使用自行研制的纳米活性气调包装膜,选用新鲜采摘的菠菜,进行气调包装研究.测定保鲜膜的拉伸强度、透气率和透湿率,对菠菜包装的保鲜效果进行感官评价,研究随着分子筛含量的增加,菠菜失重率、可溶性固形物和呼吸强度的变化.结果表明:在室温下,Hβ-7保鲜膜的保鲜效果最好,气调保鲜包装的平衡气体浓度为O2含量13.4%~13.7%,CO2含量3.6%~4.2%.保鲜期可长达5 d;在保鲜柜中,Hβ-7保鲜膜的保鲜效果最好,气调保鲜包装的平衡气体浓度为O2含量19.8%~20.2%,CO2含量1.2%~1.4%,货架寿命可达10 d以上.

The study was carried out by using own-blowing nano active air modified packaging films and choosing new-pick spinach to examine the effects to fresh-keeping. The tensile strength, air and moisture permeability of the films were examined. The sensory evaluation of the fresh-keeping effect was made. With the increase of molecular sieve content, weight loss of spinach and changes in soluble solids and respiration rate were examined. The results show that at ambient conditions, the fresh-keeping effect of Hβ-7 film is the best, the balance air concentration in air modified package was O2 content of 13.4%~13. 7% and CO2 content of 3.6~4. 2%, and fresh-keeping time can reach 5 days. In fresh-keeping cabinet, the fresh-keeping effect of Hβ-7 film is best, the balance air concentration in air modified package was O2 content of 19.8%~20.20% and CO2 content of 1.2%~1.4%, and fresh-keeping time can reach more than 10 days.
