Embodiment 1

[0028] The edible oil that present embodiment provides is rapeseed oil, and the preparation method of this edible oil is as follows:

[0029] (1) The rapeseed is removed in advance, and the rapeseed with uniform quality is screened for peeling treatment.

[0030] (2) After dehulling treatment, the skin and kernel are separated by the skin and kernel separation system to obtain dehulled rapeseed, and the peeling rate of the dehulled rapeseed is 2%.

[0031] (3) Fry the peeled rapeseed at 110° C. for 20 minutes, and the moisture content after frying is 5%.

[0032] (4) The dehulled rapeseed after frying is sent to a single-screw press for pressing to obtain the above-mentioned edible oil. Among them, before pressing, the single-screw press is preheated to 90°C.

Embodiment 2

[0034] The edible oil that present embodiment provides is camellia oil, and the preparation method of this edible oil is as follows:

[0035] (1) select dehulled camellia oleifera seeds for use, wherein the peeling rate in the dehulled camellia oleifera seeds is 5%.

[0036] (2) The dehulled camellia oleifera seeds were fried at 120° C. for 60 minutes, and the moisture content after frying was 1%.

[0037] (3) The dehulled camellia oleifera seeds after frying are directly sent into a twin-screw press for pressing to obtain crude oil.

[0038] (4) The crude oil is refined according to the existing traditional process to obtain the above-mentioned edible oil.

Embodiment 3

[0040] The edible oil that present embodiment provides is the mixture of okra oil and radish seed oil, and the preparation method of this edible oil is as follows:

[0041] The heated and fried peeled okra seeds and peeled radish seeds are selected as raw materials for pressing, and the moisture content after frying is 3%. The heated and fried peeled okra seeds and peeled radish seeds are directly added to a twin-screw extruder for pressing. Wherein the peeling rate in the mixture of the peeled okra seeds and the peeled radish seeds is 4%.

Abstract

Relating to the field of food processing, the invention provides a peeling hot pressing method and edible oil. The peeling hot pressing method includes pressing of a heated peeled oil crop. Specifically, the heating temperature of the peeled oil crop is 110-130DEG C, the heating time is 20-60min, the water content of per 100 parts of the heated peeled oil crop is less than or equal to 5 parts. By using the peeled oil crop as the raw material, harmful substances in the final product can be reduced. After heat treatment on the peeled oil crop, a series of changes occur in the oil crop, like destruction of oil cells, promotion of protein denaturation, reduction of grease viscosity and the like so as to be suitable for pressing for oil extraction and improvement of oil yield, and the heat treated oil crop can have strong frangrance. The heat treated oil crop can have high oil yield during pressing and has little residue oil. The edible oil prepared by the method has good color and rich fragrance, the product has little residue left, and is easy for preservation.

Description

technical field [0001] The invention relates to the field of food processing, and in particular to a peeling hot pressing method and edible oil. Background technique [0002] In people's daily diet life, edible oil is indispensable, and the edible oil on the market is of a great variety at present, and people also is a headache endlessly to the selection of edible oil. As one of the most important edible oils in the world, rapeseed oil plays an important role in people's life. First of all, the absorption rate of rapeseed oil by the human body reaches 99%, and it has a certain effect of softening blood vessels and anti-aging. Secondly, it contains rich phospholipids, which are very important for the development of nerves and brains. The higher the quality of the oil, the higher its nutritional value and the more demanding the pressing process. Nowadays, many large enterprises or small workshops do not properly control the pressing process. They pay attention to the improve...
