Description

Natural Rosa roxburghii-pears composite juice and preparation method thereof

Technical field

The present invention relates to a kind of natural Rosa roxburghii-pears composite juice and preparation method thereof, belong to technical field of beverage.Be to be the composite fruit juice of major ingredient making with pears and Rosa roxburghii.

Background technology

The Chinese fruit aboundresources, wherein pears output is at the forefront in the world.Along with the sustained and rapid development that China fruit is produced, the rolling up of fruit output, fruit processing industry also is high speed development situation.Various fruit juice, fruit-vegetable juice beverage gross annual output amount reach 2,120,000 tons, and quality increases.However, the fruit of China is processed in and also lags far behind the development that fruit is produced generally.At present, nearly 7,000 ten thousand tons of China's fruit gross annual output amount, and the fruit that is used to process has only 6,000,000-7,000,000 tons.Because fruit output is huge, has surpassed the needs of eating raw greatly, add that the fresh fruit article are difficult for storage, annual a large amount of fruits rot, and cause very big economic loss, are unfavorable for that the orchard worker increases income.So, greatly develop fruit processing, improve fruit and be worth the task of top priority that has become China's agricultural development.

Pears have the title of " ancestors of all kinds of fruits "; The nutritive value of pears is higher; Sugar content is more than 8%; The most nearly 20%, bright the operatic circle contains trophic factors such as protein, calcium, phosphorus, iron, carrotene, thiamine, riboflavin, and have concurrently slake thirst and help produce saliva, the function of the analgesic moistening lung of relieving summer heat, reduce phlegm, relieving cough and asthma, defaecation diuresis.

Rosa roxburghii ( Rose roxburghiiTratt.) have another name called rosa roxburghii, Wen Xianguo, send the spring return, oblonga, be rose family Rosa wild plant, machaka originates in the Yunnan-Guizhou Plateau, is the special product wild resource of western mountainous areas such as China's cloud, expensive, river.Through artificial domesticating cultivation, also there is plantation in provinces such as Shanxi, Shandong, Henan, Anhui now.National artificial cultivation Rosa roxburghii area reached 1144.7hm in 1989 ², wherein Jiangsu Province's cultivated area accounts for 60% of the whole nation cultivation gross area.Rosa roxburghii is rich in Vc, also contains abundant SOD, Rosa roxburghii polysaccharide, Rosa roxburghii flavones, eight kinds of amino acid, citrin, Cobastabs that human body is necessary ₁, Cobastab ₂, vitamin E, vitamin K ₁Reach various trace elements such as selenium, calcium, phosphorus, iron, zinc.Fruit of Grossularia burejensis Berger has very high medicinal and health care and is worth, and is a kind of medicinal fruit that improves the health, prevents and cures diseases.Fruit of Grossularia burejensis Berger is at the digestion-promoting spleen-invigorating that is used among the people, or its fruit and root are used as medicine, and is used for digestion-promoting spleen-invigorating, astringing to arrest diarrhea and relieving summer-heat, and supplementary Amplifications of the Compendium of Materia Medica has and carries, and modern " Chinese medicine voluminous dictionary " also records.The functional effect of Rosa roxburghii mainly contains: improve plasma antioxidants and low-density lipoprotein (LDL) oxidation resistance, improve human body SOD content, delay senility; Anti-anoxic, antifatigue; Reducing blood lipid; Antiatherosclerosis; Anti-cancer and cancer-preventing; Effectively reduce heavy metal loads such as manganese, arsenic, lead; And to CCl ₄The protection of the hepatic injury that causes; Rosa roxburghii flavones prevention diabetes; Impel the rat stomach liquid measure, total acid output and peptic activity of stomach increase, and promote choleresis; Anti-inflammatory and antalgic, anti-sudden change, anti peroxidation of lipid improves other pharmacological actions such as mouse fecundity.

China's pears resource and Rosa roxburghii aboundresources; Research pears-Rosa roxburghii composite fruit juice can be expanded Rosa roxburghii, pears further technological processing way, helps solving the peasant and buys the difficult problem of fruit, is beneficial to increasing peasant income; Effectively realize the conversion of resources advantage-market advantage-economic advantages; Improve added value of product, produce huge economic benefit, drive development of regional economy.

