Description
Technical field
The present invention relates to field of health drinks, relating in particular to a kind of is the health beverages of primary raw material and its preparation method with food containing gingko almond and green tea.
Background technology
Ginkgo, the seed for the Ginkgoaceae plant Ginkgo biloba is commonly called as gingko.Gingko benevolence is a kind of important medicinal, healthy food material; Food containing gingko almond contains nutriments such as protein, fat, carbohydrate, sugar; Contain 25 kinds of elements such as potassium, phosphorus, magnesium, calcium, zinc, copper (editorial board of State Administration of Traditional Chinese Medicine's " China's book on Chinese herbal medicine ";-selected of China's book on Chinese herbal medicine, 2009,5 (3): 237).
Research and analyse through pharmacy, gingko is starch-containing 62.4% ~ 67%, protein 0.3%, fat 2.6%, sucrose 5.2%, reduced sugar 1.1%, nucleoprotein 0.26% and mineral matter 3%.Contain 17 seed amino acids in the gingko, total amount is 10.77%, and wherein essential amino acid is 7 kinds, and content is 3.42%, accounts for 31.8% of total amino acid content, 9 kinds in long-acting amino acid, and content is 1.33%, accounts for total amino acid content 12.3%, has plurality of health care functions.Modern medicine study proves; Gingko has serum cholesterol, increases coronary flow, improves the brain circulation, spasmolysis, loose bronchus and physiological action such as antibacterial; The clinical practice proof is to coronary heart disease, cranial vascular disease, brain disorder, brain injury sequelae and anti-ageing all powerful; Now, the existing many kernels in market are the medicine of primary raw material, the functional food supply.
Green tea is that polyphenol content keeps the highest tealeaves in each teas; Generally remain with the 85%-90% of the bright leaf Polyphenols of tea; Content is about 25%; The catechin and the antioxidant vitamins that contain volume in the green tea like vitamin C, vitamin E and beta carotene etc., have prophylaxis of cancer and the effect that delays senility.And the antioxidation of green tea is nearly 20 times of vitamin E, can reduce oxygen production, effectively removes free radical, and the prevention geriatric disease is had suitable help.Research confirms that green tea also can suppress food preservative-nitrite and change carcinogen at human body, can suppress microsome ferment system and carcinogenic effect, stops the carrying out of cancer process, for benefiting of prophylaxis of cancer.Green tea also helps to reduce fat, and except receiving the effect of fat-reducing, more can improve angiocardiopathy, suppresses blood sugar and rises, and reduces cholesterol and suppresses hypertension.Particularly green tea has significant antibacterial functions, can have the sterilization inhibitory action to human harmful bacteria and virus to many kinds.Tea Polyphenols class material not only can kill harmful bacterium, and can play activation to intestinal beneficial bacterium streptococcus lactis and Bacillus acidi lactici, thereby improves the situation of intestinal flora.Research shows that the active principle in the tealeaves has the effect that promotes growth and propagation to Bifidobacterium.In addition, caffeine in the tealeaves, theophylline, theobromine can excited blood motion maincenters, and directly diastole kidney blood vessel increases the renal blood flow amount, thereby increases the filterability of glomerulus, plays diuretic effect.
Along with the science and technology and the development of health food, the research of ancient tea resource has been obtained very big progress.For example; Tealeaves developed into from the understanding of aspects such as " refresh oneself and recover from fatigue, make eye bright diuresis, the heat-clearing of relieving summer heat " utilize tea extract to carry out hypoglycemic, reducing blood lipid; Prevent angiocardiopathy, Application Research anti-ageing, antitumor, anti-sudden change has all obtained useful achievement.
Along with going deep into to the tealeaves application study; Market supply contains the food, health food, tea beverage, instant tea of tea etc. and constantly is pushed out, and the tea drink class comprises instant tea, tea-cola, tea carbonated drink, tasty tea, hundred sharp treasured, tea health and happiness, canned tea beverage, tealeaves ice lolly and tea wine etc.Tealeaves candy and cake comprise tea sugar, tealeaves biscuit and tea-milk instant beverage etc.Wherein with tea drink, especially instant tea is the most general.At present the major product of China's instant tea has the concentrated tea juice of instant black tea, instant green tea, health-care instant tea and undried, like the oolong tea inspissated juice etc.Also have ginkgo biloba p.e is cooperated the ginkgo leave tea of processing with the Aqua Folium Camelliae sinensis extract, all obtained effect preferably like ZL200510032016.1.
The two all has gingko benevolence and green tea similar effect, the two compatibility to form tea beverage to cardiovascular and cerebrovascular disease, brain disorder, hypoglycemic, reducing blood lipid, anti-ageing, antitumor, anti-sudden change etc. will effect each other to strengthen.Can make the elderly in drinking product of the present invention, obtain better health-care efficacy; Be the new type of health tea of the control cerebrovascular and cardiovascular artery sclerosis, hypertension, senile dementia; Simultaneously to promoting human body metabolism; Enhancing body immunity reduces serum cholesterol, delays body aging and has good health-care effect.
Gingko benevolence and green tea are extracted its active ingredient respectively; Form a kind of new gingko green tea; Health care value to improving ginkgo nut combines with the functional effect that green tea is had; Should be able to solve better and improve its health-care effect, the application approach of widening gingko benevolence is more had actual effect, but relevant report is not arranged in the prior art as yet.
Summary of the invention
The problem that the present invention will solve be exactly with food containing gingko almond and green tea concentrate through extracting, merging respectively, granulation, drying process a kind of novel health beverages; A kind of preparation method of gingko green tea health beverages is provided simultaneously, makes the beneficiating ingredient of the two fully extracted and bring into play more outstanding health-care efficacy.
The objective of the invention is to realize through following proposal:
A kind of gingko green tea is that to be raw material concentrated through extracting respectively, merging, granulation, drying, sterilization, packing are processed with food containing gingko almond and green tea, and it contains the raw material of following weight parts: gingko benevolence 65 ~ 75, green tea 10 ~ 25.
The preparation method of a kind of gingko green tea of the present invention comprises following sequential steps:
