Abstract

The invention discloses transparent phospholipid and a preparation method thereof. After phospholipid and vegetable oil are mixed, a single or combined filter unit of a special filter unit, a gravityfilter, a vacuum filter, a pressure filter and a precision filter is selected, so that the treated phospholipid product is clear and transparent and completely reaches the index of imported phospholipid. The process for producing phospholipid is short in time, high in efficiency, low in cost, safe and reliable in production process and product quality and convenient to popularize.

Description

technical field [0001] The invention relates to the field of oil processing, in particular to a transparent phospholipid and a preparation method thereof. Background technique [0002] Phospholipid is a general term for phospholipid-based lipids, which exist in the cells of all animals and plants, and in plants, they are mainly distributed in seeds, nuts and grains. Phospholipid molecules have hydrophilic and lipophilic properties, making them interfacially active in many applications. In addition to the common functional properties of surfactants, phospholipids also have unique functionality. Phospholipids were first used in the food industry as thickeners for chocolate and confectionary products and emulsifiers / stabilizers for margarine products. The versatility of phospholipids, as well as their "natural" properties make them ideal food additives. [0003] Most of the currently widely used phospholipid preparation processes are extracted from soybean oil, and most of t...