Summary of the invention

The present invention provides a kind of natural Rosa roxburghii-pears composite juice and preparation method thereof.

The present invention realizes with following technical scheme: a kind of natural Rosa roxburghii-pears composite juice; It is that primary raw material is processed into Rosa roxburghii and pears; The weight portion of each raw material is: 36 parts of pears, 5 parts of Rosa roxburghiis, 0.00023 part of xanthans, 0.00023 part of acid sodium carboxymethylcellulose.

The preparation method of a kind of above-mentioned Rosa roxburghii-pears composite juice, produce as follows:

(1) after the selected cleaning of pears and Rosa roxburghii, pears and Rosa roxburghii are cut into piece.

(2) it is broken pears piece, Rosa roxburghii piece and water to be put into refiner, and the ratio of pears piece, Rosa roxburghii piece and water is 36:5:5.

(3) squeezing system juice.

(4) enzyme that goes out: the pear juice of squeezing is kept 45s, deactivation polyphenol oxidase and peroxidase wherein at 80 ℃.

(5) homogeneous: 25MPa, 60 ℃.

(6) centrifugal: with the centrifugal 15min under the 4000rpm condition of the fruit juice behind the homogeneous.

(7) allotment: the upper strata juice after centrifugal adds xanthans and acid sodium carboxymethylcellulose, stirs fully.

(8) degassing: at 0.1mPa degassing 5min.

(9) bottling add a cover, boiling water bath 10min sterilization, segmentation is cooled to room temperature then, promptly obtains finished product.

Because pears contain the abundant aldehydes matter that physiologically active is arranged, and Vitamin C content is less, the effectively anti-exactly brown stain material of vitamin C is so be prone to take place the loss that enzymatic browning causes the aldehydes matter aldehydes matter in the pears processing.And Rosa roxburghii contains abundant vitamin C; The present invention utilizes natural Vc in the Rosa roxburghii as the anti-enzymatic regent in the pear juice processing; Not only prevented in the processing enzymatic browning, reduce external source Vc and even do not add external source Vc saving production cost, and can produce the high-quality suspended pulp that is rich in the complementary pure natural of two kinds of fruit nutritions.

The invention has the beneficial effects as follows, do not add sweetener and acid in the production process, at utmost near the fresh fruit local flavor; Quality is even, and color and luster is milky white, sweet and sour palatability; Have the characteristic fragrance of pears, be rich in mineral matters such as vitamin C, phenolic material, calcium, phosphorus, iron, be fit to various drunk by people.

The specific embodiment

Embodiment 1

Take by weighing raw material in proportion.

The first step is the selected cleaning of pears and Rosa roxburghii, pears is cut into the square of about 4 centimetres of the length of sides, with all two lobes of Rosa roxburghii.Second step was that 360 kilograms of pears pieces, 50 kilograms of Rosa roxburghii pieces and water are put into the refiner fragmentation for 50 kilograms.The 3rd step was with the squeezing of the slurry after fragmentation system juice.The 4th goes on foot the enzyme that goes out keeps 45s one deactivations polyphenol oxidase and peroxidase wherein with the juice part at 80 ℃.The 5th step was homogeneous (25MPa, 60 ℃); The 6th step was with the centrifugal 15min under the 4000rpm condition of the fruit juice behind the homogeneous; The 7th step was the fruit juice of getting from caring, and toward wherein adding 0.0023 kilogram of xanthans and 0.0023 kilogram of acid sodium carboxymethylcellulose, can dissolve xanthans and acid sodium carboxymethylcellulose earlier before adding, and stirred fully after the adding fruit juice again; Also can a little sucrose and xanthans, the acid sodium carboxymethylcellulose done fully be mixed thoroughly, add fruit juice more in the lump and fully stir; The 8th step was at 0.1mPa degassing 5min; The 9th step was that 10min is added a cover, in boiling water bath, keeps in bottling, and segmentation is cooled to room temperature then, promptly obtains 460 kilograms of finished products.
