This study is a contribution to the adaptation of a system of quality control of processed namely HACCP to master the microbiological hazards encountered in the manufacture of food products reconstituted milk and pasteurized milk acidified following an investigation that drive to establish a plan HACCP hazard Analysis with determination to master critical point (CCP, critical Control Point). Microbiological control of contaminating microorganisms namely coliform and thermo-tolerant coliform test performed in duplicate and concern reconstituted pasteurized milk, acidified 'The Lben, milk powder, which serves to close the preparation of the Lben , rinse water and drinking water.

We are interested in the chemical study of some traditional herbal preparations used to treat gastric diseases in Bechar region. The traditional medicinal preparations used are the aqueous extracts of 11 medicinal plants (aerial part, leaves, seed), and the results of medical tests of preparation have shown interesting activities on gastric symptoms.

Urginea noctiflora a spontaneous plant used as a traditional medicine in Ghardaïa (Septentrional Sahara Algerian).The bulbs were characterized. The amounts of total phenolics varied widely in the extracts and ranged from 0.48±0.28 to 9.81±1.84mg GAE/g dry material in hexane and ethanol extracts respectively. The amounts of flavonoids were ranged from 0.158±0.06mg to 1.03±0.167mg. Water-soluble polysaccharides are 5.33%. Total antioxidant capacity of the plant extracts ranged from 0.11±0.05 to 4.56±0.13mg vitamin C equivalent per gram of dry matter for the hexane extracts and ethanol respectively. All extracts were active against some or the entire tested microorganisms Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella thyphimurium, and Candida albicans.
