Description

High-calcium crystal ball, preparation method thereof and high-calcium crystal ball normal-temperature yoghourt
Technical Field
The invention belongs to the technical field of high-calcium yoghourt, and particularly relates to a high-calcium crystal ball, a preparation method thereof and high-calcium crystal ball normal-temperature yoghourt.
Background
Calcium, as a major element essential to the human body, plays a very important role in all stages of growth and development, and the demand of calcium for people in different periods also varies. For example, the growth and development of the school-age children and adolescent children are rapid, the height and bone density are increased rapidly, and the demand for calcium is high. In pregnant women, the fetal development draws a portion of the calcium from the mother and therefore the calcium demand is greater than that of the general population. In addition, as people age, physical functions are changed, secretion of various hormones is reduced, the problem of calcium loss is increased, and people over 50 years old need to increase the calcium intake properly. Chinese resident nutritional and chronic disease condition reports (2015) show that the problem of calcium deficiency still exists. Therefore, balancing the diet, ensuring adequate calcium intake is an urgent social health problem to be solved at present.
In the 70 s of the 20 th century, the concept of "functional food" was first proposed by the japan's ministry of health, and then introduced into the european food science community. Today, the concept of functional food is increasingly being accepted by consumers worldwide. In China, with the improvement of the knowledge level of people, the relationship between functional food and health is more and more approved. In spite of the existing functional products on the market, the most common product is to strengthen calcium and various vitamins, which shows that the relationship between calcium supplement and body health is well known by consumers.
The dairy product is rich in nutrition, is the best food carrier of natural milk calcium, and is easy to obtain in daily life. The yoghourt is a product prepared by fermenting fresh cow and sheep milk or milk powder serving as a raw material by using lactic acid bacteria. Compared with fresh milk, the yoghourt contains a large amount of lactic acid bacteria beneficial to human health, and nutrient substances in the milk components are refined through fermentation, so that the yoghourt is more beneficial to human absorption. Therefore, the method for enhancing the national health quality by the yoghourt product is an economic and convenient mode.
The existing high-calcium dairy product on the market at present mainly improves the calcium content through two ways: (1) the whole proportion of calcium content is improved by concentrating the raw milk; (2) exogenous calcium was added directly to the product. However, the following problems are present:
(1) the raw milk is concentrated, so that the content of all components in the cow milk except water is increased, the product produced by the process has higher cost, the taste is greatly different from that of the product prepared from the common raw milk, and the cow milk is not suitable for being used as a conventional product.
(2) By means of direct addition of exogenous calcium to the product: the types of exogenous calcium are mainly classified into soluble ionic calcium and insoluble or slightly soluble molecular calcium. Casein in milk is sensitive to calcium ions, which can cause casein flocculation. Particularly in the yoghourt, as the pH value is reduced, calcium element existing in a stable calcium phosphate form in a milk system is dissociated into calcium ions, and the calcium ions are enriched to have the action with casein, so that the casein is flocculated to influence the product quality; molecular calcium has low solubility, and obvious granular feeling and precipitation phenomena can be generated after the addition amount is too high, so that the two calcium sources cannot be directly added into the yoghourt in a 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 high-calcium crystal ball normal-temperature yoghourt, which have high calcium content, smooth and fine texture and no granular sensation and can supplement the deficiency of daily calcium intake of consumers.
In order to achieve the 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 stationary liquid, wherein the mass ratio of the crystal ball colloid to the stationary liquid is 1: 10-20;

Further, the viscosity of the crystal ball colloid was 2000-6000 mPas.
Further, the viscosity of the crystal ball colloid is 3000-5000 mPas.
This is because too high viscosity may result in uncontrollable shape when the pellet is dropped into the fixing liquid, and too low viscosity may result in scattering of the pellet when the pellet is dropped into the fixing liquid.
The preparation method of the high-calcium crystal ball comprises the following steps:
(1) heating RO water to 60-80 deg.C, adding calcium salt, stirring, adding premixed sweetener I and colloid, adding RO water to desired volume, stirring for 20-40min to dissolve completely, heating to 90-100 deg.C, and keeping the temperature for 30min to obtain crystal ball colloid;

In summary, the invention has the following advantages:
1. the invention creatively adopts the crystal ball embedding technology to achieve the purpose of calcium fortification, and compared with the existing products on the market, the invention avoids the phenomenon that calcium salt is directly added into the yoghourt and reacts with the substances in the yoghourt to influence the quality of the yoghourt. The granular substances with chewing feeling such as crystal balls are added into the yoghourt product, so that the interestingness and edibility of the product are enhanced. And the crystal ball is embedded with calcium salt, so that the addition amount of calcium can be greatly increased, and the upper limit (1000mg/kg) of calcium serving as a nutrition enhancer in the national standard is reached.
2. In addition, the existing popple and kiss products in the market are not found to be added with a nutrition enhancer calcium, and mostly cannot resist high-temperature heating or strong mechanical treatment, so that the application is limited. Different colloid materials are selected from the crystal balls as wall materials, so that the crystal balls can resist high-temperature sterilization, and the taste of the crystal balls cannot change greatly even after high-temperature treatment, so that the crystal balls can be applied to normal-temperature products. After a period of shelf life observation experiment, the crystal ball is soaked in the yoghourt without causing the change of the yoghourt base material.
3. The preparation method can embed the crystal ball formula of the calcium salt, adopts the combined action of the calcium ions, the potassium ions and the low temperature to gel the colloid, and can reduce the influence of the added calcium salt on the colloid, thereby ensuring the normal production.
4. The invention provides a formula of crystal balls capable of resisting high-temperature treatment, wherein part of components in the formula have the characteristic of high gel strength, and the taste of the prepared crystal balls is not changed after the high-temperature treatment.
