“…K values increased progressively (p < 0.05) over time for different treated samples because of the degradation of ATP to derivative compounds [1]. Generally, a K value of 60% fish muscle was taken as the highest acceptable level; as proposed by the European Commission [19]. Briefly, the K value of CK1 reached 62% at day 12, while the CK2, C1, and C2 group exceeded this limitation at day 16, 20, and 24, respectively.…”

Featured Application: The monitoring of quality characteristics of Half-smooth tongue sole (HTS, Cynoglossus semilaevis Günther) is essential during refrigerated period based on the edible coating incorporated with MAP treatment, which has not displayed in the previous literatures. Meanwhile, the low-field nuclear magnetic resonance (LF-NMR) and magnetic resonance imaging (MRI) technology has a potential development to assess the quality of aquatic products, which is applied to assess the water distribution and migration of HTS fillets during 24-day storage. This study demonstrate that results of LF-NMR and MRI have the close connection with the physicochemical parameter of HTS fillets and can be applied to monitor water migration in a noninvasive and fast way.Abstract: Nondestructive and fast measurement and characterization of fish is highly desired during various processing treatments. This research investigated the effectiveness of low field LF-NMR and MRI as fast monitoring techniques to estimate the qualities of half-smooth tongue sole fillets treated with edible coating combined with modified atmosphere packaging during refrigeration. T 2 relaxation spectra showed three peaks representing bound water (T 21 ), immobile water (T 22 ), and free water (T 23 ), respectively. pT 22 accounted for the largest proportion of three types of water, followed by pT 23 . The weighted MRI provided the internal structure information associated with different samples, indicting the combination of edible coating and MAP (70% CO 2 + 30% N 2 ) is the best performance in the maintenance of qualities and freshness of HTS fillets. All results demonstrated that the combination of LF-NMR and MRI as fast and nondestructive methods have great potential to monitor qualities deterioration and predict shelf life in of HTS fillets during refrigerated storage.

“…Performance of the calibration and prediction models were evaluated using several statistical parameters, including coefficient of correlation (r) between measured and predicted value [10], root mean square error of calibration (RMSEC), root mean square error of prediction (RMSEP) and number of latent variables [23]. A good calibration model should have a high correlation coefficient (rcal) and a low RMSEC.…”

“…The average spectra were processed independently using different preprocessing methods including moving weighted average smoothing, normalization, S-G first-and second-order derivative, multiplicative scatter correction (MSC), and standard normal variate (SNV) in order to remove any irrelevant information such as high-frequency random noise, baseline drift, signal-to-background ratio, and others [23]. The averaging technique is used to reduce the number of wavelengths or to smooth the spectrum of tomatoes.…”

Abstract:The objective of this study was to develop a nondestructive method to evaluate chemical components such as moisture content (MC), pH, and soluble solid content (SSC) in intact tomatoes by using hyperspectral imaging in the range of 1000-1550 nm. The mean spectra of the 95 matured tomato samples were extracted from the hyperspectral images, and multivariate calibration models were built by using partial least squares (PLS) regression with different preprocessing spectra. The results showed that the regression model developed by PLS regression based on Savitzky-Golay (S-G) first-derivative preprocessed spectra resulted in better performance for MC, pH, and the smoothing preprocessed spectra-based model resulted in better performance for SSC in intact tomatoes compared to models developed by other preprocessing methods, with correlation coefficients (r pred ) of 0.81, 0.69, and 0.74 with root mean square error of prediction (RMSEP) of 0.63%, 0.06, and 0.33% Brix respectively. The full wavelengths were used to create chemical images by applying regression coefficients resulting from the best PLS regression model. These results obtained from this study clearly revealed that hyperspectral imaging, together with suitable analysis model, is a promising technology for the nondestructive prediction of chemical components in intact tomatoes.

“…An RPD between 1.5 and 2 indicates that the calibration model can distinguish between low and high values of the response variable; a value between 2 and 2.5 means that quantitative predictions are possible, and an RPD value between 2.5 and 3.0 indicates an excellent prediction performance. On the other hand, a RER value of 10 or higher indicates excellent performance of the model in actual application 20,21 .…”

eggshells play a number of important roles in the avian and reptile kingdom: protection of internal contents and as a major source of minerals for developing embryos. However, when researching these respective roles, eggshell thickness measurement remains a bottleneck due to the lack of a non-destructive measurement techniques. As a result, many avian and reptile research protocols omit consideration of eggshell thickness bias on egg or embryo growth and development. Here, we validate a non-destructive method to estimate eggshell thickness based on terahertz (THz) reflectance spectroscopy using chicken white coloured eggs. Since terahertz waves are reflected from outer aireggshell interface, as well as the inner eggshell-membrane boundary, the resulting interference signals depend on eggshell thickness. Thus, it is possible to estimate shell thickness from the oscillation distance in frequency-domain. A linear regression-based prediction model for non-destructive eggshell thickness measurement was developed, which had a coefficient of determination (R 2) of 0.93, RMSEP of 0.009, RPD of 3.45 and RER 13.67. This model can estimate eggshell thickness to a resolution of less than 10 μm. This method has the potential to expand the protocols in the field of avian and reptile research, as well as be applied to industrial grading of eggs.
