摘要

Recovery of water and soluble materials of soybean soaking water was done using a membrane system consisting of nanofiltration (NF) and reverse osmosis (RO). Retentates from NF and RO were collected when the weight concentration ratio (WCR) had reached 7 and 6, respectively, which was equivalent to a total WCR of 3.5 for the combined NF-RO system. The retentates were inoculated with the probiotic cultures of Lactobacillus acidophilus CCRC 10695 and Bifidobacterium longum CCRC 11847. Under the fermentation condition (pH 5.5, 37 degrees C), up to 7 g/L organic acids, mostly lactic acid, could be harvested after 24-h fermentation. The fermentation broth was centrifuged to remove cells, pasteurized, and then formulated to a test drink, which was well accepted as compared with market samples. The membrane-permeated water was nearly neutral in pH with a Hunter L-* value above 90, which could possibly be reused in the plant site for cleaning and soaking purpose. [References: 27]
