Abstract
The invention discloses a color-protecting processing technology of sulfur-free snow pear juice. The snow pear juice comprises 30 to 60% of snow pear, 0 to 3% of critic acid, 0 to 10% of white granulated sugar, and the balance being water. A color protecting liquid comprises 0 to 10% of chitosan, 0 to 10% of sodium chloride, 0 to 10% of sodium isoascorbate, 0 to 10% of sodium ascorbate, and the balance being water. The processing method comprises the following steps: (1) raw material processing: washing snow pears, peeling, cutting snow pears into blocks, and removing the nucleuses, wherein in the peeling, cutting, and nucleus steps, the raw materials are stored in the color protecting liquid in a storage container for later use; (2) grinding and juicing: mixing snow pear blocks with boiling water with a temperature of 100 DEG C according to a ratio of 1:1, grinding and juicing the snow pear blocks, and storing the snow pear juice in a blending jar; (3) packaging: degassing, homogenizing, and sterilizing the snow pear juice, which has been blended according to the formula, and filling the snow pear juice into package bottles made of a high-barrier PET material under a sterile condition; (4) labeling. The snow pear juice does not contain any sulfite, and the original color and luster of snow pear can still be preserved after six months.
Description
Technical field
The present invention relates to a kind of beverage technologies, be specifically related to one and protect look process technology method without sulphur snow pear juice.
Background technology
Snow pear is nutritious, containing various organic acid, protein, mineral matter and multivitamin etc., except eating raw, and also can the health food of each tool local flavor such as processed can, pear juice, preserved pears, pear wine, pear syrup.Snow pear comparatively other agricultural product has its particularity, very easily brown stain in process.At present, in snow pear product processing, major part uses sulfites material to carry out protecting look.The use of sulphite is with a long history, because of its have concurrently inhibitory enzyme activity, non-enzymatic browning and microorganism effect and be widely used on food, but discovered in recent years sulfites material can cause eater that the diseases such as allergic asthma occur, to human body, there is larger harm, U.S. food medicine administration of health office (FDA) has been forbidden for fresh preserving fruit and vegetable utilizing, and the states such as European Union also expressly provide worked in 2005 the way following U.S. FDA.But because the effect of color protection of sulphite to snow pear product is fairly obvious, China is still general in snow pear Product processing so far, and interpolation use amount has exceeded the requirement of developed country.Therefore work in-process adopts without sulfur to protecting color technology is the current problem in the urgent need to address of snow pear industry, otherwise greatly endangers bringing the health of consumer.
Summary of the invention
The object of the invention is to the deficiency existed for prior art, provide a kind of and protect look process technology method without sulphur snow pear juice.
Object of the present invention is achieved through the following technical solutions:
The invention provides one and protect look process technology method without sulphur snow pear juice.Snow pear juice pulp furnish is: snow pear 30-60%, citric acid 0-3%, white granulated sugar 0-10%, and surplus is water.Colour protecting liquid formula is: 0-10% shitosan, 0-10% sodium chloride, 0-10% sodium isoascorbate, 0-10% sodium ascorbate, the water of surplus.
Protect look processing key technical method link without sulphur snow pear juice and comprise following several respects: (1) Feedstock treating: by peeling after snow pear cleaning, stripping and slicing, stoning, in each process of peeling, stripping and slicing, stoning, raw material is placed in the hold-up vessel that colour protecting liquid is housed and transports for subsequent use; (2) broken juice: snow pear block and the boiling water of 100 DEG C are mixed with the ratio of 1:1 and carries out broken juice, put into blending vat stand-by; (3) pack: by the beverage after formula allotment through degassed, homogeneous, sterilizing, sterile filling enters the Packaging Bottle of high-barrier PET material; (4) labeling: adopt full-automatic label cover mark shrinker, Product labelling is helped mark, strengthens the lucifuge performance of product in Packaging Bottle.
The beneficial effect that the present invention has is: snow pear juice of the present invention is not containing sulfites material, and product deposits the color and luster that can keep original snow pear pulp for 6 months.
