Description
Summary:ABSTRACT Tuber floridanum is the first truffle species reported in Brazil and little is known about its nutritional properties and ecology. Therefore, this study aimed to (1) determine T. floridanum aroma and nutritional properties and (2) analyze cultivation and fruiting conditions, including potential crop pests and market value. Fruiting bodies of T. floridanum showed a slightly ellipsoid shape and smooth to shallow groovy surface. The mass of ascocarps ranged from 0.13 g to 15.95 g, and the truffle was composed of 71 % carbohydrates, 19 % protein, 5 % ash, and 5 % of fat. Octan-3-one, 1-methoxy-3-methyl-butane, and 1-methoxy-2-methyl-butane determined T. floridanum characteristic aroma. Soil properties were also specific for this truffle, differing from optimal soils where commercial truffles are produced. In addition, the occurrence of earwigs (Anisolabididae, Anisolabidinae) feeding on truffles (26 % of all ascocarps) in pecan orchards may reduce truffle quality and cause financial losses. T. floridanum aroma has a unique composition, completely different from any commercial and non-commercial truffle species analyzed so far. Soil conditions in pecan orchards were also specific for truffle fruiting. Further studies should elucidate other ecological conditions for the co-production of T. floridanum with pecan .
