Antiseptic may be ascorbic acid or acetylsalicylic acid or mixture of ascorbic acid and acetylsalicylic acid used at the rate of 0.01-20 mg of food product weight per 1 cu.cm of package volume. Absorbent may be molecular sieve or mixture of molecular sieves and activated carbon or mixture of calcium chloride and molecular sieves used at the rate of 1-30 mg of food product weight per 1 cu.cm of package volume.
