A Potentially Ecosustainable Hazelnut/Carob-Based Spread.

Commercial cocoa and hazelnut-based sweet spreads typically present a poor nutribiochemical level due to their ingredients and recipes, while nowadays, there is the need of developing sustainable food products addressing both an improved nutritional and environmental profile. The aim of this work was then to develop an innovative hazelnut/carob-based spread with potential high sustainability and nutritional profile, including the exploitation of grape-processing residues (grape skin flour and grapeseed oil) and carob pulp as cocoa surrogate. Rheological (rotational/oscillatory), oxidative, and thermal features of the spread were assessed and compared with two commercial nut-cocoa-based products.

Effect of different fibre addition on cookie dough and texture.

Different commercial fibres from bamboo (BAM), cocoa (COC), psyllium (PSY), chokeberry (ARO) and citrus (CIT) were characterized for technological (oil- and water-holding capacity, solubility and bulk density) and physical (moisture, colour and particle size) features and added to a cookie recipe. The doughs were prepared using sunflower oil and white wheat flour was substituted with 5% (w/w) of the selected fibre ingredient. The attributes of the resulting doughs (colour, pH, water activity and rheological tests) and cookies (colour, water activity, moisture content, texture analysis and spread ratio) were compared to control doughs and to cookies made with refined flour and whole flour formulation.

Citrus Peel Extracts for Industrial-Scale Production of Bio-Based Active Food Packaging.

The thermal stability of four different commercial citrus peel extracts was tested and improved by an encapsulation process with β-cyclodextrins in a spray-dryer. All extracts after the encapsulation process maintained a good antioxidant capacity, with an apparent loss in total phenolic compounds of around 20-25%. In addition, all samples showed good antimicrobial activity (MIC 5-0.

Effect of Dietary Fiber and Thermal Conditions on Rice Bran Wax-Based Structured Edible Oils.

In this work, extra-virgin olive oil (EVO)- and sunflower oil (SFO)-based oleogels were structured using rice bran wax (RBW) at 10% by weight (/). Bamboo fiber milled with 40 (BF), 90 (BF) and 150 (BF) µm of average size was added as a structuring agent. The effect of fiber addition and cooling temperature (0, 4, and 25 °C) on thermal and structural parameters of achieved gels was assessed by rheological (both in rotational and oscillatory mode), texture, and differential scanning calorimetry tests.

Rheological and tribological characterization of different commercial hazelnut-based spreads.

Five commercial hazelnut/cocoa spreads with different compositions were tested by rheology/tribology. The impact of each formulation on the structural/lubricant performances was investigated. Rotational/oscillatory rheology was chosen to assess material behavior during flow.

Nutritional, physical and sensory characteristics of gluten-free biscuits incorporated with a novel resistant starch ingredient.

Gluten-free (GF) biscuits were prepared by replacing part of a GF flour mix (GFM) with 0, 15, 30 and 45 g/100 g (total flour) with a novel resistant starch-rich ingredient obtained from annealed white sorghum starch (RSWS). The chemical composition, physical characteristics, in vitro starch digestion and sensory evaluation of biscuits were considered. The chemical composition of samples was influenced by the addition of the RSWS.

Genome-Assisted Characterization of , and Strains Isolated from Sorghum as Starters for Sourdough Fermentation.

Sourdough fermentation of bakery products is a well-established and widespread technique to confer an added value to the resulting food. In recent decades, gluten-free raw materials have gained more attention due to the diffusion of food disorders such as coeliac disease, but, at the same time, they present difficult manipulation and scarce technological properties because of the absence of gluten. For this reason, the present work was aimed at selecting starter cultures for sourdough application that are isolated from fermentation of sorghum flour.

Enrichment of Whole Wheat Cocoa Biscuits with Encapsulated Grape Skin Extract.

Grape pomace is one of the major waste products generated by the wine-making process and it contains seeds and skins still rich in bioactive compounds. Skins can be separated from the seeds and valorised for the recovery of antioxidant extracts with different potential applications. The aim of this study was to evaluate the influence of the addition of an extract obtained from waste grape skins and encapsulated in maltodextrins on the antioxidant properties and sensory acceptability of whole wheat cocoa biscuits.

Waste grape skins: evaluation of safety aspects for the production of functional powders and extracts for the food sector.

Skin powders and aqueous alcohol extracts were obtained from waste marcs from different grape varieties (Barbera, Nebbiolo, Pinot Noir, Chardonnay, Moscato and Müller-Thurgau). Both skins and extracts were analysed for the content of chemical contaminants: ochratoxin A (OTA), biogenic amines (BIAs), pesticides and metals. OTA was detected in low concentrations in Barbera, Moscato and Nebbiolo skins, but only in Barbera and Moscato extracts.
