Preservation of foods or foodstuffs, in general, e.g. pasteurising, sterilising, specially adapted for foods or foodstuffs (preservation of flour or bread A 21 D; processes specially adapted for particular foods or foodstuffs, see the relevant groups for the foods or foodstuffs in A 23; preserving foods or foodstuffs in association with packaging B 65 B 55/00; preservation of alcoholic beverages C 12 H)

by heating using irradiation or electric treatment (drying or kilning A 23 L 3/40) [5]

using micro-waves or dielectric heating [5]

by treatment with pressure variation, shock, acceleration or shear stress [5]

by heating materials in packages which are progressively transported, continuously or stepwise, through the apparatus (A 23 L 3/005 takes precedence) [5]

with packages on endless chain or band conveyers

with packages transported along a helical path

with packages on a revolving platform

by heating materials in packages which are not progressively transported through the apparatus (A 23 L 3/005 takes precedence) [5]

with packages in intercommunicating chambers through which the heating medium is circulated

by treatment with chemicals

in the form of gases, e.g. fumigation; Compositions or apparatus therefor [5]

in a controlled atmosphere, e.g. partial vacuum, comprising only CO₂, N₂, O₂) or H₂O [5]

in which an absorbent is placed or used (packages for foodstuffs with provision for absorbing fluids B 65 D 81/26) [5]

Oxygen absorbent [5]

in a controlled atmosphere comprising other gases in addition to CO₂, N₂, O₂ or H₂O [5]

in the form of liquids or solids [5]

Organic compounds; Micro-organisms; Enzymes [5]

Note

In groups A 23 L 3/3472 to A 23 L 3/3562, in the absence of an indication to the contrary, classification is made in the last appropriate place. [5]
