Evaluación proximal y sensorial de pasta fettuccinie con sustitucion parcial con harina de setas Pleurotus ostreatus

Abstract

Pleurotus ostreatus is a saprophytic fungus that grows mainly on living or dead lignocellulose substrates, poor in nutrients and with low levels of minerals and vitamins. The propagation of this organism requires lignocellulose substrates. This fungus is edible with important functional properties. Because the population of trees located in the gardens of the Universidad de Ciencias y Artes de Chiapas generates a considerable amount of organic waste, these can be used as raw material for the cultivation of fungi. Two crops of the mushrooms were carried out in different substrates, the first from leaves of benjamina (Ficus benjamina) and the second was a combination of fig leaves (Ficus carica) and capulín (Prunus serotina). The edible mushrooms obtained from the crops were dehydrated by convection of hot air at 50°C for 24 hours, then ground and stored for disposal in the integration of edible paste formulations. This food has become a staple food because of its variety in processing and consumption, however, its protein content can be low and of poor quality; therefore, it is necessary to incorporate other sources of protein of better quality without altering eating habits or organoleptic characteristics. In this work we studied the nutritional composition and consumer acceptance that results with the addition of mushroom flour in the production of fettuccine pasta. Addition levels were 10% and 20% mushroom meal (hs), the chemical composition (raw protein, carbohydrates, fiber, fat and ash) of both formulations was analyzed based on the aoac (2000). The results indicated a considerable increase in the percentage compositions of fiber and protein when 20% hs was added to the fettuccine pasta formulation with respect to the reported sample without the addition of the mushrooms. In addition, the taste levels perceived by the sensory judges, for the attributes of smell and taste, were also high when 20% hs was incorporated with respect to the fettuccine control paste. This proposal can be considered useful for the preservation of mushrooms, since when dehydrated, despite the low yields, it can become an apt and versatile condiment, because it increases the nutritional components and improves the sensory properties of this type of food, without downplay the sustainable use of waste from plants in university gardens.

Prehispanic Foods Oyster Mushroom (<em>Pleurotus ostreatus</em>), Nopal (<em>Opuntia ficus-indica</em>) and Amaranth (<em>Amaranthus</em> sp.) as New Alternative Ingredients for Developing Functional Cookies

“…Pleurotus mushrooms have become a staple food because of the variety in processing and consumption. In previous studies, some Pleurotus species were investigated as food additives: (i) the addition of P. sajor-caju to selected wheat-and rice-based products [12]; (ii) the incorporation of oyster mushroom into biscuits in the range of 5-30% [13]; (iii) the production of Fettuccine pasta with partial replacement of wheat flour with P. ostreatus flour at 10% and 20% [14]; and (iv) sponge cakes supplemented with dried P. sajor-caju powder at 5%, 7%, 10% and 12% [15]. However, the use of Pleurotus spp.…”
