Physical Indicators for Foreign Metal Detection in Frozen Vegetables

The detection of metal contaminants is a critical control point in frozen vegetable production. Therefore, the physical specifications primarily involve inspecting finished products for ferrous and non-ferrous metal impurities. Additionally, inspections for hair, insects, sand/stone, and plastic in semi-finished products are included.

Hair: Prior to implementation, the average detection rate was 8.66 strands per 100 people per day. After implementation, the average detection rate was 6.68 strands, showing a statistically significant difference.

Insects: Prior to implementation, an average of 26.60 insects were detected per 10 tons of product. After implementation, the average detection rate was 23.34, showing a statistically significant difference.

Sand/Stone: Prior to implementation, an average of 1.75 instances of sand/stone were detected per 10 tons of product. After implementation, the average detection rate was 0.81, showing a statistically significant difference.

Plastic: Prior to implementation, an average of 1.52 plastic fragments were detected per 10 tons of product. After implementation, the average detection rate was 0.94, showing a statistically significant difference.

Finished Product Indicators:

Glass: Prior to implementation, an average of 0.04 glass fragments were detected per 10 tons of product. After implementation, the average detection rate was 0.03, showing a statistically significant difference.

Metal: Prior to implementation, an average of 0.23 metal fragments were detected per 10 tons of product. After implementation, the average detection rate was 0.21, showing a statistically significant difference.

The above details the physical control indicators for foreign metal detection in frozen vegetables. We place utmost importance on the quality of our frozen vegetables, and you can consume them with confidence.
