【摘要】：为了探究不同产地寒富苹果品质和贮藏性的差异,分别以沈阳东陵和珲春孟岭两个产地的寒富苹果为实验材料,探究两个产地的苹果果实在贮藏中品质及其贮藏性的变化。实验结果表明:在果实品质方面,相比于珲春产果实,沈阳产果实果肉较致密,果皮较薄,果皮光泽度显著高于珲春产果实;可溶性固形物含量较高,可滴定酸含量下降较晚,在贮藏后期果实硬度较大,但是贮藏后期果实失重率增加较快;在果实贮藏性方面,两产地果实总果胶含量变化趋势相似,珲春产果实纤维素含量比沈阳产果实纤维素含量提前30 d达到峰值;珲春产果实半纤维素含量在贮藏60 d后下降迅速;二者PG酶活性变化趋势相似,但是珲春产果实β-Gal酶活性在贮藏60 d达到峰值,比沈阳产果实β-Gal酶活性提前30 d达到峰值。综上所述:相比于珲春产果实,沈阳产寒富苹果果实品质较好,耐贮性较强。
[Abstract]:In order to explore the difference of quality and storage property of cold rich apple from different producing areas, cold rich apple from Shenyang Dongling and Hunchun Mengling were used as experimental materials. The changes of fruit quality and storage property of apple fruits from two producing areas were investigated. The results showed that compared with Hunchun fruits, Shenyang had denser pulp and thinner pericarp than those from Hunchun. The luster of pericarp was significantly higher than that of Hunchun fruit, the content of soluble solids was higher, the content of titratable acid decreased later, the firmness of fruit was larger in the later period of storage, but the weight loss rate of fruit increased rapidly in the later period of storage, and in the aspect of fruit storage, The change trend of total pectin content was similar, the cellulose content of Hunchun fruit reached its peak 30 days earlier than that of Shenyang fruit, and the hemicellulose content of Hunchun fruit decreased rapidly after 60 days of storage. The change trend of PG enzyme activity was similar, but the 尾 -Gal enzyme activity of Hunchun fruit reached its peak after 60 days storage, which was 30 days earlier than that of Shenyang fruit. In conclusion, compared with Hunchun fruit, the 尾 -Gal enzyme activity of Hunchun fruit reached its peak. The fruit quality of cold rich apple in Shenyang is good and the storage ability is strong.
