[Objective]The quality and aroma characteristics of macadamia brewing wine were clarified to provide a technical support for comprehensive utilization of macadamia nuts and by-products.[Method]The physicochemical quality indexes including alcohol content,total acid content,total ester content,solid content and ethyl hexanoate content of macadamia brewing wine and base liquor were determined.The aroma,key aroma substances and quality of macadamia brewing wine and base liquor were analyzed,measured and quantitatively described by HS-SPME-GC-MS,ROAV and sensory evaluation respectively.[Result]All tested items of the base liquor accorded with the standards of Jiang-flavour Chinese Spirits(GB/T 26760-2011),and all tested items of macadamia brewing wine accorded with the standards of National Food Safety Standard Distilled Liquor and Its Blended Liquor(GB 2757-2012)also.48 and 42 volatile aroma substances were detected in macadamia brewing wine and base liquor and their relative content was 86.77%and 92.59%,respectively.The relative content of esters in macadamia brewing wine and base liquor was 41.80%and 56.61%respectively.The relative content of alcohols in macadamia brewing wine and base liquor was 26.57%and 14.37%respectively.There were five key aroma substances of ethyl hexanoate,ethyl butyrate,ethyl valerate,ethyl heptanoate and ethyl octanoate in macadamia brewing wine.There were five key aroma substances of ethyl hexanoate,ethyl valerate,ethyl heptanoate,ethyl octanoate,and ethyl isovalerate in the base liquor.Macadamia brewing wine and base liquor both presented the typical style characteristics of Jiang-flavour Chinese spirits,and the brewing wine from the base liquor added with macadamia nuts and shells was of obvious nut flavor.[Conclusion]All tested items of macadamia brewing wine accord with the standard requirements of National Food Safety Standard Distilled Liquor and Its Blended Liquor(GB 2757-2012).5 key aroma substances of ethyl hexanoate,ethyl butyrate,ethyl valerate,ethyl heptanoate,and ethyl octanoate in macadamia brewing wine jointly give the special flavor of sweet and fruity and typical characteristics of a sauce-flavored liquor with obvious nutty aroma.Macadamia brewing wine can be popularized as the wine with regional characteristics.
