This study used an odor sensing system with a 16-channel electrochemical sensor array to measure beef odors, aiming distinguish odors under different storage days and processing temperatures for quality monitoring. Six ranged from purchase (D0) eight (D8), three temperature conditions: no heat (RT), boiling (100 °C), frying (180 °C). Gas chromatography-mass spectrometry (GC-MS) analysis showed that odorants in the varied conditions. Compounds like acetoin 1-hexanol changed significantly...
We have developed a method to quantify the sweetness of negatively charged high-potency sweeteners coexisting with other taste substances. This kind sensor uses lipid polymer membranes as taste-sensing part. Two types outputs been defined in measurement sensor: one is relative value and CPA (the change membrane potential caused by adsorption) value. The shows good selectivity for sweeteners. On hand, several times higher than value, but influenced salty In order obtain both high sensitivity...
An odor sensing system with chemosensitive resistors was used to identify the gases generated from overheated cables prevent fire. Three different electric for a distribution cabinet were used. The had an insulation layer made of polyvinyl chloride (PVC) or cross-linked polyethylene (XLPE). heat resistance tested by differential thermal and thermogravimetric analyses. decomposition products investigated gas chromatography-mass spectrometry (GC-MS). For system, two types 16-channel array...
In this paper, we discuss and utilize the multiple-reflection attenuated total reflectance (ATR) method of near-infrared spectroscopy (NIRS) for determination glycogen content in Japanese wagyu beef.We have also conducted experiments on diffuse reflection to compare experimental results.Glycogen, as a reservoir glucose units, has positive effect palatability beef.The obtained nontreated spectra were preprocessed by several different methods, then calibration prediction model between spectral...
The deterioration or oxidation of the mineral oil in transformers poses risk short circuits. Convenient and effective methods are expected to be developed. Carbon-based sensor arrays were used this study identify quality variations for oil-filled by odors. sensitive layers odor-sensing system consisted different types GC stationary phase materials carbon black (CB) mixtures. We made a targeted selection utilizing polarities make array based on distinct components such as alkanes xylenes gas...
