Problems solved by technology

Camellia oil is relatively stable at room temperature. Experiments have shown that adding tea oil to other vegetable oils such as sunflower oil can significantly increase its shelf life. However, since tea oil is in a liquid state, it brings many difficulties to storage, transportation and processing. Application and development are limited to some extent

Embodiment 1

[0012] Embodiment 1: the method for preparing microcapsules by compounding camellia oleifera seed oil and linseed oil as the core material according to the present invention, the specific steps are as follows:

[0013] (1) The wall material is soybean protein isolate and maltodextrin mixed in a ratio of 1:2 to 1:0.5;

[0014] (2) The core material is a mixture of camellia oil and linseed oil in a ratio of 1:1 to 10:1;

[0015] (3) The ratio of core material to wall material is 1:2~1:0.5;

[0016] (4) The emulsifier is a mixture of sucrose fatty acid ester and glyceryl stearate in a ratio of 1:1 to 8:1;

[0017] (5) The solid-to-liquid ratio is 10% to 30%.

[0018] Weigh an appropriate amount of the above-mentioned wall material. The ratio of soybean protein isolate and maltodextrin in the wall material is 1:2. After mixing, add distilled water and stir to mix and dissolve. Slowly add a certain amount of emulsifier and core material. The sucrose fat in the emulsifier The rat...

Embodiment 2

[0021] Example 2: The difference from Example 1 is that the ratio of soybean protein isolate and maltodextrin in the wall material is 1:1.5, the ratio of camellia seed oil and linseed oil in the core material is 1:1, and the emulsifier The ratio of sucrose fatty acid ester to glyceryl stearate is 1:1, and the concentration of the emulsion is 15%.

Embodiment 3

[0022] Example 3: The difference from Example 1 is that the ratio of soybean protein isolate and maltodextrin in the wall material is 1:1, the ratio of camellia oil and linseed oil in the core material is 5:1, and the emulsifier The ratio of sucrose fatty acid ester to glyceryl stearate is 2:1, and the concentration of the emulsion is 20%.

Abstract

The invention relates to a preparation method of camellia oleosa seed oil and linseed oil compound microcapsules. Two oils, namely camellia oleosa seed oil and linseed oil, are compounded in appropriate proportion as a core material. The preparation method comprises the following steps of: (1) weighing a wall material, adding distilled water, stirring, mixing and dissolving, and slowly adding an emulsifier and the core material; (2) stirring and emulsifying the mixed solution for 20 minutes at the temperature of 80 DEG C; (3) homogenizing the emulsion for twice at 40Mpa by adopting a high-pressure homogenizer, and naturally placing and cooling; and (4) carrying out spray drying on the emulsion to obtain the camellia oleosa seed oil and linseed oil compound microcapsules. The preparation method provided by the invention is simple and practicable, inherent nutritional ingredients of tea oil are kept, linolenic acid content is also increased, a fatty acid structure of oil can more meet body need, and oil property is more stable and difficult to be oxidized, a development and utilization approach of camellia oleosa seed oil and linseed oil is broadened, and good technical support is provided for deep processing utilization of camellia oleosa seed oil.

Description

technical field [0001] The invention relates to the field of deep processing of camellia oil, in particular to a preparation method of camellia oleifera seed oil and linseed oil compound microcapsules. Background technique [0002] Camellia oleifera seed oil is rich in nutrition. It is the only special oil with high oleic acid content comparable to western olive oil in my country. It is known as "the first oil in the East" and "olive oil in the East". 93%, including 83% oleic acid, 10% linoleic acid), camellia glycosides, phospholipids and saponins, vitamin E, carotene and other antioxidants, which are close to or even exceed olive oil in various main indicators, and are considered to be " Vegetable oil of the highest quality". In addition to food, camellia oil is also an important chemical and pharmaceutical raw material. It has broad application prospects in food, industry, medicine, cosmetics and other industries. In recent years, the demand for camellia oleifera seed oi...
