摘要

随着对健康的关注,富含ω-3多不饱和脂肪酸的营养强化调味料的研发备受关注。该研究比较分析了添加纯鱼油和添加鱼油微胶囊对花生酱的理化特性及风味特性的影响。实验设置了空白对照组、鱼油组和微胶囊组,分别系统测定了花生酱的色泽、质构特性、流变特性、离心乳析率和氧化稳定性,并利用电子鼻进行风味分析。结果表明,微胶囊组的感官接受度优于鱼油组,但3组色泽差异不显著;微胶囊组具有适中的硬度和咀嚼性,较高的黏性和凝聚性,有助于抑制油酱分离;在流变特性方面,鱼油组可能有更好的涂抹性,但微胶囊组在离心乳析率(8.45% vs 10.83%)和氧化稳定性(32.77 h vs 30.11 h)方面均显著优于鱼油组。电子鼻检测结果显示,微胶囊和鱼油的添加可能掩埋了部分原有的花生香气。微胶囊化可通过控释机制缓解风味冲突,但仍无法彻底消除鱼油添加对花生酱基质原有香气体系的干扰。综上所述,与直接添加鱼油相比,添加鱼油微胶囊能更有效地改善花生酱稳定性、质构特性和整体感官风味。该研究可为ω-3营养强化食品的开发提供参考依据。

Abstract

With the growing emphasis on health and functional nutrition, ω-3 nutrition-fortified seasonings have attracted considerable attention.This study aimed to evaluate the effects of adding pure fish oil and microencapsulated fish oil on the physicochemical and flavor characteristics of peanut butter.A blank control, fish oil group, and microcapsule group were established to assess the color parameters, texture properties, rheological properties, oil separation rate under centrifugation, and oxidative stability, respectively.In addition, an electronic nose was used to analyze the flavor profiles of different samples.The results showed that the microcapsule group achieved higher sensory acceptability than the fish oil group.No significant differences in color were observed among the three formulations.Microcapsules improved texture properties by providing moderate hardness and chewiness, as well as higher viscosity and cohesiveness.These properties effectively suppressed oil-paste separation.Although the fish oil group exhibited slightly better spreadability, the microcapsule group showed a markedly lower oil separation rate under centrifugation(8.45% vs 10.83%) and better oxidative stability (32.77 h vs 30.11 h).Electronic nose analysis revealed that both microcapsules and fish oil partially masked the intrinsic peanut aroma.Microcapsules helped mitigate flavor interference through a controlled release mechanism, although they could not completely eliminate it.In conclusion, compared with direct fish oil addition, microencapsulated fish oil significantly enhanced the physicochemical stability, textural properties, and overall sensory quality of peanut butter.These findings provide a useful reference for the development of ω-3 nutrient-fortified food products.
