Sunflower oil with vitamin D: Preliminary investigation of enrichment possibility
Fat soluble vitamins, including vitamin D, are not sufficiently represented in the human diet. Although vitamin D can be synthesized in the body by direct exposure of the body to the sun, often people don’t get enough sun exposure to assure enough vitamin D. Previous research has established that vitamin D deficiency is considered to be a hig...

Conventional and ultrasound-assisted extraction of (poly)phenols from elderberry flowers Sambucus Nigra L.
In this paper, conventional solid-liquid extraction and ultrasound-assisted extraction were utilized for (poly)phenols extraction from black elderberry flowers. The extraction lasted 30 to 120 min, with a solid-to-solvent ratio of 1:15 w/v and 1:30 w/v and solvents of 30% and 60% ethanol. Total (poly)phenols, flavonoids and anthocyanins contents we...

XANTHAN PRODUCTION ON CRUDE GLYCEROL BY LAB-SCALE BIOREACTOR CULTIVATION OF LOCAL Xanthomonas ISOLATE
Intensive development of the global biodiesel industry has led to the generation of a large excess of crude glycerol, which is impure, and its disposal into the environment is unacceptable without previous purification. Since purification costs are high, the application of crude glycerol in biotechnological production of valueadded products represe...
