Rabadi fermentation of barley flour-buttermilk mixture (fresh and autoclaved) at 30, 35 and 40°C for 6, 12, 18, 24 and 48 h lowered pH, enhanced titratable acidity and did not change fat and total mineral (Ca, Fe, Cu, Zn, Mn and P) content. Protein content of fermented fresh as well as autoclaved barley flour-buttermilk mixture either decreased or remained unchanged.Rabadi prepared from both types of barley flour at different temperatures and time periods was acceptable; but that which was fermented at 40°C for 48 h was less acceptable in terms of taste.  相似文献

Single as well as mixed culture fermentations by yeasts (S. diastaticus;S. cerevistiae) and lactobacilli (L. brevis;L. fermentum) at 30 °C for 72 h improved the starch and protein digestibility (in vitro) of pearl millet flour significantly. The flour fermented bySaccharomyces diastaticus, a starch hydrolysing yeast, had the highest starch digestibility whereas fermentation bySaccharomyces cerevisiae enhanced the in vitro protein digestibility of the flour significantly. Weaning mixtures prepared from the fermented flour were also found to be organoleptically acceptable.  相似文献

Fermentation of raw as well as autoclaved wheat flour with buttermilk at 30, 35 and 40°C for 6, 12, 18, 24 ad 48h significantly decreased the level of phytic acid; maximum decrease was observed at 40°C for 48h. Starch as well as protein digestibility (in vitro) improved with an increase in temperature and period of fermentation. Phytic acid had a significant (P<0.05) negative correlation with digestibility (in vitro) of both starch and protein ofrabadi.  相似文献

Mixed culture fermentation of pearl millet flour withSaccharomyces diastaticus, Saccharomyces cerevisiae, Lactobacillus brevis andLactobacillus fermentum brought about an improvement in its biological utilisation in rats. Protein efficiency ratio, feed efficiency ratio, apparent protein digestibility, true protein digestibility, net protein utilisation, net protein retention, protein retention efficiency and utilisable protein values in case of pure culture fermented pearl millet four were higher than the control. Feeding of the fermented products did not bring about physiological, histopathological and haematological changes in rats.Chapaties and cutlets prepared from the fermented products were organoleptically acceptable.  相似文献

Protein digestibility was found to be 60.4 to 66.5 percent in raw unprocessed seeds of different pea cultivars. Protein digestibility (in vitro) was improved by the common methods of domestic processing and cooking including soaking, dehulling, ordinary cooking, pressure cooking and sprouting of legume grains. Pressure cooking had more pronounced effect on protein digestibility followed by ordinary cooking, sprouting, soaking for 18 h and (12 h) and dehulling. Pressure cooking of soaked and dehulled seeds was noticed to give most improved protein digestibility.  相似文献

Sequential culture fermentation by yeasts (S. diastaticus orS. cerevisiae) at 30°C for 72 hr and then followed by lactobacilli fermentation (L. brevis orL. fermentum) at 30°C for 72 h more resulted in a significant reduction in phytic acid and polyphenol content of pearl millet flour. Fermentation byS. diastaticus andL. brevis combination almost eliminated phytic acid from pearl millet flour. The combinations ofS. diastaticus with both the lactobacilli reduced phytic acid more effectively than those ofS. cerevisiae. The products fermented byS. cerevisiae andL. brevis and byS. diastaticus andL. brevis combinations had the highest protein and starch digestibility (in vitro).  相似文献

Natural as well as single, mixed and sequential pure cutlure (S. diastaticus, S. cerevisiae, L. brevis andL. fermentum) fermentations of pearl millet flour for 72h lowered pH and raised titratable acidity. The fermentation either decreased or did not change the protein content of pearl millet flour. Natural fermentation increased whereas pure culture fermentation decreased the fat content. Ash content did not change. Natural fermentation at 20°C and 25°C increased whereas at 30°C it decreased the thiamine content of the pearl millet flour. Yeast fermentation raised the level of thiamine two- to three-fold, while lactobacilli fermentation lowered it significantly.  相似文献

UPAS-120, a high yielding and early maturing variety of pigeon peas releasedby the Department of Plant Breeding, CCS Haryana Agricultural University, Hisar contained a significant amount of phytic acid, i.e. 886 mg/100 g. When it was subjected to various domestic processing and cooking methods viz. soaking (6, 12, 18 h), dehulling, ordinary as well as pressure cooking and germination (24, 36 and 48 h), a drastic decrease in level of phytic acid with a remarkable increase in the HCl-extractability of mono, divalent, andtrivalent ions, like calcium, phosphorus, and iron occurred. Germination (48 h) was found to be the best method for decreasing the phytic acid content, i.e.35 to 39 percent less than the control and significantly (p<0.05) increasingthe non-phytate phosphorus and HCl-extractable phosphorus. Pressure cooking of soaked-dehulled pigeon pea also rendered equally good results. The calcium, phosphorus and iron contents of pigeon pea seeds were 197.3, 473.1, and 9.91 mg/100 g, respectively; some losses varying from 3 to 9 percent were noticed when the legume was subjected to soaking, cooking, and germination but the maximum losses, i.e. 23 percent, occurred when the seeds were dehulled. However, HCl-extractability of Ca, P and Fe improved to a significant extent when the pigeon pea seeds were soaked, soaked-dehulled, cooked and sprouted which may have been due to decrease in the phytate content followed by processing and cooking. The significant negative correlations between the phytic acid and HCl-extractability of minerals of processed pigeon pea strengthens these findings.  相似文献

Four high yielding varieties of field (Rachna and RFP4) and vegetable peas (Bonnivielle and Arkal) were studied for their protein quality. Crude protein and true protein content of all four pea varieties varied from 19.5 to 20.6 percent and 18.7 to 19.8 percent, respectively. Non protein nitrogen formed only 3.94 to 4.84 percent of total nitrogen. Globulins were the major fractions followed by albumins and glutelins. All the four varieties of peas had similar methionine and tryptophan content. Lysine content of four pea varieties ranged from 7.56 to 9.65 g per 16 g of N. Cooking brought about an increase in in vitro protein digestibility of peas by 10 percent. The sodium dodecyl polyacrylamidegel electrophoresis of total protein revealed the presence of 22–25 bands with some difference in banding pattern of all four varieties. Some differences were observed in banding patterns of globulin and albumin of all four varieties, suggesting that composition of protein of pea varieties differed.  相似文献

All the pea varieties differed significantly (p<0.05) in their phytic acid content. The field pea cultivars had significantly (p<0.05) higher levels of phytic acid and polyphenols than those of vegetable pea varieties. All the domestic processing and cooking methods could reduce the contents of phytic acid and polyphenols but germination for 48 hours seemed to have a marked lowering effect on the levels of these antinutrients in peas.  相似文献
