Daily life in a variety of edible vegetable oil, edible oil currently is diverse, now Xiao Bian teach you several methods to identify the good and bad oil, I hope useful in your daily life. 1. The smell of oil scent. Stick a finger in a little oil, and put it in the palm, rub after smell it. Good quality oil in addition to the plant itself should have their own smell, in general, there is no other smell. If odor, indicating poor quality oil or deterioration. 2. Taste. Chopsticks stained with a little oil, put it on the tongue Bianqi flavor. Normal quality oil odor. Such as oil bitter, spicy, sour, hemp has gone then the sense of smell, burning smell of oil quality is not good. 3. Heat the identification. It occurs when water heating large edible vegetable oil press how much money a lot of foam 230, and the squeak of new 230 press, there is choking fumes spicy bitter oil rancidity when instructions. Good oil should be less foam quality and disappear quickly. Produced by centrifugal filtration plant oil filter design is developed from a practical point of oil extraction by 230 automatic press repeatedly proven through user which is money the most practical, the best, easiest to clean up easier oil mill Preferred oil filter. Now gradually eliminated frame type, vacuum, pneumatic and other old filter. Some of the problems encountered in practice for some customers following mechanical feedback: centrifugal oil filter filtration of cooking oil, a detailed analysis of crude oil must hydration: hydration principle: hydration is by heating the oil in water phospholipids, proteins, mucus and other impurities separation. I thought it would swell after absorbing phospholipids, so that the volume increases, combined with the phospholipids protein, mucus and other impurities, the relative density increases and sink precipitated. Hydration purpose:. ① dephosphorization, because phosphorus on the human body will produce osteoporosis and other diseases, so the first item is the index levels of phosphorus limited national oil standard, H2O NaCl (brine) and phosphorus compounds to form P produce heavy quality salt Na2P5O (sodium) and H2 ↑ (hydrogen) ② add salt so that fine particles absorb water becomes heavier; hydration methods: Presses hot crude oil added 1-1.5% thermal brine stir 230 press, concrete The amount of water should be based on the actual situation of crude oil, add more water is filtered oil also contains water, easy to rancidity, add less water the dephosphorization is not complete, the crude oil is not clean.
