Mineral essential elements for nutrition in different chocolate products
2016
In this work, the essential mineral nutritional elements in cocoa beans, in chocolates at different cocoa percentage (60,70,80 and 90%) and in milk chocolate are evaluated. Dark chocolates are confirmed as an excellent source of magnesium (252.2 mg/100 g) and iron (10.9 mg/100 g): in chocolate containing 90% cocoa, their content corresponds to, respectively, 67.0% and 80.3 of Nutrient Reference Values (NRV) in the European Union. The chocolate containing 90% cocoa is also a good source of zinc (3.5 mg/100 g), which is important for the immune system, and selenium (0.1 mg/100 g). Three main components suitable to explain the mineral concentrations are analyzed by factor analysis. The compone…
A white Maitake (Grifola frondosa): nutritional value and antibacterial preliminary activity test
2017
Grifola frondosa (Dicks.) Gray (Meripilaceae) is a big size, perennial, infrequent lignicolous basidiomycetes, traditionally known as Maitake. Brown or grayish overlapped caps, with a wavy margin, characterize the sporophore. In the wild, it is usually found at the base of living oak trees but it is also cultivated. G. frondosa is mainly distributed in Japan, Asia, Eastern America, and Europe. In Italy, is infrequent but widely distributed in all regions. Field investigation carried out in autumn 2016 in Sicily (southern Italy) permitted to observe an unusual white G. frondosa growing at the base of a living tree of Quercus pubescens Willd. s.l. Once harvested, the mushroom sample was clean…
