Qualidade pós-colheita de frutos de tomateiro com uso de biofilme a base de Chrorella sp.

Abstract

The tomato is a vegetable widely grown in severas regions because of their adaptability and high demand for the fruit. However, post-harvest fosses are a major problem of this culture and can be minímized with the use of new low-post technologies. In this regard the aim of this study was to evaluate the effect of biofilm the bases of C/z/ore//a sp. at different concentrations in the post-harvest quality of tomate (So/anz/m /ycopersicum L.) stored at ambient conditions. This work was carried out in a completely randomized design with flve treatments (T0-witness; Tl- 1% of biomass CA/ore//a sp;. T2-2% of biomass C'#/ore//a sp; T3 3% of biomass C/z/ore//a sp; T4 4% of biomass CA/ore//a sp). Treating tomatoes with biofllm Cb/ore//a sp. in concentrations of 1% and 2% reduced weight loss of the fruit, but also delayed the development of bolor expressed by C +, a I' and b 'k values as well as the diameter, vitamin C and soluble solids.
