Description

Chia seed plant-based yoghurt block and preparation method thereof
Technical Field
The invention relates to chia seed plant based yoghurt block and a preparation method thereof, belonging to the technical field of dairy product preparation.
Background
Chia seed is seed of chia (Silva hispanica L.), has edible history of about five thousand years, is rich in nutrition, and is known as "super food". Chia seeds, which contain 15% -25% protein, 26% -41% carbohydrate and 30% -33% fat, have a polyunsaturated fatty acid content of up to 80% -86% and a ratio of polyunsaturated fatty acids in the omega-6: omega-3 series of about 1:3, are also the highest natural food known to contain alpha-linolenic acid. In addition, the mass fraction of the dietary fiber of chia seeds is 26-35%, which is 3, 9 and 12 times of that of oat, corn and wheat respectively. In 2014, the Qiya seeds are officially approved as new food raw materials in China, which marks that the Qiya seeds have legal status in the application of the Qiya seeds in the food industry in China.
The chia seed can be directly eaten, and can be added into food such as beverage, cookies, bread, yogurt, vegetable salad, etc. to improve its nutritive value. However, once the integrity of chia seeds is destroyed, part of the nutrients, especially omega-3 fatty acids, are lost, and how to fully exert the nutritional and functional properties of chia seeds without destroying the integrity of chia seeds becomes a big problem for the products on the market at present. Patent with application number CN202110610518.7 discloses a chia seed sandwich pearl and a preparation method thereof, wherein the outer skin of the chia seed sandwich pearl is made of cassava starch, water, white granulated sugar and seasonings, the inner core of the chia seed sandwich pearl is made of chia seed, cassava starch, water and white granulated sugar, the chia seed sandwich pearl has the taste similar to that of a sesame sandwich pearl, the peculiar fragrance of chia seed is added, the originality is very ingenious, but the chia seed amount is less, and the nutrient components of chia seed cannot be effectively utilized. The patent with the application number of CN201910144041.0 discloses a preparation method of chia seed oil soft sweets, the soft sweets are prepared from fine granulated sugar, maltose, syrup, lemon juice and chia seed oil, the soft sweets are convenient to carry and are popular among teenagers and children, but greasy taste can be generated due to the fact that the additive amount of chia seed oil is high.
The yoghourt is a popular fermented dairy product, has unique flavor and rich nutrition, and contains active lactic acid bacteria with health care function. However, the transportation and storage of the live bacteria yoghourt require low-temperature conditions, and the shelf life is short. The freeze-dried food can be stored for a long time without adding preservatives, and can retain the original color, fragrance, taste and nutritional ingredients. The freeze drying technology is applied to the field of the yoghourt, the activity states of components such as protein, lipid and the like in the yoghourt can be effectively maintained, the original quality and the health care value of the yoghourt are kept to the maximum extent, and the yoghourt can be transported and stored at normal temperature, has longer quality guarantee period and has good development prospect. The animal basic milk block prepared by the freeze drying technology is the most common preparation technology in the market at present, but the animal basic milk has the problems of thick and greasy taste, single level and incomplete nutrition, and needs to be improved in the aspects of taste and nutrition.
