Unlike milk calcium lactate
Although this problem is a long talk older students , but we Calcium lactate are in most state of calcium deficiency , and now there is a lot of calcium products , so that consumers are very difficult to identify the authenticity. Many products are now vigorously promote calcium absorption . What is the best calcium it ? That is, biological calcium. In biological calcium milk calcium is the best calcium. Unlike milk calcium lactate, calcium is milk cheese processing by-products from whey discharged by precipitation , concentration and spray processes to extract from.
Currently our residents about daily calcium 500 ~ 700mg, with statistics of China's current residents drank milk volume 200 ~ 400ml. Domestic milk milk calcium content is generally 90 ~ 120mg/100ml, ie the amount of drinking milk now is not able to fully meet the calcium effect. Now many buffered lactic acid are also introduced high calcium milk , but adding the calcium in milk is not the same kind , be the absorption of calcium have a great impact .

Yogurt is the most important indicators of lactic acid bacteria
Yogurt is the most important indicators of lactic acid bacteria ( live ) content indicators , calcium ( lactate ) and heat indicators , can these items are not marked in our yogurt reflected . Calcium lactate in yogurt lactic acid bacteria under the effect of lactose , into organic acids ( lactic acid, acetic acid, formic acid ) and ethanol in the colloidal calcium phosphate (salt ) is converted into soluble calcium lactate , calcium lactate high solubility , absorption, so, to say yogurt is one of the two biggest advantages can be quickly charged calcium.
Yogurt is both an ancient food , but also a development potential of healthy food. The quality of it is not only related to the health of consumers , but also related to the rise and fall of the dairy business . Here again introduced the characteristics of other yogurt , flavored yogurt yogurt is more familiar , this yogurt is divided into dilution type (P ≥ 1.7%), ordinary type (P ≥ 2.3%) and concentrated (≥ 2.7%), we saw in the Chinese market, almost all ordinary type . Other yogurt include : fruit yogurt , buffered lactic acid , strong sugar yogurt , strengthen yogurt , soy yogurt , whole milk ( plain ) yogurt , half nonfat yogurt , nonfat yogurt , frozen yogurt, etc. , as well as probiotic yogurt , low sodium yogurt , anti-caries inflatable yogurt yogurt and dozens of varieties . These yogurt each with their own characteristics, so need to have their own standards. However, due to China's dairy standards work is seriously lagging behind , many varieties of yogurt should be produced without producing . This explains some of the thinking behind the dairy sector expertise , professional knowledge poor and low management level .
