Types of additives and introduction

Sweeteners - commonly used artificial sweetener saccharin sodium,

sodium cyclamate. The purpose is to increase the sweetness sensation.
Preservatives - are commonly used sodium benzoate, potassium sorbate,

sulfur dioxide and lactic acid. For jams, preserves and other food

processing.
Spice - synthetic fragrances, but  WSD Metallic stearate also natural, flavor a lot. Consumers

eat chocolate all tastes, widely used in the production process of

various spices, it has a variety of unique flavors.
Coloring agents - commonly used synthetic pigment has carmine,

amaranth, lemon yellow, indigo and so on. It can change the appearance

of the food, it increased appetite.
Thickeners and stabilizers - can improve or stabilize the physical

properties of cold food, make food look smooth and delicate. They make

ice cream and other frozen food long-term organizational structure

soft, loose.
Nutritional supplements - can enhance and supplement certain

nutritional content of food. Such additives are a variety of vitamins,

amino acids, inorganic salts, etc., can make food food nutrition

fortifier meet different consumer needs. Such as various infant formula

to contain a variety of nutrition  WSD Plastic impact modifier enhancer, so milk to ensure the needs

of children of different ages on a variety of nutrition.
Antioxidants - can extend shelf life of food. Commonly used dimensions

C, C, etc. A different dimension.
Leavening agent - part of the candy and chocolate add leavening agent,

can contribute to ribosomes produce carbon dioxide, which play the role

of leavening. Leavening agents are WSD Aluminum hydroxide  commonly used sodium bicarbonate,

ammonium bicarbonate, composite leavening agent.
Sour agent - part drinks, candy and other sour agent often used to

regulate and improve the flavor effect. Common citric acid, tartaric

acid, malic acid, lactic acid and the like.
Brightener - benzoyl peroxide is the main ingredient of flour

brightener. China's food allowed in the flour to add maximum dose of

0.06g/kg. Brighteners exceeded, will destroy the nutritional flour

produced after acid hydrolysis may cause liver damage, benzoyl peroxide

in the EU and other developed countries has been banned as a food

additive. Green food production, processing, A grade, AA grade products

depending on the product itself or production needs, food additives can

be used in AA grade green food only allows the use of natural food

additives are not allowed to use synthetic chemical food additives, in

A grade green synthetic chemical can be used in food additives, in

green food production, in accordance with national standards and

reasonable use of additives, it is because, in addition to raw, fresh,

and can achieve commercial sterility of conditions of production,

storage, unpackaged food, processed foods have direct or indirect, more

or less use of food additives, the raw salt Take for example, our legal

elements in salt iodization, and adding iodine supplements, food

additives is in a class. So green food production enterprises,

especially the production and processing products.
Food additives to improve food quality and color, smell, taste, shape,

nutritional value, as well as the preservation and processing of food

needed to join in chemical synthesis or natural substances, green food

processing products, in production should be higher level, the rational

use of additives, developed a variety of varieties of products and

constant innovation to meet consumer needs, according to the current

food processing enterprise view of the problems reflected in the use of

food additives on the main The following two questions:
First, because the safety of food additives, misunderstanding, people

tend to think that natural than synthetic chemical food additive

safety, the actual toxicity of many natural products due to the current

detection methods, content detection limit, still can not make accurate

judgment, and, comparing the detected results had natural food additive

is not smaller than synthetic toxicity.

