成果简介

相较于传统热加工技术,食品工业中新型非热技术的应用主要是基于其实现酶钝化和微生物失活以延长货架期,且同时不显著改变食品感官属性和营养活性,但不同食品基质条件下越来越多的证据表明,维持加工过程中微生物/酶钝化效率与感官-营养特征之间的平衡仍然面临挑战。因此,有必要总结和阐明非热条件下食品质量参数的响应规律及机制。








本文选取高静压(HHP)非热条件下挥发性风味物质演变作为考察体系,主要基于如下两个原因:(1HHP技术是最具代表性的一种新型非热技术,目前已在多个食品基质中实现商业化应用,如奶制品和果蔬等。(2)挥发性风味物质由小分子构成,在常规HHP处理压力范围内共价键压缩性可忽略,不直接破坏风味组分结构,因而与脉冲电场、低温等离子体等非热方式不同(如容易诱发自由基形成影响挥发性物质);高压由于处理时间较短,热效应不显著,其一般不显著介导小分子的化学变化过程,因而该技术较长一段时间内被认为不改变食品风味特征。但近期多份研究开始证实高压具有显著影响食品挥发性风味组变迁的能力。在总结归纳典型食品基质高压处理过程挥发性风味组响应的基础上,结果表明,HHP可通过多种方式改变食品基质顶空挥发组构成和浓度分布,涉及酶促生化反应、物理包埋与释放以及化学动力学以及微生物代谢过程等具体因素,与食品基质类型和加工参数相关联;同时发现,HHP可诱导或强化特定挥发性风味物质的生成途径,如美拉德反应与脂解等。全面解析高压非热条件下挥发组响应规律与过程参数之间的定性定量关系及相关机理,不仅有助于协同调控加工过程中食品质量参数,还可将HHP发展为一种定向改造食品风味特征的全新技术。

Abstract

Nonthermally driven volatilome evolution of food matrices: The case of high pressure processing

Background

The adoption of innovative nonthermal processing as alternatives to conventional heating techniques in the food industry is mainly relied on their tremendous potential to simultaneously achieve preservation purposes and the maintenance of fresh-like characteristics and health benefits of final products. With increasing evaluation for the applicability of nonthermal processing, there remains, however, a great challenge for keeping the balance between the efficiency of microbial/enzymatic inactivation and the maintenance of sensory and nutritional characteristics. Accordingly, a timely summarization and elucidation of the response pattern and mechanism of related quality parameters under nonthermal conditions is of great importance.

Scope and approach

In this review, the nonthermal effects of high pressure processing (HPP) on volatilome evolution are discussed, considering its close relationship with food flavor quality. It starts with elucidating the pressurization principles linked to volatilome evolution. Then, the general volatile fingerprinting features responding to HPP in major food items are summarized, followed by the analysis of the response mechanisms behind. Finally, the potential of innovative applications based on HPP-induced volatilome evolution is discussed.

Key findings and conclusions

A critical examination of newly updated findings has suggested the non-negligible spatiotemporal HPP effects on the headspace volatile fingerprinting and flavor perception of pressurized foods. HPP-induced volatilome evolution results from the biochemical, physical, and chemical as well as metabolic effects of high pressure, and specific mechanisms depend on the features and manufacturing crafts of sample matrices, process variables and processing patterns. HPP shows its great potential as an aroma modification and flavor-tailoring technique, based on a comprehensive understanding of the mechanistic and quantitative relationship between volatilome evolution and process parameters.
