Abstract Kunu is a millet-based, non-alcoholic, and non-carbonated energy beverage commonly consumed in the northern part of Nigeria. The nutrients composition, antioxidant properties, sensory characteristics instant kunu made from pearl millet supplemented with African locus bean pulp (ALBP) were evaluated this study. Instant was produced 5–25% ALBP replacement for freeze-dried. A control samp...

BACKGROUND: Phosphorous is one of the expensive nutrients in poultry feed. Therefore, improving the bioavailability of this nutrient in feed ingredients could be effective for lowering the cost of feed. OBJECTIVE: This study was performed to evaluate the effect of pre-treatment of feed ingredients by commercial enzymes and different levels of pH on releasing of phosphorus from phytate under in ...

Plant seeds that have high phytate content are used as animal feed. Phytases, enzymes that catalyze the breakdown of phytate into inorganic phosphorus and myoinositol phosphate derivatives, have been intensively studied in recent years and gained immense attention because of their application in reducing phytate content in animal feed and food for human consumption, thus indirectly lowering env...

Previous reviews have covered our work on the efficacy of a new E. coli-derived phytase (expressed in yeast) for releasing phytate-bound phosphorus (P) present in corn-soybean meal diets for young pigs, growing-finishing pigs, broiler chicks and laying hens (Baker and Augspurger, 2002; Augspurger, 2003; Augspurger et al., 2003a). It is not our intent to repeat this information, but instead to p...

Five copper (Cu) sources were studied at pH 2.5, 5.5, and 6.5 to determine how Cu affects phytate phosphorus (PP) hydrolysis by phytase at concentrations up to 500 mg/kg diet (60 min, 40-41 degrees C). Subsequently, Cu solubility with and without sodium phytate was measured. Adding Cu inhibited PP hydrolysis at pH 5.5 and pH 6.5 (P < 0.05). This inhibition was greater with higher concentrations...

Techniques have been developed to produce microbial phytase for addition to diets for simple-stomached animals, with the aim to improve phosphorus availability from phytate-P in plant sources. The activity of the crude microbial phytase showed pH optima at pH 5.5 and 2.5. The enzyme was able to degrade phytate in vitro in soya-bean meal, maize and a liquid compound feed for pigs. When microbial...

Phytate is the primary storage form of phosphate in plants. Phytases from microbial sources are supplemented to feedstuff of monogastric animals to increase the uptake of phytate phosphorus. The use of microbial phytase is associated with high production cost and also requires special care in feed processing. Expression of phytase in transgenic plants is an alternative approach to the productio...
