Platycarya strobilacea

Preliminary Study on Artificial Regeneration of Platycarya strobilacea Stand;

化香植被的人工促进天然更新技术初步研究

A scion-producing nursery for 120 plus trees of Carya cathayensi was established by grafting the plus tree scions on Platycarya strobilacea stocks,and the survival rate,growth indices and the shoot numbers from the scions were investigated according to the diameter of the stocks one year later.

以野生化香为砧木,以120株初选优树枝条为接穗构建山核桃采穗圃,嫁接1年后,按砧木不同直径等级统计其生长量、成活率、分枝数等;并根据不同采穗时间和嫁接时天气情况统计嫁接成活率。

In the presence of alkaline soap as emulsifier and catalyst, hydrogenated rosin sucrose esters (HRSE) were synthesized by transesterification reaction of hydrogenated rosin ethyl ester and sucrose under the conditions of (125±1)℃,molar ratio of hydrogenated rosin ethyl ester to sucrose 1 ∶1, pressure 0.

090MPa及无溶剂的条件下,通过氢化松香乙酯与蔗糖的酯交换反应合成了氢化松香蔗糖酯(HRSE)。

The hydrogenated rosin (HR) and hydroxyethyl methacrylate (HEMA) based ester was synthesized in one step method.

用一步法制备了氢化松香与甲基丙烯酸β-羟乙酯(HEMA)酯化物,结果表明,以对苯二酚为阻聚剂,氧化锌为催化剂,用量为氢化松香的1%,反应温度240℃,氢化松香与HEMA的摩尔比为1∶1。

By analyzing a plenty of practical production data,suitable conditions for controlling the product color during the production of hydrogenated rosin are concluded to be super grade rosin as raw material,melting time 5h and melting temperature 130150,molten rosin flow rate 400L/h,reaction temperature 240250.

另外还应尽量减少反应系统中的CO、CO2、SO2、重金属离子的含量,避免有色油类和空气进入反应系统,最后对产品进行水蒸气蒸馏,能得到颜色较浅的氢化松香产品。

Stability of emulsion flavor and its evaluating methods;

乳化香精的稳定性及其评价方法

This paper described the emulsifying effectiveness of single emulsifiers such as Tween, SE and Span and their co- emulsifiers in sweet orange emulsion flavor through the orthogonal examination, and studied up the best combination of emulsifiers.

本文通过对蔗糖酯(SE)、吐温(T)和司盘(S)系列的单体以及复配在甜橙乳化香精中的乳化效果研究,并应用正交实验确定了复合乳化剂的最佳配比以及相关的工艺参数。

This thesis mainly described the emulsifying effectiveness of single emulsifiers such as Tween, SE and Span,including their co-emulsifiers in sweet orange emulsion flavor.

通过对乳化香精中使用的主要添加剂增重剂、乳化剂和增稠剂在甜橙乳化香精中单独和复配使用的效果研究 ,发现对甜橙乳化香精来说乙酸异丁酸蔗糖酯 (SAIB)和松香甘油酯 (EG)的增重效果较好 ;聚山梨酸酯 40 (T 40 ) ,蔗糖脂肪酸酯 1 5 (SE 1 5 )的乳化效果较好 ;实验中选用的增稠剂在一定条件下可以增加乳状液的黏度 ,但是并没有提高乳状液的稳定性。
