There are several types of yeast: 1 fresh yeast 2 sugar-containing dry yeast 3 sugar-free dry yeast Solution 1: dough with sugar and fresh yeast, natural proofing can be divided for 30 minutes at room temperature 28-30 °, and natural proofing can be performed for 50 minutes after formingYou can bake from left to right, and spray water in the middle.

Solution 2: The dough contains sugar and sugar-containing dry yeast, and it can be divided for 30-40 minutes when it is naturally proofed at room temperature 28-30 °.

After shaping, it can be roasted naturally for about 80 minutes. Pay attention to water spray in the middle.

Solution 3: The dough contains sugar and sugar-free dry yeast, and it can be divided into 50-70 minutes when it is naturally proofed at room temperature 28-30 °, and it can be baked after it has been proofed for more than 90 minutes. It should be sprayed with water in the middle.

General fermentation temperature is 35 ℃?

The best way is to observe it every 4 hours after 5 to 5 hours. If there are small pores, it means that it has been fermented.There will be experience.

As the fermentation environment is affected by temperature and humidity, it is more important to arrange a bowl of hot boiling water for antique fermentation in an oven (or a confined space such as a microwave oven). The fermentation time is 40-60 minutes as the ambition, depending on the dough fermentation.Degree.

In winter, due to the rise in temperature, the undestructive mold is fermenting, which can increase the amount of yeast, change the hot water during the secondary fermentation, or increase the heat to ensure a certain temperature and humidity.

If you are more confident about the temperature of the oven, you can adjust the temperature to 30-40 degrees. Antique sponsored fermentation.

In addition, the toast bread is not fermented in place, probably due to insufficient flour strength or kneading to the complete stage.

Eating cocks is more likely to reduce the estrogen and progesterone concentrations in the blood of the parturient mother after childbirth, which is conducive to the role of prolactin to promote the formation of milk.

The ovaries and egg coats of hens contain a certain amount of estrogen, which reduces the effectiveness of converting maternal prolactin and affects lactation.

The male retinal pill contains androgen, which has an anti-estrogen effect.

Therefore, if you eat a stewed big rooster (also called Marumaru together) after birth, it will undoubtedly increase the maternal milk.

With the exception of roosters, which are beneficial to both mother and child, it also helps the mother to maintain a better figure during breastfeeding.

However, in some cases, when the nipples are improper, that is, the breasts are swollen and there is no milk, do not eat cocks and milk, otherwise it will cause mastitis.

Eating stewed hens after opening milk is more beneficial for hens to have blood, but it is not advisable to eat old hens one week after delivery. This is because prolactin will be promoted because the concentration of estrogen and progesterone in the blood is greatly reduced after deliveryEffect of lactation, promote milk secretion.

However, postpartum stewed old hens, because the hen’s ovaries and egg coats contain a certain amount of estrogen, so the concentration of estrogen in the blood increases, and the effectiveness of prolactin decreases, which leads to insufficient milk and even complete milk return.
However, after the mother has opened the milk, it is best to eat the stewed hens about 10 days after the birth.

The hen’s protein content is relatively high, there are many types, and the digestibility is high, it can be easily absorbed and utilized by the human body, which has the effect of strengthening physical strength and strengthening the body.

The hens contain phospholipids that have an important effect on human growth and development, and are one of the important sources of phospholipids in the precipitation structure of Chinese people.

The hen has good therapeutic effects on malnutrition, chills and cold, fatigue, fatigue, irregular menstruation, anemia, and weakness.

[Which oil is suitable for frying

[Which oil is suitable for frying

There are many types of fried foods, such as fried dough sticks, meatballs, onion cakes, etc. are more common fried foods, and many people like to eat fried foods for breakfast. Some people think that fried foods areVery delicious, although it is delicious but not suitable to eat more. In fact, it is not good to fry. The oil used is very important. There are many types of oil. Some cooking oils are not suitable for frying. What is the best fried thing?How about?
What is the best fried thing?
Peanut oil is the most stable at higher temperatures than other cooking oils because of its unsaturated fatty acids, and it is least susceptible to denaturation or decomposition when fried, resulting in harmful substances.
So peanut fried things are the healthiest.
And peanut oil has a unique aroma of peanuts, the fried thing is very attractive.
Palm oil Palm oil is mainly used for fried instant noodles.
Because there are many saturated fatty acids, it is not easy to deteriorate.
However, the freezing point temperature is relatively high, and the single palm oil at room temperature in autumn and winter in China has solidified.
The oil temperature has a high smoke point, 235 degrees, so it is particularly good for frying.
Lard is one of the standard oils for Chinese food, and it is divided into suet oil, fat, and back oil.
If you pay attention, many Chinese foods must be made with lard.
Chinese dim sum crisping with lard is the right way.
Especially the flatbread, lard goes well with onion and flour.
In many shops specializing in fried foods, lard is added to the frying oil, which generally accounts for 30%. In order to effectively increase the flavor, the fried things have a golden color and crispy taste.
But the lard ratio should not be too high, otherwise it will be very greasy when it is cold.
Coconut oil Coconut oil is extracted from the white flesh of coconut and contains almost 50% lauric acid, a healthy saturated fatty acid.
It will become solid at room temperature, so it is not suitable for salads, but because of its high smoke point, it is an ideal cooking oil.
The principle of fried food The smoke point and melting point of the oil determine the cooking method, the unsaturated fatty acids determine the health of the oil, and the aromatic organic matter dissolved in the oil determines the flavor of the oil.
The same material uses different processing techniques, contains different ingredients, and has different applicability.
Fried foods are mainly cooked using oil as a heat transfer medium. The temperature for low-temperature frying (55 to 60% oil temperature) is about 130 ° C to 170 ° C, and the high-temperature frying (70 to 80% oil temperature) is about 170 ° C.To 230 ° C, so the smoke point of frying oil is generally higher than 230 ° C.
Theoretically, the higher the smoke point, the more suitable for frying, so that during the frying process, not too many harmful substances will be generated.
Several Factors Affecting Frying Oil 1.
Considering the oxidation speed —- due to the different fatty acids contained in fats and oils, the difference in oxidation speed is relatively large, the saturated fat has the highest stability, and it is the least susceptible to oxidation.
The higher the degree of saturation used in frying food fats, the less likely it is to be oxidized, and the less lipid peroxides are produced.
Therefore, the fat used for frying food is preferably saturated fatty acid.
Palm oil> Animal oil> Olive oil, wild tea oil> Peanut oil> Corn oil> Soy oil> Rapeseed oil> Thresh seed oil, flax oil, etc.
Considering the stability of fat —- relatively stable oils such as butter and cocoa butter in natural oils have a stability value of 2.
4, followed by lard and palm oil, with a stable value of 1.
0, the stability of peanut oil in vegetable oil is better, the stability value is 1.
2. Other oils are 1.
0 or 1.
Below 0, such as soybean oil, sunflower oil, etc.
Fats with low stability values are not suitable as frying oils.
The soybean oil and rapeseed oil mentioned above are not suitable for frying oil because they contain a certain amount of linolenic acid.The linoleic acid vegetable oil above is not suitable for frying oil, such as safflower oil, sunflower oil pointed at linoleic acid, the same will accelerate the oxidation reaction at high temperature, and produce peroxides and trans fatty acids harmful to health.
