The sesame oil meal extract according to the present disclosure has the effect of inhibiting weight loss, stool abnormalities, rectal bleeding, and a reduction in colon length, and inhibiting the expression of inflammation-mediated cytokines IL-6, IL-1β, and TNF-α, and thus a composition comprising the same as an active ingredient is a composition capable of preventing/improving or treating inflammatory diseases, particularly colitis diseases, and may be usefully used in various industrial fields such as pharmaceuticals or functional health foods.

The present disclosure relates to a process for refining crude oils using a combination of a chemical process and mega-sonic treatment to simultaneously and efficiently separate oil and gum phases. In particular, the present disclosure relates to a process for refining crude oils using a combination of chemical processes followed by megasonic treatment to effectively separate and recover entrained oil from a gum phase to increase the oil yield, and to produce an oil of higher quality with reduced gum content. The present disclosure also relates to a process for refining crude oils using a combination of chemical processes followed by megasonic treatment to effectively separate and recover entrained gums from an oil phase to increase the gum yield, and to produce a gum of higher quality with reduced oil content. The present disclosure also relates to obtaining refined oils and refined gums from the process described herein.

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. Compared with existing methods, the present invention not only possess excellent dehydration efficiency but also uses less time and energy.

A novel method is developed to remove wax and terpene from the wild hemp plants to produce enriched cannabidiol (CBD) crude oil with high quality and further purify the crude oil into crystal/isolate with 99.0% content of CBD. The method utilizes titanium dioxide (TiO.sub.2) photocatalyst for redox reaction under the irradiation of UV (ultraviolet) light in a solvent extraction process of CBD, which significantly removes accompanying wax and terpene. With the beneficial photocatalyst property, the TiO.sub.2 decomposes the wax and terpene in the wild hemp crude extract through appropriate UV radiation to induce catalytic reaction at specific PH (potential hydrogen) levels. Through optimizing the photocatalyst dewaxing using TiO.sub.2, the method achieves the best dewaxing effect and maximum terpene reduction. Thus, the method offers a low-cost, reusable, and biologically friendly process of removing wax and terpene to maximize the efficiency and effectiveness of the separation processes in the CBD production.
