Polyethylene terephthalate (PET) Carbonated beverage bottles are mainly used for the packaging of carbonated beverages, and this resin will oxidize and degrade acetaldehyde at high temperatures. The residual acetaldehyde in the bottle is separated from the bottle by diffusion Body, but also to the water and air diffusion. Acetaldehyde is a volatile liquid with a fruit flavor, although it is often used as a food additive, but its migration to water also causes bottled beverages.
Tengzhou City, the vast chromatographic equipment Technology Co., Ltd., advancing with the times to scientific development as a guide, under the leadership of Wang Xiaoying manager, relyingShielding= 2) when the content of acetaldehyde in the sample was 29.7020μg / g. The
