Tuber aestivum/uncinatum has been widely used as food, food additives, and traditional medicine. Truffles are extremely perishable with a short postharvest life quality requiring a special handling for marketing in order to delay its deterioration. This study aimed to assess the effects of different sanitizing methods on superficial Tuber aestivium quality ascocarp. The results showed that the best treatment was obtained by immersing the Truffle ascocarps in boiling water for 1 or 2 min where counts of total mesophilic microoraganisms (TMM) were respectively 81 and 7 CFU per g of dry Truffle ascocarps biomass, respectively. However, the highest TMM was obtained after rinsing Truffle ascocarps in 2% NaOH where recovery was 10 8 CFU per g of dry Truffle ascocarps biomass. Treatments applied to disinfect Truffle ascocarps were classified by increasing degree of efficiency as follows to reduce the microbial load expressed in CFU/g: Dipping in boiling water (2 min) 7 ± 3.41; dipping in boiling water (1 min) 81 ± 25.8, rinsing with alcohol 2.10 2 ± 13; rinsing with tap water 6.10 3 ± 36; rinsing with H2O2 6.10 4 ± 2; brushing 2.10 5 ± 28 and rinsing with NaOH 10 8 ± 15.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
