Biphenyl absorption of treated orange

Absorption rate of biphenyl was determined in used pads, whole orange fruit, peel and juice stored under different conditions of ventilation, temperature and storage period. It was found that the rate of biphenyl a bsorption complied with the maximum permitted level of biphenyl in the United States and in most of the European Countries if packed in vented cartons as it is usually done commercially. However, with non-vented cartons, the absorption rate increased above the upper level of the a bsorbed biphenyl permitted by both Germany and France, when stored at 60F. Generally the non-vented cartons efficiently decreased the rate of orange decay compared with vented ones

Utilization of beet molasses in the production of lactic acid

The influence of various factors on the production of lactic acid using enriched beet molasses by Lactobacillus delbrueckii was investigated. The best yield was 62.6% while the conversion coefficient was 80.7 at 45C. Also, the highest yield and conversion coefficient obtained 81.4% and 58.7% respectively when using 12.62% sugars. Consequently, the best concentration could be around 18% total soluble solids. Optimum pH seemed to be around 6 since both yield and conversion percent was the highest. The optimum fermentation period, however; could be considered on the 8[th] day of fermentation, when maximum yield and conversion coefficient were obtained
