3.Application scope and Usage
Isobutyl acetate has the aroma of apples and raspberries. It is often used as a fruit flavoring agent and is employed in the formulation of banana, raspberry, pineapple, strawberry, cream, raspberry and pear-flavored flavorings. It is also used as a blending agent for roses.
4.Package and Storage
Isobutyl acetate is packaged in 25kg HDPE plastic drums or galvanized iron drums. For food-grade products, it needs to be lined with PE film. It should be stored in a fireproof warehouse (< 25℃), away from fire sources and oxidants, and sealed tightly to prevent evaporation. The shelf life is 24 months.
