Green solvents and Ultrasound-Assisted Extraction of bioactive orange (Citrus sinensis) peel compounds.
2019
AbstractByproducts such as orange peel have potential uses because of their bioactive compounds, which are important for their potential to reduce the risk factors of diseases caused by aging. The lack of effective techniques and the high levels of pollution produced by the conventional extraction of bioactive compounds using organic solvents have highlighted the need to enhance the ‘green chemistry’ trend. This study evaluates the use of ultrasound to extract bioactive compounds from orange peel. The antioxidant capacity, phenolic content, ascorbic acid, total carotenoids, and HPLC profile of phenolic compounds from orange peel extracts were obtained by a physicochemical evaluation. The re…
Study of Consumer Preferences in Regard to the Blonde Orange Cv. Washington Navel “Arancia Di Ribera PDO”
2016
Consumers’ attitude and preferences in regard to food ingre- dients, country of origin, social corporate responsibility toward the environment, and work conditions have changed over the last 10 years. Consumers are getting more educated and there- fore more sensitive around cultivation practices in agriculture and food processing, which increases concerns in regard to production practices in agriculture. Several studies have been conducted on consumers’ preferences about quality food, but not with regard to blonde oranges cv. Washington Navel culti- vated in southern Italy. This quality fruit is a niche product that achieved the Protected Designation of Origin (PDO) certifica- tion for high…
St. Augustinegrass accessions planted in northern, central and southern Italy: Growth and morphological traits during establishment
2018
The use of warm season turfgrasses is a consolidated trend in the climatic transition zone of Mediterranean countries, in particular St. Augustinegrass (Stenotaphrum secundatum (Walt.) Kuntze) begins to be widespread in warm coastal areas. However, little is known about the performance of the different cultivars of this species in southern Europe. In 2016-2017 a trial was carried out in three locations in Italy, Padova, Pisa, and Palermo, located in the north, center and south of the country respectively. Four cultivars (Floratine, Captiva, Sapphire, Palmetto) and five ecotypes (CeRTES 201, CeRTES 202, CeRTES 203, CeRTES 204, CeRTES 205) were compared in terms of their growth characteristic…
Seashore paspalum in the Mediterranean transition zone: phenotypic traits of twelve accessions during and after establishment
2017
The use of warm-season turfgrasses is consolidated in the transitional areas of Mediterranean countries and some field trials have provided information on the adaptability of seashore paspalum to Mediterranean environment. Nonetheless, little is known on the performance of the different commercial cultivars of <em>Paspalum vaginatum</em> in this climatic zone. Furthermore, considering the high degree of variability of this species, ecotypes have the potential to supply new plant material with desired turf characteristics. The research aimed at comparing growth characteristics and morphological traits of eight commercial cultivars of seashore paspalum (Platinum, Salam, SeaDwarf, …
Orange proteomic fingerprinting: From fruit to commercial juices.
2015
Combinatorial peptide ligand library technology, coupled to mass spectrometry, has been applied to extensively map the proteome of orange pulp and peel and, via this fingerprinting, to detect its presence in commercial orange juices and drinks. The native and denaturing extraction protocols have captured 1109 orange proteins, as identified by LC-MS/MS. This proteomic map has been searched in an orange concentrate, from a Spanish juice manufacturer, as well as in commercial orange juices and soft drinks. The presence of numerous orange proteins in commercial juices has demonstrated the genuineness of these products, prepared by using orange fruits as original ingredients. However, the low nu…
Employ of Citrus By-product as Fat Replacer Ingredient for Bakery Confectionery Products
2020
Citrus fruits processing is one of the foremost industrial activities in Sicily and the main residual by-product consists in peels and seeds (known as "pastazzo"). Traditionally this by-product has been used for different purposes, and only most recently, it has been described as source of a wide range of healthy bioactive compounds and dietary fibers. In the present work, a debittered food grade orange fiber (DOF), extracted from orange juice by-product, was experimentally obtained and tested as fat-replacer at different percentages (30, 50, and 70%) in bakery confectionery products (brioches). The DOF showed high total fiber content, low water activity and a high water binding capacity. T…
Colour as a driver of Pinot noir wine quality judgments: An investigation involving French and New Zealand wine professionals
2016
Despite anecdotal reports suggesting an influence of perceived wine colour on wine professionals’ judgments of wine intrinsic quality, there is a lack of empirical evidence on the phenomenon. The major aim of the present study was to investigate the importance of perceived colour as a driver of chemosensory judgments of Pinot noir wines including sensory evaluations of quality and typicality. Twenty-three French and 23 New Zealand (NZ) wine professionals judged Pinot noir wines from France and NZ on a range of attributes including perceived colour (hue, intensity, and brightness), varietal characteristics, and overall wine quality. The wines were evaluated in both standard clear glassware w…
On the consistency of liking scores : insights from a study including 917 consumers from 10 to 80 years old
2004
Preference for 7 orange juices was recorded monadically. Three of the samples were replicates of the same juice (RJ). The 4 other samples were RJ slightly spiked with either sucrose, or citric acid, or quinine or an orange flavor. Each subject then performed a paired preference test composed of RJ and the modified juice whose score was the furthest from the RJ score. Finally, subjects were asked to choose one among 8 reasons why they preferred that sample. A number of individual statistics were computed in order to compare the consistency of liking scores within session, across ages and between genders. Women were slightly more consistent than men. However, no significant effect of age nor …

Fragrant bioethanol: A valued bioproduct from orange juice and essential oil extraction
2018
Abstract We identify the composition of a less known, yet important bioproduct obtained in relatively high amount during orange fruit processing for juice and essential oil extraction comprised of bioethanol dissolving valued terpenes. Green cosmetic, perfume and biosolvent applications are anticipated.
