چکیده
Nutritional and anti-nutritional compositions of defatted Nebraska hybrid hazelnut meal" (2011). Summary Defatted meal of hybrid hazelnuts may have potential food and value-added industrial applications. The proximate composition, mineral elements, amino acid profile and anti-nutritional factors (total phenolics, tannins, condensed tannins and phytates) of defatted meals of ten Nebraska hybrid hazelnut genotypes were investigated. Excluding the amino acid profile, the nutritional and anti-nutritional compositions of the meals differed significantly, with high protein, carbohydrate, neutral and acid detergent fibre concentrations and energy value. Mineral concentrations were higher than those previously reported. K was the most abundant mineral element, followed by P, Ca and Mg. Seven essential amino acids accounted for approximately 27.8% of the total amino acid contents. Tryptophan was not detected. All essential amino acid contents were significantly lower than the reference levels recommended for human and animal consumption. The high levels of anti-nutritional factors, such as total phenolics, tannins, condensed tannins and phytate in the meals, could reduce protein and mineral bioavailability.

متن کاملStudies on the Production of Defatted Sunflower Meal with Low Polyphenol and Phytate Contents and its Nutritional Profile
A simple process was developed for making low poly phenol and phytate sunflower meal. This meal contains 58% proteins, 0.2% phytates and 0.3% poly phenols. This meal may be used directly for food fortification to enrich the nutritional profile of traditional diets and also a feeding stock for protein isolation.

Three different varieties of cottonseed meal (CSM) were evaluated to measure the apparent digestibility coefficient (ADC) of the nutrients using chromic oxide (Cr2O3) as an indigestible marker. Five experimental diets were prepared and mixed with 1% of Cr2O3, 2% of mineral and vitamin each of which were premixed. Diet 1 was used as the control diet. Diets 2, 3, 4 and 5 were formulated using 70...
