岳丰苹果制汁性能研究

Study on Juicing Performace of ‘Yuefeng’

以苹果新品种‘岳丰’果实为试材,进行制汁品质评价及浓缩汁加工比较试验。结果表明:鲜果可溶性糖含量12.98%、可滴定酸0.90%,果肉松脆,汁液多,微香,甜酸味浓。一榨、二榨的总出汁率为90%。超滤后色度值93%、透光度99.8%、浊度0.18 NTU。浓缩汁棕黄色,澄清透明,无异味,色度值80%、透光度96.5%、浊度0.83 NTU;总酸3.16%。稀释至可溶性固形物含量11.5%,果汁仍具有香气而无异味。表明‘岳丰’是一个优质的制汁品种。

The fruit juice of quality was evaluated and concentrated juice processing was compared in apple variety ‘Yuefeng’.The results showed that its flesh was crisp,juicy,sour-sweet,palatable,aromatic and normal taste,with soluble sugar content 12.98%,titration acid content 0.9%.The total juice rate of the first and the second was 90%.After the ultrafiltration,the juice was clear with a light transmittance of 99.8%,color value of 93%,turbidity of 0.18 NUT.The concentrated juice was brownish-yellow,clear and lucid,inoffensive,with a light transmittance of 96.5%,color value of 80%,turbidity of 0.83 NUT and total acid content of 3.16%.Dilute soluble solids content to 11.5%,juice still has the aroma and odorless.Yuefeng was a good quality variety of juice.
