Is it okay to use mineral water to make bird s nest, and does bird s nest have to use purified water

OK. Bird's nest is simmered in a stew pot with water and the center temperature of the stew cup is about 80 degrees Celsius, which maintains the main nutrients of bird's nest, sialic acid and collagen.

Does not break down denatured. Stewing over water means that in a steamer or saucepan, after adding water, use a stainless steel rack to make the bowl or cup on the shelf, and the bowl or cup does not directly touch the water.

Preparation of bird's nest:

1. Soak swiftlet's nest for 2 hours, and change the water several times halfway;

2. Tear it open after soaking soft;

5. Pour into a bowl and add 70% of the water;

6. Simmer for 30 minutes;

7. Pure bird's nest is better with oat milk, and a bowl of bird's nest can be eaten 2-3 times.

Of course, it is good to make bird's nest with mineral water.

It is better to use purified water or cold boiled water for stewed bird's nest, because the water quality is different in various places, and the tap water in some places will be mixed with bleaching powder, so do not choose tap water for stewed bird's nest.

Bird's nest is generally stewed in a stew pot with water barriers, and the temperature of the center of the stew pot is about 80 degrees Celsius to keep the main nutrients of bird's nest, sialic acid and collagen, from decomposing and denaturing.

Bird's nest stew method.

1. Preliminary soaking: Soak one piece of bird's nest (about 6g) in water each time. After about 1-2 hours, if there are small stray feathers of swallows in the water, pick them clean.

2. Deep soaking: Pour out the water from the previous step and replace it with about 300g of pure water or mineral water (because the chlorine in the tap water has a strong oxidizing effect and will destroy the nutrition of the bird's nest), and soak the bird's nest for 6-8 hours. After the bird's nest is fully soaked, divide it into small strips along the texture of the bird's nest.

3. Pour the above-mentioned soaked and torn bird's nest into the stew pot together with the water used for soaking (if you don't have it, you can also use a ceramic bowl at home instead, it is better to have a lid). Be careful not to pour too full, the bird's nest will grow up when stewed. Cover the pot, bring the water to a boil and turn to low heat for about 1 hour.

This method avoids excessive heating of the bird's nest, and the temperature of around 80 degrees retains the activity of its protein.

It is best to use purified water and filtered water instead of mineral water and tap water to stew bird's nest.

Mineral water: water containing a certain amount of mineral salts such as calcium, potassium, magnesium, sodium, strontium, metasilicic acid, etc. Mineral water is hard water and is not suitable for stewing bird's nest, which will affect the taste of bird's nest. Soaking bird's nest in mineral water will also cause the bird's nest to soak slowly, and the bird's nest silk will be stiff and not soft.

Tap water: The taste of bleach powder in tap water is too strong, which affects the taste and texture of bird's nest and will affect the nutrition of bird's nest.

Purified water: water made by electrodialyzer, ion exchanger, reverse osmosis, distillation and other appropriate processing methods, and does not contain any minerals. It is soft water.

To sum up, it is best to use purified water, filtered water, and less mineral water and tap water for stewed bird's nest.

The traceability of Bird's Nest is soaked with water, and the soaking rate often reaches 7 times or more, and the taste and effect of the bird's nest are naturally very good! Of course, if you are lazy to stew, you can also choose Dr. Yan's instant bird's nest!

Of course, it's natural mineral water There is nothing in pure water, natural mineral water is the best quality, like Nolan natural mineral water is a good choice.

Although it is confirmed that the demand curve arises naturally from the theory of consumer choice, the derivation of the demand curve itself is not a theory that proposes consumer behavior. Simply determining how people react to change doesn't require a rigorous analytical framework. However, consumer choice theory is extremely useful.

As we will illustrate in the next section, we can use this theory to more deeply determine the factors that determine family behavior.

Instant Answer Draw budget constraint lines and indifference curves for Pepsi and pizza. Illustrate what happens to the budget constraint line and consumer optimum when pizza** rises. Use your graph to divide this change into income effects and substitution effects.

