Embodiment 1

[0030] The white sesame is cleaned, and the impurity content of the cleaned sesame is reduced to below 0.5%. The cleaned sesame is peeled, and the peeling is carried out with a water washing and peeling machine. The sesame is soaked and stirred with sodium hydroxide with a mass concentration of 3%, and the sesame skin is removed. The peeling rate is 90%, and the peeled sesame is dried. .

[0031] Put the peeled sesame seeds into the ZX10 screw oil press for pressing, the pressing temperature is controlled below 70°C, and the residual oil content of the sesame cake after pressing is controlled at 16%.

[0032] In the extraction tank, use liquefied butane to extract the sesame low-temperature pressed cake three times. The extraction pressure is: 0.6Mpa, the extraction temperature is controlled at 40°C, the residual oil is reduced to 1%, and then the liquefied butane is volatilized under reduced pressure to obtain a low temperature Sesame meal.

[0033] In the extraction tank, ...

Embodiment 2

[0035] The sesame is cleaned, and the impurity content of the cleaned sesame is reduced to below 0.5%. The cleaned sesame is peeled, the peeling rate is 85%, and the peeled sesame is dried.

[0036] The dehulled sesame is pressed, and the pressing temperature is controlled below 70°C, and the residual oil content of the sesame cake after pressing is controlled at 20%.

[0037] Use propane to extract the sesame low-temperature pressed cake three times, the extraction pressure is 1.6Mpa, the extraction temperature is controlled at 50°C, the residual oil is reduced to 1%, and then the propane is volatilized under reduced pressure to obtain low-temperature sesame meal.

[0038] The low-temperature sesame meal was extracted with acetone, the extraction temperature was controlled at 50°C, the solid part and the extract were separated, and the acetone was removed from the solid part to obtain sesame protein powder with a protein content of 70%.

[0039] The equipment used and the un...

Embodiment 3

[0041] The sesame is cleaned, and the impurity content of the cleaned sesame is reduced to below 0.5%. Peel the cleaned sesame seeds: dry the raw sesame seeds with a water content of 10% at 55°C until the water content is 7%; cool the dried sesame seeds to 35°C and let them stand for 10 minutes; finally, transfer the sesame seeds to Peeling and separation are carried out in the peeling separator, the peeling rate is 85%, and the peeled sesame is dried.

[0042] Press the peeled sesame seeds, the pressing temperature is controlled below 70°C, and the residual oil content of the sesame cake after pressing is controlled at 10%.

[0043] Use propane and liquefied butane (volume ratio 1:1) to extract sesame low-temperature pressed cake three times, the extraction pressure is 1.0Mpa, the extraction temperature is controlled at 30°C, the residual oil is reduced to 1%, and then the propane and Liquefied butane to obtain low-temperature sesame meal.

[0044] The low-temperature sesam...

Abstract

The invention belongs to the technical field of preparing by-product from oil materials, and specifically, relates to a production technology of sesame protein powder. The production technology adopts sesame as a raw material and comprises the following steps: (1) cleaning and peeling sesame; (2) carrying out low-temperature squeezing of the peeled sesame obtained from step (1) at a temperature of room temperature to 70 DEG C; (3) carrying out extraction deoiling of sesame cakes obtained by the low-temperature squeezing; and (4) carrying out desugaring of the sesame cakes obtained by the step(3). The sesame protein powder prepared by the production technology has the advantages of high product additional values, high purity, and low denaturation rate. The production technology can be widely used in the fields of medicines, foods, feed, chemical industry and the like.

Description

technical field [0001] The invention belongs to the technical field of by-products of oil processing, in particular to a production process of sesame protein powder. Background technique [0002] Sesame is a crop variety with rich nutritional value, which has long attracted the attention of consumers. Usually the processing of sesame is mainly based on the production of sesame oil. During the production process of sesame oil, the method of frying seeds at high temperature is often used, and the obtained sesame oil has a strong fragrance and is very popular among consumers. However, high-temperature heating will denature and destroy the solid protein in sesame, so all sesame cakes produced at high temperature can only be used as raw materials or fertilizers for feed, and their utilization value is greatly reduced. Therefore, how to make sesame protein products while extracting oil in the sesame processing process has always been a concern in this field. Contents of the inv...
