How to choose to buy the safe tea-seed oil

How to choose to buy the safe tea-seed oil
Go wrong report of the food again and again recently, have to let people sigh for our food security issue, is there safe food now? Yes, in the face of these though we are very helpless, but the one that went wrong after all is still minority, we can try hard to avoid this question too while choosing the goods.
Though the great tea-seed oil of gold has gone wrong, the trade company has appeared recognition, but to the tea-seed oil, everybody can still buy.
The nutrition of the tea-seed oil is still worth buying
The nutritive value of the tea-seed oil can be said to be very high, its fatty acid forms and is similar to olive oil, among them unsaturated fatty acid is up to more than 90%, simple unrighted acid takes the amount of 73%, contain a certain amount of Vitamin E. Because the proportion of fatty acid of the tea-seed oil is rational, to preventing cardiovascular vessel disease beneficially, paid attention to by educational circles of nutrition, one is a kind of oil with higher nutritive value. The tea-seed oil flavor is good outside the forest, able to bear storing, high temperature resistant, is suitable to be frying the vegetable oil and fries and press oil to use, the family hoping to use olive oil can use tea-seed oil as the substitute too.
The method to rest assured most: Choose for the pigeonholing and extracting oil of healthy nutrition
But we give up, soak, produce oil on choice, choose, press, extract oil, in this way will prevent the intersection of gold and great tea-seed oil from include benzene and the intersection of Zhyuan and carcinogen exceed standard appearance of question this.
It is two kinds of methods that the oil of camellia draw to press the law and infusion law. It is to press the way to press the law with physics, thus coming the name of the justice of thinking is passed and suppressed, the extrusion that does one's utmost and oil produced out such as we take one and loose seeds, the sunflower seed is pressed on a piece of thin paper with strength, will find soon the paper has been soaked by the oil, the oil that and we bought is the machine is pressed out, this kind of oil is because of simple technological process, produce oil rate to be low, nutrition maximum to keep, come down at the same time, the oil fine oil thus, the price is slightly a bit more expensive too. ,; The infusion rule is to use the physical chemistry principle, pump a method to propose the oil of camellia from the tea-oil camellia seed by eating one grade of solvents.
Because of pressing the oil yield of the law very low, so the general trade companies will all adopt the above-mentioned two kinds of methods with complementary method, press and get the seed process of the tea-oil camellia " Press the original tea-seed oil " And then, " deep fried pancake " Inner remaining tea-seed oil, and then fully smoke and put forward with infusion law, win " original tea-seed oil of infusion " .
Should present on this link when exceeding standard benzene and Zhyuan. Lead in order to improve to produce oil, peasant households may toast, steam and fry to tea seed repeatedly, if temperature control fine, apt to result in, scorch phenomenon, produce benzene, combine Zhyuan, remain at the intersection of tea and outer cover of seed; And benzene and Zhyuan all remain in tea cake after pressing, while extracting the residual oil in tea cake, residual benzene and Zhyuan are extracted out in a large amount, through the high temperature and the chemical reaction take place in the solvent oil again, lead to the fact maos of the intersection of tea-seed oil and benzene under infusion finally and Zhyuan's content raise constantly.
So no matter tea-seed oil, or which kind of oil, it is the best choice to press and extract oil.
