| The stability of stearyl chloride modified procyanidins oligomers from lotus seedpod (modified-LSOPC) in different environmental systems, such as acid, alkali, oxidant, reducing agent, anion and cation commonly found in food, and its potential effect on oil storage and meat preservation were studied.The results showed that modified-LSOPC could be stable in the presence of weak acid and low amount of reducing agent, but its structure was easily destroyed in the environment of strong acid, alkali and oxidant. At the same time, modified-LSOPC could maintain stable structure in most of the anion and cation, but changed easily in hydrolytic cations such as Fe2+, Fe3+ and Al3+ and acid radical ions such as CO2-3 and HCO-3. The modified-LSOPC showed better preservation effect in rapeseed oil and cooling pork than LSOPC during long-term storage. All results illustrated that the antioxidative abilities of modified-LSOPC in lipid-related systems were improved effectively. |
