As the editor of the portal of the household oil press industry, it is necessary for me to answer this question.

1. Now Joyoung, AUCMA, SKG, Royalstar, South Korea's Hyundai, Konka and other brands are making household oil presses.

2. You are right, for thousands of years we have eaten crude oil, there is no so-called "refining", those merchants' "refining" and "degumming", "deacidification", "decolorization" and other "six decolorization processes" are to ensure that edible oil can be stored for a long time, after these processing, many of the nutrients in edible oil that are very beneficial to human health are greatly discounted. The oil pressed with a household oil press can be squeezed in small quantities, eaten and squeezed, squeezed less each time, and does not need to be stored for so long.

3. Yes, cold pressing and hot pressing have their own advantages. Cold-pressed oil retains nutrients to the greatest extent, and it is low in smoke shops, so it should not be used for high-temperature frying. Hot-pressed oil has a more fragrant taste, a higher oil yield, and a relatively high smoke point.

4. I don't know which household oil press you are talking about, so I will not answer. Answer the last question: The basic use of food-grade 304 stainless steel is used in the squeezing rod of household oil presses, which meets safety and health standards. If you see a household that is not food grade, it is a substandard product.

5. Now there are manufacturers who produce more efficient filter paper. In addition, the oil residue inside is only a very fine raw material for oil extraction that flows out of the cracks during pressing, and it is not a harmful substance and does not affect health. Generally, after squeezing the oil, it will be allowed to stand for a few hours, and the oil residue will precipitate and separate.

6. The acid value refers to the oxidative rancidity of edible oil, or that sentence, it is recommended to squeeze a small amount and more, and the squeezed oil is not easy to oxidize when stored at low temperature and protected from light. If you buy it back and plan to squeeze it once every six months or once a year, then what do you buy it for? Household oil presses are all intelligent fool-like operations, press a button to press their own press, and cleaning is also simple and convenient. Why can't you squeeze it often?

Industry development for a period of time, there will be industry standards, when this product first appeared, the technology is not mature is normal, now the household oil press has come out for a few years, the previous shortcomings have been improved, and the technical quality has been innovated.
