Abstract:
Cistanche deserticola planted in Xinjiang was used as the test material, and the effects of the active modified atmosphere treatment (6% CO2+4% O2+90% N2) combined with different packaging materials PE film (oxygen permeation 300 cm3/(m2•d)), microporous membrane M1 (oxygen permeation 6,000 cm3/(m2•d)) and microporous membrane M2 (oxygen permeation 8,000 cm3/(m2•d)) on the changes of active components and antioxidant activities of the fresh-cut Cistanche deserticola stored at a low temperature, (4±0.5)℃. The results showed that after 7 days of storage, the PPO activity and browning degree for the group treated with modified atmosphere microporous membrane (6% CO2+4% O2+90% N2+M1) were 2.07 U/g and 0.57 OD410/g, respectively, which were lower than those of the CK group. The contents of Vc, total phenolics, flavonoids, total polysaccharides, echinacoside and calycoside were 13.00%, 5.88%, 11.24%, 14.45%, 1.20% and 1.47%, respectively, higher than those of the CK group. The DPPH and ABTS+ free radical scavenging rates and FRAP value for the group treated with 6% CO2+4% O2+90% N2+M1 microporous membrane were 8.97%, 1.99% and 11.43%, respectively, higher than those of the CK group. Accordingly, the 6% CO2+4% O2+90% N2+M1 treatment could significantly retard the decrease of the active components of the fresh-cut C. deserticola, and maintain its high antioxidant capacity and slow down its senescence, thereby maintaining better the medicine and food homology of fresh-cut C. deserticola. This would be a good preservation method for fresh-cut C. deserticola.
