Abstract: The invention discloses a method for preparing rapeseed oil by a semi-solid aqueous enzymatic process, belonging to the field of functional foods and health care products. The present invention first prepares a semi-solid rapeseed paste with 3.5-4.5% moisture content, which is hydrolyzed by a mixture of pectinase, cellulase and alkaline protease to extract rapeseed oil. The resulting rapeseed oil contains high levels of active ingredients including totaxin, sterol, phenols and beta-carotene. The rapeseed oil of the invention can be added into animal feeds, which helps to reduce animal blood lipid levels and body weight. It can significantly reduce the contents of total triglyceride, total cholesterol and LDC-C in the blood, and, at the same time, increases the level of HDL-C in the blood. In addition, the rapeseed oil prepared by the present invention can relieve hepatic steatosis in hyperlipemia rats.

Abstract: The present invention provides a method for oil extraction from dehydrated Euphausia superbas, which is related to the field of food biotechnology. The method combines a low temperature and low oxygen heat pump dehydration system with a microwave-assisted frozen-blasting dehydration system for Euphausia superba dehydration, resulting in formation of a large number of micro porous structures in dehydrated Euphausia superbas that is good for subsequent oil extraction. The dehydration and extraction process can be separated in the present invention. The low temperature and low oxygen heat pump dehydration system may be installed in shrimp boats to dehydrate Euphausia superbas before transportation so as to increase the effective payloads of shrimp boats. The extraction process of subcritical fluid assisted with ultrasonic operation is carried out under low temperature and low oxygen conditions, therefore the oxidation of active ingredients is avoided to a large extent.

Abstract: Disclosed is a method for reducing the oil content of fried potato chips. According to the method, potatoes are used as raw materials, which are washed, peeled and cut into chips and are subjected to an ion blanching. The potato chips are then coated with a mixed solution of guar gum and sorbitol, and the potato chips are fried after coating. Calcium ions in blanching liquid can chemically react with low-methoxyl pectin contained in the potato chips to form a bridged structure. The calcium ions may also interact with guar gum to facilitate the escape of moisture and reduce the entry of oil during the frying process. Addition of sorbitol can further improve the structure of the coating membrane of guar gum to effectively reduce the oil content without significant influence on the moisture content and other qualities of the final products.
