Obtention of chickpea extract fermented (Cicer arietinum L.) for use as a milky exteusor. Chickpea (Cicer arietinum L) is cultivated in the North pan of México and it is considered a good source of vegetal protein of low cost (20% average), nevertheless, the 80% used for the exportation and only the 20% less was used for animal feeding. The main objective in this study is to obtain a fermented chickpea extract for using in dairy extensor. Chickpea water absortion kinetics were carried out in e temperature conditions: while the conditions were established, chickpea was grounded and fermented in differents amounts with its natural flora, L. casei, L. plantarum and a mixture culture of both microorganism in logaritmic phase. The results showed that the presence of microorganism of chickpea natural flora interferes during the fermentation, so before the inoculation it was necesary treat the chickpea extract (CE) termically in a dilution.l:4 during 20 min at 7.7 kg/cm2 of pressure. The use of a mixture culture of 5% of L. casei and 5% L. plantarum inoculated in MRS broth was used to decrease fermentation time. Its adition in logarithmic phase to the sterile chickpea extract increased the lactic acid production and decreased the pH value in 6 h which was less time that one obtained with each of lactobacillus. The fermented extract obtained finally, presented similar sensory characteristics to the ones of dairy products. Therefore, chickpea is a good alternative as a extensor for this kind of products.
