\u4e00\uff0ePropri\u00e9t\u00e9 du produit\uff1a<\/h4>\n

Acidit\u00e9 douce : L'acide lactique a un go\u00fbt l\u00e9g\u00e8rement acide et convient pour l'assaisonnement.<\/p>\n

Effet antimicrobien : il peut inhiber efficacement la croissance des micro-organismes pathog\u00e8nes et prolonger la dur\u00e9e de conservation des aliments.<\/p>\n

Solubilit\u00e9 dans l'eau : L'acide lactique est facilement soluble dans l'eau et peut \u00eatre m\u00e9lang\u00e9 avec de l'eau, de l'\u00e9thanol, etc. librement, ce qui le rend pratique \u00e0 utiliser.<\/p>\n

\u4e09\uff0eApplication du champ d'application et de l'utilisation\uff1a<\/h4>\n

Industrie alimentaire : L'acide lactique est largement utilis\u00e9 dans les aliments tels que la viande, les boissons, la vinification, les bonbons et le pain, car il permet de r\u00e9guler les niveaux de pH, d'am\u00e9liorer la saveur et de prolonger la dur\u00e9e de conservation.<\/p>\n

Produits laitiers : En tant qu'ingr\u00e9dient naturel, l'acide lactique est largement utilis\u00e9 dans les yaourts, les fromages et les cr\u00e8mes glac\u00e9es, dont il renforce la saveur et les propri\u00e9t\u00e9s antimicrobiennes.<\/p>\n

Produits \u00e0 base de viande : Les d\u00e9riv\u00e9s tels que le lactate de sodium et le lactate de potassium sont utilis\u00e9s dans la transformation de la viande, car ils peuvent absorber l'humidit\u00e9 et inhiber la croissance des bact\u00e9ries de d\u00e9t\u00e9rioration. Boissons : Dans les jus de fruits et les boissons non alcoolis\u00e9es, l'acide lactique sert d'acidifiant, rehaussant le go\u00fbt et maintenant la stabilit\u00e9 du produit.<\/p>\n

 <\/p>\n

\u56db\uff0ePackage et stockage\uff1a<\/h4>\n

L'acide lactique est g\u00e9n\u00e9ralement conditionn\u00e9 dans des f\u00fbts en poly\u00e9thyl\u00e8ne haute densit\u00e9 (PEHD) de 25 kg\/baril, des conteneurs en acier inoxydable ou des conteneurs IBC en plastique de qualit\u00e9 alimentaire afin d'\u00e9viter la corrosion et la contamination. L'emballage doit \u00eatre herm\u00e9tiquement ferm\u00e9 pour \u00e9viter l'absorption d'humidit\u00e9 et l'oxydation.<\/p>\n

 <\/p>\n

Pour le stockage, l'acide lactique doit \u00eatre conserv\u00e9 dans un endroit frais, sec et bien ventil\u00e9, \u00e0 l'abri de la lumi\u00e8re directe du soleil, des sources de chaleur et des mati\u00e8res incompatibles (par exemple, les oxydants puissants).<\/p>","protected":false},"excerpt":{"rendered":"
