Color has great importance in agriculture due to its relationship with plant pigments and therefore, development biochemical changes. Due the trichromatic vision, instruments equipped CCD or CMOS sensor represent color mixture of red, green blue signals. These values are often transformed into HSL (hue, saturation, luminance) space. Beyond average visible surface area, histograms can distribution. Interpretation distribution be challenging information shared among histograms. Hue spectra...
Abstract Application of cold storage temperatures below optimum induces a high risk and threat chilling injury (CI) in the case sensitive commodities. Sweet pepper belongs to this group vegetables, so our main objective was investigate monitor effect non-optimal (2.5 5 °C) induced stress (chilling injury) on kápia type sweet ( Capsicum annuum L. ) during its postharvest by nondestructive quality measuring methods. Fresh, semi-matured (reddish-green colored) samples ‘Kapitány F 1 ’ cultivar...
In this study, liquid egg, albumen, and egg yolk were artificially inoculated with E. coli. Ultrasound equipment (20/40 kHz, 180/300 W; 30/45/60 min) a circulation cooling system was used to lower the colony forming units (CFU) of coli samples. Frequency, absorbed power, energy dose, duration sonication showed significant impact on 0.5 log CFU/mL in 0.7 decrease at 40 kHz 6.9 W power level. Significant linear correlation (p < 0.001) observed between dose The results that can be useful...
Abstract The aim of this study was to determine the effect ultrasound treatment on foaming properties egg white. samples were sonicated at 20/40 kHz and 180/300 W equipment power (3.7/6.9 absorbed power) for 30, 45 60 minutes. Foam capacity had been increased by 25% due sonication 40 6.9 This phenomenon may be caused homogenization protein exposure hydrophobic groups that improve adsorption onto air/water interfacial molecules. It is found frequency duration have no significant impact...
In this study, sonication with mild heat treatment was used to reduce the
The aim of the study was to select most suitable freezing and thawing method for preserving quality pasta flata type Parenica cheese comparing different methods: slow, shock (circulated air) cryogenic at room temperature in a refrigerator, respectively. To observe effects these methods on some properties weight, pH, dry-matter content were measured, stringiness examined, compression test performed texture analysis. Thermophysical determined by DSC: unfreezable water content, onset point...
In the case of organic production quality assessment fruits and vegetables is especially important. Monitoring maturation ripening process, early detection diseases, decision about harvest date postharvest treatment need reliable, objective – preferably non-destructive testing methods. Dynamic hardness or stiffness measurement methods (resonance, impact, wave propagation) offer very useful tools in this field, but with strong limitations applicability area and/or physical interpretation...
The aim of our work was the non-invasive maturity determination Golden Delicious apples during 35 days long cold (2°C) and shelf-life storage (20°C).Significant difference found between at 20°C stored samples in case mass loss, acoustic stiffness coefficient, RGB color parameters chlorophyll content related (IAD, F0, FM, FV/FM).The DA-value fluorescence values did not show significant differences blushed shaded sides samples.All applied measuring methods were to be suitable for detection...
Abstract In the experiments, sound generated during breaking of chocolate samples was examined. The fracture performed by a precision penetrometer, recorded. Texture index (TI) calculated from resulting signal. First change TI monitored as function samples' temperature. sample groups same dark with different temperatures were completely separated each other statistical tool (LDA, linear discriminant analyses), but no trend found to describe change. Secondly, based on TI, we could identify...
