The taste of fresh mushrooms is always appealing. Phlebopus portentosus the only porcini that can be cultivated artificially in world, with a daily output up to 2 tons and large sales market. Fresh are very susceptible microbial attacks when stored at 0–2 °C for more than 5 days. Therefore, freshness P. must evaluated during its refrigeration ensure food safety. According their freshness, samples were divided into three categories, namely, category I (1–2 days, 0–48 h, recommended...

Origin traceability is an important step to control the nutritional and pharmacological quality of food products. Boletus edulis mushroom a well-known resource in world. Its medicinal properties are drastically varied depending on geographical origins. In this study, three sensor systems (inductively coupled plasma atomic emission spectrophotometer (ICP-AES), ultraviolet-visible (UV-Vis) Fourier transform mid-infrared spectroscopy (FT-MIR)) were applied for origin 184 samples (caps stipes)...

Boletes are recognized as a worldwide delicacy. Adulteration of the expired and low-value sliced boletes is pressing problem in supply chain commercial boletes. This study aimed at developing rapid method to identify storage duration species boletes, using near-infrared (NIR) spectroscopy. In study, 1376 fruiting bodies wild-grown were collected from 2017 2020 Yunnan, containing four common edible A NIR spectroscopy-based strategy was proposed, that is, ensure they within shelf life firstly;...

This study presents an alternative data fusion strategy for the discrimination of multi-source porcini mushrooms based on mathematical algorithms.

Nowadays, Wolfiporia extensa as a popular raw material in food and medicine industry has received increasing interests. Due to supply shortage, this species of edible medicinal mushroom been cultivated some provinces China. In the present study, W. collected from six regions Yunnan Province China were analyzed by an integrated method based on Fourier transform infrared (FT-IR) spectroscopy ultra-fast liquid chromatography (UFLC) coupled with multivariate analysis including partial least...

This study aimed to determine the contents of main mineral elements wild Boletus edulis and assess its edible safety, which may provide scientific evidence for utilization this species. Fourteen (Ba, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Na, Ni, Sr, V Zn) in caps stipes B. as well corresponding surface soils collected from nine different geographic regions Yunnan Province, southwest China were determined. The analyses performed using inductively coupled plasma atomic emission spectrometer...

Different species and geographic regions of mushrooms differ in nutritional medicinal value, while traditional chemical methods are destructive, time-consuming expensive to sample. In contrast, infrared spectroscopy enables accurate, noninvasive, rapid inexpensive identification quality analysis. But technology has produced a large number data, common data analysis cannot be analyzed, chemometrics can solve this problem. recent years, the combination made some progress qualitative...

Boletes are favored by consumers because of their delicious taste and high nutritional value. However, as the storage period increases, fruiting bodies will grow microorganisms produce substances harmful to human body. Therefore, we need identify boletes ensure quality. In this article, two-dimensional correlation spectroscopy (2DCOS) images directly used for deep learning modeling, complex spectral data analysis process is transformed into a simple digital image processing problem. We...

Leccinum rugosiceps is an edible mushroom belonging to genus of Boletaceae. Its fruiting bodies are richer in nutrients than many vegetables and fruit. The model support vector machine was established for the discrimination L. from regions based on rapid low-cost ultraviolet infrared spectroscopies. mid-level data fusion performed by machine. Compared a single spectroscopic technique, provided higher accuracy selecting most significant variance matrixes partial least squares discriminant...

Geographical traceability is important to consumer protection and quality control of edible mushrooms. In this work, Fourier transform infrared (FT-IR) spectroscopy, ultraviolet (UV) inductively coupled plasma-atomic emission spectrometry were used for 312 mushroom samples from eight different geographical origins in combination with multivariate statistical analysis. Initially, FT-IR, UV spectra, 14 elements obtained 8 analyzed, respectively. Meanwhile, the principal components three...

In this study, the individual and data fusion of Fourier transform infrared (FT-IR) spectroscopy inductively coupled plasma atomic emission spectrometry (ICP–AES) were used for discrimination five species Boletaceae mushrooms with aid support vector machine (SVM). First, original FT-IR spectra 230 samples different preprocessed optimized by second derivative (2D), Savitzky–Golay filter (15:1) standardized normal variate. Second, datasets ICP–AES integrated, low-level strategy was to classify...

Nowadays, wild-grown edible mushrooms which are natural, nutritious, and healthy get more popular by large consumers. In this paper, UV spectra of different Boletaceae with the aid partial least squares discriminant analysis (PLS-DA) hierarchical cluster (HCA) were shown to be a practical rapid method for discrimination purpose. The specimens Boletus edulis , ferrugineus tomentipes Leccinum rugosiceps, Xerocomus sp. described based on spectra. From results, all characterized strong...

Discrimination of wild and cultivated mushrooms is important for their quality assessment. In this study, data fusion infrared ultraviolet spectroscopies combined with support vector machine or random forest were applied the discrimination W. cocos P. portentosusis. For low- mid-level classification models, accuracies validation set are 90.91% 98.70%, respectively. However, parameter c too large which means models unreliable. high-level fusion, results showed that accuracy 100% sensitivity...

Abstract The objective of this study is to better quantify the occurrence, intake, and potential risk from Hg in fungi traditionally foraged SW China. concentrations intakes were measured 42 species including a “hard” flesh type polypore a” soft” edible that are used traditional herbal medicine, collected during period 2011–2017.
