The opportunistic pathogenic yeast in orange juice and its control strategy.

Yeasts are ubiquitous in orange juice some of them are harmless to the human body.However,recent studies show that the existence of some yeast not only can result in spoilage of orange juice,but also can cause disease to human.Yeast is one of the most common pathogens in orange juice.Considering the drink security of orange juice and its potential threat to human body health,more attention is paid to the pathogenic yeast by the people.Therefore,research on pathogenic yeasts has become a hot topic in life science fields.Now 14 species of pathogen yeast in orange juice were reported those are Candida parapsilosis,C.stellata,C.tropicalis,C.famata,C.colliculosa,C.zeylanoides,Clavispora lusitaniae,Cryptococcus neoformans,Debaryomyces hansenii,Hanseniaspora uvarum,Issatchenkia orientalis,Pichia anomala,Rhodotorula mucilaginosa and Trichosporon asahii.The present paper reviewed the species,identification methods and control strategy of pathogenic yeasts which would provide useful reference for the production,storage,sale and consumption of orange juice.
