tThe aim of this study was to determine (i) the chemical, physic-chemical and technological propertiesand (ii) the antioxidant and the antibacterial properties of tamarind (Tamarindus indica L.) powder extract(TPE) obtained from the fruit pulp, in view to its application in the food industry.Protein, fat, ash and total dietary fibre contents of TPE were 2.06, 3.03, 8.95 and 19.30 g/100 g d.m.,respectively. Furthermore, glucose and tartaric acid were presented in the largest amounts (155.65 and40.97 mg/g, respectively). DMSO tamarind extract contained the most phenolic (4.24 mg GAE/g) andflavonoids (127.16 mg RE/g) compounds. Methanolic extract of tamarind showed good antioxidant activ-ity in DPPH assay (92.62% inhibition of radicals) and FRAP assay (2.46 mmol TE/g) assays. While, DMSOextract exhibited the best metal-ion chelating properties (73.68%). Besides, tamarind extract possessedantibacterial activity against Gram-positive and Gram-negative bacterial. Results from this work suggestthat TPE could be used as an ingredient of functional food as well as natural preservative in food industry.
