Description
Technical field
The present invention relates to the Dairy Processing field, particularly, the present invention relates to a kind of sea-buckthorn nutrient milk powder and preparation method thereof.
Background technology
Sea-buckthorn (Hippophae rhamnoides L.) has another name called vinegar willow, acid thorn, deceives thorn, is shrub or dungarunga that Elaeangnaceae (Elaeagnaceae) acid thorn belongs to, generally is grown in the barren mountain area of drying, cold.Sea-buckthorn is the function plant of integration of drinking and medicinal herbs, is widely used in Tibetan medicine, anaesthetic and Chinese medicine in medical circle.Modern scientific research shows, is rich in various bioactivators and nutritional labeling in the sea buckthorn fruit, and burn, radiation injury, canker sore, gastric ulcer etc. are had significant curative effect, and heart disease and tumour are also had good functions of prevention and health care.
In recent years, more and more about the research of the physiological function of oxygen radical and the antioxidant of removing oxygen radical.Oxygen radical is a kind of harmful substance, it is the metabolite of human body, chemical property is very active, aliphatic acid on can the attack cells film produces peroxide, these materials are the very strong a kind of materials of toxicity, and it can be encroached on the interior nucleic acid of body, protein etc. and cause a series of cytoclasis effect, and the oxygen radical accumulation is more in the human body, old and feeble process is just faster, and we common the elderlys senile plaque on the face is exactly because lipid is formed due to the MDA by the oxygenolysis of oxygen radical.Oxygen radical also has relation with many and old and feeble relevant disease, such as arteriosclerosis, hypertension, osteoarthritis, cataract and Parkinson's disease etc.
At present, the way of opposing oxygen radical harm, mainly be the free scavenger of oxygen and antioxidant, its mechanism of action has plenty of directly provides electronics to make the oxygen radical reduction, has plenty of the enhancing activities of antioxidant enzymes, eliminating rapidly free radical, is exactly the important enzyme system that is present in the removing oxygen radical in the middle of the normal structure of human body such as superoxide dismutase and catalase.In addition, these antioxidants such as ascorbic acid, polyphenol compound, carotenoid and tocopherol all have the effect of removing or inhibition oxygen radical.Because the potential toxic and side effect of synthetized oxidation preventive agent, seeking efficient, safe natural becomes one of focus of current research.And sea-buckthorn has very strong anti-oxidation characteristics, can suppress free radical, Apoptosis and DNA that chromium induces and break, thereby have wide medical science prospect.
Common antioxidant has vitamin C (ascorbic acid), polyphenol compound, carotenoid and tocopherols in the fruit.And these antioxidants all appear in the sea-buckthorn and content is abundant especially.Antioxidant can be divided into two large classes in the sea-buckthorn, and a class is water miscible, such as ascorbic acid, polyphenol compound etc.; Another kind of is fat-soluble, such as tocopherols, and carotenoid etc.
In sum, fructus hippophae has significant antioxidation, enhancing immunity and anti-aging effects as a kind of food that enriches antioxidant that contains; Sea-buckthorn has obvious effect for reducing blood fat simultaneously, suppresses oxide to erythrocytic damaging action, postpones erythrocytic deterioration by oxidation.Therefore, it is combined with nutritious milk, both has been conducive to the popularization of sea-buckthorn, provide a kind of health food with better nutritive value for people again.
At present, the product of fructus hippophae processing exploitation mainly contains sea-buckthorn fruit beverage, sea buckthorn fruit wine and seabuckthorn yoghurt, does not also have to add in the milk powder relevant report of fructus hippophae.The present invention adds seabuckthorn fruit powder in milk powder, not only improved the nutritive value of milk powder, made it have effect anti-oxidant, anti-ageing and the enhancing immunity of organisms, and the speed that can slow down the milk powder fat oxidation, prolong the holding time of milk powder, i.e. shelf-life or shelf life.The shelf-life of milk powder is 18 months or 24 months on the market now, although it is little that the various nutritional labelings within the shelf-life in the milk powder change, but at the rear some months near the shelf-life, the taste smell of milk powder changes greatly, in various degree have a rancidity that produces behind a kind of Oxidation of Fat and Oils.This mainly is because milk powder causes with the prolongation of holding time or through hot weather fat accelerated oxidation.The bad smell that this fat oxidation produces has a strong impact on the milk powder mouthfeel, and its organoleptic quality is descended.This phenomenon is especially obvious in baby formula milk powder, because contain the aliphatic acid such as various plants oil and DHA and AA in the baby formula milk powder, the higher easier oxidation of product fat content.The taste smell variation that causes in order to solve fat oxidation, milk powder manufacturing enterprise needs to add artificial antioxidant in milk formula, such as arabo-ascorbic acid, vitamin E, tocopherol etc.Artificial synthetic antioxidant to human body particularly the infant potential hazard is arranged, and solve the method that the fat oxidation problem is a kind of very safety and Health with containing the seabuckthorn fruit powder that enriches natural.
In the actual production process of milk powder, the addition of seabuckthorn fruit powder is difficult technical problem of holding.The seabuckthorn fruit powder addition is too little, and not only do not have anti-ageing and improve the health-care effect such as immunity, and also namely also not obvious as the effect of milk powder antioxidant to slowing down milk powder fat oxidation speed, can not guarantee that milk powder taste within the whole shelf-life is constant.But, excessive such as seabuckthorn fruit powder addition in the fruit-milk powder, can bring problem to production technology, mainly be wall sticking phenomenon in the spray-drying process.The sticking wall material that refers to be dried is attached on the inwall of drying tower.Material behind the sticking wall might be burnt or be gone bad owing to rest on for a long time on the inwall of heat, affects product quality.Sticking wall material can cause product yield to reduce owing to can not in time be taken out of drying tower by wind.When wall sticking phenomenon is serious, have to shorten and wash the tower cycle, cause production capacity to descend.And the main cause that produces wall sticking phenomenon is because the softening point of dried material is lower than baking temperature, and particle melting under baking temperature is clamminess, and causes sticking on the hot wall, causes sticking wall.Sea-buckthorn milk powder wall sticking phenomenon mainly is that the seabuckthorn fruit powder that adds causes, owing to contain more carbohydrate and gelatin substance in the seabuckthorn fruit powder, softening point causes wall sticking phenomenon easily about 70 ℃.Therefore, both guaranteed that prepared sea-buckthorn milk powder was with health role, do not brought problem to production technology again, will determine the optimum addition of a seabuckthorn fruit powder.
