How to store butter?
Butter's requirements for packaging are mainly to protect its fragrance beads, organization, appearance, moisture, and color. Airtight packaging is very important to protect its fragrance from being lost and resist the pollution of external odors because butter can easily absorb foreign odors. Due to the emulsion characteristics of butter, the fat in it is particularly susceptible to oxidation and rancidity. The trace metal ions remaining on the machinery and equipment of the processing plant can also give the butter a "fishy" smell.
