of Scaptotrigona bipunctata (Lepeletier, 1836) pollen - development and physicochemical characterization

This study was carried out to evaluate human consumption of the pollen of Scaptotrigona bipunctata colonies stored in pots; it was lyophilized and spray-dried in arrays of arabic gum and hydrolyzed collagen which have been widely applied to get products with best technological features and highest  biological activity. After the samples were prepared they were evaluated by physicochemical analysis, and the data...

Enhancement of eritadenine production using three carbon sources, immobilization and surfactants in submerged culture with shiitake mushroom (Lentinula edodes) (Berk.) Singer)

In this study, the effect of three carbon sources (mannitol, minced potato and sucrose), two immobilization substrates (alginate and wood cylinders), and three surfactants (Tween 20, Tween 40 and Tween 80), were evaluated on eritadenine production using shiitake (Lentinula edodes) mycelium under submerged cultivation, in shake flasks within 20 days. Eritadenine and biomass were measured by HPLC and gravimetrically,...
