Quality requirements of oxygen absorber for food
1 Scope
This document specifies the product classification, technical requirements, inspection rules, labeling, marking, packaging, transportation and storage requirements of oxygen absorber for food, and provides the inspection methods of mass of oxygen absorber for food.
This document is applicable to the production, inspection and marketing of oxygen absorber for food produced by food raw and auxiliary materials.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition (including any amendments) applies.
GB/T 191 Packaging—Pictorial marking for handling of goods
QB/T 1130 Plastics angle tear performance test method
QB/T 2358 Test methods for heat-sealing strength of plastic film packaging bags
3 Terms and definitions
For the purpose of this document, the following terms and definitions apply.
3.1
oxygen absorber
product that can react with oxygen within the specified time to reduce the oxygen concentration in food packaging to less than 0.1% (volume fraction) and keep it for a certain time
Note: It can be classified into oil-proof and water-proof type and non-oil-proof and water-proof type according to its oil-proof and water-proof performance.
3.2
total oxygen absorbed capacity
maximum oxygen absorbed capacity
maximum volume of oxygen that can be absorbed by the unit packaging product within a specified time under normal temperature and pressure
3.3
nominal oxygen absorbed capacity
minimum oxygen absorbed capacity required for unit product to reduce the oxygen concentration in the confined space to less than 0.1% (volume fraction) and keep it for a certain time
3.4
oxygen absorbed speed
time required for the unit packaging product to reduce the oxygen concentration in the corresponding confined space to less than 0.1% (volume fraction) under normal temperature and pressure
3.5
leakage-proof performance
performance of preventing leakage of package contents
4 Technical requirements
4.1 Requirements for raw and auxiliary materials
The requirements of relevant standards shall apply.
4.2 Sensory requirements
It shall meet those specified in Table 1.
