研究了酱香型白酒生产酒醅堆积过程的温度变化规律,并将温度变化与细菌和酵母数量变化结合分析,确定温度变化和微生物发酵的阶段变化之间存在一定规律。结果表明,微生物大量繁殖产生热量导致堆积醅温度的升高,所以酒醅温度的变化滞后于微生物数量的变化;堆积醅温度的升高在一定程度上对微生物的生长起作用,堆上层温度升高到一定温度后,微生物数量会下降;酒醅入窖后,温度在前几天快速升高,随后缓慢下降,前期主要是酒精的主要产生阶段,中后期主要是微量成分的酯化合成阶段。

该研究通过自制营养液循环系统,设置系统运行和停止时间均为7.5min(T_1)、15min(T_2)、22.5min(T_3)、30min(T_4)4个处理,以静止营养液培养为对照(CK),研究不同营养液循环间隔时间对营养液环境指标及水培紫色小白菜根系形态学指标、脯氨酸、丙二醛含量、根系内源激素及根系细胞显微结构的影响,以探究营养液循环间隔时间对水培紫色小白菜根系生长的影响机理。结果显示:(1)第0～10天,CK的营养液溶解氧含量下降了3.5mg/L,T_1～T_4的溶解氧下降幅度基本一致,约下降了1.2mg/L,CK的营养液溶解氧下降速率约为T_1～T_4的3倍;营养液的循环间隔时间处理对营养液温度及离子总量无影响。(2)于处理后第10天,T_1～T_4处理的紫色小白菜根系总长度、根系表面积、根系平均直径等根系形态学指标均大于CK处理,且T_2、T_3较T_1、T_4的根系生长更优,说明一定范围的营养液循环间隔时间能促进根系生长。(3)CK的紫色小白菜根系脯氨酸和丙二醛含量最高,T_2在T_1～T_4营养液循环处理中脯氨酸和丙二醛含量均相对较高,T_4处理最低且二者均显著低于对照。(4)各处理10d后,紫色小白菜根系内源激素有显著差异,其中IAA和GA3含量变化一致,均为T_2>T_3>T_4>T_1>CK;ABA含量的大小顺序为CK>T_4>T_1>T_3>T_2,且T_2的ABA和ZR含量也基本处于最低水平。(5)细胞显微结构观察发现,T_1～T_4处理的根系横切面由内向外第3层皮层细胞数量、新生侧根距离根尖1cm处直径、维管束和木质部区域直径占根系直径的比例均显著高于对照,且3项指标均为T_2最大(30个、450μm、42.22%),说明T_2的根系长势最优。研究表明,营养液循环间隔时间为15min(T_2)能够显著改善营养液溶解氧含量,有效提高根系IAA和GA3含量、促进根系皮层细胞分裂、增加新生侧根直径以及维管束和木质部区域直径,从而使水培紫色小白菜根系生长最优。

为了明确总酚、总黄酮及植酸在柚果果皮和果肉中的分布与积累特征,以平和县15个柚品种为供试材料,分别于果实膨大期和成熟期取样,对果实不同部位(果皮和果肉)总酚、总黄酮及植酸相对含量和积累量进行分析。结果表明:蜜柚果实富含总酚和总黄酮,而植酸含量相对较低;总酚、总黄酮及植酸相对含量和积累量在果皮和果肉上存在显著的品种差异;果皮中总酚、总黄酮及植酸在平均相对含量和积累量上都显著高于果肉;不同生育期中,成熟期总酚及总黄酮(果皮和果肉)平均相对含量和积累量较膨大期升高,而植酸则呈现降低趋势。综上,柚果皮总酚及总黄酮积累量在成熟期表现最高,是良好的果皮深加工及酚类物质提取来源。研究结果可为柚果品质改良以及食品加工提供理论参考。
