| Physical and Chemical Properties | White to light yellowish brown free-flowing powder. Close to odorless. It can be dispersed in hot or cold water to form viscous liquid, and the viscosity of 1% aqueous solution is about 4 ~ 5Pa?S, which is the highest viscosity in natural rubber. Adding a small amount of sodium tetraborate turns into a gel. After being dispersed in cold water for about 2h, the viscosity showed strong viscosity, and then gradually increased, reaching the highest point at 24h. The viscosity is 5~8 times that of starch paste. Heating quickly reaches the highest viscosity. The aqueous solution is neutral. The viscosity of pH 6~8 is the highest, and the pH value above 10 decreases rapidly. With the decrease of pH value in the range of 6.0~3.5, the viscosity also decreases. The viscosity increases below the pH value 3.5. |

burtonitev-7-e - Introduction
Soybean oligopeptide is a mixed peptide product composed of 2-6 amino acids and with a molecular weight of 200-800Dalton. Compared with the original protein, soybean oligopeptides have good water solubility, water retention and foaming properties, and can be completely dissolved under any pH2-10 acid and alkali conditions. Soybean oligopeptides can be completely dissolved with other food ingredients and maintain their original physical, chemical and nutritional characteristics.

| Overview | guar gum is a plant gum that can be extracted from carob fruits and guar beans. Carob is a perennial shrub that mainly grows along the Mediterranean coast, and guar is an annual legume that mainly grows in desert-like areas such as India, Pakistan, and Texas, USA, it is suitable for growing in areas with large temperature difference between day and night and sufficient rain. The guar gum currently used is basically extracted from guar beans. After the mature guar is peeled, it is sent to a grinding processing plant, and the guar is separated into endosperm flakes, germ and bark by thermochemical treatment. The germ is often used as an animal feed with a high protein content. Endosperm flakes are processed into guar gum in a grinding process. |
| structural characteristics | guar gum is a Mannan-pyranose unit as the skeleton to form the main chain, every two Mannan-pyranose units have 1,6-linked galactopyranose units as side chains. Since guar gum has a structure similar to cellulose, it can rapidly adsorb on the fiber surface and provide a large amount of hydroxyl groups for forming hydrogen bonds between fibers, thereby effectively promoting the bonding between fibers. In addition, guar gum can also improve the retention of fillers and fine fibers, and can also avoid the poor aggregation between fibers, improve paper uniformity. |
| physiological function | soybean oligopeptides are prepared by hydrolyzing soybean protein, short-chain polypeptides consisting mainly of 2-10 amino acids and a small amount of free amino acids. The average relative molecular mass was 1000-20000. Physiological function: ① lower blood pressure. ②Lower blood lipid. ③ regulation of blood glucose. (4) it is suitable for nutritional supplements after surgery, especially in the recovery period of gastrointestinal surgery and the period of gastrointestinal dysfunction caused by high temperature and overwork, as well as in the period of weak digestive function of infants and the elderly. It is also suitable for use as an energy supplement for athletes. (5) it can promote the proliferation of intestinal Bifidobacterium and lactic acid bacteria, and has the function of regulating the stomach and intestines. The removal of free radicals in the body, anti-aging. The role of a certain weight loss. |
| Product Performance | guar gum has been an effective additive for paper making, which can be classified into pulp addition, surface sizing and guar for coating. Adding guar gum in the slurry has the following advantages: 1) improving the tensile strength of paper; 2) improving the surface strength and improving the printability; 3) improving the retention rate of fillers and fine fibers; 4) to improve the uniformity of the paper, guar gum to micro-flocculation way to improve the filter performance of the paper machine network, the paper will not be destroyed; 5) reduce the difference between the two sides of the paper; to improve the interlayer bonding strength of paperboard. Guar gum for surface sizing, the improvement of the surface properties of the paper is particularly obvious: 1) can improve the surface strength of the paper, improve the printability, and do not affect the air permeability of the paper; 2) improve the oil resistance and solvent resistance; 3) improve the stability of the surface sizing liquid; 4) can improve the coating performance; 5) improve the lipophilicity of the paper surface. For the coating of guar gum, can improve the performance of the coating: 6) to improve the water retention of the coating; 7) to improve the rheology of the coating. |
| Application | 1. Biological immobilization carrier material: guar gum can be used for the preparation of immobilized tyrosinase biofilm. 2. Application in the field of drug controlled release: guar gum is a natural polymer of galactomannan, which is degraded only by bacteria in the colon and is an important candidate material for targeted Colon drug delivery carrier, however, its high water solubility and expansibility lead to intragastric release of the drug, which limits its application. 3. Application in fisheries and environmental protection: guar gum as a binder added to feed significantly enhances the stability and mechanical strength of fish manure particles, facilitates the timely cleaning of manure, and reduces the harm to fish. |
| preparation of | guar gum from the seeds of guar seeds to remove the embryo after the endosperm part is cleaned, dried and crushed after adding water, after pressure hydrolysis, it was precipitated with 20% ethanol, centrifuged, dried and pulverized. Commercial glue is generally white to light yellow-brown free flowing powder, close to no smell, no other odor, generally containing 75% ~ 85% polysaccharide, 5%~ 6% protein, 2% to 3% of fiber and 1% of ash. |
| Storage Conditions | guar gum should be kept in a dry, ventilated, cool place and protected from moisture. |
| Use | 1. Food grade: frozen food: anti-ice slag production, increase the stability of freezing. Baked Food: maintain humidity, improve texture. Beverage: improved taste, stable suspension of particles. Salad dressing: thickener, alternative to oil. Cheese and cream: into the texture. Cooked meat food: maintain water Juice, increase the oily feeling. Meat Food: replace the fat oil composition. Keep moisture.
