The aim of this study was to understand the effects of different ultrasound conditions on dietary fiber, phytic acid, total phenolics content, water and oil binding capacity, antioxidant capacity and phenolic acid composition of hull from green and red lentils (Lens culinaris), faba bean (Vicia faba), and pea (Pisum sativum). The highest and the lowest total dietary fiber content was observed in red lentil and faba bean hulls, respectively. Insoluble dietary fiber contents of the untreated pulse hulls were above 66% regardless of the pulse type...

Peaches are known for their palatable flavor and abundant nutrients. However, peaches are perishable, and the existing preservation techniques for peaches are still immature. To further extend the shelf life and prevent nutrient loss of perishable peaches under ambient temperature in summer (approximately 25-32 °C), we conducted experiments wrapping peaches (Prunus persica cv 'Baihua') in single- and composite-treated vegetal fibrous papers that contained calcium carbonate, phytic acid, Na-alginate and vitamin C...

BACKGROUND: Phytic acid is considered as an antinutrient. Ca(2+) addition during germination has been proved to be an effective method for reducing phytic acid content in seeds. In this study, mung bean sprouts were treated with LaCl3 (La), verapamil (VP), ruthenium red (RR) and CaCl2 to explore the effect of Ca(2+) influxes on phytic acid degradation. RESULTS: 6 mM CaCl2 significantly improved extracellular and intracellular calcium precipitates and calcium content, elevated phytase and acid phosphatase activity and further enhanced phytic acid degradation...

Seasonal recycling of nutrients is an important strategy for deciduous perennials. Deciduous perennials maintain and expand their nutrient pools by the autumn nutrient remobilization and the subsequent winter storage throughout their long life. Phosphorus (P), one of the most important elements in living organisms, is remobilized from senescing leaves during autumn in deciduous trees. However, it remains unknown how phosphate is stored over winter. Here we show that in poplar trees (Populus alba L.), organic phosphates are accumulated in twigs from late summer to winter, and that IP6 (myo-inositol-1,2,3,4,5,6-hexakis phosphate: phytic acid) is the primary storage form...

Three-dimensional functionalized graphene monoliths (3DFGMs) have attracted intensive attention as energy storage materials due to their unique interconnected porous structure, good electrical conductivity, excellent mechanical strength, and pseudocapacitive characteristic. Herein, we report a facile, green and low-cost strategy through a simple, one-step electrochemical process in a phytic acid solution to fabricate a 3DFGM. The 3D porous structure and functionalization of graphene can be obtained simultaneously...

Okara (soybean residue) is a highly perishable food processing by-product from soymilk and tofu manufacture. It contains a large proportion of insoluble dietary fibre (40-60% on a dry basis), as well as digestion-resistant proteins, trypsin inhibitors and phytic acid. These factors contribute lead to the under-utilisation of okara. To improve the overall nutritional quality of okara, sequential saccharification of okara by Celluclast® 1.5L (cellulase) or Viscozyme® L (cellulase and hemicellulase) and fermentation by the yeast Yarrowia lipolytica were performed...

Removal of toxic dyes from wastewater has become a hot topic in both academic and industrial fields since there is growing concern about the threat of sewage to human health. Herein, we demonstrate that the three-dimensional porous polyacrylamide-phytic acid-polydopamine (termed as PAAM/PA/PDA) hydrogel can be served as reusable adsorbent with high efficiency for either anionic or cationic dyes. Using methyl blue (MB), methylene blue (YMB), methyl violet (MV) and neutral red (NR) as model dyes, we investigate the effect of pH, temperature, dye concentration, and PAAM/PA/PDA hydrogel mass on the adsorption...

Iron (Fe) deficiency is a major human health concern in areas of the world in which diets are often Fe deficient. In the current study, we aimed to identify appropriate methods and optimal dosage for Fe fortification of lentil (Lens culinaris Medik.) dal with FeSO₄·7H₂O (ferrous sulphate hepta-hydrate), NaFeEDTA (ethylenediaminetetraacetic acid iron (III) sodium salt) and FeSO₄·H₂O (ferrous sulphate mono-hydrate). We used a colorimetric method to determine the appearance of the dal fortified with fortificants at different Fe concentrations and under different storage conditions...

Diets very rich in cereals have been associated with micronutrient malnutrition, and the biofortification of them, has been proposed as one of the best approaches to alleviate the problem. Durum wheat is one of the main sources of calories and protein in many developing countries. In this study, 46 durum varieties grown under full and reduced irrigation, were analyzed for micronutrients and phytate content to determine the potential bioavailability of the micronutrients. The variation was 25.7-40.5mg/kg for iron and of 24...

Although application of Zn combined with macronutrients (K, P, and N) can be used to fortify wheat grain with Zn, little is known about their interactions when foliar application is employed or the influences of common soil fertility management practices (e.g. N and straw management) on their efficiency. Therefore, the effects of foliar-applied Zn and N, P, or K on grain nutritional quality (especially Zn) were investigated in wheat grown under different soil N rates at two sites with (Sanyuan) or without (Yangling) employing straw return...

The aims were to optimise pearling process of red and white sorghum by assessing the effects of pearling time and grain moisture on endosperm yield and flour ash content and to assess nutrient and anti-nutrient losses produced by pearling different cultivars in optimised conditions. Both variables significantly affected both responses. Losses of ashes (58%), proteins (9.5%), lipids (54.5%), Na (37%), Mg (48.5%) and phenolic compounds (43%) were similar among red and white hybrids. However, losses of P (30% vs...

In this study, chia seed flour (CSF) was used in gluten-free noodle formulation at different levels (0, 10, 20 and 30%, w/w) with and without diacetyl tartaric esters of mono (and di) glycerides (DATEM). Chemical, nutritional, sensory properties and cooking quality of gluten-free noodle samples were investigated. Protein, fat, antioxidant activity and total phenolic content of gluten-free noodles increased by 1.7, 5.5, 2.6 and 2.0 times at 30% usage level of CSF as compared to control sample. Phytic acid and phytate phosphorus content increased from 168...

In present study, three varieties (G 80, Ageta 112 and HG 365) of guar bean (Cyamopsis tetragonoloba) were analysed for proximate analysis and were processed by different methods (dehusking, soaking, autoclaving, extrusion and germination) to reduce its antinutritional factors. Processed guar flours were studied for antinutritional factors (tannins, phytic acid and polyphenols) and protein fractions. The highest protein, ash and polyphenols contents were observed in Ageta 112. G 80 contained the lowest tannin and phytic acid content...

RATIONALE: The phosphorus storage compound in grains, phytic acid, or myo-inositol hexakisphosphate (IP6), is important for nutrition and human health, and is the most abundant organic phosphorus compound in soils. Methods for its determination have traditionally relied on complexation with iron and precipitation, acid digestion and measurement of phosphate concentration, or (31) P NMR spectroscopy. Direct determination of phytic acid (and its homologues) using mass spectrometry has, as yet, found limited application to environmental or other complex matrices...

Chickpea (Cicer arietinum L.) is the third most important food legume crop. Seed size is the most economically important trait for chickpea. To understand the genetic regulation of seed size in chickpea, the present study established a three-way association of CT repeat length variation of a simple sequence repeat (SSR) in myo-inositol monophosphatase gene (CaIMP) with seed weight and phytic acid content by large scale validation and genotyping in a set of genetically diverse germplasm accessions and two reciprocal intra-specific mapping populations...
