摘要: 探究超声波、冻融循环一次、超声波+冻融循环一次、冻融循环两次和超声波+冻融循环两次预处理对鸡油菌真空冷冻干燥效率和品质的影响。结果表明,预处理显著缩短鸡油菌真空冷冻干燥的时间(6.25%~37.50%),同时提高总黄酮含量、总酚含量,并增强其抗氧化能力。其中,超声波+冻融循环一次预处理使鸡油菌干燥时间缩短37.50%,表现出最高的总酚((2.79±0.02)mg/g)、总黄酮((7.94±0.07)mg/g)含量和较强的抗氧化能力,且降低苦味游离氨基酸含量的同时保持了较高的总游离氨基酸含量。以上结果表明,这些预处理方法均能提高鸡油菌真空冷冻干燥的干燥效率和冻干鸡油菌的品质,且超声波+冻融循环一次预处理辅助真空冷冻干燥技术可有效制备高品质鸡油菌干制品。

Abstract: This study examined the effects of five pretreatment methods namely ultrasound (US), one freeze-thaw cycle (FT-1), ultrasound combined with one freeze-thaw cycle (US + FT-1), two freeze-thaw cycles (FT-2), and ultrasound combined with two freeze-thaw cycles (US + FT-2) on the vacuum freeze drying (VFD) efficiency and quality attributes of Cantharellus cibarius. The results demonstrated that all pretreatments reduced the drying time (6.25%–37.50%) while increasing the total flavonoid (TFC) and total phenolic contents (TPC) and enhancing the antioxidant capacity. US + FT-1 reduced the drying time by 37.50% and resulted in the highest TFC ((2.79 ± 0.02) mg/g) and TPC ((7.94 ± 0.07) mg/g) and strong antioxidant activity. Additionally, this treatment reduced the bitter amino acid content while preserving high total amino acid levels. These findings indicate that all tested pretreatments improve the drying efficiency and quality of VFD-dried C. cibarius, with US + FT-1 being particularly effective for producing high-quality dried C. cibarius.
