摘要
目的:研究灵芝孢子破壁的工艺,提高灵芝孢子粉破壁率。方法:以灵芝孢子粉的含水量和影响破壁的硬度为指标,选取脆化温度、抽空干燥温度、抽空干燥时间为考察因素,采用L9(34)正交设计优选变温压差脆化条件;制得的脆化样品与超微粉碎进行破壁率比较。结果:最佳脆化条件为脆化温度100℃,抽空干燥温度80℃,抽空干燥时间1 h。在此条件下,灵芝孢子粉含水量3.0%,破壁硬度3.7 kg。脆化、干燥后的灵芝孢子粉经超微粉碎50 min,破壁率可达99.5%。结论:变温压差脆化结合超微粉碎技术可提高灵芝孢子破壁率。
Objective： To study on wall-broken technology of Ganoderma lucidum and increase broken rate of G. lucidum powder. Method： According to index of moisture content and breaking hardness of G. lucidum powder, effect of embrittlement temperature, vacuum drying temperature and vacuum drying time on embrittlement conditions with different temperature and pressure were studied by L9 （34） orthogonal experiment. And embrittlement ratio of prepared embrittlement sample and superfine grinding sample were compared. Result： It was found that optimum embrittlement conditions were： embrittlement temperature, vacuum drying temperature and , vacuum drying time were 100 ℃, 80 ℃ and 1 h, respectively. Under these conditions, the moisture content and breaking hardness were 3.0% and 3.7 kg. After embrittled and dried, G. lucidum powder was broken 50 min, broken rate of G. lucidum was up to 99.5%. Conclusion： Bbroken rate of G. lucidum could enhance by combining difference temperature and pressure embrittlement and superfine grinding technology.
