Beidaihe compressed biscuits are not for military use. According to the relevant inquiry information, Beidaihe compressed biscuits seem to be military green packaging, but in fact they are produced by Qinhuangdao Fushou Food Co., Ltd., and the compressed biscuits are mainly military and civilian. The difference between them is that palm oil is used for military compressed biscuits and vegetable oil is used for civilian compressed biscuits. Palm oil contains a lot of glycerol, which can prevent food from being hydrogenated and oxidized without changing its taste for a long time.
