摘要
为探究不同干燥方式、不同存储温度和存储时间对羊栖菜中岩藻黄素稳定性的影响,本研究考察了三种不同干燥方式,包括自然阴干、低温烘干和冷冻干燥,对羊栖菜中岩藻黄素稳定性的影响。结果表明采用冷冻干燥所得羊栖菜,含水量低,岩藻黄素含量高,达到699.2μg/g,岩藻黄素保留率为94.7%,远高于自然阴干及低温烘干。因此,冷冻干燥是最佳干燥方法。考察了四个不同温度(-20、4、25、30℃)存储对冻干羊栖菜中岩藻黄素稳定性的影响,结果表明随着存储温度的升高,岩藻黄素的降解率明显增高,因此,-20℃为最佳储存温度。
This study investigated the effects of different drying methods,storage temperatures and stored time on the stability of fucoxanthin from Sargassum fusiforme .Effects of three different drying methods (air-dried in the shade at room temperature,low-temperature drying method and vacuum freeze drying method) on the stability of fucoxanthin from S.fusiforme were discussed.The results showed that compared with low-temperature drying method and air-dried in the shade at room temperature,vacuum freeze drying method was the best drying method due to S.fusiforme treated with this method had lower moisture content,higher content of fucoxanthin (699.2 μg/g) and higher retention of fucoxanthin (94.7%).In exploring the effects of different temperatures (-20 ,4,25,30 ℃) on fucoxanthin from S.fusiforme ,the results showed that the degradation rate of fucoxanthin was obviously increased with the increase of storage temperatures.Therefore,-20 ℃ was the best storage temperature for S.fusiforme .
