Effect of pretreatments and drying processo on health-promoting components of goji berries
2020
Drying is one of the most common preservation methods used to extend the shelf life of fruits and vegetables by reducing water content so as to prevent the growth and reproduction of microorganisms and to inactivate many of the moisture-mediated alterative reactions. Goji berries are mainly consumed dried. Several methods can be used to dry goji berries, such as sun drying, hot air drying, vacuum drying, and freeze drying. In this chapter the most used pre-treatment and drying processes found in literature on goji berries are described, together with their effect on their health promoting components, such as carotenoids, tocols, vitamin C, flavonoids and phenols. Moreover the effect of diff…
Growth performance in heavy lambs experimentally treated with 17 β-estradiol
2012
European and Italian legislation have banned use of growth promoters in livestock since 1988, but epidemiological data show that anabolic drugs are still being used illegally. Recent surveys carried out on the cattle farms in Northern Italy have confirmed the presence of growthpromoting hormones. Authors report data on growth performances in 80 Valle del Belice×Comisana weaned lambs experimentally treated with 17 beta-estradiol with 0.5 ml solution of oil Depot Estradiol ® (containing 5 mg of 17β- estradiol valerate) by intramuscular injection into the thigh. The experiment was founded by the National Ministry of Health, to validate histological test for surveillance and control of growth-p…
Terapia gruppo-analitica
2006
Il lavoro propone i risultati di una ricerca sulla valutazione empirica di una psicoterapia di gruppo costruita nello spirito di un’osservazione complessa, che aiutasse a mettere in luce molteplici sfaccettature del processo terapeutico e che consentisse una conoscenza non riduttiva dell’esperienza terapeutica stessa. L’attenzione della ricerca è stata rivolta, oltre che ai percorsi terapeutici dei singoli pazienti, allo specifico dispiegarsi dei processi gruppali, alla possibilità di aumentare la comprensione su come tali processi si caratterizzano ed evolvono nel tempo. Oggetti dell’indagine sono stati: l’esplorazione del processo di gruppo, ed in particolare la configurazione della matri…
Agroecological engineering
2015
Earth has recently entered the new era of the Anthropocene, during which the rise of human activities are impacting for the first time ecosystems and climate on the global scale. Since the 1960s the green revolution has improved food production in quantity using industrially-designed agriculture, which has led to global pollution by pesticides and losses of food quality, biodiversity and soil carbon. As a consequence there is a need to implement agroecological practices in order to produce food safely and in a sustainable way. This virtual issue presents principles and applications of agroecological engineering, exemplified in 19 selected review articles from the journal Agronomy for Sustai…
Lentil Fortified Spaghetti: Technological Properties and Nutritional Characterization
2021
Lentil (Lens culinaris), consumed as a part of the diet worldwide, is a functional dietary ingredient that plays a function in human nutrition as a rich source of bioactive nutrients (low quantities of fat, sodium, and vitamin K
Study of Water Distribution, Textural and Colour Properties of Cold Formulated and Air-Dried Apple Snacks
2022
Vacuum impregnation is considered a cold formulation technology since it allows the incorporation of a desired functional compound into porous plant tissue without applying any heat. It is widely used in combination with the drying process to obtain added-value snacks. The aim of this work was to evaluate the effect of two trehalose concentrations (5 and 10% w/w) on: (i) the water state and texture evolution during the air drying (50 °C, 8 h) of apple snacks vacuum impregnated with blueberry juice, and on (ii) the colour of the final dried apple snacks. The results of nuclear magnetic resonance (NMR) showed that trehalose affects the water mobility of the samples during drying especially af…

High Pressure Processing Impact on Emerging Mycotoxins (ENNA, ENNA1, ENNB, ENNB1) Mitigation in Different Juice and Juice-Milk Matrices
2022
The aim of the present study was to investigate the potential of high-pressure processing (HPP) (600 MPa during 5 min) on emerging mycotoxins, enniatin A (ENNA), enniatin A1 (ENNA1), enniatin B (ENNB), enniatin B1 (ENNB1) reduction in different juice/milk models, and to compare it with the effect of a traditional thermal treatment (HT) (90 °C during 21 s). For this purpose, different juice models (orange juice, orange juice/milk beverage, strawberry juice, strawberry juice/milk beverage, grape juice and grape juice/milk beverage) were prepared and spiked individually with ENNA, ENNA1, ENNB and ENNB1 at a concentration of 100 µg/L. After HPP and HT treatments, ENNs were extracted from treate…
Dried-Fruit Storage: An Analysis of Package Headspace Atmosphere Changes
2019
The quality of packaged dried foods depends on storage conditions and is determined largely by the initial gas composition inside and the transference through the container. The aim of this work was to analyze the O2 and CO2 concentrations within the internal atmosphere of the packaging. In this study, dried apricots and raisins were packaged in glass jars and polypropylene trays thermosealed with different polymers, and stored at 5, 15, 25, and 35 °
