question 2: Under what circumstances will the yeast be defeated! Satisfied answer favorable rate: 1% Did you use boiled water to make noodles? If it is, it's scalding the yeast. Also, if the yeast lasts too long, it will die. Besides, it's cold now, and the effect of dough making is not good. You'd better use a warm bath to make dough. Put the noodles in a food bag and seal them, then put them in a small metal basin (with good heat transfer), and then sit the small basin in a warm water bath. Not too hot. When it is cold, add some hot water and keep it at about 3 degrees. It's better to be below 3 degrees than above 3 degrees. Continue to ask: no, this has not happened! I asked for my friend! Supplementary answer: it may be expired, or it may be a fake. Although general mechanical stirring is harmful to yeast, it has a good protective effect in dough and will not be killed by mechanical damage. Keep asking: Do you bake? Supplementary answer: no, just like it, the level is average! I have been making pasta since I was a child. But I am a student of biology and know the influence of mechanical damage on microorganisms, hehe.
question 3: can angel yeast still be used after its expiration date? Not recommended.
It is stipulated in the industry that Angel Yeast will reach the shelf life one month in advance, because the activity of yeast will not be exactly the same as the experimental results, so manufacturers are required to advance the date by one month. If the storage method of the manufacturer is not very reasonable, it is very likely that the yeast has expired.
Yeast is a very nutritious thing, which has lost its activity, but its nutrition is still there. It is a good choice to water flowers and raise goldfish. Dry yeast should be used as soon as possible after opening the bag, because it will lose its activity soon after opening the bag.
Question 4: Will the yeast fail at -18℃? It depends on the situation. If the general test-tube culture medium is placed at -18℃ for a period of time, it will not fail. The situation is different according to different yeasts. The following is the situation in which the strains in our laboratory are kept in the refrigerator for one year. For reference only
Trichosporon survives
Cryptococcus fails
Willebrand partially fails
Geotrichum sp. survives
Galactomyces partially fails
Candida Ca. Ndida survives
Wickerhamomyces fails
Sac-charomyces cerevisiae survives
If the strain is made into glycerol tube, it can be permanently stored in ultra-low temperature refrigerator.
Question 5: Will Angel's yeast powder fail after being opened for several months? It's useless. The shelf life refers to the condition of good packaging. It has been opened and lost its activity after so long.
question 6: how long will the yeast fail? don't lose weight just to eat! Losing weight depends on exercise is the best!
no hunger strike (vomiting is also counted)! I don't know about the earthquake. There are no injured people under the ruins, and there will be no water for three days! Seven days without food and water! The opportunity to live without food and water for seven days will become organ failure, but it will still be! It is usually 7 days without digging for help (you will create a miracle of life, you will hunger strike).
It's not how to lose a little weight in diet. The average stomach can hold 1-3 tons of grain. You count your three meals and eat a lot of pounds. That's what excited you four days ago. From 3 days to 7 days, a part of the fat will be consumed, but people are always so weak that they only see food with blue eyes, fierce eyes, black eyes standing there, dizziness and other symptoms ... (Hang up ~ ~ ~). Most people don't have the same underground prison, and they will eventually give up. Maybe you have the nerve of steel, lofty belief, persistence and persistence, ideal ... but you have to persist in eating all your life? When you resume your diet, your last day, the rebound begins! Because of the long-term hunger, you have superior digestion and absorption ability, and the speed that will make you reach the speed of light is terrible and fatter than before! Exaggerated, which means it should be easy to understand! )
food replaces diet, but the principle is that you are cheated by hungry and nutritious food, and you should eat more foods with high water content and low calories and fill your stomach with those plants. When they are herbivores? Lovely herbivores have eaten a few pounds of grass. Can you eat some plants to hold? ), in this way, the same suffering and dieting to lose weight, then this is not the explanation.
They all said that they should eat fruits to lose weight: apples, lions, peaches, watermelons, pomegranates, tomatoes, strawberries, lemons, grapefruit, hawthorn, bananas, watermelons, pineapples and kiwis ...
They said that eating vegetables to lose weight: cucumbers, white gourd, lettuce, Chinese cabbage, spinach, lettuce, leeks and carrots ... Brown rice ...
I have to say that drinking slimming drinks: water, milk, beer, yogurt, all kinds of tea, and all kinds of vinegar ...
