Influence of Degradative Enzymatic Activities on the Shelf Life of Ready-to-Eat Prickly Pear Fruits
2012
Prickly pear fruit (Opuntia ficus indica L. Miller) belongs to the Cactaceae family. This species is very sensitive to low storage temperatures (< 5°C) which cause damages. The fruits can be peeled, suitably packaged and successfully commercialized as a ready-to-eat product. The main limit to the extension of the shelf life is the production of off-flavors due to different factors, the growth of microorganisms and the action of endogenous enzymes. Lipoxygenase (LOX) and Pectinesterase (PE) are involved in fruit degradation. In particular, LOX pathway is directly responsible for lipid oxidation, and the subsequent production of off-flavours, while PE causes the softening of fruit during m…
ANALYSIS OF CORRELATION BETWEEN TAX REVENUES AND OTHER ECONOMIC INDICATORS IN EUROPEAN UNION MEMBER STATES
2014
This paper aims to identify the presence or absence of a connection between some factors that influence the evolution of tax revenue in the EU and to quantify its intensity using Pearson correlation coefficient. Testing the bivariate correlation between tax revenues and a range of 15 causal factors lead to a division of variables that determine the evolution of tax revenues into three categories: significant factors such as GDP, net national income per capita, gross added value, gross salary, current account balance, less significant factors of tax revenue such as the employment rate, public expenditures, public debt, and foreign direct investment, and non-factors of tax revenues such as un…
Pulsed flow-through cultivation of Margaritifera margaritifera : effects of water source and food quantity on the survival and growth of juveniles
2020
AbstractConservation of the endangered freshwater pearl mussel (FPM) includes artificially rearing juveniles, but the pulsed flow-through (PFT) method, enabling the continuous renewal of water and food in culture containers, has not been applied to FPM. This study tested the PFT method in culture of FPM juveniles, and the effect of water source (tap vs well water) and food concentration (mixture of commercial phytoplankton products) on the survival and growth of juveniles. Beaker-specific survival rates varied from 0 to 100% (mean: 34%) and from 0 to 58% (mean: 16%) in the 1st (2-week) and 2nd (10-week) experiment, respectively. In the 1st experiment, juveniles attained statistically signif…