Environmental plasticizer selection and performance and characteristics

Environmental plasticizer selection:
Different design requirements of PVC products use different nature plasticized system, and the ideal plasticizer should meet the following requirements. 1, high plasticizing effect, good compatibility, low volatility.
2, migration resistance is small, with time shift delay products, or other materials do not migrate to the surface of the contact.
3, and good resistance to extraction, contact with products like oil or aqueous solvent, a plasticizer does not spread to occur.
4, good low temperature performance, low temperature without losing its products in flexibility. 5, good insulation properties. 6, good mechanical properties 7, odorless, colorless, non-toxic 8, good flame retardant properties. 9, anti-fungal properties. 10, low WSD Metallic stearate  prices. Plasticizing effect really Maoyou, plastic corporate trust products. A, name: chloromethoxy fatty acid ester. Second, the formula: C20H37CI3, a molecular weight of 463 Third, technical indicators 1, Appearance: pale yellow oily liquid. 2, density (20C) :1.155-1 .175 3, Flash Point: (open) ≥ 170 ℃ -195 ℃. 4, heating loss (125C ± 1C.3h)% ≤ 0.4. Fourth, the performance and characteristics of the product is the company under the guidance of experts, after years of painstaking research the success of a new type of plasticizer, which is made from natural oils and alcohol transesterification reaction, then the reaction of a class of chlorinated has a high molecular weight, good compatibility with PVC, excellent WSD Aluminum hydroxide  plasticizing effect, fire resistant, non-toxic, environmentally friendly compound plasticizers. Since both the product ester structure, octyl dimethyl substitution o stupid butyrate as a plasticizer, while containing chlorine can be replaced by paraffin, improve flame retardancy and electrical insulation.
Fifth, products and applications: Environmental plasticizer compatibility with PVC resin than DOP, DOA, DBP, and can be widely used in environmental protection pvc products, such as leather, PVC cable, plastic film, plastic sandals, foam sandals, doors and windows  WSD Stabilizers for pipe and window seals, PVC profiles, soft board, all kinds of soft, hard pipe, decorative materials, rigid foam board and all use of plasticizer products, has a wide range of uses, and ultimately to achieve lower production costs purposes.

The main difference between the two points of stearic acid and calcium stearate

Stearic acid are calcium stearate are salts. Salt meanings:
Refers to a salt of a metal ion or an ammonium ion (+ NH4) ion or a compound with a combination of non-metallic ions . Such as sodium chloride , calcium nitrate , ferrous sulfate, ammonium acetate and the like , such as calcium sulfate , copper chloride , sodium acetate , the salt is generally in the metathesis reaction product , such as sodium sulfate and sodium hydroxide , and water is generated , there are also other salts can be generated in the reaction , e.g., a substitution reaction . Solution of a soluble salt of a conductive , because the solution to be freely mobile ions , therefore can be used as an electrolyte. It would appear that calcium stearate containing metal ions on the calcium salt , literally you can see . Acid meaning:
The acid in solution chemistry is the ionization of hydrogen ions and cations can completely compound of purple red litmus test solution . In a narrow sense can be divided into inorganic acids, organic acids . Acid proton theory: acid is a substance capable of releasing a proton referred acids. Stearic acid is an organic acid , a certain acidity. Loss of hydrogen ions combine with calcium metal thing is calcium stearate . 1 , the appearance of nature
Stearic acid is a white or creamy -white powder or crystalline lumps, which has a cross-section of microstrip shiny fine needle crystals; similar grease micro odorless, tasteless. Calcium stearate is a white powder , insoluble in water , cold ethanol and ether, dissolved in hot benzene, turpentine , and other organic solvents. Slightly soluble in hot ethanol and ether. When heated to 400 ℃ slowly decomposed , flammable , met decomposition of stearic acid and corresponding calcium , hygroscopic . 2, use comparison: stearic acid cream and cream for skin care products from these two types of emulsion , so that it becomes a stable white paste. Stearic acid or manufacturing honey and almond milk the main raw material . Stearic acid esters in cosmetics, soap industry is more widely used. Calcium stearate heat stabilizers for PVC and other plastic processing lubricants , mold release agents and the like. In rigid products , and the base of lead salts , lead soap can increase the rate of gelation . Also used in food packaging, medical equipment and other requirements of non-toxic soft film and equipment. Can be made of polyethylene , polypropylene, halogen absorbers to eliminate the adverse effects of residual catalyst on the color and stability. As plasticizers in rubber processing , enabling natural rubber and synthetic rubber to soften the whole , and almost no effect on curing . Also used as polyolefin fibers and molded plastic lubricants , grease thickening agent, textile waterproofing agent, paint flatting agent , plasticizer manufacturing plastic labels and so on. Also used in pencil manufacturing and medicine, perfume industry .
