Abstract

Optimization of important drying parameters with PEF pretreatment was carried out using Hermetia illucens larvae tissue. Three level factorial design of response surface methodology was used for the study varying specific PEF energy input 10–20 kJ/kg and drying temperature of 50–90 °C. Important average H. illucens larvae temperature during the drying process was obtained by numerical simulation from Luikov drying model. Consumption of drying energy was affected more by the drying temperature, than by the PEF energy. This indicated that range between 81 and 84 °C drying temperature and range from 11.2 to 13.1 kJ/kg of specific PEF energy input may be considered as optimal processing window for larvae drying.

摘要

使用Hermetia illucens幼虫组织对重要的 PEF 预处理干燥参数进行了优化。响应面方法的三级因子设计用于研究不同的特定 PEF 能量输入 10-20 kJ/kg 和 50-90 °C 的干燥温度。通过 Luikov 干燥模型的数值模拟，获得了干燥过程中重要的H. illucens幼虫平均温度。干燥能量的消耗受干燥温度的影响比受 PEF 能量的影响更大。这表明 81 至 84 °C 的干燥温度范围和 11.2 至 13.1 kJ/kg 的特定 PEF 能量输入范围可被视为幼虫干燥的最佳处理窗口。
