| Comparison dimensions | GB/T 21290—2007 | GB/T 21290—2018 |
|---|---|---|
| Product specifications | Not specified | Add specific specifications |
| Sensory requirements | Include basic requirements | Refine frozen products and post-thawing indicators |
| Physical and chemical indicators | Include some indicators | Add volatile basic nitrogen limits |
| Safety indicators | Specifically list multiple residues | Uniformly cite GB 2733 |
Interpretation of the core content of the standard
Product specifications and classifications
Frozen tilapia fillets are divided into 5 specifications by weight, as shown in Table A.1:

|---|---|
| 57~85 | 2~3 |
| 86~141 | 3~5 |
Sensory requirements
The sensory indicators of frozen tilapia fillets are an important reflection of product quality. The specific requirements are shown in Table 1:
| Item | Requirements |
|---|---|
| Frozen products (before thawing) | Evenly covered with ice or ice, without obvious loss of moisture or softening. |
| Color after thawing | The color of tilapia is the same, without loss of moisture or discoloration. |
Implementation suggestions and precautions
To ensure the effective implementation of the standard, it is recommended that enterprises pay attention to the following points during production and inspection:
- Strictly purchase raw materials and conduct primary processing in accordance with the standard requirements.
- Strengthen the temperature monitoring of the frozen product center to ensure that it meets the requirement of ≤-18℃.
- Periodically test safety indicators, especially the control of volatile basic nitrogen.
