ABSTRACT Two spray dryers were tested to obtain powders from concentrated juices of blackcurrant, apricot, raspberry, with different maltodextrins as drying-aid agents. Composition of fruit juicesExpand
Flavor Encapsulation by Spray Drying: Application to Citral and Linalyl Acetate
Leaflash spray drying technique was used to encapsulate a mixture of two volatile products, citral and linalyl acetate in the proportion of 80:20 (w/w). The support materials were gum arabic andExpand
Variability of the response of 66Listeria monocytogenesandListeria innocuastrains to different growth conditions
Differences between strains in lag phase duration were much greater than in growth rate, and the variability observed among strains raises questions about the consequences in quantitative risk assessment and about the construction of models in predictive modelling. Expand
Traditional dry fermented sausages produced in small-scale processing units in Mediterranean countries and Slovakia. 1: Microbial ecosystems of processing environments.
The variability of the residual contamination emphasized the different cleaning, disinfecting and manufacturing practices routinely followed by these small-scale processing units regularly colonised at various levels by spoilage and technological microflora with excessive contamination levels in some of the PUs.

Predicting variability of ageing and toughness in beef M. Longissimus lumborum et thoracis.
There was a wide variability in tenderness in M. Longissimus lumborum et thoracis from similar animals and variations in metabolism and enzyme activity controlled by inhibitors and calpains appear to be largely responsible for this variability. Expand
Roles of superoxide dismutase and catalase of Staphylococcus xylosus in the inhibition of linoleic acid oxidation.
Both catalase and SOD of S. xylosus contributed to the inhibition of lipid oxidation as measured by measuring the volatile organic compounds and the conjugated diene hydroperoxides arising from linoleic acid oxidation. Expand
Modelling the growth of Listeria monocytogenes in dynamic conditions.
The results showed the capacity of the recurrent neural network to predict growths carried out in different experimental conditions without using those used for its elaboration. Expand
Recommendations for calculating growth parameters by optical density measurements
An automated turbidimetric system, Bioscreen C, was used to monitor bacterial growth in microplates. The detection threshold and linear range of the instrument were determined. Bioscreen C was foundExpand
Modelling the behaviour of Listeria monocytogenes in ground pork as a function of pH, water activity, nature and concentration of organic acid salts
Aims:  to study and model the effect of sodium acetate, sodium lactate, potassium sorbate and combination of acid salts on the behaviour of Listeria monocytogenes in ground pork.
Effect of Temperature and pH on Growth of Staphylococcus aureus in Co-Culture with Lactococcus garvieae
The results argue in favor of adding antagonist strain early in the cheese-making process by removing S. aureus from co-culture with Lactococcus garvieae as a function of incubation temperature and pH values. Expand
