Dried pasta is the Italian food “par excellence”. Traditional foods have characteristics that can stimulate or evoke in the consumer sensorial stimuli and experiences, especially when these foods are consumed in a typical-traditional restaurant. Traditional restaurants can use sensory marketing as a promotional advantage, creating a unique and original atmosphere that can represent their main way of differentiation. The aims of this paper are to know consumer liking with regard to two high quality types of Sicilian pasta, common dried pasta, and whole-wheat pasta, consumed in three different venues of a typical-traditional Italian franchised restaurant, and to measure the influence of envir…

Calcium Ascorbate Coating Improves Postharvest Quality and Storability of Fresh-Cut Slices of Coscia and Abate Fétel Pears (Pyrus communis L.)

2022

Flesh firmness is closely related to fruit ripeness and is typically a reliable indicator of shelf-life potential so it could be considered a crucial quality index for the determination of pear quality. Flesh softening after cutting could considerably affect consumer acceptance of fresh-cut pears (Pyrus communis L.). Indeed, mechanical stress (cutting, peeling, etc.) could lead to ethylene production that results in the hydrolysis of pectic substances in the cell walls. The effectiveness of an edible coating treatment on the physical-chemical, nutraceutical, and sensorial analysis was evaluated on two pear cultivars: the summer-ripening ‘Coscia’ and the late-ripening ‘Abat…

CO2 uptake of Opuntia ficus-indica (L.) Mill. whole trees and single cladodes, in relation to plant water status and cladode age

2013

Most of net photosynthesis determinations in Opuntia ficus-indica come from measurements on individual cladodes. However, they have limitations when used to scale up to whole canopy gas exchange, because a large variability of carbon assimilation may occur within the canopy, due to, among others, differences in cladode age and intercepted radiation or individual cladode response to abiotic stresses. The aim of this work was to evaluate the application of open gas exchange chambers, simultaneously applied around the whole canopy, to measure net CO 2 uptake, continuously over a 24 h period, in single Opuntia ficus-indica (L.) Mill. potted trees and in relation with their water status. Net CO2…

Effect of low SO2 postharvest treatment on quality parameters of ‘Italia’ table grape during prolonged cold storage

2018

Table grape is a non-climacteric fruit with a low rate of physiological activity, very sensitive to water loss and fungal infection (Botrytis cinerea) during postharvest handling and cold storage. Gray mold is the most aggressive postharvest disease, because of its ability to develop at low temperatures, for that reason, it is standard practice to fumigate with sulfur dioxide (SO2) immediately after packing. ‘Italia’ table grape boxes were stored at 2°C for 4 months in a storage room with low concentrations of SO2 (0.20%) to extend their postharvest shelf life. Every 15 days, a sample of ‘Italia’ table grapes boxes was moved to 20°C for 3 days for the shelf life simulation. During storage, …
