High-thermal-stability blueberry nutritional soft sweets with bone-strengthening and health-care effects and preparation method thereof

Abstract

The invention discloses high-thermal-stability blueberry nutritional soft sweets with bone-strengthening and health-care effects and a preparation method thereof. The blueberry soft sweets disclosed by the invention consist of the following raw materials: freeze-dried blueberry powder, gelatin, pectin, agar, gellan gum, white granulated sugar, malt syrup, potato acetate starch, sodium citrate, citric acid, malic acid, purified water and a small amount of natural essence. The invention further provides a preparation process of the functional mixed gum type soft sweets, and effective componentsof blueberries are reserved to the maximum extent. The functional component of the blueberry health-care soft sweets is the freeze-dried blueberry powder; the freeze-dried blueberry powder is uniformly dispersed in the soft sweets and is easy to absorb, and has the health-care effects of strengthening the bones and preventing bone loss; various gel system formulas are adopted in the soft sweets, so that the problem of heat stability of traditional gelatin soft sweets is emphatically solved; and the soft sweets are good in taste, convenient to store and stable in quality, and the requirements of consumers on the taste and quality of the soft sweets are met.

Description

technical field [0001] The invention belongs to the technical field of health food, and in particular relates to a high-heat-stable blueberry nutritious jelly with bone-enhancing and health-care effects and a preparation method thereof. Background technique [0002] Osteoporosis is a systemic skeletal disease, often accompanied by decreased bone mass and microarchitectural deterioration of bone tissue, which can lead to increased bone fragility, thereby increasing the risk of fracture. It is common in postmenopausal women and the elderly, threatening people's health. As we all know, various bone problems generally occur in middle-aged and elderly people. Most of these bone problems are caused by decreased bone density. To avoid various bone problems, except for middle-aged and elderly people People need timely intake of nutrients for bone health, and effective bone density reserves should also be carried out during childhood. During the growth and development period of child...

Problems solved by technology

[0009] The first purpose of the present invention is to solve the problem of poor thermal stability of soft candies on the market. When the temperature is high in summer, the soft candies are prone to colloidal melting. The present invention focuses on the thermal stability of blueberry soft candies. It was shown that the compounding of gelatin, modified starch and gellan gum can effectively increase the melting temperature of gelatin fudge. Therefore, through the formulation optimization and process improvement of the compounded gum, the fudge formula that can maintain a good shape at 50°C was screened out and prepared. The high heat stability gelatin fudge produced has excellent appearance, good elasticity, good taste, convenient storage and stable quality
