During the deterioration of food, VOCs will change significantly, and microorganisms will also produce stagnant gases such as acids, alcohols, ammonia and amines. The quality and freshness of the food can be known from the gas emitted from the food.
  • the current volatile gas detection of food is mainly gas chromatography and sensory evaluation, both of which are time consuming and laborious, and require professional personnel to complete.

Abstract

La présente invention concerne un procédé de fabrication d'une matière d'emballage capable de détecter la fraîcheur des aliments. Le procédé comprend les étapes suivantes : A) en fonction de différents aliments, sélection de différentes matières sensibles changeant de couleur sous l'effet de gaz capables de changer de couleur lorsqu'un gaz est émis lorsque des aliments se dégradent; B) sélection d'une enveloppe plastique de qualité alimentaire ou d'un papier sans acide comme matière d'emballage de base; C) dissolution des matières sensibles changeant de couleur sous l'effet de gaz sélectionnées respectivement dans des solvants organiques correspondants pour obtenir des solution à 0,1-0,5mol/L; D) adjonction de 5mol/L de stabilisant dans chacune des solutions; E) application des différentes solutions obtenues sur la matière d'emballage alimentaire de base par application jet d'encre pour former un réseau de matières sensibles changeant de couleur sous l'effet de gaz sélectionnées, ou application de l'une des solutions obtenues sur la matière d'emballage alimentaire de base pour former une ligne de points composés de la matière sensible changeant de couleur sous l'effet de gaz sélectionnée, puis séchage pour obtenir un type commun ou spécifique de matière d'emballage respectivement. La matière d'emballage obtenue a une fonction de réservation de la fraîcheur, et peut détecter la fraîcheur et la qualité d'aliments. La matière d'emballage sus-mentionnée peut être employée pour l'emballage de médicaments, de cosmétiques, et de produits chimiques anti-contrefaçon.
