摘要:
Ce procédé est du type consistant à imprégner les champignons par une substance coagulable, à les blanchir, puis à en remplir une capacité, et enfin à les soumettre à un traitement de conservation. Le problème posé consiste à accroítre le rendement en poids obtenu par le procédé. Suivant l'invention, on exécute l'imprégnation avec mise sous vide en une période de temps minimale, y inclus la mise sous vide (19), l'introduction (15) du liquide de traitement, un court maintien en contact et l'évacuation (16) du liquide. L'invention trouve une application avantageuse dans le traitement des champignons.

摘要:
Freshly picked washed mushrooms are subjected to a modified atmosphere and infused by application of positive or negative pressure with a solution containing a particulate heat stable gel forming material. Upon blanching in boiling water the weight loss experienced is reduced from a normal 25% to 33% loss to between a 2% loss and a 5% or more - weight gain.
摘要:
A process for improving the organoleptic properties of canned green vegetables wherein vegetables blanched with a highly alkaline solution are suspended in a brine having an alkalinity adjusted to between about 25 to about 75 milliequivalents of hydroxyl ion in a hermetically sealed container internally coated with an organic coating filled with an alkaline earth compound such as MgO, the vegetables being sterilized at 250°-300°F (121°-149°C) to an F. value of at least 6 whereby the original color and flavor of the vegetables are retained.
