" productive technology of Chinese chestnut can " (application number 97106149) provides a kind of productive technology of Chinese chestnut can: the chestnut meat that Chinese chestnut shells after treatment, plants behind the benevolence epidermis soaks in alum water, after will trembling the meat washing, degassing process goes into pot, and adding sodium sulfite, after adding the water heating, use cold water flush, in bleaching process will be equipped with the pot of chestnut meat, add water, and add EDTA and sodium sulfite, heating back cold water flush; To tremble the meat tinning after in softening process will be equipped with the pot of chestnut meat, adding water heating, cooling.
The disclosed method for making of " Chinese chestnut nectar and method for making thereof " (application number 95105318) is earlier the Chinese chestnut fruit to be put into water or boil liquid and boil, and the Chinese chestnut that will boil is put into beater and pulls an oar then, sieves, and is levigate.Subsequently,, evenly stir, put into homogenizer and do the homogeneous processing by the prescription allotment.At last, get fruit tea through the degassing, sterilization, can.
Summary of the invention the objective of the invention is at above-mentioned present situation, aims to provide a kind of no brown stain, mouthfeel is good, Chinese chestnut is with rich flavor, cost is low, heat is low, helps the primary colors of health, the production method of low sugar chestnut product.
The implementation of the object of the invention is, the production method of primary colors, low sugar chestnut product, Chinese chestnut is through peeling off, endothelium-denuded, adding the colour protecting liquid boiling and get Chinese chestnut benevolence, Chinese chestnut benevolence gets low sugar Chinese chestnut Rong product through beating process, colour protecting liquid is made up of sodium phosphate trimer, EDTA, VC, citric acid and distilled water or pure water, and the percentage concentration of each composition is than being sodium phosphate trimer: EDTA: VC: citric acid=0.05%: 0.025%: 0.15%-0.3%: 0.15%-0.3%.
The present invention peels off Chinese chestnut, endothelium-denuded, add the colour protecting liquid boiling and get Chinese chestnut benevolence, makes low sugar Chinese chestnut Rong product through beating process again.With the Chinese chestnut benevolence that this method makes, also can process Chinese chestnut benevolence product, sugar-free Chinese chestnut can, low sugar Chinese chestnut nectar etc.
Production method of the present invention has following characteristics:
1, adopts color stabilizer that Chinese chestnut is handled, can avoid the brown stain of Chinese chestnut product;
2, directly Chinese chestnut is boiled and controls the shortening time, pre-liquor turns back to syrup preparation link after filtering, has guaranteed no tiny broken kernel and sediment in the jar, guarantees that juice is limpid, transparent, look light, Chinese chestnut is with rich flavor;
3, with albumen sugar place of sucrose, albumen sugar is a kind of good sweetener, under the situation that is no more than the food additives standard, can make the sense of taste of food such as Chinese chestnut can, Chinese chestnut benevolence good, heat reduces, and helps health, help reducing the cost of Chinese chestnut can and Chinese chestnut benevolence simultaneously
Because of the low oil product of low sugar is made filling material plasticity, elasticity is relatively poor, therefore easily sticking pot in prescription, can make the product total sugar content be reduced to below 20% with the starch syrup place of sucrose, and help to improve product quality in the frying process;
