FIELD: food-processing industry, in particular, canning of vegetable products.
SUBSTANCE: method involves filling plastic bag with product adapted for thermal processing; sealing plastic bag and subjecting to thermal processing; cooling thermally processed product by means of cold water and simultaneously supplying into autoclave air under pressure for at least partial balancing of pressure inside hot plastic bag so as to avoid damage to said bags in the process of cooling; after temperature of bags has reduced up to 900C or below, providing pressure drop and continuing the process of cooling with cold water at ambient pressure. Bag manufactured from laminated material may be used for canning, said material having inner layer of polypropylene, intermediate layer of polyamide and outer layer of polyethylene terephthalate (dacron). Laminated material may be additionally provided with aluminum layer.
EFFECT: reduced cycle of thermal processing in autoclave, increased efficiency of autoclave and reliable pasteurization or sterilization procedures without causing damage to bag.
