The preparation method of Fe-rich soybean food
Technical field
The present invention relates to a kind of preparation method of soy food product, relate to particularly a kind of preparation method with soy food product of iron replenishing function.
Background technology
Along with the progress of human civilization and the sustainable development of national economy, people more and more pay attention to the health of self.Modern medicine thinks, the reason of anaemia is a lot, and iron deficiency is common a kind of, because iron is the important component of hemoglobin, and hemoglobin is responsible for the oxygen infusion in blood to each Organ and tissue of whole body.The people of iron deficiency, owing to can't obtain enough oxygen, the energy that health produces reduces, will feel asthenia universalis, dizzy, irritated forgetful, pale complexion, even be short of breath, palpitaition etc., people often are referred to as hypoferric anemia.In food, iron deficiency easily causes hypoferric anemia, usually causes physical work capacity to lower, and cognitive ability goes down, and therefore degradation under immunocompetence, for effectively preventing hypoferric anemia, needs to take in food or the medicine that is rich in iron.And what can utilize due to human body is ferrous iron (as ferrous fumarate, ferrous sulfate etc.), and therefore, existing benefit iron medicine or food mostly are ferrous compound or complex compound, it is expensive, take improper easy generation toxic and side effect, and multi-band has unpleasant pungent taste, mouthfeel is not good.
Certainly, in order to prevent that anaemia from occuring, the also higher food of iron-holder such as edible black fungus, black fungus is a kind of natural tonic, be in various foods iron content the highest, mend the best food of iron effect, Nutritional studies shows: in every 100g black fungus, iron-holder is approximately 98 milligrams, exceeds 5 times than the pork liver that in animal-derived food, iron-holder is the highest, exceeds 30 times than the spinach that in plant source food, iron-holder is the highest.In addition, black fungus also contains proteins,vitamins,minerals, lecithin and the cephalin etc. of needed by human body, nutrition and abundant.American scientist research is found, often eats the content that black fungus can suppress platelet aggregation, reduce Blood Cholesterol, and is rather useful to coronary heart disease, artery sclerosis, the cerebrovascular etc., and certain anticancer effect with dissolving calculus is arranged.But the iron that contains in black fungus exists the utilization that is difficult to be absorbed by the body, problem that bioavilability is low.
Come in, phytoferritin obtains consumers in general's approval gradually as a kind of novel, natural ferrous supplement method.Phytoferritin is the main existing way of inherent iron in plant, can with soluble, nontoxic, and can be by the form of biological utilisation storage iron atom.The member of non-heme iron group in originating as dietary iron, ferritin is the compound that contains ferric ion, its inside can store the ferric ion of 4500.A large amount of result of the tests show, body is the same to the absorptivity of iron in purifying ferritin and ferrous sulfate, illustrate that ferritin is very effective iron nutrient source.Important a kind of as in ferritin, soybean ferritin also can well be absorbed by human body, utilize.But, owing to containing a large amount of phytic acids in soya bean, be difficult to be absorbed by the body with the iron of its combination, and in the preparation process of soy food product, a part is combined in iron in soybean ferritin and can discharges with phytic acid and be combined, and the iron absorptivity of soy food product is reduced greatly.Therefore, for improving the absorptivity of Iron in Soybean, soybean ferritin need to be purified out from soybean, and the method for above-mentioned purifying soybean ferritin wastes time and energy often very much.
