Multicomponent analysis of meat products by infrared spectrophotometry: collaborative study

Area of Science:

• Food Science
• Analytical Chemistry
• Spectroscopy

Background:

• Accurate nutritional analysis of meat products is crucial for quality control and consumer safety.
• Traditional methods for determining protein, fat, and water content can be time-consuming and labor-intensive.

Purpose of the Study:

• To evaluate a novel infrared transmission method for the rapid, simultaneous analysis of protein, fat, and water in diverse meat products.
• To validate the performance of this new method through a collaborative study involving multiple laboratories.

Main Methods:

• A multicomponent analysis was performed on 31 meat product samples (including raw meats, cooked sausages, liver sausages, and fermented sausages).
• Samples were analyzed using the infrared transmission method and compared against established reference methods for protein, fat, and water content.
• Four independent laboratories participated in a collaborative study to ensure reproducibility and robustness of the results.

Main Results:

• The infrared transmission method demonstrated no significant difference compared to established reference methods for determining protein content (p > 0.05).
• Similarly, no significant differences were observed for fat content determination (p > 0.05).
• The method also showed high accuracy for water content analysis, with no significant deviation from reference values (p > 0.05).

Conclusions:

• The rapid multicomponent analysis method based on infrared transmission is a reliable and accurate technique for determining protein, fat, and water in various meat products.
• This method offers a viable alternative to traditional techniques, potentially improving efficiency in meat product analysis.
• The collaborative study validates the robustness and applicability of the infrared method across different laboratory settings.
