Passion fruit seed oil and preparation method thereof

Abstract

The invention belongs to the technical field of edible vegetable oil processing and extraction, and particularly relates to passion fruit seed oil and a preparation method thereof, wherein the preparation method comprises the following steps: (1) crushing; (2) pretreating raw materials; (3) performing enzymolysis; (4) performing enzyme deactivation treatment; (5) performing demulsification; (6) performing centrifugal separation; and (7) obtaining a finished product. According to the method, an aqueous enzymatic extraction process is adopted, no additives and solvent residues are left except for food enzymes, the treatment temperature and time are strictly controlled in the processing process, and it is guaranteed that natural effective components in the passion fruit seeds are reserved. Meanwhile, the raw materials are pretreated after being crushed, the oil extraction rate is increased to the maximum extent by means of demulsification after enzymolysis, and the problem that the oil extraction rate is low due to the fact that water-oil emulsions are difficult to separate is effectively solved. The passion fruit seed oil prepared by the method is clear, transparent and bright in color and luster, has sour and sweet fruit fragrance, is mild in texture, not greasy, free of irritation, good in quality, safe and stable, and nutrient substances such as linoleic acid, oleic acid and polyphenol are well reserved.

Description

technical field [0001] The invention belongs to the technical field of edible vegetable oil processing and extraction, and in particular relates to a passion fruit seed oil and a preparation method thereof. Background technique [0002] Passion fruit, also known as egg fruit and passion fruit, belongs to the genus Passiflora (Passion fruit granadilla). At the beginning of the 20th century, China began to introduce purple passion fruit from Tokyo, Japan, and now it is cultivated in Fujian, Guangxi, Guangdong, Hainan, Taiwan, Sichuan and other places. It is known as the "king of juice" because it contains the aroma of 160 kinds of fruits such as strawberry, apple, mango, banana and pineapple. Passion fruit contains 55% peel, 34% juice and 11% seeds. Along with the rapid development of the passion fruit planting industry, in order to increase its economic value, the passion fruit processing industry is also growing. On the market, passion fruit is mainly used to make concent...

Problems solved by technology

[0005] The object of the present invention is to provide a kind of passion fruit seed oil and its preparation method in view of the existing problems such as single extraction process of passion fruit seed oil, insufficient flavor, low efficiency and poor stability of extracting fruit oil by aqueous enzymatic method

At the same time, after the raw material is crushed, it is pretreated first, so that different components in the raw material tissue can better interact with the complex enzyme; after enzymatic hydrolysis, the method of demulsification effectively overcomes the difficulty of separating the water-oil emulsion and the low oil yield. problem, to maximize the oil yield
