Determinação da concentração de beta-glucano em cogumelo Agaricus blazei Murill por método enzimático

Abstract: Ciênc. Tecnol. Aliment., Campinas, 23(3): 312-316, set. -dez. 2003Determinação da concentração de β-glucano em cogumelo Agaricus blazei Murill por método enzimático, Park et al. -INTRODUÇÃOA maioria dos cereais contém quantidades variáveis de β−(1→3) e β−(1→4)-D-glucanos. Esses polissacarídeos são comuns entre os cereais e ocorrem em grande quantidade no endosperma e na parede celular de cevada, trigo e aveia [2,11]. A importância metabólica do β−glucano na saúde e na nutrição humana foi recentemente revisada … Show more

“…Its methanolic and ethanolic extracts presenting the highest total phenolics content (41.72 and 37.93 mg GAE per g extract) revealed the lowest EC 50 Tables 4 and 5, respectively. Regarding the antibacterial action, ethanolic extracts were more effective than methanolic ones.…”

“…For cultivated mushrooms, the type and amount of compost and fertilizer used can also have influence in the results (Park, Ikegaki, Alencar, & Aguiar, 2003). Differences found in individual compounds can also be attributed to the diversity of extraction, derivatization or even quantification methods employed (Ribeiro, Pinho, Andrade, Baptista, & Valentão, 2009).…”

“…No quantitative enzymatic procedure has been described for the measurement of β-glucan in mushroom fruiting bodies or mycelium. Park et al (19) measured the β-glucan content of Agaricus blazei by first extracting the nonstarch polysaccharide fraction according to the dietary fiber method of Prosky et al (20,21) using thermostable α-amylase and amyloglucosidase to hydrolyze starch/glycogen in the mushroom sample and recovering nonstarch polysaccharide by alcohol precipitation, washing, and drying. The recovered polysaccharide was subsequently acid hydrolyzed, and glucose was determined enzymatically.…”
