麻辣火锅底料辣度标准化及李氏辣度研究

Research on the Standardization of Pungency Degree of Spicy Hotpot Seasoning and Li Spicy Unit

研究麻辣火锅底料辣度的分级方法,将消费者的辣度等级评定意见与麻辣火锅底料中辣味主要成分辣椒素类物质含量结合划分辣度等级,将辣度等级分为微辣、低辣、中辣、高辣、特辣、暴辣6个,使用高效液相色谱仪(荧光检测器)检测麻辣火锅底料中辣椒素类物质的含量,各辣度等级对应的辣椒素含量为:0.00509~0.0164,0.0389~0.0962,0.0940~0.189,0.201~0.789,0.596~1.351,1.895~5.323g/kg。参考众所周知的酒精度各低、中、高度酒的代表度数,取12°代表微辣,36°代表低辣,45°代表中辣,52°代表高辣,65°代表特辣,75°代表暴辣,麻辣火锅底料的辣度命名为"李氏辣度",各辣度等级辣椒素类物质含量(W)换算成李氏辣度(LSU)的公式为:LSU=10.369ln(W)+65.264,相关系数R2为98.17%,并划定微辣为9°~29°,低辣为30°~39°,中辣为40°~49°,高辣为50°~59°,特辣为60°~69°,暴辣为≥70°。将不容易被消费者认知的辣椒素类物质含量换算成便于消费者理解的度数,可以使消费者更能理解和选择适合的辣度。

The classification method of pungency degree of spicy hotpot seasoning is studied.The grade of pungency degree is divided by the consumers＇ opinions of the spicy rating and the capsaicin substances in spicy hotpot seasoning,and it includes 6 grades,such as slightly spicy,low spicy,medium spicy,high spicy,super spicy,explosive spicy.The content of capsaicins in spicy hotpot seasoning is detected by high performance liquid chromatograph（fluorescence detector）,and the content of capsaicins corresponding to each pungency degree is：0.00509-0.0164,0.0389-0.0962,0.0940-0.189,0.201-0.789,0.596-1.351,1.895-5.323 g/kg.Reference to the well-known alcohol degree＇s representative degrees of low,medium and high,and 12°for slightly spicy,36°for low spicy,45°for medium spicy,52°for high spicy,65°for super spicy,75°for explosive spicy,the pungency degree of hotpot seasoning is named as ＂Li Spicy Unit＂,and the formula to convert each pungency degree＇s capsaicin content into Li Spicy Unit is LSU=10.369 ln（W）＋65.264,the correlation coefficient R2 is 98.17%,and each pungency degree is slightly spicy for 9°-29°,low spicy for 30°-39°,medium spicy for 40°-49°,high spicy for 50°-59°,super spicy for 60°-69°,explosive spicy for≥70°.Converting the capsaicin content that is difficult to be recognized by consumers into alcohol degree that is easy for consumers to understand,it can make consumers better understand and choose the appropriate pungency degree.
