摘要

目的:筛选象皮石粉熨烫工艺参数，分析象皮石粉熨烫前后的蛋白质和氨基酸含量。方法:以粉碎率和醇溶性浸出物为评价指标，采用L9(34)正交试验法考察煮沸温度、煮沸时间和搅拌速度。用凯氏定氮法和氨基酸分析仪测定象皮草中蛋白质和氨基酸的含量。结果:最佳加工工艺参数为:每100 kg象力石中加入滑石粉30 kg，加工温度350 ~ 380℃，搅拌速度15 r / min，加工3 min，加工前后象力石均含有16种氨基酸。粗象石中蛋白质含量为92。4%，总氨基酸含量为62。79%;加工后的象皮中蛋白质含量为98。2%，总氨基酸含量为67。在不考虑含水率的情况下，与粗油相比差异不显著。结论:所选滑石粉熨象皮工艺稳定，重现性好。

[Study on Talcum Powder Ironing Process of Corium Elephatis and Analysis Content of Amino Acid Before and After Processing].

Objective: To screen the talcum powder ironing process parameters of Corium Elephatis, and to analyze the contents of protein and amino acids in Corium Elephatis before and after processing.

Methods: Take the crushing rate and alcohol-soluble extractive as evaluation indexes, investigating the boiling temperature, boiling time and stirring speed with the L9（ 34） orthogonal test method. Determine the contents of protein and amino acid in Corium Elephatis by Kjeldahl method and amino acid analyzer.

Results: The optimal processing technology parameters were as follows: In 100 kg Corium Elephatis it should be added 30 kg talcum powder, the processing temperature was 350 380 ℃,with stirring speed of 15 r / min processing for 3 min. Both Corium Elephatis before and after processing had 16 kinds of amino acids. In crude Corium Elephatis, the content of protein was 92. 4%,and the total content of amino acids was 62. 79%; while in processed Corium Elephatis, the content of protein was 98. 2%,and the total content of amino acids was67. 03%,those had no significant difference commpared with the crude one when ignoring the water content.

Conclusion: The selected talcum powder ironing process of corium elephatis is stable with good reproducible.
