Modifier Tutorial : Pasteurisation de fruits et légumes/en

This tutorial has been created in collaboration with Claire Yobé, an expert in pasteurisation with many years of experience in the field. The aim is to easily preserve surplus fruit and vegetables for long-term storage, whether from your vegetable patch (in Summer for example), or because you have bought more than you need. <div class="mw-translate-fuzzy"> '''Key facts on food wastage:''' * 1/3 of food produced around the world goes off or is wasted * In France, 50% of waste happens at home * A person in France wastes 20kg of food per year * 19 % of fruit and 31% of vegetables are wasted, making these the produce we waste the most '''What is pasteurisation?''' </div> *1/3 des aliments produits dans le monde est perdu ou gaspillé *En France, 50% du gaspillage se fait à la maison *Un français gaspille 20kg d'aliments par an *Les légumes et les fruits sont des plus gaspillés avec respectivement 31% et 19% des pertes '''Qu’est ce que la pasteurisation ?''' Pasteurisation is a process used to preserve food. It consists in heating food to 80°C before being bottled or preserved in jars, followed by cooling. '''How is it possible to preserve food by means of pasteurisation?''' By heating fruit and vegetables to 80°C, a large proportion of pathogenic micro-orgnanisms are destroyed. Placing food in containers at this temperature drives oxygen out and prevents the remaining pathogens from multiplying. '''What kind of foods can be preserved through pasteurisation?''' All kinds of fruit and vegetables can be easily preserved by means of pasteurisation. However, this method cannot be applied to meat or fish since 100% of the pathogens present need be destroyed, which can be achieved through sterilisation. '''What nutritional value do pasteurised foods have?''' Cooking clearly diminishes nutritional value as it reduces the vitamin and protein content in food. Pasteurisation is one of the heat treatment processes which least reduces nutritional value as the food is not heated to very high temperatures, contrary to sterilisation which can reach temperatures of up to 120°C. '''How should we consume pasteurised foods?''' You can consume as much pasteurised fruit and as many pasteurised vegetables as you wish. Once the container has been opened, it should be stored in the fridge and the contents eaten within 7 days. '''Are there any risks involved with pasteurisation?''' As with all heat treatment methods for food preservation, it is vital that the jar or tin be airtight. If air penetrates the container, pathogenic micro-organisms may develop. Et même si de l'air ne s'infiltre pas, cette technique ne les détruira pas : ils peuvent potentiellement se développer plus tard, même après des années si le PH de la préparation est supérieur à 4.5 (viandes et légumes). Pour éliminer tout risque, il faut respecter un rapport durée/t° de la chauffe à cœur du bocal allant de 5mn à 10h suivant la pression. Vous trouverez ces rapports sur ce [[Stérilisation respectant un barême professionnel|TUTO]] <div class="mw-translate-fuzzy"> This tutorial focuses on fruit and vegetables only where risk is very low. However, if in doubt and any suspicious smells or colours arise, do not hesitate to throw the preserve away. </div>
