Introduction
GB/T 33914—2017 Standard Overview
GB/T 33914—2017 "Feed Raw Material Spray-dried Porcine Plasma Protein Powder" is an important specification formulated for the production and quality control of spray-dried porcine plasma protein powder. This standard was proposed by the National Feed Industry Standardization Technical Committee and is applicable to the production and inspection of the feed industry and related fields.
Core Terms and Definitions
Spray-dried porcine plasma protein powder is a high-nutrition value protein product made from fresh blood of slaughtered pigs through separation, sterilization and spray drying. Its main characteristics include:
- Uniform color: white, light yellow or light pink
- Inherent odor: has the unique aroma of animal blood products
- Purity requirement: shall not contain other foreign components
Comparative analysis of technical indicators
| Item | Indicator requirements |
|---|---|
| Crude protein/% | ≥70.0 |
| Lysine/% | ≥5.5 |
| Immunoglobulin G (IgG)/% | ≥15.0 |
| Moisture/% | ≤8.0 |
Health and Safety Indicators
The standard sets strict requirements on the health and safety of products, including:
- Total bacteria count: ≤2×10^5 CFU/g
- Coliform bacteria: ≤1×10^3 MPN/100g
- Salmonella: not detectable
- Lead and total arsenic content: both not exceeding 0.5 mg/kg
Test methods and quality control
The standard specifies the test methods for various indicators in detail, including:
- Crude protein determination: GB/T 6432
- Lysine determination: GB/T 18246
- Immunoglobulin G determination: GB/T 21033
Implementation suggestions and precautions
Case Analysis: A feed company successfully improved the stability and nutritional value of its products by adopting spray drying technology. The company strictly followed the GB/T 33914-2017 standard during the production process and established a complete quality control system.
Suggestions for manufacturers:
- Perform regular type inspections to ensure product quality
- Optimize production processes to reduce impurities
- Strengthen raw material procurement management to avoid disease risks
