Quality attributes of Bearss Seedless lime (Citrus latifolia Tan) juice during storage.

The composition of three types of date juices, that differs by their couple of extraction and obtained from the rest of the sorting of cultivars Deglet Nour, were studied. The fruits were grown in Djerid region (Tozeur, Tunisia). Juices were characterised by yield, pH, soluble solids, organic acid, minerals content, individual carbohydrates, vitamin C, yeasts and moulds, coliforms and flora total aerobe contents. For the physicochemical parameters, only the J3 presents the best yields with content in citric acid of 2.13 g L-1, in phosphor of 0.083% (dry mater), in glucose 26.529 g L-1, in fructose 39.59 g L-1 and in sucrose 185.883 g L-1. For the bacteriological parameters, the results show that all prepared juices answer the microbiological requirements of hygiene well
