“…The quantities of the main TM components including total sugar, reducing sugar, protein, total ash, crude fat, crude fiber, and total polyphenols were measured using the phenol-sulfuric acid method [ 19 ], direct titration [ 20 ], the Kjeldahl method [ 21 ], combustion [ 22 ], Soxhlet extraction [ 23 ], double differences method [ 24 ], and the Folin-Ciocalteu method [ 25 ], respectively. The quantities of triterpenoids, mannitol, and vitamins were measured using high-performance liquid chromatography (HPLC) [ 26 – 28 ].…”

Tuber melanosporum (TM), a valuable edible fungus, contains 19 types of fatty acid, 17 types of amino acid, 6 vitamins, and 7 minerals. The antidiabetic and antinephritic effects of TM and the underlying mechanisms related to oxidative stress were investigated in db/db mice. Eight-week oral administration of metformin (Met) at 0.1 g/kg and TM at doses of 0.2 and 0.4 g/kg decreased body weight, plasma glucose, serum levels of glycated hemoglobin, triglyceride, and total cholesterol and increased serum levels of high-density lipoprotein cholesterol in the mice, suggesting hypoglycemic and hypolipidemic effects. TM promoted glucose metabolism by increasing the levels of pyruvate kinase and hepatic glycogen. It also regulated the levels of inflammatory factors and oxidative enzymes in serum and/or the kidneys of the mice. Additionally, TM increased the expression of nuclear respiratory factor 2 (Nrf2), catalase, heme oxygenase 1, heme oxygenase 2, and manganese superoxide dismutase 2 and decreased the expression of protein kinase C alpha, phosphor-janus kinase 2, phosphor-signal transducer and activator of transcription 3, and phosphor-nuclear factor-κB in the kidneys. The results of this study reveal the antidiabetic and antidiabetic nephritic properties of TM via modulating oxidative stress and inflammation-related cytokines through improving the Nrf2 signaling pathway.

“…Another study revealed that EBI may change the amylose content in rice because irradiation destroys the double helix structure of amylose, thereby reducing the amylose content [26]. Xue et al found that under the influence of a high-power electron beam, starch particles were decomposed, and the amylose structure was destroyed [16]. Nemtanu et al explored the degradation laws of solid amylose under accelerated EBI at the dose range of 10−50 kGy.…”

“…Xue et al studied the influences of 0−5.40 kGy EBI treatment on the gelatinization and the physical and chemical properties of corn flour. They found that the total content of starch and crude fibers in corn flour declined dramatically (p < 0.05), whereas the moisture and reducing sugar contents increased significantly (p < 0.05) [16]. Thus, EBI treatment can influence the physical and chemical properties of corn.…”

Electron beam irradiation (EBI) has high energy, no induced radioactivity, and strong degradation capacity toward mycotoxins, such as zearalenone (ZEN) and ochratoxin A (OTA). In this study, we determined EBI’s influence on the physical and chemical properties of corn contaminated with ZEN and OTA. Moreover, the toxicity of corn after EBI was assessed through a mouse experiment. Amylose content and starch crystallinity in corn decreased significantly (p < 0.05) at an irradiation dose higher than 20 kGy. Scanning electron microscopy results revealed that the starch particles of corn began to be crushed at 10 kGy. Essential and total amino acid contents in corn decreased significantly with increasing irradiation dose of EBI (p < 0.05). Feeding EBI-treated corn fodders to mice could significantly improve blood biochemical indexes. The EBI-treated group was not significantly different from the normal corn group and did not display histopathological changes of the liver. EBI treatment can influence the quality of corn to some extent and effectively lower the toxicity of ZEN and OTA in contaminated corn. The results provide a theoretical and practical basis for the processing of EBI-treated corn and its safety.

“…Morphologically rounded structures with varying sizes and smooth surfaces were observed. According to Xue et al (2017), the main component of the flour is starch, thus the polygonal or irregularly shaped granules observed in the microphotographs are starch granules. According to Otegbayo et al (2013), the variation in shape (polyhedral, oval and rounded) and size of the starch granules, is due to the drying treatment used and can be influenced by the amount of amylose and amylopectin.…”

The objective of this study was the production of flour from germinated jackfruit seeds. The seeds were germinated and dried at temperatures of 55, 65 and 75 °C under air drying speed of 1.0 and 1.3 m s-1. Afterward, the seeds were grounded in order to obtain the flour and characterized for chemical, physical and technological properties. It was observed that the germination increased the moisture content, proteins, and fibers; decreased the content of lipids, reducing sugars, tannins and phenolic compounds of the seeds. After dried, the flour moisture content decreased and the proteins and reducing sugars were concentrated. The flours showed good results for solubility, water, oil absorption capacity, and emulsifying properties. The moisture adsorption isotherms of the flours were classified as Type II and the GAB model was the best fit to the experimental data.
