Affected by micro-organisms and endogenous enzymes, fish are highly perishable during storage, processing and transportation. Efficient evaluation of fish freshness to ensure consumer safety and reduce raw material losses has received an increasing amount of attention. Several of the conventional freshness assessment techniques have plenty of shortcomings, such as being destructive, time-consuming and laborious. Recently, various sensors and spectroscopic techniques have shown great potential due to rapid analysis, low sample preparation and cost-effectiveness, and some methods are especially non-destructive and suitable for online or large-scale operations. Non-destructive techniques typically respond to characteristic substances produced by fish during spoilage without destroying the sample. In this review, we summarize, in detail, the principles and applications of emerging approaches for assessing fish freshness including visual indicators derived from intelligent packaging, active sensors, nuclear magnetic resonance (NMR) and optical spectroscopic techniques. Recent developments in emerging technologies have demonstrated their advantages in detecting fish freshness, but some challenges remain in popularization, optimizing sensor selectivity and sensitivity, and the development of algorithms and chemometrics in spectroscopic techniques.

“…Authors used unsupervised and supervised MVSA to monitor the compositional changes induced during 2 weeks of storage at 0 and 4°C. Fish freshness has been also examined with NMR (Tan, Huang, Feng, Li, & Cai, 2018), however, only supervised MVSA was used in this study. In another study, 1 H NMR-based metabolomics was used to evaluate parameters associated with the quality of beef (Kodani, Miyakawa, Komatsu, & Tanokura, 2017).…”

Nuclear magnetic resonance (NMR) spectroscopy is a robust method, which can rapidly analyze mixtures at the molecular level without requiring separation and/or purification steps, making it ideal for applications in food science. Despite its increasing popularity among food scientists, NMR is still an underutilized methodology in this area, mainly due to its high cost, relatively low sensitivity, and the lack of NMR expertise by many food scientists. The aim of this review is to help bridge the knowledge gap that may exist when attempting to apply NMR methodologies to the field of food science. We begin by covering the basic principles required to apply NMR to the study of foods and nutrients. A description of the discipline of chemometrics is provided, as the combination of NMR with multivariate statistical analysis is a powerful approach for addressing modern challenges in food science. Furthermore, a comprehensive overview of recent and key applications in the areas of compositional analysis, food authentication, quality control, and human nutrition is provided. In addition to standard NMR techniques, more sophisticated NMR applications are also presented, although limitations, gaps, and potentials are discussed. We hope this review will help scientists gain some of the knowledge required to apply the powerful methodology of NMR to the rich and diverse field of food science.

“…The results showed that the transverse relaxation time T 2 was significantly correlated with moisture index ( p < .05) and freshness index (TVB N, K value, and TVC), and the LF‐NMR could be used to evaluate the changes of fish freshness during the cold chain logistics. Tan, Huang, Feng, Li, and Cai (2018) used high‐field nuclear magnetic resonance (HF‐NMR) to obtain data on the content of 21 metabolites during spoilage of zebrafish. After analysis by pattern recognition, the results indicated that acetate accumulation and lactate depletion could be used as indicators for fish freshness assessment.…”

As one of the vital food, aquatic products help to improve diet structure and alleviate food pressure. Aquatics food has a tender taste, with protein, polyunsaturated fatty acid (PUFA), and other nutrients. At the same time, aquatic products are highly susceptible to spoilage due to their properties in processing, transportation, and storage, which damages the economic efficiency of producers and may pose a threat to the dietary safety of consumers. Therefore, researchers have been working to developing an efficient, nondestructive, and practical technology to detect the freshness of aquatic products in real-time and easily. This article describes the representative techniques applied in recent years for the nondestructive inspection of aquatic products' freshness in terms of working principles, application examples, and characteristics. It summarizes each technique's development prospects and challenges.
