1, can I still drink if the fermentation fails?
As long as there is no pollution, it can be drunk. Milk is food, baking powder is food, but you didn't master the skills in the process of making yogurt and didn't turn it into yogurt. Although you can drink it, it tastes bad.
2. Can you still drink after the second fermentation?
Drinking is ok, but it has lost the function of yogurt. Yogurt will produce a lot of probiotics, which is good for our health, but probiotics can only survive for 3-5 days at low temperature. After secondary heating, probiotics will die with the change of time and temperature, losing the nutrition of yogurt. Attention! If the color turns pink, it means it has gone bad. Don't eat.
3. How long does fermentation take? Less nutrient loss.
When pure yogurt is used as the fermentation source, the fermentation time is 6-8 hours; When yogurt starter is used as fermentation source, the fermentation time is 8- 12 hours.
When the ambient temperature is low or it is made with refrigerated milk, the time should be appropriately extended, but the longest time should not exceed 14 hour, and the longest time should not exceed 10 hour when pure yogurt is used as fermentation source.
4. How high is the fermentation temperature of yogurt?
The temperature of 42℃ is more suitable. When the temperature is lower than 35℃, the fermentation of lactic acid bacteria is too slow, which will lead to long fermentation time and even failure. When the temperature is higher than 45℃, probiotics in yogurt are easily killed by high temperature, and it will also be unsuccessful.
5. Precautions for drinking yogurt
1, not the bigger the better.
Many people like to drink yogurt, and even regard it as a drink, several bottles a day. Experts pointed out that the more yogurt you drink, the better, especially the yogurt with the status of health food, which needs to be controlled. Mengniu Guan Yi Milk is labeled as "people with intestinal dysfunction and low immunity", and the usage and dosage are "one cup twice a day". Experts pointed out that health food is a functional food with specific effects, and it can't be eaten in large quantities at will like ordinary food. But pay attention to the appropriate crowd, usage and dosage, and don't eat too much.
2, can only be refrigerated, not heated.
Many people know that Qian Qian "bacteria" in yogurt is a good thing, but they don't know how to preserve it. Professor Nan Qingxian introduced that when yogurt was first produced, it was full of live bacteria, and only by refrigeration can live bacteria be well preserved. Some people like to drink hot yogurt, which is more luxurious.
3. If you want to drink fruit yogurt, add it yourself.
Liang Ya experts reminded that if you want to enrich the taste of yogurt, you might as well add it at home. Fruit, jam and pulp are all processed by multiple processes, and the naturalness is definitely not as good as that of fresh fruit. If you want to increase the taste of yogurt, you might as well cut the fruit and put it in yogurt at home.
Pay attention to nine points when drinking yogurt.
The stronger the yogurt, the better.
Many consumers think that the thicker the yogurt, the better, but in fact, many very thick yoghurts just add various thickeners, such as hydroxypropyl distarch phosphate, pectin, gelatin and so on. Too much thickener can satisfy the taste, but it is not good for the body.
5. Don't eat yogurt together at will.
Yogurt goes well with many foods, especially breakfast with bread and snacks. It is not only delicious but also nutritious. Yogurt should not be taken at the same time with some drugs, such as chloramphenicol, erythromycin and other antibiotics, sulfonamides, etc., which can kill or destroy lactic acid bacteria in yogurt. But yogurt is very suitable for eating with starchy foods, such as rice, noodles, steamed buns, steamed bread, bread and so on.
6. Don't drink yogurt to lose weight.
Yogurt contains a large number of active lactic acid bacteria, which can effectively regulate the balance of flora in the body, promote gastrointestinal peristalsis, and thus relieve constipation. Studies have shown that long-term constipation has a certain relationship with weight gain. Yogurt also has a certain satiety. Drinking a cup when you are a little hungry can effectively relieve your urgent appetite, thus reducing your appetite for the next meal.
But yogurt itself also contains a certain amount of calories. If you eat more on the basis of the original diet, you will also have the risk of weight gain. The best way is to choose yogurt marked with defatted low calorie. Although their taste is not as rich and mellow as full-fat yogurt, they will have lower calories and will not easily lead to obesity.
7, ham+lactic acid drinks are easy to cause cancer.
People who often eat sandwiches and yogurt for breakfast should be careful. Ham and bacon in sandwiches are easy to cause cancer when eaten with lactic acid drinks (including organic acids). In order to preserve processed meat products such as sausages, ham, bacon and bacon, food manufacturers will add nitrates to prevent food spoilage and the growth of Botox. When nitrate meets organic acids (lactic acid, citric acid, tartaric acid, malic acid, etc. ), it will be converted into a carcinogen nitrosamine.
8. Don't fill your hunger with yogurt.
When you are hungry, you often immediately grab a cup of yogurt and gulp it down? This can really relieve hunger, but it is best not to take yogurt to satisfy hunger. Because the acidity in the stomach is high (ph is 2) on an empty stomach, lactic acid bacteria unique to yogurt are easily killed by gastric acid, and its health care function will be greatly weakened.
Or drink it after meals 1 ~ 2 hours! Because the gastric juice is diluted at this time, the pH in the stomach is most suitable for the growth of lactic acid bacteria. In addition, drinking yogurt at night has more benefits. Remember to brush your teeth in time after drinking yogurt, especially at night, because some bacteria and acidic substances in yogurt are harmful to your teeth.
9. Drinking yogurt is not suitable for all ages.
In fact, yogurt is good, but not everyone is suitable for it. Patients with diarrhea or other intestinal diseases should be cautious when drinking yogurt after intestinal injury; 1 the baby should not drink yogurt. In addition, patients with diabetes, atherosclerosis, cholecystitis and pancreatitis had better not drink sugary full-fat yogurt, otherwise it will easily aggravate the condition. People who are suitable for drinking more yogurt are: regular drinkers, smokers, computer operators, constipation patients, patients taking antibiotics, patients with osteoporosis and patients with cardiovascular diseases.
