Embodiment 1

[0032] Determination of Embodiment 1 Freeze Pulverization Degree

[0033] The supercritical extraction conditions are 100g of material, extraction pressure of 30MPa, extraction temperature of 45°C, CO 2 The flow rate was 25L / h, the extraction time was 60min, the separation pressure was 7MPa, and the separation temperature was 35°C. The effects of different crushing degrees (20 mesh, 40 mesh, and 60 mesh) on the oil yield of blackberry seeds were investigated respectively. The oil yield of blackberry seeds showed a gradual increase trend. However, it was found in the experiment that if the crushing degree is greater than 60 mesh, the too fine material will 2 The fluid enters the pipeline through the filter screen and causes pipe blockage, which is not conducive to the use and maintenance of the instrument. Considering comprehensively, the crushing degree of blackberry seeds is preferably 40-60 mesh, and 60 mesh is the best.

Embodiment 2

[0034] The determination of embodiment 2 vacuum freeze-drying degree

[0035] The supercritical extraction conditions are 100g of material, extraction pressure of 30MPa, extraction temperature of 45°C, CO 2 The flow rate is 25L / h, the extraction time is 60min, the separation pressure is 7MPa, and the separation temperature is 35°C. The effects of different water contents (1.17%, 3.43%, 5.35%, and 8.54%) on the oil yield of blackberry seeds are respectively investigated. It can be seen from the results When the water content of blackberry seeds was in the range of 1.17%-8.54%, the oil yield of blackberry seed oil increased first and then decreased. When the water content was 3.43%-5.35%, the oil yield was significantly higher than that of other water contents (p< 0.05). And when the moisture content of blackberry seeds is too high, the phenomenon of "ice blockage" is prone to occur, and the extracted oil is turbid and darkened in color. Therefore, the water content of blackbe...

Embodiment 3

[0036] The determination of embodiment 3 supercritical extraction conditions

[0037] Oil yield is the evaluation of supercritical CO 2 An important indicator of the efficiency of extracting blackberry seed oil, and the extraction pressure, extraction temperature, CO 2 The flow rate is affected by the supercritical CO 2 Significant conditions for oil yield in extraction of blackberry seed oil. Therefore the present invention selects extraction pressure, extraction temperature, CO 2 The three flow factors are the independent variables of the Box-Behnken design, and the oil yield rate of blackberry seed oil is used as the response value. Design expert 8 data processing software is used for response surface analysis to optimize the extraction conditions. The experimental design results of the response surface optimization experiments are shown in Table 2.

Abstract

The present invention belongs to the field of food processing, and discloses a blackberry seed oil microcapsule and a preparation method thereof. The preparation method for the blackberry seed oil microcapsule comprises the following steps: (1) carrying out freezing crushing on blackberry seeds; (2) carrying out vacuum freeze-drying on the blackberry seeds; (3) carrying out supercritical CO2 extraction to obtain a blackberry seed oil; and (4) preparing the blackberry seed oil microcapsule. With the present invention, advanced technologies of freezing crushing, vacuum freeze-drying, supercritical CO2 extraction and microencapsulation are combined and applied in the blackberry seed oil processing technology, and the temperature is always maintained at a low level during the whole blackberry seed oil extraction process, such that grease is not easily subjected to oxidative deterioration, functional active ingredients in the blackberry seed oil are substantially maintained, and the oil extraction rate is 18.6%; the blackberry seed oil microcapsule prepared by spray drying has advantages of long shelf life, easy storage and easy transportation, and the encapsulation rate of the microcapsule is up to more than 95%; and the blackberry seed oil microcapsule can be applied in food and health care products.

Description

technical field [0001] The invention belongs to the field of food processing, and relates to a blackberry seed oil microcapsule and a preparation method thereof. Background technique [0002] Blackberry is a perennial vine of Rubus genus in the family Rosaceae. Because its fruit is rich in a variety of functional components and has high economic value, it is known as the "golden fruit" in the world. my country is the main area for growing blackberries in Asia. Blackberry fresh fruit is a typical processed fruit, but during its processing, its seeds have not been effectively developed and utilized as a by-product, and are only treated as garbage, which not only causes waste of resources, but also causes serious pollution to the environment. [0003] The content of unsaturated fatty acids in blackberry seed oil is relatively high, and its main fatty acid components and contents are: linoleic acid 61.22%, linolenic acid 17.60%, oleic acid 14.72%, palmitic acid 3.71%, stearic a...
