Fermented bean curd

Effect of Pretreatment on Lactic Acid Fermentation of Bean Curd Refuse with Simultaneous Saccharification... 

Dry bean curd refuse was used as the substrate in the lactic acid fermentation with simultaneous saccharification (SSF). The dry bean curd refuse was preliminarily sieved under a mesh size of 250 II m. It contained 12.3% water, 4.0% ash, 0.8% lipid, 29.3% protein, 53.6% carbohydrate, respectively, in weight basis. The cellulase derived from Aspergilltis niger with an enzymatic activity of 25,000 units/g (Tokyo Kasei Industry Inc.) was employed as the saccharification enzyme. 

Lactic acid fermentation of HCl-pretreated bean curd refuse substrate with ESS... 

Table 1 shows the dry weight of substrate, and amounts of HCl aqueous solution for pretreatment, cellulase and suspension broth for the lactic acid fermentation with ESS. The initially supplied amount of bean curd refuse in dry weight basis was changed from 10 to 150 g to examine the influence of substrate loading. The amount of cellulase was increased against initial substrate loading. And also, the amoimt of 0.1 mol/1 HCl was increased against... 

For lactic acid fermentation of bean curd refuse with simultaneous saccharification, it is found that the pretreatment of the substrate using 0.1 or 0.2 mol/l HCl aqueous solution with heating at niTi for 30 min efficiently solubilized the raw material and significantly enhanced the enzymatic saccharification followed by the lactic acid fermentation. The amount of initial load of bean curd refiise in dried state could be increased up to 75 g/1 in a batch fermentation, and the finally attained lactic acid yield and its concentration were as high as 87.0% and 45.8 g/1, respectively. 

Monoamine oxidase inhibitors are not commonly prescribed to Asians, because many traditional Asian foods, including fermented bean curd, soy sauce, and fermented soybeans, contain relatively high levels of tyramine (a pressor amine), ranging from 0.02 to 43.0 pmol/g (Sung et al. 1986). Because the vast majority of Asians are fast acetylators (Whitford 1978), the metabolism of phenelzine may be increased in Asians, resulting in higher dose requirements than in Caucasians. 

Fermentation has been known and commercially exploited for centuries. Products like spirit, liquor, wine, beer, and other alcoholic beverages vinegar cheese and yogurt miso, soy sauce, and fermented bean curd ham and sausage fish sauce cured vanilla beans, tea, and cocoa pickles and sauerkraut dough, bread, and other bakery products have special flavor notes that can also be used as seasonings. 

Isoflavones (2) have usually been found as small amount phytochemicals from the legumes, grains and vegetables, and their processed foods such as traditional tofu and Indonesian tempeh which is a traditional soy product originally from Indonesia [Indonesian tempeh is made by a natural culturing and controlled fermentation process that binds soybeans into a cake form of similar to a very firm vegetarian burger patty], miso, natto, soya milk, bean curds and bean sprouts. 

Food sources of phylloquinone for man (Table 1) include green leafy vegetables as the major quantitative source however, its availability for absorption from these foods is thought to be relatively poor. Certain plant-derived oils, notably soya and canola oils, are also rich in the vitamin, which is probably much more readily available from such sources than it is from leaves. Menaquinones are typically obtained from foods, such as cheeses or Japanese natto (fermented bean curd), in which bacterial fermentation has occurred. Smaller amounts of...
