Is jelly solid or liquid, and what is jelly used for

It is colloidal, which has the same properties as our usual fish jelly, and it will melt when heated.

Colloids are characterized by the size of dispersed particles, and it is only a form of existence of substances, such as NaCl dissolved in water to form a solution, and if dispersed in alcohol, colloids can be formed.

There are many types of colloids, which can be divided into liquid, aerosol and solid sol according to different dispersants. The dispersant is liquid, called liquid sol, such as Fe(OH)3, AGI colloid; Dispersants are gaseous and are called aerosols, such as fog, clouds, smoke, etc.; Dispersants are solid and are called solid sols, such as smoky quartz, tinted glass, etc.

The nature of colloids.

1. Tyndall effect:

When a beam of light passes through the colloid, a shiny "pathway" is seen from the side.

2. Brownian motion:

The non-stop and disorderly movement of the colloids in the colloid belongs to the phenomenon of thermal motion of particles, which is not unique to colloids.

3. Electrophoresis phenomenon:

Under the action of the applied direct current electric field, the colloidal particles move directionally to the cathode or anode in the dispersant, which indicates that the colloids are charged (the colloids are electrically neutral).

4. Colloidal aggregation and precipitation:

The process of colloidal particles combining with each other to form large particles and precipitating under certain conditions is as follows:

1) Add electrolytes.

2) Heating 3) Add a colloid with an opposite charge to the particles.

ps.The landlord is interested in using a quick light to see if he can pass through the jelly, and if he can, it will meet the Tyndall effect, and he can prove that the jelly is colloidal.

Anyway, what I eat is solid, with a little water.

I think it's solid, because he's solidified!

Jelly is a food that is used to eat.

Jelly is a Western sweet, in a semi-solid form, made from edible gelatin.

Made with water, sugar and fruit juice. Also known as gel, it has a crystal clear appearance, bright color and soft taste. Jelly also contains pudding.

Classify. Yellow peach pulp jelly, peach pulp jelly, orange flavored jelly, orange pulp jelly, lemon flavored jelly cool, blueberry pulp jelly, juice jelly, grape flavored jelly cool, pineapple flavored jelly, mango flavored pudding, aloe vera lychee flavored coconut fruit.

Jelly, lychee pudding, apple-flavored jelly, assorted jelly, ......

Contraindications

Because the self-protection mechanism of young children's bodies is not complete, it is easy for jelly to enter the trachea or bronchi when eating jelly.

In the beginning, there were no such instructions on the jelly packaging, and later there were some accidents in which babies choked on jelly, and these instructions appeared on the jelly packaging one after another.

Children around 1 year old should not eat jelly, because children at this period still have few teeth, can not chew and crush jelly normally, once sucked in, block the glottis, and will suffocate to death in a few minutes. Because jelly is gelatinous, it is difficult to unclog even and requires surgery. Also, older children are advised not to eat jelly in a vaping mode, and it is better to bite into it or take it with a small spoon.

Jelly is a food that can be eaten and has a very tasty taste. Very fragrant and soft.

Jelly is a sweet tooth in semi-solid form. It is made with edible gelatin.

Sugar, made from fruit juice. Jelly is made of water, sugar or starch sugar as the main raw material, supplemented by food additives such as thickeners.

Glued food processed by solsoling, blending, filling, sterilization, cooling and other processes with or without fruit and vegetable products, milk and dairy products.

Preparation of jelly liquid

The preparation method of jelly liquid is relatively simple, generally soaking gelatin first, then melting in water, and then adding the required ingredients, that is, mixing into jelly liquid. The preparation method of jelly liquid depends on the different coagulation raw materials used, and there are two common ones: using jelly powder or gelatin.

Using jelly powder to prepare jelly liquidUsing jelly powder to prepare jelly is the most convenient and time-saving method. This is because all the solidified raw material jelly powder is prepared and sterilized in the factory, and then dried and packaged for the market. Users only need to follow the instructions and dosage ratio table on the product packaging, which is very convenient to use.

Jelly is a Western sweet in semi-solid form and is made from edible gelatin with water, sugar, fruit juice.

Also known as spicy, it has a crystal clear appearance, bright color and smooth taste. Jelly is a delicious food made of water, sugar, carrageenan, konjac flour, etc. as the main raw materials, through sol, blending, filling, sterilization, cooling and other processes. Carrageenan, also known as carrageenan, carrageenan, is a natural polysaccharide colloidal extracted from natural unicorn and other seaweeds, all of which have the basic characteristics of soluble dietary fiber, which is a safe thickener approved for use in various foods in China.

Jelly is a kind of sweet, transparent, soft and sweet taste, mainly made of edible gelatin, water, sugar and fruit juice, deeply loved by the public, jelly varieties are very numerous, according to the content can be divided into fruity type, juice type, pulp type, milk-containing type and other types, and according to the type of gel type, can be sucked two types.

Jelly is something.

1. Variety introduction.

Jelly, also known as gel, is a kind of sweet, because the main ingredient is edible gelatin, so it is transparent, soft and smooth, sweet, more popular with the public, has become a common snack on the market.

2. Main classifications.

Jelly is divided into two types according to the type, namely gel type, absorbable type, gel type jelly is mostly packed in bowls or boxes, and suckable type is packed in bags, jelly can be divided into five types according to the contents, namely fruity type, juice type, pulp type, milk-containing type, and other types.

3. Precautions.

Jelly is relatively soft, people with bad teeth can also eat, but the elderly and children under one year old can not eat more, so as not to consume too much sugar can not be absorbed, affecting physical health, and children under one year old have poor chewing ability, and are prone to suffocation when eating jelly.

Jelly is colloidal, and most of the jellies used are algin. This is a natural food additive, nutritionally, called soluble dietary fiber. The colloids of jelly are formed by boiling carrageenan and manna gum mixed with sugar and cooling and condensation, and the amount of these two substances added to the jelly is.

Colloid: Colloid, also known as colloidal dispersion, is a relatively homogeneous mixture, in which the colloid contains two different states of substance, one dispersed phase and the other continuous phase. A part of the disperse is composed of tiny particles or droplets, and the dispersion system of the disperse particles with a diameter of 1 100 nm is colloidal; Colloids are a kind of dispersion systems with a diameter of dispersed particles between the coarse dispersion system and the solution, which is a highly dispersed multiphase heterogeneous system.
