Refrigerated and Frozen food Safety Testing

Refrigerated and frozen foods have become an important part of people's daily diet. Due to management and technology, there are still some deficiencies in the food cold chain (including procurement, processing, storage, transportation, etc.). Its sensory quality and nutritional value various aspects such as hygiene and safety will be affected to various degrees. Therefore, it is very important to monitor the food quality in circulation. The factors that cause food deterioration mainly include the effects of microorganisms, enzymes, respiration, oxidation, mechanical damage, and the external environment such as light, temperature fluctuation, and humidity. Although the decrease in temperature can delay and weaken the activity of microorganisms and enzymes, it cannot completely suppress their effects. Therefore, after long-term storage, the quality of food will always decline. Alfa Chemistry offers validate drefrigerated and frozen food analytical methods to satisfy your needs.

The food cold chain is divided as follows according to the different food storage temperature:

• Frozen food chain (0-15 °C)

• Chilled ice temperature cold chain (0 °C below the scope of the respective freezing point)

• Freeze food chain (-18 °C)

• ultra-low temperature cold chain (-45 °C or less)
