Cassava ( Manihot esculenta Crantz) starch-based vegetable beverage (cassava milk) was formulated to get a composition close to that of cow’s milk with 3% cassava starch, 4% soybean proteins, 3% soybean oil and 0.3% calcium citrate. Heat treatment of the dry starch at 110 °C for 6 h was done prior to the addition of other components to stabilise milk and to avoid gelatinisation. The most stable form of cassava milk that did not separate into two phases for 10 days was obtained by homogenisation at high pressure 12,000 psi/5 min. Milk with starch particle size of 10 μm was found to have sensory qualities close to that of cow’s milk with white colour and viscosity of 7.8 cP. Cassava milk homogenised at 12,000 psi/5 min with cow’s milk (50%) and aromatised with 1% chocolate flavour was given the highest score by 20 sensory panellists. The final product was a white milky solution with good taste, good digestibility, homogeneous, physically and microbiologically stable, and had a nutritional composition simila...

The performance of a tapered reactor for the continuous cultivation of bakers' yeast (SCP) from cane molasses has been compared with that of a conventional cylindrical reactor. It is found that the tapered reactor has less non-idealities (bypass and deadspace).

Inspection of food for the presence of Salmonella is a major concern in food industry. Many rapid, reliable and sensitive novel methods have been developed to detect Salmonella from food samples. However a method to detect live bacterial cells separately from dead cells yet to be developed. Although fluorescent in situ hybridization (FISH) has been identified as promising method in this regards, the viable count could be overestimated by FISH technique due to dead cells with some amount of non degraded rRNA. Some times it could be underestimated because of inactive but viable cells which not produce detectable amount of rRNA. The possibility of using antibiotic treatment step in FISH technique to overcome this problem was studied. Chicken samples inoculated by differently prepared mixtures of live and heat killed Salmonella enterica cultures were used to isolate bacterial cells with and without antibiotic treatment (Nalidixic acid 10μg/ml and Ciprofloxacin 1μg/ml for 2h at 370C). FISH was performed with Salmonella specific 23S rRNA probe Sal3, 5’-AATCACTTCACCTACGTG-3’ labeled with fluorescein isothiocyanate (FITC) at 5’ end. Cells observed with high intensity under fluorescent microscope were identified as live cells. Results of statistical analysis for antibiotic treated and untreated samples indicated that the introduction of antibiotic treatment step in FISH technique permitted a successful application to over come the problem associated with viable Salmonella enterica detection and quantification.
