Problems solved by technology

The winterization method is simple and can remove grease precipitation to a certain extent, but the removal effect is limited. After one to two months, the grease will precipitate again or appear turbid, and the winterization time is relatively long, which affects production efficiency ; and although the effect of hydration degumming is relatively good, it will cause obvious changes in the taste of vegetable oils, and increase the trichloropropanol ester in the oils, and will also destroy some natural active ingredients in the oils

Abstract

Belonging to the technical field of vegetable oil processing, the invention relates to a method for removal of vegetable oil precipitate after pressing. The method includes: subjecting pressed vegetable oil to coarse filtration, then adding a nonionic surfactant for microwave radiation treatment, conducting cooling and filtering, and removing precipitate. The vegetable oil obtained by the method provided by the invention has good quality, and is free of precipitate or turbid phenomenon after placement at 0-6DEG C for 1-3 months.

Description

technical field [0001] The invention relates to a method for removing precipitation of vegetable oil after machine pressing, and belongs to the technical field of vegetable oil processing. Background technique [0002] In recent years, in the field of edible oil, more and more consumers have a soft spot for edible oil produced by cold pressing process. The reasons are as follows: first, the process is safe, using low-temperature cold pressing technology, without high-temperature refining; second, the taste is good, the taste of cooking is pure, and the aroma is strong; third, it is rich in nutrition, and the natural and effective active ingredients of vegetable oil are retained to the greatest extent. [0003] However, natural vegetable oils generally contain waxes and certain colloidal substances, which are easy to crystallize and precipitate during storage, making the oil turbid and affecting the appearance quality. In order to keep the oil clear and transparent at low te...
