Anti-Mildew Effects of High Performance Barrier Films on Fresh Steam-Flake Corn during Storage
摘要
Abstract
In this test, we stored fresh steam⁃flaked corn with general plastic films and high performance barri⁃er films ( HPBF) , and determinate the degree of mildew at different storage time points to discuss the feasibili⁃ty of using the HPBF to store fresh steam⁃flaked corn. Taking the general plastic films, but not seal, store fresh steam⁃flaked corn as the unseal general plastic films ( USGPF ) group; the sealed general plastic films store fresh steam⁃flaked corn as the general plastic films ( SGPF ) group; and the sealed HPBF store fresh steam⁃flaked corn as the HPBF group. After storing 0, 7, 14, 21, 28, 42 and 56 days, the sensory evaluation, chemical component, fatty acid value and the content of aflatoxin B1(AFB1), zearalenone (ZEA) and de⁃oxynivalenol ( DON) were determined. The results showed as follows:1) with extension of storage time, the USGPF group and SGPF group appeared mildew phenomenon in succession, but the HPBF group did not ap⁃pear mildew phenomenon after stored 56 days. 2) With the increased of storage days, the ether extract, soluble starch content and starch gelatinization showed a decreasing trend among different films treatment, but there were no significant differences in the contents of ash, crude protein, neutral detergent fiber, acid detergent fi⁃ber (P>0.05). 3) The store time had extremely significant effect on fatty acid value (P<0.01). Compared with the other groups, the growth of the HPBF groups’ fatty acid value was slower, and its fatty acid value was 10.54 mg/kg after storing 56 days. 4) During the storage, the AFB1 and ZEA content kept on increasing with the store time ( P<0.05) , but there were no significant change in the content of DON during the storage (P>0.05). After storing 56 days, the AFB1, ZEA and DON content of the USGPF group, SGPF group and HPBF group were 1.03, 0.73, 0.01μg/L and 181.13, 170.49, 148.19μg/L and 1.23, 1.23, 1.20μg/mL, respectively. In conclusion, the HPBF can inhibit the growth of mildew, slow fatty defeat, and safety storage the fresh steam⁃flaked corn for 56 days.关键词
