Human Olfaction

This work aims to advance understanding of the differentiation of mushroom species through electronic devices that use sensors of various technologies and techniques for pattern recognition, comparing mainly volatile substances that emanate from them. In this first phase, the capacity of human olfaction to differentiate between the smell released by different wild mushrooms of the genus Amanita was analyzed by means of a triangular sensory test, comparing later the data to those obtained for the same samples with an electronic nose in a similar test. The results, still very preliminary, encourage imagining the wide application that these techniques will have and the feedback that this application can suppose for the training of the sense of human olfaction.

Due to its high sensitivity, low price and fast response speed, gas sensors based on metal oxide nanomate-rials have attracted many researchers to modify and explore the materials. First, pure indium oxide (In2O3) nanotubes (NTs)/porous NTs (PNTs) and Ho doped In2O3 NTs/PNTs are prepared by electrospinning and calcination. Then, based on the prepared nanomaterials, the 6-channel sensor array is obtained and used in the electronic nose sensing system for wine product identification. The system obtains the frequency signals of different liquor products by means of 6-channel sensor array, analyzes the extracted electronic signal characteristic information by means of ordinary least squares, and introduces the pattern recognition method of moving average and linear discriminant to identify liquor products. In the experiment, compared with pure In2O3 NTs sensor, pure In2O3 PNTs sensor has higher sensitivity to 100 ppm ethanol gas, and the sensitivity is further improved after mixing Ho. Among them, 6 mol% Ho + In2O3 PNTs have the highest sensitivity and the shortest response time; based on the electronic nose system composed of prepared nanomaterial sensor array, frequency signals of different Wu Liang Ye wines are collected. With the extension of acquisition time, the corresponding frequency first decreases and then becomes stable; the extracted liquor characteristic signal is projected into two-dimensional space and three-dimensional space. The results show that the pattern recognition system based on this method can extract the characteristic signals of liquor products and distinguish them.

Microbiological assessment, sensory evaluation, and electronic nose (AromaScan) analysis were performed on yellowfin tuna stored at 0, 4, 10, and 22°C for 0, 1, 3, 5, and 9 days. Fish color, texture, appearance, and odor were evaluated by a trained sensory panel, while aroma-odor properties were evaluated using an AromaScan. Bacterial enumeration was performed using plate count agar containing 1.5% NaCl. Tuna fillets stored at 22°C for 3 days or longer had a bacterial load of over 107 CFU/g and were rated not acceptable for consumption (grade C) by the sensory panel. Tuna fillets stored at 4°C for 9 days or 10°C for over 5 days were rated as grade C products and also had a bacterial load of over 107 CFU/g. The change in fish quality as determined by AromaScan followed increases in microbiological counts in tuna fillets, indicating that bacterial load can serve as a useful and objective indicator of gross spoilage. Electronic nose devices can be used in conjunction with microbial counts and sensory panels to evaluate the degree of decomposition in tuna during storage.

Objective: To identify edible mushroom species with medicinal uses in Estado de México.Design/Methodology/Approach: Based on the bibliographic review of local ethnomycological inventories, weeklymarket visits, semi-structured interviews with vendors, and the collection and taxonomic identification of mushrooms, information was gained regarding medicinal mushroom nomenclature, local knowledge and cultural importance.Results: A list of 36 edible mushroom species was compiled, which can be divided into 11 categories of use, mainly in treating digestive and circulatory illnesses.Study Limitations/Implications: This is a descriptive and exploratory study of edible mushrooms with medicinal uses, and therefore it is necessary to include more empirical and scientific evidence from other similar cases.Findings/Conclusions: There is limited knowledge on medicinal fungi species, implying that they are underexploited asa resource among local inhabitants. Lycoperdon perlatum and Lactarius indigo were cited as having the highest quantityof medicinal uses.

Abstract: The tropical region, which has the highest macrofungi diversity, has not been fully exploited instead of this is an important component of the global diversity. However, no work has been carried out to assess such diversity in Tripura. Since tropical forests are diverse in plant composition and structure, hence the objective of this study was to explore the mushroom species richness in Tripura, Northeast India with the aim of producing a checklist along with their present geographical distributions, key identification characters and valid photographs. Field surveys and collection of mushrooms were carried out in Tripura covering different sites during 2015–2018. Data on macrofungal diversity, distribution patterns and taxonomic identification were analyzed. A total of 217 wild mushrooms were documented from eight districts of Tripura, northeastern India. Out of 217 samples, 202 samples were identified up to the genus level, 125 samples were identified up to the species level.  A total of 76 genera belonging to 60 families and 25 orders were classified in this ecological study. The majority of macrofungi belong to the family Polyporaceae (30 nos), and order Agaricales (103 specimens). The wild macrofungi were collected from 56 sites of eight districts of this state and the maximum macrofungi diversity was recorded from Sepahijala District. Present findings also observed that the maximum wild fungi of this state grow on different plant parts. This is the preliminary study on documentation of wild macrofungi from eight districts of Tripura, northeastern India and it will be used as a reference database of wild mushrooms of this state, which will also help in future research work in different fields.
