Like cassava flour for making “attiéké” (cassava semolina), the sweet potato tuber, after grinding followed by pressing, produces flour and juice. The present work aims to enhance this juice from the sweet potato by a fermentation which leads to an alcoholic drink. The process consists of five steps including juice extraction, gelation, enzymatic hydrolysis by millet malt, pasteurization and fermentation. We have followed the evolution of some chemical and biochemical parameter at each step of the process. The results indicate that enzymatic hydrolysis with millet malt increases the reducing sugar level by 10 times which was 0.074 g/ml ± 0.013 and 0.041 mg/ml ± 0.011 respectively for white-fleshed sweet potato and yellow flesh after extraction. However, the process drops the vitamin C level from 0.1 mg / ml ± 0.013 of white-fleshed potato juice and 0.05 mg / ml ± 0.002 of yellow-fleshed potato juice to 6.6 10-3 mg/ml ± 1.9.10-3 and 5.9.10-3 mg / ml ± 0.8.10-3 in the same order. The optimal production of alcohol during fermentation is obtained with a concentration of 40 mg / L of yeast to reach an alcohol level of 5.56% ± 0.1 and 4.60% ± 0.1 respectively for the potatoes. sweet with yellow flesh and white flesh after 6 hours.

SummaryThe metabolism of vitamin K1- 14C and menadione-14C (vitamin K3-14C) was studied in normal and hepateetomized rats. After the administration of menadione, about 70% of the 14C was excreted in the urine in 24 hrs in both types of rats. Two urinary metabolites were identified by enzymatic hydrolysis: one a glucuronide and the other a sulfate of reduced menadione. Thus, the liver is not necessary for the metabolism of menadione. In the vitamin K1 studies, the intact rats excreted only 10% of the 14C and the hepatectomized rats excreted less than 0.5%. The retention of vitamin K1 may explain its superiority over menadione as an antidote for overdosages of oral anticoagulants.

This study investigates the use of pretreatment and enzymatic hydrolysis side streams and conversion to lignocellulose nanofibers. We used a steam-exploded and partial enzymatic hydrolyzed hardwood pulp and an organosolv pretreated softwood pulp to prepare lignocellulose nanofibers (LCNF) via microfluidization. The energies applied on fibrillation were estimated to examine the energy consumption levels of LCNF production. The energy consumptions of the fibrillation processes of the hardwood LCNF production and the softwood LCNF production were about 7040-14080 kWh/ton and 4640 kWh/ton on a dry material basis, respectively. The morphology and dimension of developed hardwood and softwood LCNFs and the stability and rheological behavior of their suspensions were investigated and are discussed.
