Fiordilatte Cheese Fortified with Inulin from or .

The influence of two different types of inulin added to fiordilatte cheese was assessed on product quality during the proper refrigerated storage period. To this aim, the fresh cheese was produced by a pilot plant, adding inulin, either from chicory (low degree of polymerization) or from cardoon (high degree of polymerization), during the stretching phase of the production process. Microbiological stability, sensory acceptability, texture and color changes of fortified dairy food during storage were measured and compared to the control cheese.

Strategies for fortified sustainable food: the case of watermelon-based candy.

The aim of this research was to design a new product, in particular a watermelon-based jelly candy, without generating waste. The study was divided in two steps: (i) optimization of candy formulation in terms of amount of rind, pulp and juice; (ii) fortification of the jelly candy with different concentrations of orange by-products (albedo and flavedo flours). The fortified jelly samples were assessed for sensory quality and chemical properties, before and after digestion.

Influence of different - addition on sensory and physicochemical aspects of .

Food industry produces considerable amounts of - that represent a severe problem from both economic and pollution points of view. The bioactive compounds still present in food - offer the possibility to re-use them to develop added value products. In the current work some - were incorporated into curd during production of Specifically, two concentrations (i.

Fruit and Vegetable By-Products to Fortify Spreadable Cheese.

In this work, spreadable cheese was enriched with flours from by-products (red and white grape pomace, tomato peel, broccoli, corn bran, and artichokes) as sources of fibres and antioxidant compounds. The physicochemical and the sensory properties of all the cheese samples were analysed. Results revealed that total phenolic content, flavonoids, and antioxidant activity of samples containing grape pomace significantly increased, followed by broccoli, artichoke, corn bran, and tomato peel by-products, compared to the control cheese.

Packaging optimisation to prolong the shelf life of fiordilatte cheese.

In this work, an active coating and modified atmosphere packaging (MAP) were investigated to prolong the shelf life of Fiordilatte packaged in traditional brine. First, the screening of MAP was performed in order to select the best gas composition. Then, the combined effect of MAP and coating was investigated.

In vitro and in vivo application of active compounds with anti-yeast activity to improve the shelf life of ready-to-eat table grape.

The anti-yeast effects of several compounds at different concentrations were screened in vitro against main table grape spoilage yeasts. The compounds showing the most significant anti-yeast activity were applied by dipping to table grape, to evaluate the sensory perception. In a subsequent final step, dipping treatments with potassium sorbate, eugenol, citrus extract and ethanol, were applied to ready-to-eat seedless table grape, packaged in air or under modified atmosphere packaging (MAP).

Food applications of natural antimicrobial compounds.

In agreement with the current trend of giving value to natural and renewable resources, the use of natural antimicrobial compounds, particularly in food and biomedical applications, becomes very frequent. The direct addition of natural compounds to food is the most common method of application, even if numerous efforts have been made to find alternative solutions to the aim of avoiding undesirable inactivation. Dipping, spraying, and coating treatment of food with active solutions are currently applied to product prior to packaging as valid options.

Synergic antimicrobial activity of lysozyme, nisin, and EDTA against Listeria monocytogenes in ostrich meat patties.

Unlabelled: Synergic antimicrobial activity of lysozyme (250 ppm), nisin (250 ppm), and disodium ethylenediamine tetraacetic acid (EDTA) (20 mM) against Listeria monocytogenes and meat-borne spoilage bacteria in ostrich patties packaged in air and vacuum was studied. The antimicrobial treatment decreased the L. monocytogenes population in ostrich patties below the official limit of the European Union (<2 log CFU/g).

Use of lysozyme, nisin, and EDTA combined treatments for maintaining quality of packed ostrich patties.

Unlabelled: The antimicrobial effectiveness of lysozyme, nisin, and ethylene diamine tetraacetic acid (EDTA) combination treatments (Mix(1): 250 ppm lysozyme, 250 ppm nisin, 5 mM EDTA; Mix(2): 500 ppm lysozyme, 500 ppm nisin, 5 mM EDTA) on bacterial growth of ostrich patties packaged in air, vacuum, and 2 different modified atmospheres (MAP(1): 80% O(2), 20% CO(2); MAP(2): 5% O(2), 30% CO(2), 65% N(2)) was evaluated. Moreover, the lipid oxidation was evaluated as well as color and sensory characteristics. The growth of total viable counts and lactic acid bacteria were strongly inhibited by the antimicrobial treatments in all the running time (Inhibition Index >97%) whereas for Enterobacteriaceae and Pseudomonas spp.

Combined effects of thymol, carvacrol and temperature on the quality of non conventional poultry patties.

The combined effect of thymol (0-300ppm), carvacrol (0-300ppm), and temperature (0-18°C) on the quality of non conventional poultry patties packaged in air and modified atmosphere (MAP: 40% CO(2;) 30%O(2); 30% N(2)) was investigated using a simplex centroid mixture design. The patties were monitored for microbiological (total viable count, Enterobacteriaceae, lactic acid bacteria, Pseudomonas spp.) physico-chemical (pH, colour) and sensory attributes.
