Evaluating free school fruit: results from a natural experiment in Norway with representative data
2014
AbstractObjectiveTo assess impacts of the nationwide Norwegian School Fruit Scheme (NSFS) using nationally representative data.DesignThe NSFS is organized such that primary-school children (grades 1–7) are randomly assigned to one of three school fruit arrangements: (i) the child receives one free fruit or vegetable per day; (ii) the child is given the option to subscribe to one fruit or vegetable per day at a subsidized price; and (iii) the child attends a school that has no school fruit arrangement.SettingData from an Internet survey are used to compare child and parental fruit and vegetable intakes across the three NSFS groups focusing mainly on groups (i) and (iii). The analysis was con…
An international case-control study of maternal diet during pregnancy and childhood brain tumor risk: a histology-specific analysis by food group.
2009
Maternal dietary data from an international collaborative case-control study on childhood brain tumors were used to evaluate associations between histology-specific risk and consumption of specific food groups during pregnancy.Nine study centers from seven countries contributed 1218 cases and 2223 controls. Most cases were diagnosed between 1982 and 1992 and ranged in age from 0 to 19 years. Dietary consumption was measured as average grams per day.Foods generally associated with increased risk were cured meats, eggs/dairy, and oil products; foods generally associated with decreased risk were yellow-orange vegetables, fresh fish, and grains. The cured meat association was specific to astroc…
Effect of Gibberellic Acid on Growth, Yield, and Quality of Leaf Lettuce and Rocket Grown in a Floating System
2019
Gibberellins (GAs) are growth hormones strongly involved in a wide variety of physiological activities. Currently, gibberellins are commercially used to enhance phenotypic characteristics, earliness, and productivity of many vegetable and ornamental crops. In this work, the efficacy of supplementation of low levels of gibberellic acid (0, 10&minus
EFFECT OF HOT AIR TREATMENT ON MINIMALLY PROCESSED CAULIFLOWER
2013
The request of minimally processed vegetable is continuously increasing, and there is a growing interest for new fresh cut products. Cauliflower, as other cabbages, is highly appreciated for its nutritional value due to the good content of vitamins, antioxidants and anti-carcinogenic compounds. It is suitable to be used as a minimally processed vegetable, but harvesting and the following processing can cause a severe stress determining the appearance of accelerated senescence symptoms. The aim of the present work was to investigate the effect of hot air treatment and cold storage on minimally processed green cauliflower. Fresh-cut cauliflower florets put in sealed PE bags were treated at 48…
Effect of high hydrostatic pressure (HPP) and pulsed electric field (PEF) technologies on reduction of aflatoxins in fruit juices
2021
Abstract The high demand of fresh-like products to meet the fruits and vegetables serving encouraged the implementation of non-thermal food processing techniques, such as high pressure processing (HPP) and pulsed electric fields (PEF), with low impact on nutritional components. The aim of the present work is to evaluate the application of HPP and PEF techniques as useful decontamination tool for aflatoxins (AFs) reduction in grape juice. Spiked grape juice samples with AFs treated by PEF or HPP were extracted using dispersive liquid-liquid microextraction (DLLME) and determined by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS-IT). Reduction percentages of 14–29% have b…
Effect of nitrogen fertilizer level on quality and shelf-life of fresh cut Swiss chard
2018
Swiss chard (Beta vulgaris L. var. cicla L.) is a leafy vegetable highly appreciated in some areas for its nutritional properties and year round supply. Its production area is not commercially important, but this minor vegetable offers an interesting enlargement of the current vegetable assortment by using its stalks and leaves. Swiss chard is a very nutritive demanding species. The content of mineral elements, total quality and yield are influenced by the amount, frequency and method of fertilization. The aim of this study was to evaluate the effect of high or low levels of nitrogen fertilization on the quality and shelf-life of minimally processed Swiss chard. Plants grown with a high (18…
Il ruolo delle Tecnologie Informatiche e di Comunicazione e della logistica distributiva sulla competitività del comparto ortofrutticolo siciliano
2012
In recent years, the market globalization process has deeply changed the international competitive background, leading, inevitably, to a revision of the strategies and the organization structures of the companies. It is now widely accepted that Information and Communication Technology (ICT) and supply chain logistics management, have an important role in the increasing of the competitive potential of each company and in the development of entire economic sectors. The importance of these factors in the business strategies of the firms, has generated an increasing attention by the research world to the study of the economic and social impact, both about the spread of modern information and co…

Children’s Fruit and Vegetable Preferences Are Associated with Their Mothers’ and Fathers’ Preferences
2021
Children’s preference for fruit and vegetables must emerge during childhood. At children’s homes, mothers and fathers influence children’s developing food preferences with their own preferences and actions. The purpose of the study was to reveal the association parents have with their children’s fruit and vegetable preferences. The study was conducted in a sample of Finnish mothers and fathers of 3–5-year-old children. The participants were recruited, and questionnaires distributed through early childhood education and care centers in 2014 and 2015. The results showed considerable variance in the children’s preferences, and were more similar with their father’s, than their mother’s preferen…
