1. Does this product affect the nutritional value of the oil? A: No. ZOILSIL-GZ R92 only physically adsorbs impurities and pigments in the oil, does not react with the nutritional components (such as fatty acids, vitamins) in the oil, and will not affect the nutritional value of the oil. 2. Can this product be used in combination with other refining agents? A: Yes. It can be used in combination with other food-grade refining agents (such as activated carbon), which can improve the refining effect, reduce the dosage of other agents, and reduce production costs.
