A method for lignocellulose conversion to sugar with improvements in yield and rate of sugar production has been developed by using ionic liquid pretreatment. This new pretreatment strategy substantially improves the efficiency (in terms of yield and reaction rates) of saccharification of lignocellulosic biomass. Cellulose and hemicellulose, when hydrolyzed into their sugars, can be converted into ethanol fuel through well established fermentation technologies. These sugars also form the feedstocks for production of variety of chemicals and polymers. The complex structure of biomass requires proper pretreatment to enable efficient saccharification of cellulose and hemicellulose components to their constituent sugars. Current pretreatment approaches suffer from slow reaction rates of cellulose hydrolysis (by using the enzyme cellulase) and low yields.

A process for manufacturing xylose by extracting hemicellulose from a cellulosic material, such as by a cold caustic extraction method, concentrating the extract, such as by nanofiltration, into a hemicaustic stream containing hemicellulose with greater than about 85 wt % xylan content, and subsequently hydrolysing the xylan from the hemicaustic stream to xylose. The high concentration of xylan within the concentrated hemicaustic stream enables hydrolyzation of the xylan to food-grade xylose and, optionally, hydrogenation of the xylose to xylitol without the need of a chromatographic separation step as previously required.

The invention provides a drink and a sauce having rich nutrients and multiple health-care functions, which are prepared by leaching fermented soybeans with added vinegar (wine, fruit juice, water or tear), deep processing and adding raw sugar and other auxiliaries containing rich nutrients and bioactivators. Soybeans undergo germination, fermentation and other extremely complex biochemical processes to form hundreds of nutrients and activators with the nutrients of the soybeans. A large number of Chinese and foreign documents prove that the substances have health care functions such as human body free radical clearing, arteries hardening prevention, immunity improvement, cancer resistance, blood fat and cholesterol reduction, blood pressure reduction, blood sugar reduction, bowel loosening for relieving constipation, intestinal microecology improvement, beneficial bacteria propagation and bacterium resistance and suppression. The invention aims to solve a technical problem that the nutrients were not fully used by Chinese people in the past 2,000 due to high salinity (such as that of lobster sauce, soybean paste, preserved bean curd and soy sauce) and disagreeable flavor (such as that of natto and tempe). The invention provides a novel drink and a novel sauce which contain nutrients and bioactivators of fermenting soybeans, are edible and contribute to absorption. Till now, no records of the uses of the soybean food have been found in Chinese and foreign documents. The drink and the sauce fill the gap of health care products in China, are expected to contribute to the promotion of the health care cause in China.
