Described herein are improved methods of pretreating lignocellulosic biomass. One aspect of the invention relates to a two-stage pretreatment process comprising a relatively low severity steam treatment, a controlled pH pretreatment, or autohydrolysis, followed by hydrolysis with dilute acid or hot water at a relatively low temperature. In certain embodiments, the methods increase hemicellulose sugar yields, substrate digestibility, and suitability for fermentation as compared to steam explosion or acid hydrolysis alone. The two-stage pretreatment processes also employ few chemicals, minimizing the costs associated with pretreatment of lignocellulosic biomass. Moreover, the two-stage pretreatment process may expand the range of suitable feedstocks for bioethanol production.

The present invention relates to a method for producing a fermented milk, including: performing fermentation using both bacteria belonging to the genus Bifidobacterium and bacteria belonging to the genus Lactococcus as lactic acid bacteria, wherein the bacteria belonging to the genus Lactococcus have the following bacteriological properties: (1) fermentability which curdles a 10% (W / W) reconstituted skim milk medium when cultivated at a temperature of 25° C. to 37° C. for 16 hours; (2) Bifidobacterium longum growth-promoting properties which lead to a viable count of Bifidobacterium longum of 5×108 CFU / g or more, when co-cultivated with Bifidobacterium longum in the 10% (W / W) reconstituted skim milk medium until the pH thereof is 4.4 to 4.6; and (3) Bifidobacterium longum survivability-improving properties during storage, which lead to a survival rate of Bifidobacterium longum of 30% or more, after co-cultivation with Bifidobacterium longum in the 10% (W / W) reconstituted skim milk medium until the pH thereof is 4.4 to 4.6, rapid cooling, and two weeks storage at 10° C., and also relates to a fermented milk prepared by the production method.

It is intended to provide a method for ensuring healthy fermentation using a yeast and the production of beer or low-malt beer having a rich flavor which comprises, in the case of producing beer or low-malt beer with the use of an early flocculating malt (i.e., a malt having an early flocculating factor of yeast), improving the fermentability of the early flocculating malt. In producing beer or low-malt beer with the use of the early flocculating malt, tannic acid is added to the wort and / or yeast to be used in the fermentation followed by the treatment with the tannic acid to thereby improvethe fermentability of the early flocculating malt. To improve the fermentability of the early flocculating malt in the process of producing beer or low-malt beer, tannic acid is added to the wort before adding the yeast, the fermented wort after adding the yeast or the yeast to be added to the wort and then the treatment is conducted. Preferable examples of the tannic acid to be used in the aboveprocess include gallotannin, tara tannin, gallic acid tannin (hydrolyzed tannin) and persimmon tannin (condensed tannin).

The present invention provides a biologically pure culture of Saccharomyces cerevisiae, which culture has a characteristic nature capable of highly producing lactic acid. A method for preparing the biologically pure culture and a method for production of lactic acid are also provided.

The invention provides a method for preparing biogas and a soil conditioner by utilizing stevia rebaudiana processing waste. The method mainly comprises the following steps: pre-treating waste liquid in the stevia rebaudiana processing process; and then mixing the pre-treated waste liquid and waste residues, and fermenting the mixture in an anaerobic jar. The prepared methane, namely biogas, can be applied to industry or households, and the fermented waste residues are applicable to preparation of soil conditioners. According to the method, in the adopted reacting raw materials, the waste liquid can be waste liquid generated in each procedure in the stevia rebaudiana processing process, and the waste residues can be waste residues generated in each procedure of the stevia rebaudiana processing process. The process of the method is relatively simple and easy to operate, waste resources can be effectively recycled, and energization can be realized.

The invention belongs to the field of food science and technology, and in particular relates to a dietary fiber composition targeting at improving metabolic syndrome, which is prepared by adding appropriate amount of fructan, pectin and cellulose to xylan and mannan The dietary fiber composition comprises the following components: xylan, mannan, fructan, pectin and cellulose, wherein xylan: mannan: fructan: pectin: cellulose The weight ratio is: 5~90:5~90:5~90:0.01~70:0.01~70. The dietary fiber composition prepared by the invention can effectively improve various symptoms of metabolic syndrome and delay the progress of the disease. The dietary fiber composition has a clear mechanism of action and clear disease targets, so when used in human experiments, it shows clear and definite effects in reducing cholesterol, blood sugar, and blood pressure, and the users can obtain clear and significant health benefits. It cannot be realized by previous dietary fiber supplements.

A kind of natural concentrated dietary fiber and preparation method thereof, described natural concentrated dietary fiber is that the pine bark that is rich in dietary fiber is crushed and sieved, soaked in water, drains waste water after soaking, and then transfers the soaked pine bark To the reactor, add water to obtain the pine bark mixed liquid, carry out ultrasonic-assisted enzymolysis treatment, drain the liquid after enzymolysis, then insert the enzymolysis material into Lactobacillus plantarum HKB‑38 for fermentation, and ferment the fermented The material is subjected to high temperature and high pressure heat treatment, cooled and dried to obtain natural concentrated dietary fiber. The invention also includes a preparation method of natural concentrated dietary fiber. The invention selects pine bark with low price and abundant resources as the production raw material, greatly reduces the production cost, makes full use of resources and creates high added value.
