中文摘要: 通过对红心地瓜综合利用加工过程中,臭氧减菌和无硫护色工艺的单因素试验、正交试验和验证试验,检测地 瓜片的菌落总数和对制得的地瓜干成品进行感官评分,结合生产实际“臭氧减菌-无硫护色”最佳工艺为:臭氧水浓度 0.8 mg/L,处理时间 11 min,臭氧水温度 15 ℃;处理时间 8 min,D-异抗坏血酸钠浓度为 0.1 %,柠檬酸浓度为 0.1 %。在此 条件下,制得的地瓜干各项指标均符合产品要求,味道清香甜美,质地松软。

Abstract:Through of sweet potato processing, the single factor test, orthogonal test and verification test of o- zone reduction bacteria and sulfur free color protecting techniques were studied, and the total number of colonies and sensory score of sweet potato products chips were detected.Combined with the actual production of “ozone reduction bacteria without sulfur color protection”,the best technology was got: ozone water concentra- tion 0.8 mg/L, the processing time 11min, ozone water temperature of 15 ℃; treatment time 8min, sodium D-isoascorbate concentration of 0.1 %, citric acid concentration of 0.1 %. Under these conditions,each index of dry potatoes all conformed to product requirements.
