Aronia melanocarpa mixed fruit juice having efficacy of resisting oxidation and preparation method of aronia melanocarpa mixed fruit juice

Abstract

The invention provides aronia melanocarpa mixed fruit juice having efficacy of resisting oxidation and a preparation method of the aronia melanocarpa mixed fruit juice. According to the aronia melanocarpa mixed fruit juice, aronia melanocarpa rich in anthocyan and kiwi fruits rich in vitamin C are used as raw materials, and through technologies of performing cleaning, performing squeezing to obtain juice, performing extraction on fruit residues, performing superhigh pressure sterilization, performing bacteria-free cold-filling and the like, the mixed fruit juice rich in anthocyan and vitamin Cis prepared. The aronia melanocarpa mixed fruit juice has favorable efficacy of resisting oxidation, and has favorable efficacy of preventing cardiovascular and cerebrovascular diseases, resisting ageing and the like.

Description

technical field [0001] The invention belongs to the technical field of beverage processing, and in particular relates to a mixed fruit juice of Aronia adenocarpa with antioxidant effect and a preparation method thereof. Background technique [0002] Aronia black fruit is a kind of berry introduced into my country in recent years. Aronia black fruit is rich in anthocyanins and flavonoids, and its anthocyanin content is 80 to 180 times that of grapes. Cranberry 20 to 40 times that of blueberries, 5 times that of blueberries; studies have shown that rich in anthocyanins and flavonoids Aronia adenocarpa has strong antioxidant activity, its antioxidant activity is 2.5 times that of blueberries and 9 times that of cranberries above. Because of its strong antioxidant capacity, it can remove free radicals from the human body very well, and then play a health care role on the human body. At present, there are very few products related to Aronia arborica in China. There are reasons fo...

Problems solved by technology

At present, there are very few products related to Aronia arborica in China. There are reasons for the incomplete industrial chain, and the taste of Aronia berries is rather bitter and unsuitable for direct consumption. Anthocyanins are easily oxidized during processing. s reason

[0003] The existing fruit juice production process generally adopts the following steps: fruit juice extraction-concentration-adding water to reduce to 100% fruit juice-high temperature sterilization-high temperature filling-packaging; this process has the following disadvantages: (1) it needs If the temperature is above 60°C and the processing time is long, the nutrients in the fruit, especially heat-sensitive nutrients such as vitamins and anthocyanins, are easily oxidized, and the original aroma, taste, color, etc. of the fruit are prone to adverse changes or loss; ( 2) The high-temperature sterilization and high-temperature filling process can easily destroy the nutritional value of the product, especially fruits rich in antioxidant substances such as Arana and kiwi
