ISO 31871 Protein Digestibility Analysis in Plant-Based Foods
The ISO 31871 standard outlines a method for determining protein digestibility in plant-based foods, which is crucial for ensuring the nutritional value and safety of these products. This analysis helps manufacturers understand how efficiently proteins are broken down during digestion, impacting not only the product’s quality but also its compliance with international standards.
In recent years, there has been a significant rise in demand for plant-based foods due to health-conscious consumers and environmental concerns. However, not all plant-based proteins are easily digestible or readily absorbed by the human body. Accurate protein digestibility analysis ensures that these products meet consumer expectations and regulatory requirements.
Protein digestibility is measured using a series of tests designed to mimic the conditions found in the human digestive system. The process involves hydrolysis and subsequent quantification of amino acids, which are then compared against reference values established by international standards such as ISO 31871. This analysis provides insights into both the quality and quantity of digestible protein present in plant-based foods.
The importance of this test cannot be overstated, especially for those involved in food safety and quality management. By ensuring that proteins are sufficiently digestible, manufacturers can enhance consumer trust and satisfaction while also avoiding potential legal issues related to non-compliance with dietary regulations.
For research and development (R&D) engineers working on new plant-based products, this analysis offers critical data points for optimizing formulations and improving overall product performance. Similarly, compliance officers rely on such testing results to demonstrate adherence to relevant food safety guidelines and standards.
Scope and Methodology
The ISO 31871 standard specifies a procedure for determining the protein digestibility of plant-based foods using in vitro digestion. The method involves several key steps:
- Sample preparation: Properly drying, grinding, and homogenizing the sample to ensure uniformity.
- Preparation of digestive fluids: Mimicking human gastric juice with appropriate pH levels and enzymes.
- Digestion simulation: Incubating the sample with digestive fluids under controlled conditions that simulate physiological processes.
- Protein recovery: Using methods like centrifugation to separate undigested proteins from digested ones.
- Amino acid analysis: Quantifying free amino acids using high-performance liquid chromatography (HPLC).
The results of these analyses provide a comprehensive picture of the protein digestibility of various plant-based foods, helping stakeholders make informed decisions about formulation and quality assurance.
Industry Applications
