How do you make the powder?

Tool diagram. Raw material of powder pulp. Mix the three kinds of powder and pour into the water. Stir well with a spoon. Stir until the powder is free of particles. Brush the plate with the right amount of oil. Dig the powder and pour in, just cover the baking pan, should not be thick, shake evenly.

Ingredients: 100 grams of old rice, 350 grams of water, 50 grams of corn starch, 20 grams of sweet potato starch, 50 grams of flour.

Pour sticky rice noodles into a large bowl and add corn starch. Add cassava starch and pour 200 grams of cold water. Stir into a uniform powder. Stir while flushing 210 grams of 80 degrees hot water. History: vermicelli noodles originated in Fangcheng County, Henan Province. at that time, it was famous for pea noodles with a long history.

When making pulp, soak the mung beans or peas in water, expand and grind them on a stone mill to make a coarse pulp, filter the residue with gauze, and then put it in a basin or jar. After a day or two, the pulp water ferments and turns sour.

How to cook starch size

Starch gelatinization and hydrolysis weighed 100g starch in 500mL triangle flask, added water 200mL, stirred evenly, adjusted pH to 2: 3 with 5%Na2CO3, added 2mL5%CaCl2 solution, heated in 90-95 ℃ water bath and stirred continuously, starch paste gradually gelatinized and completely.

As the water temperature rises, the slurry will slowly thicken and ripen, roll out the bubbles and boil for another minute. At this time, the paste becomes white and paste, and a little paste on the hand feels sticky. at this time, add cold boiled water on the surface of the paste, seal and store. This is one of the methods of cooking pulp.

Then pour the stirred starch solution into the pot, turn on a small fire and keep stirring with a shovel. Remember to keep stirring over low heat, so as not to burn the solution. The dissolved starch will evaporate with the moisture, and the consistency of the flour will become more and more sticky until it is boiled into a paste and can be out of the pot.

Question 1: how do you do the paste? It's easy to make paste. Starch should be used to make paste (preferably cassava starch). First mix the starch with cold water until there are no particles. Put in more water, otherwise it will be too thick to use. Then cook on the stove and stir until the paste is cooked.

There are two methods for making starch pulp: boiling method and pulping method. In the boiling method, the starch is mixed with full amount of cold water, and then heated and stirred in a sandwich container to make gelatinization; in the pulping method, the starch is mixed with a small amount of warm water and then washed into a certain amount of boiling water (or steam), and then gelatinized.

Specifically, pulping is made by suspending starch in a small amount (1-5 times) of water, then pouring into a certain amount of boiling water according to the concentration requirements, and constantly stirring and gelatinizing; cooking is mixing starch in all amount of water, heating and stirring constantly in a sandwich container (not heated by direct fire to avoid coking) until gelatinization.

How to make starch paste (boil starch paste)

How to make paste by yourself

Materials / tools needed to make paste: water, bowl, flour, sugar. First of all, we need to prepare the materials. Here, the materials we need are made of water, bowls, flour and sugar, as shown in the following picture. Then, stir the flour and sugar in a pot and mix the flour and sugar with a stirring stick until well stirred, as shown in the image below.

The steps are as follows: boil the rice into porridge with water, not too much water, at least 30 minutes, otherwise the viscosity is not good. Boil the porridge until it is sticky, as shown in the picture. Put the porridge to cool. Pour the porridge into a sieve and stir hard. It's paste when it's cool in the shade or in the refrigerator.

Add water to the pot (you can use any pot or pot) and bring the water to a boil over high fire. The batter that has been stirred in advance will be washed into the pot and stirred evenly. The flour paste of good quality should not have a pimple. Continue to boil the paste water, and the homemade paste will be ready, put it in a jar and take as you like.

How to prepare 10% starch solution for viscosity is edible corn starch.

1. Mixing: first add 600 kg of water to the reaction pot, and then add 56 kg of sodium hypochlorite under continuous stirring (the available chlorine content is 8%). Then add 200kg of corn starch under stirring and stir well. Then 45 grams of nickel sulfate was added under stirring and the pre-prepared concentration was 0.5 minutes to make the above materials disperse evenly.

2. Sodium hypochlorite method: first, 600 kg of water is added to the reaction pot, and 56 kg of sodium hypochlorite is added under continuous stirring (the available chlorine content is 8%). Continue to stir, after fully dissolving, add 200 kg of starch and stir well.

3, the general sds solution is the mass volume ratio (w / v), 10% is 10 grams of sds powder dissolved in water, fixed volume to 100ml. Sds dissolves slowly can be 37 degrees water bath for an hour, do not shake too violently, there will be a lot of bubbles.

4. The preparation method of soluble starch solution is as follows: weighing: weighing a certain amount of soluble starch, the general amount required is 0.5g. Dissolve: mix the soluble starch with the right amount of distilled water and stir well until the starch is completely dissolved.

5. I tried, about every 100 milliliters of water mixed with 130 cubic centimeters of starch, stirring hard with spoons and the like, it is very difficult to stir. But insist, after stirring, you can gently hit the liquid surface with the convex surface of the spoon, if it does not splash out, it will be successful. But the mouth of the container must be big so that you can play.

How to make starch paste

Add 15 grams of starch to a small pot, add an appropriate amount of hot water and stir until completely dissolved. Dry the dissolved starch to room temperature, add 100ml water and stir well.

Washing powder is to purify starch and remove impurities from flour.

Place 100g starch in 400ml beaker, add 200ml water, stir evenly, mix starch paste, adjust pH=2-3 with 5% Na2CO3, add 2ml 5%CaCL2 solution, heat in water bath at 90-95 degrees Celsius, and stir constantly, starch paste from beginning to complete paste.

The production method is to marinate the raw materials with seasoning and then mix them with water and starch for sizing. The consistency of the pulp should be able to wrap around the raw material. The material standard is generally: the ratio of dry starch to water is 1 ∶ 2.

How is the powder made?

To make sour, first choose fresh mung beans, thoroughly bubble, then add water to grind into mung bean milk. Then the viscosity of the suspension is moderately increased by acid pulp, so that the fine starch floats on the upper layer, and the starch can be taken out to make mung bean cold powder. The suspension in the middle is acid pulp. Sour pulp is generally sour, slightly bitter, with a slight sour smell.

The main materials of dry powder pulp are starch and water. The production method is to marinate the raw materials with seasoning and then mix them with water and starch for sizing. The consistency of the pulp should be able to wrap around the raw material. The material standard is generally: the ratio of dry starch to water is 1 ∶ 2.