Four applications. Now that we've established the basic theory of consumer choice, we can now use it to illustrate four questions about how the economy works. However, since each problem involves family decision-making, we can address these issues with the consumer behavior model we just proposed.

Are all demand curves sloping to the bottom right?

In general, when an item** goes up, people buy less. Chapter 4 refers to this normal behavior as the law of demand. This pattern manifests itself in the demand curve sloping to the lower right.

However, as far as economic theory is concerned, the demand curve also sometimes slopes to the upper right. In other words, consumers sometimes defy the law of demand and buy more when one item rises. To illustrate how this can happen, look at Figure 21-12.

In this example, the consumer buys two items – meat and potatoes. Initially, the consumer budget constraint line was a straight line from A to B. The best advantage is c.

When the potato ** rises, the budget constraint line moves inward and is now a straight line from A to D. Now the best thing is e. It is important to note that the rise in potatoes has led consumers to buy more potatoes.

1. Bird's nest is soaked in warm or cold water. Bird's nest needs to be soaked, cleaned and steamed before it can be eaten, and soaking is very important as the first step. During the entire soaking period of bird's nest, choosing water is the most important step, and it is also the most easily overlooked.

Here we mainly introduce two soaking methods, namely warm water soaking and cold water soaking.

2. Warm water here refers to pure water at room temperature, not tap water or mineral water, because both are hard water, experiments have shown that the expansion rate of stewed bird's nest in mineral water is 3 4 times, far lower than the expansion rate of 7 8 times of pure water, and it also affects the soft and slippery feeling of eating bird's nest, so for the consumption of bird's nest, try to choose pure water. Before soaking, choose the container that can be submerged in the bird's nest after adding water, put in the bird's nest, add an appropriate amount of pure water, and soak it at room temperature, this method is the most commonly used and convenient method, which is more suitable for spring and autumn, when the temperature is 20 30.

No, you can use tap water when soaking and making, and you can choose pure water if you have the water quality requirements.

Preparation: Bird's nest, rock sugar, wolfberry to taste.

Production method: 1. Soak the bird's nest in clean water (more than three hours) and tear it into strips along the texture.

2. Drain the bird's nest and put it in a stew pot, pour in an appropriate amount of water to cover the bird's nest.

3. Put the stew pot into the pot, add water to the pot to half the height of the stew pot, bring to a boil over high heat, turn to low heat and simmer for an hour.

4. Add rock sugar and continue to simmer for about half an hour.

5. Pour the finished bird's nest into a container, sprinkle with wolfberries to garnish, and eat it directly.

No. In the process of soaking, the dust and bacteria on the surface of the dried bird's nest will be dissolved into the soaked water, and a certain amount of bacteria will breed when soaking, and the naked eye can not distinguish how many bacteria, if the bird's nest is stewed together with the water when boiling, the water quality can not be ensured to be clean, and the stewing may not reach the sterilization boiling point, such as the water quality is not clean when eaten may be harmful to health. <

No. In the process of soaking, the dust and bacteria on the surface of the dried bird's nest will be dissolved into the soaked water, and a certain amount of bacteria will breed when soaking, and the meat can not see how many bacteria, if the bird's nest is stewed together with the water when boiling, the water quality can not be ensured, and the stewing may not reach the sterilization boiling point.

You can use natural water for honey bird's nest, but it is not recommended to use it, honey bird's nest is recommended not to use tap water, it is best to choose *** pure water, do not use tap water and cenote water. Because the tap water from rivers, lakes and seas has been processed and disinfected, there are a large number of impurities and chlorate and other chemicals in it, which is not conducive to the absorption of bird's nest; The well water contains more calcium and magnesium ions, so the hardness is relatively large. We use a large bowl or a deep porcelain plate, take 2 pieces of bird's nest Weixiang and put them in the bowl, pour in an appropriate amount of pure water, and the amount of water is not more than the bird's nest just put in.
