Since its initial studies in the late 1940s, there were solutions that were put forward to address, such as using mechanical holders to contain the inner pressure of the package with food materials, use of fluids instead of mechanical holders, use of strong containers or polymeric packages, and use of monolayer and multilayer packaging. But even all these solutions could not entirely solve the problem of non-uniform heating. After the 2000s, the rise in numerous numerical simulations and modelling software, opened the doors to further explore this field of research with more details and to numerically model the multi-physics phenomenon. However, studies have still not been sufficient to commercially deploy microwave sterilization systems to their full potential. Challenges such as temperature measurement, pressure measurement and control, usage of the right packaging material, and homogeneous heat distribution are still to be addressed, all while developing an energy-efficient process using numerical modelling and simulation tools. Hence, this review aims to study the microwave sterilization systems since the early days of research and the packaging aspect during the microwave sterilization process. The review also explores the potential held by the numerical simulation and modelling tools in this field of microwave sterilization.</p></div>","PeriodicalId":565,"journal":{"name":"Food Engineering Reviews","volume":"16 2","pages":"192 - 224"},"PeriodicalIF":5.3,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140169958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, there is growing realization that inactivation kinetics and the individual microbes’ spectrum of vulnerabilities or resistances to a lethal agent are two sides of the same coin. This creates the possibility to convert traditional survival data plotted on linear or semilogarithmic coordinates to temporal distributions of the individual microbes’ deactivation, or vice versa. Such conversions are demonstrated with simulated microbial survival patterns generated with different kinds of survival models: the two-parameter Weibull distribution of which the single-parameter loglinear model is a special case, the normal, lognormal, and Fermi distribution functions, which imply that complete microbial inactivation is theoretically impossible, the three-parameter Gompertz survival model which allows for definite residual survival, and the three-parameter version of the beta distribution function, allowing for a definite thermal death time beyond which no survivors will ever be found. Also provided are simulated examples of the survival patterns of mixed microbial populations, and they all demonstrate that the common shapes of microbial survival curves do not contain enough information to infer whether the targeted microbial population is genetically or physiologically uniform or a mixture of subpopulations. The presented analysis lends support to the notion that any proposed microbial survival kinetic model’s validity should be tested by its ability to predict survival patterns not used in its formulation and not by statistical fit criteria.</p></div>","PeriodicalId":565,"journal":{"name":"Food Engineering Reviews","volume":"16 2","pages":"163 - 178"},"PeriodicalIF":5.3,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140054385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the freeze thawing cycle can cause various chemical and physical damages to food, which are the main influencing mechanisms of low-temperature preservation. The size of ice crystals determines the degree of physical damage to cells, which has a significant impact on the freezing quality. Magnetic field (MF) treatment is a physical method that has been found to be milder, more effective, and have no obvious side effects compared to chemical treatments. Numerous studies have reported that MF promotes the cold storage of food, prolongs shelf life, inhibits ice crystal nucleation, increases supercooling, accelerates freezing speed, and reduces ice crystal sizes significantly. However, the role of MF in ice nuclei formation is still unresolved, and there are inconsistencies in research results and a lack of clear understanding of its potential mechanism. This paper aims to introduce the influence of MF on the formation and growth of ice crystals, summarize freezing curves on water and salt solutions, and analyze MF applications from two aspects: the thermodynamic mechanism and molecular dynamics point of view for freezing processes. Additionally, it discusses the problems encountered in recent researches and presents future development trends. The conclusion can be drawn that MF demonstrates great application potential in the field of freezing processes and food quality attribute evaluation. However, many questions remain with little consensus in the literature regarding their roles, and the mechanism of action is not unified. The application of MF in food freezing processes is still challenging. This paper hopes to provide guidance for future work on food freezing and contribute to the advancement of this field.</p></div>","PeriodicalId":565,"journal":{"name":"Food Engineering Reviews","volume":"16 3","pages":"396 - 421"},"PeriodicalIF":5.3,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140047639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The processing parameters that influence the most uniformity of the heating in OH are the electric field strength and the frequency. Therefore, recent trends have focused on studying the application of frequencies in the order of kHz and electric fields higher than 100 V/cm. In this regard, and considering only the applied field strength in a way to easily differentiate them, three ohmic systems could be distinguished: OH (&lt; 100 V/cm), moderated electric fields (MEF) (100–1000 V/cm), and ohmic-pulsed electric fields (ohmic-PEF) (&gt; 1000 V/cm). The advantages of applying higher electric fields (MEF and ohmic-PEF) over OH are, on the one hand, their much higher heating rate and, on the other hand, their capability to electroporate cells, causing the release of intracellular ionic compounds, and therefore, uniformizing the electrical conductivity of the product. This strategy is especially interesting for large solid foods where conventional heating applications lead to large temperature gradients and quality losses due to surface overtreatment. Therefore, the aim of this work is to review the state of the art of OH technologies, focusing on MEF and ohmic-PEF. The advantages and disadvantages of MEF and ohmic-PEF compared to OH and their potential for improving processes in the food industry are also discussed.</p></div>","PeriodicalId":565,"journal":{"name":"Food Engineering Reviews","volume":"16 2","pages":"225 - 251"},"PeriodicalIF":5.3,"publicationDate":"2024-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12393-024-09368-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139945418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Examples of the first kind are the original and modified versions of the logistic (Verhulst) equation and of the second the dynamic Weibull survival or Gompertz growth models. In the first-order inactivation kinetics, the isothermal logarithmic survival rate is a function of temperature only. Therefore, converting its static algebraic form into a dynamic differential rate equation, or vice versa, is straightforward. There is also no issue where both the static and dynamic versions of the survival or growth model are already in the form of a differential rate equation as in the logistic equation of growth. In contrast, converting the nonlinear static algebraic Weibull survival model or the Gompertz growth model into a dynamic differential rate equation, requires replacement of the nominal time <i>t</i> by <i>t</i>*, defined as the time which corresponds to the momentary static survival or growth ratio at the momentary temperature. This replacement of the nominal time in the rate equation with a term that contains the momentary survival or growth ratio eliminates inevitable inconsistencies and renders the resulting dynamic model truly predictive.
