Everyone knows that calcium is the most natural way to get food. However, many dietary recommendations often overlook important requirements: calcium supplements must be easy to buy and not expensive; the amount of food eaten each day should be large enough to eat more without harm; calcium can be effectively digested; This kind of food must be easy to eat and taste good. Therefore, foods high in calcium may not be the best source of calcium supplements. So, what foods can satisfy these "harsh" requirements? 1, fruits and vegetables - leeks, canola Many green leafy dishes are not inferior to the effect of calcium supplementation. The calcium content of leeks and canola is higher than the same weight of milk. In addition, vegetables contain a lot of mineral elements and Vitamin K that help calcium absorption. When vegetables are boiled over and cooked again, the absorption rate of calcium will be better. 2, fish - muddy At the same weight, the calcium content of loach is nearly 6 times that of squid and about 10 times that of squid. Mud burned tofu combines muddy and tofu with calcium-rich ingredients and is definitely a calcium supplement. 3, seasoning - sesame paste After digesting sesame into sesame, the digestibility is greatly improved. Eat a big spoonful of sesame (about 25 grams), which contains about 200 milligrams of calcium. Sesame sauce can be used as a cold dish sauce and mutton seasoning sauce. It is also used in rolls, pancakes, fire and other noodles. 4, cereals - oats Among various cereals, oats have the highest calcium content, which is 7.5 times greater than that of polished white rice. Although the calcium absorption rate in oats is not as good as calcium in milk, it is still beneficial for preventing calcium deficiency. If you mix oatmeal and black sesame into a delicious congee, you will have better calcium supplements. 5, soy products - dried bean curd After the dried bean curd is pressed and concentrated, the calcium content is outstanding in soy products. For example, the calcium content of Xiaoxianggan can be as much as 7 times that of water tofu. Using tofu to replace meat and vegetables will greatly increase the calcium content. 6, nuts - hazelnut Hazelnut has the highest calcium content in various nuts, and the calcium content per 100 grams of fried hazelnuts is as high as 815 mg, which can meet the daily calcium requirement of adults. However, nut energy is generally high, a small amount per day. 7, beans - kidney beans Per 100 grams of skin kidney beans containing 349 mg of calcium, is nearly twice that of soybeans, with spiced kidney beans, plum beans as snacks or appetizers, after all, is a good way to calcium. 8, drinks - milk Milk is a good source of calcium, drink 250 grams (a bag) of milk, about 275 mg of calcium can be obtained, and easy to drink and absorb well. Extended reading Calcium can not be the same as eating 5 kinds of food 1. Caffeine Statistics show that drinking more than 4 cups of coffee a day will affect the absorption of calcium; daily consumption of more than 300 mg of caffeine will accelerate the loss of calcium. In addition to coffee, chocolate, strong tea and some refreshing drinks are also important sources of caffeine. 2, phosphoric acid Phosphoric acid is a medium-strong acid that has a strong binding capacity with metal ions, and the solubility of phosphate is very low. In the digestive tract, phosphoric acid reduces the absorption and utilization of various trace elements such as calcium, iron, zinc, and copper. Cola, sweet drinks, processed meat products contain more phosphate. 3, alcohol Excessive alcohol consumption can impair liver function, which can affect the metabolism of vitamin D, which is not conducive to the absorption of calcium. It is recommended that adult males drink no more than 25 grams of alcohol a day, which is equivalent to 750 milliliters of beer, or 250 milliliters of wine, or 50 grams of highly white spirits. Adult women drink less than 15 grams of alcohol a day, equivalent to 450 milliliters of beer, or 150 milliliters of wine, or 30 grams of high white spirits. 4, sodium British scientists in the study of salt (sodium chloride) found that the more salt intake, the more calcium in the urine, the poorer the absorption of calcium. In addition to eating less salt, it is recommended that you read the food labels carefully when choosing foods and choose products with low sodium content. 5, oxalic acid Oxalic acid is a ubiquitous substance in vegetables. If foods with high oxalic acid content are frequently eaten together with tofu, dried bean curd, milk and other high calcium foods, calcium oxalate that is not easily absorbed will be generated, which may cause urinary tract stones. Studies have shown that spinach, leeks and other oxalic acid vegetables can remove 40% to 70% of oxalic acid by boiling water.
Carbomer is an acrylic resin obtained by cross-linking pentaerythritol with acrylic acid. It is a very important rheological regulator. After neutralization, carbomer is an excellent gel matrix, which has important applications such as thickening suspension. According to the dry product calculation, including carboxylic acid group (-cooh) should be 56.0 % ~ 68.0%.
Common carbopol series include: Carbopol 940, 941, 934, 1342, 980, ETD 2020, AQUA sf-1, Ultrez 21, Ultrez 20, etc.
