Product introduction

Polyanionic Cellulose referred to as PAC, is made from natural cellulose by chemical modification and the obtained water-soluble cellulose ether derivatives, is an important water-soluble cellulose ether, its sodium salt is usually applied. Polyanionic Cellulose has good heat stability and salt tolerance, anti-bacterial and strong. The product is prepared with a good drop of fluid mud water loss, inhibition, higher temperature resistance. Widely used in oil drilling, especially offshore oil drilling wells and salt water.

Q:Types of food additives
General drinks containing pigment, potassium sorbate, etc .; jelly is not easy to eat; small snacks also contain a lot; the best Eat.
Q:Is soy dietary fiber a food additive?
No, soy dietary fiber is a kind of dietary fiber, in the classification, all the dietary fiber belongs to a can not be digested carbohydrates and carbohydrates in the classification of food raw materials, and flour, sugar, etc. belong to a Classification grade, does not belong to food additives.
Q:Where is there a place to sell food additives in OKorder?
To the new wholesale market, in the South Fifth Ring. There are a lot of additives stores, are relatively small. If you go to large, it is recommended to Xiaguang supermarket. You can ask the phone by 114, they have shops do wholesale, the variety is still full technical support.
Q:what is additive and subtractive colors?
Additive and subtractive colors has to do with color perception. Pigments (coloring in objects) reflect the color that you perceive. So for example a red square appears red because it predominantly reflects red light. If you took that pigment and mixed it with a blue pigment you get purple, if you add green pigment to that you would get a dark grey. Pigments are subtractive colors. But with light, if you take red light and blue light and combine them you get magenta light, and its brighter than either individual beam because you have twice the amount of light. If you were to add green light to that, you'd get white light and again it would be a brighter beam. Light is additive.
Q:What are the traditional cosmetics additives? What are the hazards?
Fungicide in the killing of harmful bacteria at the same time, it will kill the skin of the beneficial bacteria, so that the skin itself to resist the ability of external damage weakened, so that the skin's own protective function will be reduced.
Q:What are the disadvantages of eating food additives?
Hazards of Food Additives Summary Commonly used food pigments include two categories: natural pigments and synthetic pigments. Natural pigments come from natural, mainly extracted from plant tissue, and also include some pigments from animals and microbes. Synthetic pigment refers to the use of artificial chemical synthesis of organic pigment, mainly in coal tar separated from the aniline dye made of raw materials. In the long period of time food additive reporting process [2], because people do not recognize the harm of synthetic pigments, and synthetic pigments and natural pigments compared with a bright color, strong coloring, stable nature and low price advantages, Many countries generally use synthetic pigments in the food processing industry. With the development of society and the improvement of people's living standards, more and more people in the use of synthetic protein in food will not cause harm to human health problems. At the same time, a large number of research reports that almost all of the synthetic pigment can not provide nutrients to the human body, some synthetic pigment and even harm the health of the human body. When you eat fine snacks, fast food lunch, fragrant hot dogs, cast a glance at the exquisite packaging of food on the nutritional table, you will find that each food has additive ingredients. It is understood that the conversion of fat, refined cereal products, salt, high fructose syrup four components in the processing of food is the most common, these ingredients harm the human health.
Q:What are the food additives approved by our country?
By function is divided into 21 categories: acidity regulator, anti-caking agent, defoamer, antioxidant, bleach, bulking agent, gum base, coloring agent, coloring agent, emulsifier, enzyme preparation, flavor enhancer, Flour treatment agent, coating agent, moisture retention agent, nutrition enhancer, preservative, coagulant, sweetener, thickener, processing aid.
Q:Salt, white sugar is not a food additive?
Belong to, not all of the food additives are harmful to the human body. Those countries allow the addition of food modified preservatives can be eaten, no matter what kind of additives, even if it is harmful to the human body as long as the reasonable range is the human body Can only be resolved within the scope of no harm. Moreover, the state is also very important to this piece of food additives, and now there is a pure bio-type food additive polylysine, which is made of lysine polymerization, the main The role of preservative preservation, after eating by the human body is one of the eight essential amino acids, lysine, absolutely non-toxic side effects, you can rest assured that the use of food industry, especially now is the cusp when the anti-corrosion preservative must be careful Consider, must be qualified to the human body harmless additives will have a market, can do more long.
Q:Additive color mixing, or trichromatic?
Additive color theory states that RGB are the additive primaries and a mixture of these colors creates all other colors (this is in contrast to subtractive theory which uses CMY) Although RGB color space is mapped to the visual system via xyz colors, where the full circuit would be thus: RGB>xyz>x-bar,y-bar,z-bar>Yuv>RGB Our eyes actually work on a 2 channel binary system. This means that instead of having three channels of R-G-B (a component system) we have a channel for Red vs Green and a channel for Blue vs Yellow (an opposition) system. Bottom line: Since trichromatic theory includes yellow, it has to be the additive color mixing theory which, although archaic is still heavily used
