“…Edible fungi (mushrooms) have a large fruiting body, taste delicious, and have high edible, medicinal, and economic values (Sun et al 2019;Xue et al 2019). Edible fungi are a healthy food with significant therapeutic effects and are rich in bioactive compounds, including polysaccharides (e.g., αand β-glucan), proteins, peptides, polyphenols, terpenoids, vitamins, and dietary fiber (Khan & Tania, 2012;Reis et al 2012;Yan et al 2018).…”

Edible fungi are rich in nutrition, but they are susceptible to spoilage, and often prolonged by drying. RF and microwave energy drying have the advantages of short drying time, high energy efficiency and good process control. However, to develop an effective dielectric drying method, it is important to understand dielectric properties, the major factor characterizing the interaction between the electromagnetic energy and the food. At present, there is a lack of research on dielectric properties of edible fungi. In this study, a vector network analyzer and an open-ended coaxial-line probe were employed to measure the dielectric parameters. The dielectric parameters were observed at different temperatures (25–85 °C) for edible fungi powder with moisture content ranging from 5 to 30% wet basis over a frequency range of 1–3000 MHz. The relationship between the dielectric properties and frequency, temperature, and moisture content were obtained via regression analysis. Further, the dielectric penetration depth was calculated, and the effects of frequency, moisture content, and temperature on the penetration depth were also analyzed. The results showed that the dielectric properties of edible fungi powder increased with an increase in moisture content and temperature, while they decreased with increasing frequency. At high moisture content and temperature, the increase in dielectric properties was slightly larger than that at low moisture content and temperature. The dielectric properties changed more evidently at lower radio frequencies than at higher radio frequencies. The penetration depth decreased with an increase in temperature, moisture content, and frequency. It can be concluded that a large penetration depth at radio frequencies below 100 MHz could be used to dry edible fungi on a large scale, whereas microwave energy could be employed for drying edible fungi on a small scale.

In this work, a new quantitative analysis method of multi-components analysis via a single marker strategy coupled with high-performance liquid chromatography (HPLC) analysis, was proposed to analyze nine nucleosides (cytidine, uridine, 2′-deoxyuridine, inosine, guanosine, 2′-deoxyguanosine, thymidine, adenosine, and 2′-deoxyadenosine) as quality control markers in Rhizoma Paridis. Guanosine was set as the internal reference substance, whose content in Rhizoma Paridis was determined using conventional external standard method. Then, relative correction factors between guanosine and the other eight nucleosides were measured respectively. The amounts of the other eight components were calculated according to the relative correction factors by the quantitative analysis of multi-components via a single marker method. Finally, the result of vector angle cosine analysis showed that there was no significant difference of the contents between the external standard method and the quantitative analysis of multi-components via a single marker method, indicating that the quantitative analysis of multi-components via a single marker method can be applied for the quality control of Rhizoma Paridis. As far as we know, this is also the first report to analyze nucleosides by the quantitative analysis of multi-components via a single marker method, providing an efficient and promising quality assessment method for other traditional Chinese medicine containing nucleosides.

The fuzzy control model took et s as input, and then the temperature of compost was indirectly controlled until the actual temperature reached the expected effect.…”

“…The temperature decreased rapidly to improve the working efficiency; when the actual value was close to the preset value, the temperature regulating equipment operated with low power to avoid overshoot. Therefore, the decrease of ambient temperature was fast first and slow then, and the temperature change tended to be stable when it dropped to about 17°C , which was the preset value of environment temperature, which was obtained by the system's independent decision-making by Equation (1). When the temperature difference was large, the temperature of the compost decreased a little faster; Finally, the compost temperature was stable in the allowable error range, and the response speed v was about 0.56°C/ h.…”

Environment parameters are the main factors affecting the growth and development of Agaricus bisporus. Because of the requirements of environmental conditions for high-efficiency industrialized production of Agaricus bisporus, equipments for environment control were developed. Based on the variable operating equipment, a multi-factor fuzzy controller was designed to realize the comprehensive control of ambient temperature, humidity, CO 2 concentration, and the temperature and moisture of the compost. The test results showed that the temperature control error was less than ±0.5°C and the response speed was more than 0.5°C/h; The control error of ambient humidity was less than ±2% RH, and the response speed was more than 9% RH per hour; The moistures at different points in compost ranged from 50% to 70% with a standard deviation of 4.04. The control accuracy of environmental CO 2 concentration was within 200 µmol/mol. The overall performance of the control system was stable and reliable, which could meet the requirements of environment factors for the growth of Agaricus bisporus. The system can provide technical support and reference for the automatic and precise control of the environment during the industrialized production of Agaricus bisporus.
