以L808为试验菌株,研究了5~15 ℃、10~20 ℃、15~25 ℃和10~30 ℃(自然常温)4个温度区间香菇第1潮、第2潮、第3潮菇产品的水分、蛋白质、可溶性总糖变化。结果表明:4个出菇温度区间,普遍以第1潮菇含水量较低,可溶性总糖含量较高,随出菇潮次的增加,香菇产品的含水量逐渐增加,最大增幅0.90%。可溶性总糖含量逐渐降低,较低出菇温度区间(5~15 ℃)的降幅较小,第2、第3潮菇分别较第1潮菇降低7.50%和20.00%;较高出菇温度区间(15~25 ℃)的第2、第3潮菇分别较第1潮菇降低35.00%和45.00%。以第2潮菇蛋白质含量最高,较第1潮菇增加7.42%~8.58%,平均增幅8.05%;较第3潮菇增加7.52%~23.79%,平均增幅12.79%。

[Abstract]
L808, as the test stain, the product quality(include water, protein and soluble sugar content) change of Lentinus edodes at first, second and third tide under the influence of four temperature intervals(5~15 ℃, 10~20 ℃, 15~25 ℃ and natural room temperature) were studied in this work. The results showed that at every temperature intervals, water content of the first tide mushroom was generally low, but with a high soluble total sugar content. The water content increased with the fruiting tide with a maximum increase of 0.90%. The total soluble sugar content decreased gradually with the fruiting tide and the minimum drop appeared at the lower fruiting temperature interval of 5~15 ℃. Compared with the first tide mushroom, the total soluble sugar content decreased 7.50% and 20.00% for the second and third tidemushroom, respectively. The maximum drop appeared at the higher fruiting temperature interval of 15~25 ℃, and the total soluble sugar content decreased 35.00% and 45.00% for the second and third tide mushroom, respectively, compared with the first tide mushroom. The second tide mushroom shows highest protein content, which increased 7.42%~8.58%(average 8.05%) and 7.52%~23.79% (average 12.79%) compared with the first tide and third tide mushroom, respectively.
