Background technology
Fresh milk junket is in Ruzhong, to add appropriate lactic acid bacteria, leavening and renin, makes after protein coagulating, gets rid of whey, grumeleuse is pressed into bulk and the product made, and its main nutrient composition is protein and fat.Owing to needing to remove whey in fresh cheese-making, the materials such as lactalbumin and most vitamin, trace element are all discharged with whey, reduced the nutritive value of fresh milk junket, and this fresh milk junket taste are single.
Red date has high nutritive value and medical value.In the herbal medicine books [herbal classic] of China, record, sweet warm in nature, the taste warp of red date taste, has tonifying middle-Jiao and Qi, nourishing blood and tranquilization, and nourishing stomach and spleen, relaxes the effects such as the property of medicine.The chemical composition of red date mainly contains several amino acids, vitamin A, vitamin B2, the vitamin Cs such as protein, aspartic acid, glutamic acid.Through analysis center of the Chinese Academy of Sciences, measure, the water content in dry jujube is 22~26%, and sugar content is 55~80%, crude fibre 2.41%, crude fat 2.41%, crude protein 2.92%, phosphorus 0.09~1.27%, potassium 0.65~1.05%, manganese 4.37~7.82mg/kg, iron 11.5~65.5mg/kg, calcium 0.03~0.06%, copper 2.45~5.88mg/kg, magnesium 0.03~0.05%, zinc 2.12~14.98mg/kg, Cobastab
10.17mg/100g, Cobastab
20.35mg/100g, vitamin C 87mg/100g, carrotene 0.4g/100g.In red date, contain 16 seed amino acids, wherein 8 kinds is arginine and the histidine that essential amino acid and child cannot be synthetic.
Purple sweet potato (purple potato) contains abundant dietary fiber, carrotene, vitamin A, Cobastab, vitamin C, vitamin E and potassium, iron, copper, selenium, calcium etc. more than 10 plants trace element and linoleic acid etc., its nutritive value is very high, by nutritionists, is called the most balanced health food of nutrition.In purple potato, the content of purple anthocyanidin and selenium is up to 0.122mg/g and 0.0071 μ g/g.Active trace elements of selenium element in purple potato is easily absorbed by the body, and can effectively stay in blood and strengthen Abwehrkraft des Koepers, removes the free radical that produces cancer in body, the generation of pre-anti-cancer.Studies have shown that, purple have the stronger function that removes oxygen radical, and its ability of removing free radical is ascorbic 20 times, 50 times of vitamin E.Purple potato anthocyanidin can significantly improve aged mouse serum consumption rate, significantly suppresses the generation of MDA in aged mouse serum and improves the activity of superoxide dismutase and whole blood glutathione peroxidase in serum.Dietary fiber can prevent and treat the various diseases such as intestinal cancer, constipation, hemorrhoid, diabetes, heart disease, high-cholesterol disease and obesity, is called as the seventh-largest nutrient after water, carbohydrate, protein, fat, vitamin, mineral matter.
Hawthorn is rich in protein (be Apple protein content 17 times), 18 seed amino acids (8 kinds of needed by human), carbohydrate, mineral matter (calcic in fruit row first), vitamin (vitamin C, A, B
1, B
2), the multiple nutritional components such as flavonoids, three note classes (ursolic acid, crataegolic acid, oleanolic acid etc.), other compositions (chlorogenic acid, epicatechol, choline etc.), there is very high nutritive value.Flavonoids from Hawthorn leaves content is up to 2%, is 20~120 times of fruit content.Flavone compound has Green Tea Extract, antioxidation, anticancer, antitumor action, multiple pharmacology and the health-care effects such as anti-diabetic and complication thereof.At present, also red date, purple potato and hawthorn and fresh milk one are not used from both at home and abroad to the correlative study report of processing fresh cheese.
