Comparison of free amino acid, carbohydrates concentrations in Korean edible and medicinal mushrooms

Chemical composition and antioxidant activity of dried powder formulations of Agaricus blazei and Lentinus edodes

“…The amounts of mannitol and trehalose in APF were higher than the values reported by Tsai et al (2008) in A. blazei fruiting bodies from Taiwan (7.94 g/100 g and 2.98 g/100 g dw, respectively). Kim et al (2009) described the presence of trehalose in L. edodes from Korea, not as a free sugar but obtained after polysaccharides hydrolysis. The sugar amounts found in LPF were lower than the levels found in L. edodes fruiting bodies from Portugal (69.65 g/100 g dw; Reis et al, 2012a).…”

“…Lentinus edodes, known as shiitake mushroom, has received great attention due to positive health effects including antitumour and hypocholesterolemic activities (Kitzberger, Jr, Pedrosa, & Ferreira, 2007), related to the presence of β-glucans (Minato, Mizuno, Terai, & Tsuchida, 1999). There are available in the literature different studies on the nutrient and phytochemical composition of Agaricus blazei and Lentinus edodes fruiting bodies (e.g., Andrade, Minhoni, & Zied, 2008;Çaglarirmak, 2007;Carvajal et al, 2012;Cheung, Cheung, & Ooi, 2003;Cheung & Cheung, 2005;Choi, Lee, Chun, Lee, & Lee, 2006;Firenzuoli et al, 2007;Kim et al, 2009;Kitzberger et al, 2007;Longvah & Deosthale, 1998;Manzi, Gambelli, Marconi, Vivanti, & Pizzoferrato, 1999;Mattila et al, 2001;Oliveira et al, 2007;Reis et al 2012a and b;Soares et al, 2009;Tsai et al, 2007;Yang et al, 2002). Nevertheless, as far as we know, this is the first report on chemical composition (nutrients and bioactive compounds) and antioxidant activity (free radical scavenging activity, reducing power and lipid peroxidation inhibition) of dried powder formulations of the mentioned mushroom species.…”

The Status of Edible Mushrooms Resource Development and Nutrition Evaluation in Sichuan Province, China

“…The edible mushrooms' yield under 60,000 tons in 1978, but had increase to 25,717,000 tons in 2011, and the production value more than 150 billion. We earn foreign exchange through export reach $2.4 billion, becoming the largest edible mushrooms producing country and exporter in the world [1][2][3].…”

“…Since the 60 s and 70 s of the 20th century, Sichuan province have a large-scale cultivation of edible mushrooms, and then the varieties of them like Tremella fuciformis, Plearotus ostreatus, flammulina velutipes, et al gradually spread. The edible mushrooms' yield in Sichuan increase 408,800 tons in 2002 to 1,005,000 in 2007, and the production value more than 5 billion yuan in 2010 (ranked 3 rd in the country) [3][4][5][6]. The distribution of the edible mushrooms resources can mainly divided into the following five: 1) Dayi, Mianzhu, Emei Mountain, Pengxi, Hongya, Xuanhan, et al are the mushrooms-producing core areas; 2) Jintang, Zhongjiang, Shifang, Pixian, Jianyang, Dujiangyan, Qingbaijiang, et al are the core areas of succeeded cultivation; 3) the core areas of anti-season mushrooms production are Hongyuan, Maerkang, Aba, et al ; 4) Tongjiang, Nanjiang, Pingwu, Wanyuan, et al are the traditional products of the mushrooms' core areas; 5) the rare wild mushroomsproducing core areas are Xichang, Daocheng, Xiangcheng, et al Among them, the yield of edible mushrooms in Dayi, Jintang, Shifang, et al is accounted for over 25% of the local agricultural production, becoming a mainstay of the local agricultural industry.…”

Effect of addition amino acids on the mycelial growth and the contents of β-glucan and γ-aminobutyric acid (GABA) in Sparassis latifolia

“…균사체와 자실체의 GABA 함량을 확인한 연 구에서 균사체의 GABA 함량을 확인한 결과 Hypsizigus marmoreus (white) 125 mg/100 g, Agrocybe cylindracea 123 mg/100 g이었으며, Cordyceps militaris (strain cm5) 과 Ganoderma lucidum은 각각 69 mg/100 g, 7 mg/100 g으로 본 연구의 PDBG 1.4% 배지에서의 GABA 함유량 은 H. marmoreus와 A. cylindracea보다는 낮고 C. militaris (strain cm5)과 G. lucidum 보다는 높은 결과를 보였다 (Chen et al, 2012). 국내 버섯의 GABA 함유량을 확인한 연구에서는 식용 버섯 중 Agaricus bisporus는 79 mg/ 100 g, Lentinus edodes는 27 mg/100 g으로 본 연구 결과는 국내 버섯보다 GABA 함량이 높은 것으로 확인되 었다 (Kim et al, 2009) …”
