If a color irreversible intensification or fading can be represented by a single colorimetric measure, such as Hue or vector in a color space, and if this transformation temperature-dependent kinetics and its parameters are also known, then a scanned and transmitted tag’s color coordinates at any time can be used to construct a single equivalent constant-temperature history and an infinite number of equivalent varying-temperature histories that would have produced the same colorimetric reading. A way to test such temperature histories equivalency is to have, at least initially, <i>two different colors</i> following two different transformation kinetics, and use one to predict, or at least approximate, the other’s reading. This is demonstrated with simulated colorimetric changes that follow zero-order kinetics, representing fixed order intensification, and Weibull (stretched exponential) intensification and fading, representing nonlinear kinetics. Both were tested by predicting readings <i>not used</i> in their equivalent temperature history construction. The simulations indicate that the traditional notion of a meaningful constant temperature equivalent existence might need reconsideration, especially for nonlinear color transformation kinetics. It is proposed to try low-degree polynomials as equivalent temperature profile model equations first, replaced by elaborate algebraic expressions or stochastic models if needed. Also demonstrated is how successive colorimetric readings from the same lot can be used to construct its almost-true external temperature history as judged by fit criteria.</p></div>","PeriodicalId":565,"journal":{"name":"Food Engineering Reviews","volume":"16 3","pages":"356 - 370"},"PeriodicalIF":5.3,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140802306","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}

Therefore, decontaminating food is vital before marketing and circulation. Radio frequency (RF) heating stands out in several branches of industry, mainly food processing, as an alternative method to conventional pasteurization which takes long process times and overheating. RF heating functions without relying on heat conduction. It generates internal heat by inducing the rotation of polar molecules and the motion of ions. The advantages of dielectric heating with greater wave penetration include rapid, uniform and volumetric heating, presenting high energy efficiency. Furthermore, it is an effective, validated method for eliminating pathogens in agricultural products and is free from chemical residues. Although many reviews have discussed this technology, few reviews have covered the research trends in this field in the recent years, during which the number of studies discussing RF treatment of foods have increased. Therefore, this review focuses on the RF applications in the food industry for pest control, microbial and enzymatic inactivation of solid, liquid, and powdered foods in the last five years.

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.

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}

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 (< 100 V/cm), moderated electric fields (MEF) (100–1000 V/cm), and ohmic-pulsed electric fields (ohmic-PEF) (> 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.

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.