Sleeping, staying up late, smoking, KISS losing 5 costs 8 ...
Unfortunately, more than 99% of them are ineffective. After eating these things for thousands of years, Maybe the topic of losing weight can only be found in history books, but if you see fat people, you have to go to medical school to find cans. Wake up! (1% of these exceptions are abnormal human rights. They are X-men ..........................................................................................................................................................
From a rational point of view, under all external conditions, habits remain unchanged ...
Then unexpected circumstances (such as drugs, diet, or psychological factors) are added, weight loss is successful ...
And an extra emergency disappears, do you think it will rebound?
Answer the question, why did you open your mouth so wide? The reason why you couldn't? I saw your dinner yesterday ...
You only keep one, so that you can lose weight and not rebound in more emergencies.
Everyone's opinions and understanding of the world are different in this course. Maybe you think my opinion is wrong. You can find the ideal answer in your heart.

question 7: how can yeast powder be preserved so as not to lose its efficacy? Just find a sealed glass bottle and put it in the freezer.
Dry and refrigerate at low temperature!
question 8: what should I do if the yeast powder is out of date? 1. After the yeast is dissolved in warm water, wait for 5-1 minutes. If the yeast has good activity, a layer of foam will soon float on the surface. If there is no floating foam or the foam is not obvious, it means that the activity of yeast is not very good and can not be used again.
2. Add 1/2 teaspoon of sugar to warm water, which is used as nourishment for yeast, so that yeast can grow rapidly and be easy to observe.
3. If the dried yeast you buy is a big bag, it can be stored at room temperature before opening. After opening, please put it in a sealed bottle and put it in the refrigerator (5℃ is the best). The sooner you use it, the better. For home use, it is recommended to buy yeast in small packages to avoid losing its activity after a long time of use.
4. The reason why the dough does not rise is not necessarily the yeast. The temperature of the dough, the content of oil and salt, etc. will affect the fermentation speed and effect. But yeast failure is the most common problem. Therefore, testing whether yeast is active can prevent us from making the simplest mistake and let us not fail at the starting point.
Question 9: Can you put some new yeast in the failed yeast? Is it delicious? Fermented cake with whipped cream
Ingredients: whipped cream: 15g, low-gluten flour: 1g, white sugar: 35g, dried yeast: 1g, egg: 1
Practice:
1. Mix whipped cream and white sugar evenly, heat it in the microwave oven. It's best to stir until the white sugar is dissolved
2, add dry yeast and stir evenly
3, and let it stand for 15-2 minutes to activate the yeast, and you can see some small bubbles on the surface (it's cold, I put a plate with hot water on the bottom)
4, add an egg and mix well
5, add the sieved low powder and mix well
6.
Tips:
1. Because whipped cream contains oil, yeast is not easy to dissolve, which is normal, so it should be left for a while
2. My mold is very small. If everyone uses a larger mold than mine, To prolong the time, please

Question 1: Yeast is usually the most active, and the highest temperature will fail. Hello, to maintain the maximum activity of yeast, temperature control is the most important thing, that is, in the production process. Basically, the yeast loses its activity when the temperature is above 4℃, so we must pay attention to controlling the water temperature. Here are some tips for you. < P > Because most bread factories in China have no air conditioning equipment, the mixer can't be controlled at a constant temperature, and the dough temperature needs to be controlled according to the seasonal changes. Therefore, the addition of yeast should be determined according to the following conditions: < P > 1. It is cold in spring, autumn and winter, so the yeast can be dissolved in warm water at about 35℃ first, which not only ensures the yeast to be evenly dispersed in the dough, but also can receive good fermentation effect. But the water temperature should not exceed 4℃, otherwise the yeast activity will be destroyed or killed.
2. In midsummer, when the room temperature exceeds 3℃, the mixer has no temperature control system. In order to control the excessive temperature of the dough, ice cubes are often added during the mixing. At this time, yeast should be added at the last stage of the dough mixing, and it can be dried and sprinkled on the dough to mix evenly.
3. In the process of stirring, yeast should be added to avoid direct contact with high osmotic pressure substances such as sugar and salt. Do not add yeast directly to high concentration sugar water or salt water.
4. If air conditioning equipment is installed in the bread workshop, and the indoor constant temperature is kept at about 25℃ all year round, both dry yeast and fresh yeast can be added in normal stirring and feeding order without activating in advance or delaying.
