Problems solved by technology

The existing preservatives commonly used in food mainly include the following categories: benzoic acid, which is a food preservative allowed to be used in countries all over the world. Most of the domestic preservative market; Butylated hydroxyanisole (BHA), is one of the antioxidants widely used in the world, and has a strong anti-microbial effect, mainly used in edible oils, the maximum dosage is 0.2g / kg, The disadvantage is that the cost is high; butylated hydroxytoluene (BHT) is currently one of the antioxidants with the largest production in my country, and the price is low, which is 1 / 5 to 1 / 8 of BHA, but the antioxidant property is not as strong as BHA. The range is the same as BHA, the disadvantage is higher toxicity
But no matter the above-mentioned preservatives have toxic ingredients and chemical ingredients, they cannot be truly natural and harmless.
