Description

High-calcium crystal ball, preparation method thereof and normal-temperature yoghourt with high-calcium crystal ball
Technical Field
The invention belongs to the technical field of high-calcium yogurt, and particularly relates to a high-calcium crystal ball, a preparation method thereof and high-calcium crystal ball normal-temperature yogurt.
Background
Calcium is used as a necessary macroelement of human body, plays a very important role in each stage of growth and development, and the demand of people in different stages for calcium is also different. For example, school-age children and adolescents develop rapidly, height and bone density grow rapidly, and calcium demand is high. The pregnant women, the fetus will develop to extract some calcium from the mother, so the need for calcium is larger than that of the general population. In addition, as people age, their body functions change, various hormones are secreted less, and the problem of calcium loss is increasingly aggravated, so that the people over 50 years old need to increase the intake of calcium appropriately. The report of nutrition and chronic disease status of Chinese residents (2015) shows that the problem of calcium deficiency of residents still exists. Thus, balancing diet, ensuring adequate calcium intake is a current social health problem that is urgently addressed.
In the 70 s of the 20 th century, the japanese ministry of thick life was first put forward the concept of "functional food" and then introduced into the european food sciences. Today, the concept of functional foods is increasingly accepted by consumers worldwide. In China, with the improvement of the knowledge level of people, the relationship between functional foods and health is also becoming more and more accepted. In view of the existing functional products on the market, the most common is calcium reinforcement and various vitamins, and the relationship between calcium supplement and physical health is well known to consumers.
The dairy product is rich in nutrition, is an optimal food carrier for natural milk calcium, and is easy to obtain in daily life. The yoghurt is a product prepared by taking fresh cow and sheep milk or milk powder as a raw material and fermenting the raw material by lactic acid bacteria. Compared with fresh milk, the yoghurt contains a large amount of lactic acid bacteria beneficial to human health, and nutrients in milk components are thinned through fermentation, so that the yoghurt is more beneficial to human absorption. Therefore, the method for enhancing the quality of national health by enhancing the calcium through the yoghurt product is an economic and convenient way.
The existing high-calcium dairy products on the market at present mainly improve the calcium content in two ways: (1) The whole calcium content ratio is improved by concentrating the raw milk; (2) adding exogenous calcium directly to the product. But all have the following problems:
(1) The method of concentrating raw milk can promote the content of all components in the milk except water, the cost of the product produced by the process is higher, and the difference between the taste and the product prepared from common raw milk is large, so that the product is not suitable for being used as a conventional product.
(2) By directly adding exogenous calcium to the product: the types of exogenous calcium are largely classified into soluble ionic calcium and insoluble or slightly soluble molecular calcium. Casein in milk is relatively sensitive to calcium ions, and ionic calcium can cause casein to flocculate. Particularly in yoghurt, as the pH value is reduced, calcium element existing in the form of stable calcium phosphate in a milk system is dissociated into calcium ions and is enriched to act with casein, so that casein is flocculated, and the product quality is affected; the molecular calcium has low solubility, and after the addition amount is too high, obvious granular feel and precipitation phenomenon can be generated, so that the two calcium sources cannot be directly added into the yoghurt in a relatively large amount.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides the high-calcium crystal ball, the preparation method thereof and the normal-temperature yoghurt with the high-calcium crystal ball, which have high calcium content, smooth and fine texture and no granular feel and can complement the shortage of daily calcium intake of consumers.
In order to achieve the above purpose, the technical scheme adopted by the invention for solving the technical problems is as follows: providing a high-calcium crystal ball, which consists of a crystal ball colloid and a fixing liquid, wherein the mass ratio of the crystal ball colloid to the fixing liquid is 1:10-20;
The crystal ball colloid comprises the following raw materials in parts by weight: based on 1000 parts, 10-100 parts of calcium salt, 5-100 parts of sweetener I, 0.1-10 parts of colloid and the balance of RO water;

Further, the strain is a bacterial agent formed by mixing commercial streptococcus thermophilus and lactobacillus bulgaricus according to the mass ratio of 1:1.
In summary, the invention has the following advantages:
1. Compared with the existing market products, the invention avoids the phenomenon that calcium salt is directly added into the yoghurt and reacts with substances in the yoghurt to influence the quality of the yoghurt. The granular substances with chewing feeling such as crystal balls are added into the yoghurt product, so that the interestingness and edibility of the product are enhanced. The crystal ball is embedded with calcium salt, so that the addition amount of the calcium can be greatly increased, the upper limit (1000 mg/kg) of the national standard calcium serving as a nutrition enhancer is reached, and the normal-temperature yoghurt calcium enhancement amount of the high-calcium crystal ball is positioned in the front of the calcium supplementing products in the existing market.
2. In addition, the existing explosion beads and the existing electric-shock-resistant products on the market are not found to be added with calcium serving as a nutrition enhancer, and most of the products cannot be subjected to high-temperature heating or strong mechanical treatment, so that the application is limited. The crystal ball provided by the invention has the advantages that different colloid materials are selected as the wall materials, the crystal ball can resist high-temperature sterilization, and the taste of the crystal ball is not greatly changed even after high-temperature treatment, so that the crystal ball can be applied to normal-temperature products. After a period of shelf life observation experiments, the crystal balls are soaked in the yoghurt without causing the change of the yoghurt base stock.
3. The preparation method can embed the crystal ball formula of the calcium salt, and the gel is formed by adopting the combined action of calcium ions, potassium ions and low temperature.
4. The invention provides a crystal ball formula capable of tolerating high temperature treatment, wherein part of components in the formula have the characteristic of high gel strength, and the taste of the prepared crystal ball is not changed after the high temperature treatment.
