Rosa roxburghii tratt juice beverage and preparation method thereof

Abstract

The invention relates to rosa roxburghii tratt juice beverage and a preparation method thereof. The rosa roxburghii tratt juice beverage is prepared from the following raw materials in parts by mass:60-80 parts of rosa roxburghii tratt juice, 20-30 parts of concentrated white grape juice, 0.1-0.3 part of a compound stabilizer and 0.02-0.04 part of a compound color fixative, wherein the soluble solid content of the concentrated white grape juice is 40-45%; the composite stabilizer comprises the following main components: CMC-Na, pectin and xanthan gum; and the composite color fixative comprises the following main components: sodium citrate, D-sodium erythorbate and phytic acid. The preparation method of the rosa roxburghii tratt juice comprises the following steps: selecting 80-90% ripe fresh rosa roxburghii tratt, performing quick-freezing, reducing the center temperature of the rosa roxburghii tratt to -20 DEG C to -24 DEG C or below, cutting the rosa roxburghii tratt into halves, removing pedicels, and quickly putting the rosa roxburghii tratt into hot water for blanching treatment for 3-5min; and cleaning, removing seeds, adding diluted lemon and passion fruit juice into the rosa roxburghii tratt without seeds, and carrying out squeezing and filtering. According to the method, the rich nutritional value of the rosa roxburghii tratt is reserved, the browning degree is reduced and kept stable, and the rosa roxburghii tratt juice beverage is high in sensory quality is high and palatable in sour and sweet taste, and has a promoting function on the gastrointestinal function.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a prickly pear juice drink and a preparation method thereof. Background technique [0002] Rosa roxburghii, also known as sending spring back, is a perennial deciduous shrub in the Rosaceae family. It belongs to wild plants and is mainly distributed in Guizhou, Sichuan, Yunnan and other regions. In addition to being rich in functional ingredients such as vitamin C, organic acids, polyphenols and flavonoids, Rosa roxburghii also contains Rosa roxburghii polysaccharides, which are pharmacologically active ingredients, which can improve and enhance the body's immunity. The sugar content of Rosa roxburghii is low and the acid content is high, the fruit taste is sour and astringent, and the quality of fresh food is poor. Most Rosa roxburghii are used for processing roxburghii juice and preserved fruit. [0003] Rosa roxburghii fruit is rich in a variety of nutrients, which are prone to...

AI Technical Summary

Problems solved by technology

[0003] Rosa roxburghii fruit is rich in a variety of nutrients, which are prone to chemical reactions and losses during processing and storage, resulting in browning of juice color, deterioration of taste, and escape of flavor substances, making the quality of roxburghii juice products fluctuate greatly, which is difficult to obtain. Let the prickly pear, a superior natural resource, reflect its advantages in the market circulation and consumption cycle

In particular, most of the existing thorn pear juice drinks on the market are clear juices with a single type and a relatively high degree of browning

Studies have shown that the main cause of browning is the oxidation reaction of phenolic substances, the reaction of metal ions catalyzed pigment substances or the oxidation of ascorbic acid, etc., but at present, in order to solve the above problems, most of them use food additives to achieve the purpose of color protection, and there is no processing technology. conducted research, resulting in the loss of original nutrients in prickly pears
