Problems solved by technology

However, some studies have shown that microwave treatment of sesame will increase the acid value of sesame oil (The effect of microwave drying on the quality characteristics of sesame, 2016)
This limits the application of microwave technology in the production of sesame oil

Embodiment 1

[0052] Clean the sesame seeds to remove impurities, and then wash with water to remove silt and shriveled particles. Spread the washed sesame seeds on the sieve until there is no more water dripping, and bake at 210°C for about 20 minutes. Add 40% water by weight to the fried sesame seeds, and the water temperature is 30°C. And stirred for 15min and left for 2h.

[0053] Microwave treatment is carried out on the sesame after adding water, the material layer thickness is 5cm, the conditions are: 7KW, time 5min, transmission speed 30cm / min.

[0054] Oil was pressed by a screw press, and the crude oil was left to stand at 4°C for 3 days and filtered under normal pressure to obtain samples. Then evaluate the flavor and determine the acid value, wherein the acid value results are shown in Table 1, and the flavor evaluation results are shown in Table 2.

Embodiment 2

[0056] Clean the sesame seeds to remove impurities, and then wash with water to remove silt and shriveled particles. Spread the washed sesame seeds on the sieve until there is no more water dripping, then bake and fry at 230°C for about 15 minutes. Add 55% water by weight to the fried sesame seeds, and the water temperature is 50°C. And stirred for 10min and left for 1h.

[0057] Microwave treatment is carried out on the sesame after adding water, the material layer thickness is 1.5cm, the conditions are: 3KW, time 3min, transmission speed 90cm / min. Oil was pressed by a screw press, and the crude oil was left to stand at 4°C for 3 days and filtered under normal pressure to obtain samples. Then evaluate the flavor and determine the acid value, wherein the acid value results are shown in Table 1, and the flavor evaluation results are shown in Table 2.

Embodiment 3

[0059] Clean the sesame seeds to remove impurities, and then wash with water to remove silt and shriveled particles. Spread the washed sesame seeds on the sieve until there is no more water dripping, and bake at 190°C for about 25 minutes. Add 70% water by weight to the fried sesame seeds, and the water temperature is 90°C. And stirred for 25min and left for 3h.

[0060] Microwave treatment is carried out on the sesame after adding water, the material layer thickness is 3cm, the conditions are: 5KW, time 6min, transmission speed 60cm / min. Use a hydraulic oil press to extract the oil, and the crude oil is allowed to stand at 4°C for 3 days and filtered under normal pressure to obtain the sample. Then evaluate the flavor and determine the acid value, wherein the acid value results are shown in Table 1, and the flavor evaluation results are shown in Table 2.

Abstract

The invention provides a method for preparing sesame oil. The method provided by the invention comprises the following steps: A) adding water into baked and stir-fried sesame to obtain a wet sesame material; and B) heating the wet sesame material obtained in the step A. According to the ground sesameseed oil prepared by adopting the method disclosed by the invention, the acid value of the sesame oil can be reduced, the use amount of the sesame oil can be reduced when the sesame oil is mixed with cold dishes, and meanwhile, the obvious flavor characteristics of the ground sesameseed oil are achieved.

Description

technical field [0001] The invention belongs to the technical field of oils and fats, and in particular relates to a machine-pressed small-ground sesame oil and a preparation method thereof. Background technique [0002] Small grinding sesame oil is a kind of edible oil with a long history in our country. It is very popular among ordinary people because of its rich and full aroma. The traditional small-milled sesame oil is prepared by the method of substituting water, which mainly includes the following steps: cleaning, washing with water, frying seeds, raising smoke, grinding sauce, blending pulp and stirring oil, shaking oil and other steps. However, this process is labor-intensive, and continuous production has not yet been realized, and the production scale is greatly limited. In addition, this process generally has the problem that hygienic conditions are difficult to guarantee. [0003] Regarding the improvement of the preparation method of small ground sesame oil, t...
