Determining and applying ‘good’ postharvest quality control practices for otherwise highly sensitive fruits, such as sour cherry, is critical, they serve excellent media a wide variety of microbial contaminants. The objective this research was to report two series experiments on the modified atmosphere storage (MAP) cherries (Prunus cerasus L. var. Kántorjánosi, Újfehértói fürtös). Firstly, significant effect different washing pre-treatments various indices examined (i.e., headspace gas...

Tomato, and its concentrate are important food ingredients with outstanding gastronomic industrial importance due to their unique organoleptic, dietary, compositional properties. Various forms of adulteration often suspected in the different tomato-based products causing major economic sometimes even health problems for farmers, industry consumers. Near infrared (NIR) spectroscopy electronic tongue (e-tongue) have been lauded as advanced, high sensitivity techniques quality control. The aim...

Plums are one of the commercially important stone fruits that available on market in both fresh and processed form most sought-after products prunes, cans, jams, juices. Maturity, harvest, post-harvest technologies fundamentally determine relatively short shelf life plums which is often threatened by Monilinia spp. Causing brown rot worldwide. The aim present research was to use advanced analytical techniques, such as hand-held near infrared spectroscopy (NIRS) electronic tongue (e-tongue)...

This paper presents a Unified Grain Moisture Algorithm based on measurements of the real part complex permittivity grain at 149 MHz. The main goal method was to enable different moisture meter models provide equivalent predictions without calibration development. database that used create and test included 6189 samples representing 53 types US were collected over period 6 years. overall standard deviation differences with respect air-oven 0.34% moisture. Methods for transferring calibrations...

The quality of probiotics has been associated with bacteria and yeast strains’ contents their stability against conditioning factors. Near-infrared spectroscopy (NIRS), as a non-destructive, fast, real-time, cost-effective analytical technique, can provide some advantages over more traditional food control methods in evaluation. aim our study was to evaluate the applicability NIRS characterization viability prediction three commercial probiotic supplement powders containing lactic acid (LAB)...

The objective of our research was to evaluate the possible alteration organoleptic properties eggs produced by hens (Lohmann Brown-Classic) fed with diets containing different doses an industrial by-product enriched organic zinc (Zincoppyeast, ZP): Control 0%, ZP 2.5%, and 5.0%. Eggs were collected after 30 days (batch 1) 60 2) feeding experimental subjected chemical, microbiological, human sensory, e-nose, e-tongue analyses. There no significant difference among microbiological status three...

People have recently started to pay more attention the healthier lifestyle, which also includes consumption of natural and less processed food products. Honey as one most often used sweeteners has been reconsidered commonly used. However, honey target adulteration due its emerging use relatively high price. Therefore, there is an increasing need develop rapid evaluation methods for identification from different sources. Experiments performed with 79 authentic samples floral geographical...

Abstract One of the most important food safety issues is detection mycotoxins, ubiquitous, natural contaminants in cereals. Hyperspectral imaging (HSI) a new method science, it can be used to predict non-destructively changes composition and distribution compounds. That why, last decade, potential HSI has been evaluated many fields including mycotoxin research. The aim recent study was test feasibility for differentiation according toxin content cornmeal samples inoculated with Fusarium...

Dielectric-type instruments are the most widely used technology for grain moisture measurement. Measuring fundamental dielectric parameters (dielectric constant and loss factor) rather than instrument-specific is advantageous in terms of understanding physical basis measurement transferring calibrations; however, few meter models report such parameters. One reason this difficulty calibrating to measure High molecular weight alcohols commonly as reference materials research-type instruments....

Biofilm formation of four Listeria monocytogenes strains with different origin was compared as a function surface material (stainless steel, polystyrene and glass) conditioning. Hydrophobicity also examined. The number adhered cells in PBS broth determined for all during 144 h incubation at 30 °C epifluorescent microscopy. L. were similar biofilm forming abilities. slight differences could not been explained by hydrophobicity. Results showed that stainless steel provided the best formation....

Summary. Stone fruits play a significant role in fruit breeding, gastronomy, and industry, largely due to their beneficial nutritional composition. Ensuring the quality of these seasonal poses substantial challenge intensive customer demand. In this study, through example sour cherries, we demonstrate how variations can be effectively controlled at specific critical points along supply chain. Paired with various chemometric methods, near infrared spectroscopy reliably classified based on...
