Abstract

The invention discloses an instant seaweed antibacterial packaging material with a shelf life indicator label, and belongs to the technical field of food packaging. According to the instant seaweed antibacterial packaging material, a polyethylene film is soaked in a lysozyme solution with the concentration being 0.5 g / L to obtain the packaging material which is capable of inhibiting the growth ofmicroorganisms, preventing the microorganisms from multiplying on the surface of the packaging material, retaining the original flavor and nutrients of the food, and ensuring the quality and safety ofthe food; and meanwhile, a pH indicator label is produced and attached to the packaging material so that the shopper can distinguish the edible period of the seaweed conveniently without eating by mistake. The packaging material not only helps the consumer to conveniently select the food, but also can ensure the safety of the food and prolong the shelf life thereof.

Description

technical field [0001] The invention belongs to the field of food packaging, and in particular relates to an instant seaweed antibacterial packaging material with an indication label for identifying shelf life. Background technique [0002] Instant seaweed concentrates various B vitamins in seaweed, especially riboflavin and niacin, as well as a lot of vitamin A and vitamin E, and a small amount of vitamin C. Seaweed contains about 15% minerals, including potassium, calcium, magnesium, phosphorus, iron, zinc, copper, manganese, etc. necessary for maintaining normal physiological functions, and the content of selenium and iodine is particularly rich, which can meet the nutritional needs of consumers. need. The benefits of instant seaweed are not only in terms of nutrition, but its health effects are even more admirable. British researchers discovered in the 1990s that seaweed can kill cancer cells and enhance immunity. The phycobiliprotein contained in seaweed has the appl...
