Description
Deodorized goat/sheep milk, method for producing the same and goat/sheep milk products Technical field The present invention relates to the field of production of milk products.
More specifically, the present invention relates to a deodorized goat/sheep milk, a method for producing the same, and a goat/sheep milk product.
Background art Goat/sheep milk has a high nutritional value, is rich in proteins, fats, minerals, vitamins and various biologically active substances, and has a certain dietetically therapeutic effect and health-care effect. Although goat/sheep milk is favored in many countries around the world, the strong muttony odor of goat/sheep milk is an important factor restricting its popularity in China, affecting the development and utilization of goat/sheep milk products.
Therefore, the technical problem of removing muttony odor of goat/sheep milk must be solved to promote the development in goat/sheep milk industry.
At present, there are many methods for removing muttony odor of goat/sheep milk, such as physical deodorizing process, chemical deodorizing process and biological deodorizing process. However, different deodorizing processes have show specific deficiencies in practical applications.
Physical deodorizing process: at present, a good physical deodorizing method mainly comprises deodorizing goat/sheep milk by using flash evaporation and embedding with ß-cyclodextrin, wherein the underlying mechanism is that the complex in goat/sheep milk is embedded with ß-cyclodextrin, saturated at high pressure, placed into a low-pressure vessel, and subjected to vacuum evaporation and cooling in according to the fact that the boiling point of a solution decreases as the pressure drops, whereby the odor is removed. In addition, in a process of processing of goat/sheep milk IEC180103 English powder, deodorizing can be carried out by steam jetting, and the mechanism thereof is mainly to form vacuum evaporation by continuous decompression, so that the fatty acid in goat/sheep milk is volatilized, thereby reducing the influence of internal chemical components on the goat/sheep milk, and thereby reducing the muttony odor of the goat/sheep milk. The main purpose of physical deodorizing process is to remove medium-chain fatty acids (MCFA) having 8-12 carbon atoms from goat/sheep milk to achieve the deodorizing effect. However, as compared with long-chain fatty acids, MCFA is more easier to be absorbed and has a faster absorption rate, can be rapidly oxidized in vivo to provide energy, and also has the effect of improving lipid metabolism and glucose metabolism. Therefore, the physical deodorizing process will reduce the nutrition of goat/sheep milk to a certain extent, and has high requirements on equipment, large investment, and limited application.
Chemical deodorizing process: chemical deodorizing process mainly comprises adding a small amount of almonds, red dates and orange peel to goat/sheep milk, or directly adding jasmine tea, when goat/sheep milk is cooked, which can effectively remove the muttony odor of goat/sheep milk.
However, the color of the deodorized goat/sheep milk is yellow, and the sensory state such as flavor and taste are slightly changed. The application of the process is limited and cannot be extended to industrial production.
Biological deodorizing process: biological deodorizing process is also a typical process for removing muttony odor from goat/sheep milk, which comprises adding a microorganism such as lactic acid bacteria as a deodorizing agent to the goat/sheep milk, and removing the muttony odor of the goat/sheep milk by the microbial fermentation. This process is often used in the production of cheese, goat/sheep milk wine and goat/sheep milk yogurt, and there is obvious limitation.
It can be seen that the current techniques for removing muttony odor of goat/sheep milk are not mature, and there are still various problems, directly IEC180103 English limiting the development of the goat/sheep milk industry. Therefore, there is a need to provide a new process for removing muttony odor of goat/sheep milk, so that the goat/sheep milk can be better applied in the dairy industry.

Test Example 1 The deodorizing effects of the products obtained in the examples and the comparative examples were tested.
Evaluation criteria: the evaluation team consists of 15 persons who are sensitive to muttony odor of goat/sheep milk. First of all, the samples of the product in each of the examples were heated in a 30°C water bath for 30 IEC180103 English minutes, and then the muttony odor thereof was scored by a 10-point scaling method, wherein 1-3 scores means almost no muttony odor, 3-5 scores means slight muttony odor, 5-7 scores means moderate muttony odor, 7-9 scores means obvious muttony odor, and 9-10 scores means strong muttony odor. A blank control was employed, and 3 parallel tests were carried out for each treatment. X means the score of muttony odor before treatment and y means the score of muttony odor after treatment, and the deodorizing rate = x - y ?100% The deodorizing rates of products obtained in various examples were shown in the following Table 1: Table 1 deodorizing rates of deodorized goat/sheep milks obtained in various examples Sample Deodorizing rate Example 1 58.31 ? 0.10% Example 2 60.25 ? 0.14% Example 3 61.22 ? 0.13% Example 4 62.21 ? 0.18% The above-described examples of the present invention are merely exemplified to clearly illustrate the present invention and not to limit the embodiments of the present invention.
