La teneur en prot\u00e9ines<\/h2><\/span>
<\/div><\/div><\/div>

Les prot\u00e9ines, sources d\u2019acides amin\u00e9s<\/strong>\u00a0et de\u00a0nutriments<\/strong>\u00a0ont \u00e9galement un int\u00e9r\u00eat de par leurs propri\u00e9t\u00e9s technologiques. Il existe deux types de prot\u00e9ines, les\u00a0solubles<\/strong>\u00a0repr\u00e9sentent 15 % et les\u00a0insolubles<\/strong>\u00a085%.<\/p>\n

Ces derni\u00e8res (les insolubles) s\u2019associent entre-elles en formant un r\u00e9seau glut\u00e9nique qui d\u00e9termine la qualit\u00e9 de la prot\u00e9ine. Il est donc pr\u00e9f\u00e9rable d\u2019avoir une quantit\u00e9 moindre de prot\u00e9ines de bonne qualit\u00e9, qu\u2019une grande quantit\u00e9 de prot\u00e9ines de moyenne qualit\u00e9.
\nC\u2019est pourquoi il est utile d\u2019associer un r\u00e9sultat de prot\u00e9ines \u00e0 un\u00a0r\u00e9sultat de gluten ou de z\u00e9l\u00e9ny<\/strong>\u00a0afin de les qualifier.<\/p>\n

Trois m\u00e9thodes sont utilis\u00e9es par le laboratoire OLCEA pour cette d\u00e9termination. La m\u00e9thode DUMAS, <\/strong>la m\u00e9thode KJELDAHL <\/strong>et la m\u00e9thode par infrarouge<\/strong>.<\/p>\n<\/div>
