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

preparation example Construction

[0028] A preparation method of passion fruit seed oil, comprising the steps of:

[0029] (1) Crushing: Freshly picked passion fruit with no damage on the outside is used as raw material, and passion fruit seeds are obtained after separation and drying. The weight water content of raw passion fruit seeds is 1.50-3.00%, and the total sugar content is 1.16-2.24g / 100g. Fat content 21.00-25.30g / 100g, protein content 10.10-11.60g / 100g, linoleic acid content 15.00-16.50g / 100g, oleic acid content 2.80-3.70g / 100g, total phenol content 6.50-7.80g / 100g. Passion fruit seed powder is obtained after crushing and sieving (the sieve is 20-40 mesh);

[0030] (2) Raw material pretreatment: steam the passion fruit seed powder at 120°C for 5-10 minutes, and the tile thickness is less than 1cm;

[0031] (3) Enzymolysis: add an appropriate amount of distilled water to the pretreated passion fruit seed powder to make a homogenate, and enzymolyze it for a certain period of time under the action of a...

Embodiment 1

[0051] A preparation method of passion fruit seed oil, comprising the steps of:

[0052] (1) Crushing: Freshly picked passion fruit with no damage on the outside is used as raw material. The raw material comes from Guangxi Guiping Huixin Passion Fruit Planting Cooperative. Passion fruit seeds are obtained after separation and drying. The weight water content of raw passion fruit seeds is 1.80%, the total sugar content is 1.16g / 100g, the fat content is 22.80g / 100g, the protein content is 11.40g / 100g, the linoleic acid content is 15.50g / 100g, and the oleic acid content is 3.70g / 100g , with a total phenol content of 7.40g / 100g, which was crushed and sieved (with a screen of 20 meshes) to obtain passion fruit seed powder;

[0053] (2) Raw material pretreatment: Weigh 100g of crushed passion fruit seed powder, steam treat the passion fruit seed powder at 120°C for 5 minutes, and spread it with a thickness of less than 1cm;

[0054] (3) Enzymolysis: add an appropriate amount of dis...

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...
