Strains belonging to the genus Cladosporium can cause black spots on the surface of sheep cheese, making it impossible to sell. Two water solutions of chestnut tannin extract (i) 200 g L-1 (CHE200) and (ii) 400 g L-1 (CHE400), and the chestnut tannin extract powder (CHEP) were tested in a cheese making trial in which 60 cheese units were allotted to 5 experimental groups (each of 12 cheeses: C1, control 1 without any treatment; C2, control 2 treated with a silver ion solution; and cheeses LCHE200, LCHE400, and LCHEP, treated with CHE200, CHE400, and CHEP, respectively). The cheeses were ripened in a room polluted with Cladosporium cladosporioides with the aim to create conditions for the proliferation of this fungus on the cheeses.

Abstract
Strains belonging to the genus Cladosporium can cause black spots on the surface of sheep cheese, making it impossible to sell. Two water solutions of chestnut tannin extract (i) 200 g L-1 (CHE200) and (ii) 400 g L-1 (CHE400), and the chestnut tannin extract powder (CHEP) were tested in a cheese making trial in which 60 cheese units were allotted to 5 experimental groups (each of 12 cheeses: C1, control 1 without any treatment; C2, control 2 treated with a silver ion solution; and cheeses LCHE200, LCHE400, and LCHEP, treated with CHE200, CHE400, and CHEP, respectively). The cheeses were ripened in a room polluted with Cladosporium cladosporioides with the aim to create conditions for the proliferation of this fungus on the cheeses. The results indicated that chestnut tannin extract at a concentration of 200 g L-1 is capable of completely inhibiting C. cladosporioides proliferation, avoiding spoilage of the sheep cheese.File | Dimensione | Formato | |
