Effect of targeted enzymatic hydrolysis on flavor characteristics and volatile organic compounds of Ruditapes philippinarum cooking liquid
[目的]高值化利用杂色蛤加工副产物.[方法]以杂色蛤蒸煮液为原料,基于前期实验定向酶解工艺制备酶解呈味基料,以 TCA 可溶性肽、游离氨基酸(FAA)、呈味核苷酸和有机酸含量、滋味活性值(TAV)、等效鲜味浓度(EUC)、呈味强度(TI)等指标综合评价风味特征,并结合电子舌、电子鼻、气相色谱-离子迁移谱(GC-IMS)解析挥发性有机化合物(VOCs)的演变规律.[结果]定向酶解能显著提高 TCA 可溶性肽、FAA、呈味核苷酸等关键呈味物质的含量(P<0.05);酶解呈味基料中谷氨酸的TAV 由4.71 显著增加到11.74(P<0.05),EUC 由1.46 g MSG/100 g 增加至5.31 g MSG/100 g,TI 约为杂色蛤蒸煮液的 3.6 倍;电子舌显示酶解呈味基料的鲜味和浓厚感明显增强,电子鼻-PCA 显示酶解前后蒸煮液的气味强度差异明显,定向酶解有效改变了酶解前后的挥发性风味轮廓;GC-IMS 共定性72 种 VOCs,酶解后蒸煮液中酯类、醛类、酮类、呋喃类等风味物质的含量明显增加,而异丁醇、三乙胺等不良风味物质含量明显降低.[结论]定向酶解不仅能提升杂色蛤蒸煮液的鲜味品质,还能赋予其果香-脂香复合的多元风味特征.
[Objective]To achieve the high-value utilization of processing by-products from Ruditapes philippinarum.[Methods]With Ruditapes philippinarum cooking liquid as raw material,the enzymatic flavor base was prepared via the targeted enzymatic hydrolysis process optimized in our previous study.The flavor characteristics were comprehensively evaluated based on multiple indicators,including the contents of TCA-soluble peptides,free amino acids(FAA),flavor nucleotides and organic acids,as well as taste activity value(TAV),equivalent umami concentration(EUC)and taste intensity(TI).Combined with electronic tongue and electronic nose,gas chromatography-ion mobility spectrometry(GC-IMS)was adopted to analyze the evolution of volatile organic compounds(VOCs).[Results]Targeted enzymatic hydrolysis significantly increases the contents of key flavor substances such as TCA-soluble peptides,FAA and flavor nucleotides(P<0.05).In the enzymatic flavor base,the TAV of glutamic acid increases significantly from 4.71 to 11.74(P<0.05),the EUC rises from 1.46 g MSG/100 g to 5.31 g MSG/100 g,and its TI is approximately 3.6 times that of the original Ruditapes philippinarum cooking liquid.Electronic tongue analysis shows that the umami and richness of the enzymatic flavor base are significantly enhanced.Electronic nose-PCA reveals remarkable differences in odor intensity of the cooking liquid pre-and post-enzymatic hydrolysis,confirming that targeted enzymatic hydrolysis effectively alters its volatile flavor profile.A total of 72 VOCs are qualitatively identified by GC-IMS.The contents of flavor substances such as esters,aldehydes,ketones and furans in the enzymatic flavor base increase significantly,while the contents of undesirable flavor substances like isobutanol and triethylamine decrease obviously.[Conclusion]Targeted enzymatic hydrolysis can not only improve the umami quality of Ruditapes philippinarum cooking liquid,but also endow it with diverse composite flavor characteristics of fruity and fatty aromas.
