Title
(EN) SYSTEM AND METHOD FOR EARLY DETECTION FOR PREVENTION OF POSTHARVEST CHILLING INJURY
(FR) SYSTÈME ET PROCÉDÉ DE DÉTECTION PRÉCOCE POUR LA PRÉVENTION D'UN ACCIDENT DE RÉFRIGÉRATION POST-RÉCOLTE
Abstract
(EN)
Aspects of the present invention include detection of volatile compounds related to response of vegetable or fruit, (e.g., mango), as result of stress like suboptimal temperature. Such response may lead to activation of some metabolic pathways that can induce synthesis of volatile compounds which may serve according to embodiments of the present invention as signals which indicate onset of CI and/or deterioration of fruit quality. The release of such volatiles compounds may be detected long before CI symptoms become notable. According to some embodiments of the invention, output from sensors detecting presence of volatile compounds indicating that fruits are starting to suffer from chilling stress, are received by at least one control module which operates conditioning system so as to alter storage conditions for avoiding CI and/or quality deterioration of fruits or vegetables.
(FR)
Des aspects de la présente invention comprennent la détection de composés volatils liés à la réponse d'un légume ou d'un fruit (par exemple, une mangue) suite à une contrainte comme une température sous-optimale. Une telle réponse peut conduire à l'activation de certaines voies métaboliques qui peuvent induire la synthèse de composés volatils qui, selon des modes de réalisation de la présente invention, peuvent servir de signaux qui indiquent l'apparition d'un accident de réfrigération et/ou la détérioration de la qualité des fruits. La libération de ces composés volatils peut être détectée longtemps avant que les symptômes d'accident de réfrigération puissent être constatés. Selon certains modes de réalisation de l'invention, la sortie de capteurs détectant la présence de composés volatils indiquant que les fruits commencent à souffrir d'une contrainte de réfrigération est reçue par au moins un module de commande qui fait fonctionner le système de conditionnement de façon à modifier des conditions de stockage pour éviter un accident de réfrigération et/ou une détérioration de la qualité de fruits ou de légumes.
