Description

Yellow peach juice and preparation method thereof
Technical Field
The invention belongs to the technical field of peach juice processing, and particularly relates to yellow peach juice and a preparation method thereof.
Background
The peach is originally produced in China, the fruit of the peach is delicious and juicy, and the peach is rich in nutrition, so the peach is popular with people. In recent years, the planting area and the yield of peaches in China are rapidly increased, and the statistical data of the Food and Agriculture Organization (FAO) of the United nations shows that the planting area and the yield of peaches in China respectively reach 1255 ten thousand mu and 1444 ten thousand ton in 2016, and respectively account for 51.1 percent and 57.9 percent of the planting area and the yield of peaches in the world, which are the first in the world. However, the peach harvesting period is relatively centralized, and the peaches are easy to rot and deteriorate due to the influence of factors such as microorganisms, endogenous enzymes and the like after being harvested, so that great difficulty is caused in storage, transportation and sale, and the development of the peach industry is restricted. The deep processing of peaches is developed, the industrial chain of peaches is prolonged, and the method plays an important role in promoting the sustainable development of the peach industry. Peach juice is an important aspect of peach processing. However, the variety of the cultivated peaches in China is mainly white fleshy peaches, and the white fleshy peaches are very easy to brown when processed into juice, so that the color of the white fleshy peaches is dark brown, the sensory quality of the peach juice is greatly influenced, and the processing production of the white fleshy peach juice is severely limited. Although the peach juice can be treated by adding an anti-browning agent such as sulfur dioxide to improve the color, the residual sulfur dioxide in the juice also brings health risks. In recent years, yellow peach develops quickly, the peel and the pulp of the yellow peach are golden yellow to orange yellow and are popular with consumers, and yellow peach juice processed by taking the yellow peach as a raw material has pure color, uniformity and brightness, so the yellow peach juice has better market prospect. However, the yellow peach raw material is limited, so that the cost for preparing the peach juice by using the yellow peach raw material is higher. If the white peach can be used as a raw material, and the safe and healthy yellow peach juice is produced by technical means such as color modification, the problems of excessive production and difficult processing of the white peach can be solved, the shortage of market supply of natural yellow peach juice can be made up, and the requirements of consumers can be met.
The color modification of the peach juice can be realized by adding corresponding pigments. However, the common chemical yellow pigment, tartrazine, is harmful to human bodies and is prohibited to be used in many countries. However, natural water-soluble yellow pigment is relatively lack and high in cost, so that the application of the yellow pigment in fruit juice beverages is limited. Therefore, the development of a simple, safe and efficient peach juice color modification technology is particularly necessary for the production of yellow peach juice.
Disclosure of Invention
The invention aims to solve the problems in the processing of white pulp peach juice in the prior art, and aims to provide a safe and efficient peach juice color modification technology for producing green and healthy yellow peach juice by using white pulp peaches.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for preparing yellow peach juice comprises adding phlorizin and/or phloretin or extract rich in phlorizin and/or phloretin into pulp of white peach; stirring for reaction to make phlorizin and/or phloretin undergo the oxidation reaction to produce yellow pigment.
On the basis of the scheme, the addition amount of the phlorizin and/or phloretin is 0.1-1 per mill of mass fraction.
On the basis of the scheme, the stirring reaction time is 0.5-4 h; the reaction temperature is 20-40 ℃.
On the basis of the scheme, the preparation method of the yellow peach juice comprises the following steps:
1) selecting white peach without rot or worm damage, cleaning, selecting, removing core, and crushing/pulping;
2) adding phlorizin and/or phloretin or an extract rich in phlorizin and/or phloretin into the peach pulp obtained in the step 1); stirring for reaction to make phlorizin and/or phloretin undergo the oxidation reaction to produce yellow pigment;
3) preparing the yellow peach juice from the fruit pulp obtained in the step 2) by the conventional technology.
In the preparation method, the processes in the step 3) can be increased or decreased according to the requirements of the final product, for example, the fruit pulp obtained in the step 2) is subjected to juicing, filtering, sterilizing and filling according to the existing process to obtain yellow peach juice. And when clear peach juice is produced, enzymolysis and clarification processes are added after the juicing process, and when turbid peach juice is produced, a homogenization process is added after the filtering process.
The yellow peach juice prepared by the method.
The technical scheme of the invention has the advantages that:
(1) the phlorizin and/or phloretin used in the invention are polyphenol substances naturally existing in fruits, particularly apples, and have various biological activities of oxidation resistance, blood sugar reduction and the like, and enzymatic oxidation products of the phlorizin and/or phloretin also have stronger oxidation resistance activity and various physiological functions, so that the phlorizin and/or phloretin or extracts rich in the phlorizin and/or phloretin are added, and the phlorizin and/or phloretin are oxidized into natural water-soluble yellow pigment by utilizing the polyphenol oxidase naturally existing in peach fruits, so that the color of the fruit juice is bright yellow; after the enzymatic reaction is carried out, the color of the peach juice can be improved, the antioxidant activity of the peach juice is enhanced, and the peach juice is endowed with stronger physiological function;
(2) according to the method, phlorizin and/or phloretin are directly added into the peach fruit pulp, and the polyphenol oxidase naturally existing in the peach fruit is used for enzymatic conversion, so that the complex procedures of preparing and purifying the yellow pigment by using purified polyphenol oxidase in advance when a phlorizin oxidation product is added exogenously as the yellow pigment are avoided, and the method has the advantages of simplicity, convenience, high efficiency, low cost and the like.
