Thermal degradation kinetics of ascorbic acid, thiamine and riboflavin in rosehip (Rosa canina L) nectar
Rosehip is a good source of some biologically active compounds. The main importance of rosehip is its high composition of vitamin C and rutin (vitamin P) and high content of pectins, fatty acids, sugars, organic acids, phenolic components, lycopene, carotene with activity of vitamin A and group B vitamins, tannins, carotenoids, minerals (particularly K and P) macroand microelements (Tuer & Russ...
متن کاملL-Ascorbic acid degradation by bacteria. VIII. All the pathway in the L-ascorbic acid metabolism.
The medium used contained 3g of substrate, 150ml of 1/15M phosphate buffer and 150ml of sterile distilled water. 0.5g (dry weight) of the adapted cells was added to the medium and the whole was incubated at 30•‹ for 20 hours. For detecting the intermediate products, paper chromatography was chiefly used. For developing the nonvolatile acids, n-butanol-acetic acid-water (4:1:1) was used and the ...
متن کاملThermal stability of L-ascorbic acid and ascorbic acid oxidase in broccoli (Brassica oleracea var. italica).
UNLABELLED The thermal stability of vitamin C (including l-ascorbic acid [l-AA] and dehydroascorbic acid [DHAA]) in crushed broccoli was evaluated in the temperature range of 30 to 90 degrees C whereas that of ascorbic acid oxidase (AAO) was evaluated in the temperature range of 20 to 95 degrees C. Thermal treatments (for 15 min) of crushed broccoli at 30 to 60 degrees C resulted in conversion ...
