Pectin has always been a natural part of human diet. It is a safe and non-toxic natural food additive recommended by the FAO/WHO Joint Committee on Food Additives. There is no daily limit on the amount of pectin added. Pectin has many functions. For example, pectin, as a natural vegetable colloid, can be widely used in the food industry as a gelling agent, stabilizer, tissue forming agent, emulsifier and thickener. Pectin is also a water-soluble dietary fiber, which has the function of enhancing gastrointestinal peristalsis and promoting nutrient absorption.
It has a good effect on the prevention and treatment of diarrhea, colon cancer, diabetes, obesity and other diseases, and is an excellent matrix for drug preparation. At the same time, pectin is a good heavy metal adsorbent, because the molecular chain of pectin can form an “egg box” like network structure with high price metal ions, so that pectin has a good adsorption function of heavy metals. In addition, pectin has film forming properties, good water retention and radiation resistance.
The application of LM pectin manufacturer
Pectin is used in the food industry as a food additive or ingredient, and it mainly plays a role in gelling, thickening, improving texture, emulsifying and stabilizing. The solid content needs to be less than 60% of the product, and the product needs to contain calcium ions or other metal ions, so that the gel will eventually form. The use condition of low-ester pectin is that the pH of the system is 2.6～6.8, the solid content is higher than 10%, and calcium ions are required (at least 15mg/g pectin). It is mainly used for low-sugar jam, yogurt pulp base, soft candy , Sweets, bakery products, glazing, etc.
(1) Yogurt products
In the production process of yogurt, different kinds of pectin have different functions. For example, adding low methoxy pectin can prevent whey release. In the process of making yogurt, it is necessary to strictly control the dosage of pectin. Once sufficient amount of additives are not added, the charge will be neutralized and the repulsion force will disappear. The structure of dairy products can not be stable, so the structure of acidic dairy products can only be kept stable after the addition of new repulsion force.
(2) Jam
If there is too little pectin in the raw material when making jam, you can take advantage of the thickening effect of pectin and use 0.20% pectin as thickener. The usage of pectin in low-sugar jam is about 0.60%. The recipe of low-sugar strawberry jam is 50.00% strawberries, 36.00% sugar, 13.00% water, 0.60% amidated low methoxy pectin and 0.40% citric acid. In the strawberry jam recipe above, amideated low-methoxy-pectin or methoxy-pectin can be used, since there is a certain amount of calcium in the fruit and water, so calcium salts are not needed.
(3) Bread
Because the dough with pectin is more malleable, the baking volume of the bread increases. For example, in hamburger making, if the size of the hamburger is kept the same, adding pectin reduces the amount of flour used to make the same size hamburger by 30 percent. In addition, bread made with pectin added dough can prolong the selling time of bread.
(4) Drinks
As people pay more attention to healthy diet, low-sugar drinks have become more and more popular in the market. However, the taste of drinks decreases with the decrease of sweetness. In this regard, low methoxyl pectin can be added to enhance the taste of the drink. Add it to contain the fruit drinks, it can be generated and calcium gel reaction, thus reducing due to pulp precipitation hard material, make pulp evenly suspended in the beverage, also can improve the taste of fruit juice, not only overcome the difference of pseudoplastic of sodium alginate, shortcomings and so on rubber smell, turbidity, also have good and contact with health care function of lead poisoning.
(5) Application in health care
Pectin is a valuable water-soluble dietary fiber. Pectin has the functions of lowering blood fat, lowering cholesterol, anti-radiation, adsorbing heavy metal ions, moistening the intestines, and anti-cancer. At present, there are products that use pectin in domestic medicines and health products, such as pectin, a gastric medicine for moisturizing and laxative, to remove heavy metal lead in the body, etc. However, the current demand for the amount of pectin is still not very big.
Different from other dietary fibers, the structural properties of pectin make it have good water solubility, high viscosity, can absorb heavy metals and other cations and toxins, promote gastrointestinal peristalsis, and can be fermented by the intestinal flora in the large intestine. Chain fatty acids lower the pH of the intestinal tract, kill harmful bacteria, and promote the proliferation of beneficial bacteria. Studies have also shown that pectin can play a role in preventing cancer.
(6) Other applications
In addition, pectin can be used in plastic wrap, diapers, cosmetics and toothpaste
