Blueberry drink and preparation method thereof

Abstract

The invention discloses a blueberry beverage and a making method thereof. The blueberry beverage is characterized by being prepared from, by weight, 80-90% of blueberry and mulberry mixed juice, 0.025-0.035% of aspartame, 1-2% of xylitol and the balance water. In the beverage, blueberry and mulberry products are adopted, nutritional ingredients are rich, simple mechanical squeezing is conducted, juice and other nutritional ingredients are extracted from squeezed skin dregs, due to sufficient photosynthesis of the surfaces of the skin dregs, the nutritional ingredients are rich, the nutritional ingredients can be directly used for producing the juice beverage after being extracted, the nutrition, flavor and color of the product are greatly improved, and incomparable advantages are achieved compared with those of common juice products. The blueberry beverage has the advantages of being bright in color and not prone to decoloration or deterioration.

Description

technical field [0001] The invention belongs to the technical field of blueberry processing, and in particular relates to a blueberry drink and a preparation method thereof. Background technique [0002] Blueberry, also known as bilberry, is a perennial deciduous or evergreen fruit tree of the genus Vaccinium in the Rhododendronaceae family. It is a high-grade fruit that combines nutrition and health care. The fruit is a small berry, blue-purple when ripe, beautiful and pleasing to the eye, spherical or oval, with white frost on the skin, delicate flesh, and a pleasant fragrance. In recent years, it has also developed rapidly in the south of my country. It is a new type of fruit tree in the ascendant in the development of fruit products in the world today. In addition to conventional sugar, acid and Vc, blueberry fruit is rich in VE, VA, VB, SOD, protein, anthocyanin, dietary fiber and rich in K, Fe, Zn, Ca and other mineral elements. Nutrients such as blueberry anthocyanin...

Problems solved by technology

[0003] With the continuous exploration and understanding of the nutritional function of blueberries, the scale of planting continues to expand, and deep processing has become the only way to meet the market's demand for products and solve the strong seasonality of blueberries. A large number of additives are prepared into products such as fruit juice, fruit wine, jam, capsules and lozenges, so that the nutrient-rich skin dregs cannot be fully utilized, which not only reduces the utilization rate of raw materials and the nutritional value of products, but also pollutes the environment and cannot be realized. Clean production and green ecological requirements; at the same time, some scholars have extracted (water extraction, organic solvent extraction, supercritical fluid extraction and enzyme-assisted extraction, etc.), separation, purification, concentration, A lot of research has been done on drying and other methods, but there are complex processes (time-consuming, laborious, and serious waste of resources), low utilization rate and extraction rate of active ingredients, poor quality and component stability, organic solvents pollute the environment, expensive equipment, and cannot be realized. Continuation, industrialization and other issues

[0004] Blueberry drinks also have many preparations, but generally adopt a single fruit species of blueberries, and all are simple mechanically squeezed juice and then mixed with water, the nutritional components are single, easy to layer, and the shelf life is short; The color of the beverage is diluted, easy to fade and deteriorate, etc.
