The present work looks at the role of phytate-degrading Pediococcus pentosaceus CFR R123 application in functional foods to evaluate the fate of phytate and calcium solubility during fermentation. Under standard conditions, CFR R123 grown in modified MRS containing sodium phytate CFR R123 showed 43% degradation of sodium phytate in 15 minutes. Fermentation of malted finger millet seed coat (MFSC) and soya milk (SM) with CFR R123 for 12 h resulted in 5.6-12% phytate degradation and a notable increase in calcium availability (125%) was observed. The isolate CFR R123 was found to decrease the phytic acid levels resulting in increased levels of calcium during MFSC and soya milk fermentation. This study introduces phytate-degrading P. pentosaceus CFR R123 that can be employed as a starter culture as well as an ingredient of functional food to provide nutritive benefits to the consumer with a natural phenomenon.
本研究探讨了植酸降解戊糖片球菌 CFR R123 在功能性食品中的应用,以评估其在发酵过程中植酸和钙溶解度的变化。在标准条件下,CFR R123 在含有植酸钠 CFR R123 的改良 MRS 中生长 15 分钟后,植酸钠的降解率达到 43%。用 CFR R123 发酵发芽的小米种皮(MFSC)和豆浆(SM)12 小时后,植酸降解率为 5.6-12%,钙的生物可利用率显著提高(125%)。该分离株 CFR R123 可降低植酸水平,从而在 MFSC 和豆浆发酵过程中提高钙水平。本研究介绍了可作为发酵剂和功能性食品成分的植酸降解戊糖片球菌 CFR R123,它可以为消费者提供营养益处,这是一种自然现象。
