    Effects of polyols at low concentration on the release of sweet aroma compounds in model soda beverages
    (Elsevier, 2024) Barba González-Albo, Carmen; Angós Iturgaiz, Ignacio; Maté Caballero, Juan Ignacio; Cornejo Ibergallartu, Alfonso; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Institute for Advanced Materials and Mathematics - INAMAT2; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
    This study investigated the effect of polyols erythritol, D-mannitol, and maltitol on the volatility of aroma compounds γ-butyrolactone, 3-methyl-1-butanol, and 2-phenylethanol in aqueous solution. Headspace solidphase microextraction/gas chromatography and diffusion-ordered nuclear magnetic resonance techniques were used to obtain information on aroma–food matrix interaction. Results demonstrated that adding polyols at final low concentrations of 5% or 10% (w/w) to an aqueous solution of 2-phenylethanol reduced the release of vapor-phase aromas, except in the case of 3-methyl-1-butanol, which was not affected by the presence of polyols in the liquid matrix. Polyols also reduced the diffusion coefficients of all three aroma compounds, probably due to friction between the molecules. At low polyol concentrations, aroma compound volatility and diffusion coefficient values were altered compared to those of aromas released from pure water. This observation is related to the physicochemical properties of the aroma compounds. These insights may help guide the use of the combination of aroma compounds and polyols in the formulation of sugar-free and reduced-sugar beverages. Chemical compounds: γ-butyrolactone (PubChem CID: 7302), 3-methyl-1-butanol (PubChem CID: 31260), 2-phenylethanol (PubChem CID: 6054), erythritol (PubChem CID: 222285), D-mannitol (PubChem CID: 6251), maltitol (PubChem CID: 493591).

    Combined effect of antimicrobial edible coatings with reduction of initial microbial load on the shelf-life of fresh hake (Merluccius merluccius) medallions
    (Wiley, 2019) Otero Tuárez, Víctor Oswaldo; Carrión Granda, Ximena; Fernández Pan, Idoya; Fernández García, Teresa; Maté Caballero, Juan Ignacio; Agronomía, Biotecnología y Alimentación; Agronomia, Bioteknologia eta Elikadura
    Two distinct strategies were combined to preserve fresh fish (Merluccius merluccius) under refrigeration at 4 °C for 12 days: (i) the application of an antimicrobial edible coating enriched with oregano essential oil (OEO) or carvacrol (CV) and (ii) the reduction of initial microbial load by good handling practise and the use of sodium hypochlorite (NaOCl). The action of antimicrobial coatings alone retarded the growth of Enterobacteriaceae, lactic acid bacteria (LAB) and H2S producing bacteria on fish samples. The reduction of initial microbial load by itself only affected the evolution of LAB, but not the rest of the bacterial groups. When using both techniques combined, edible antimicrobial coatings were significantly more effective with additional and significant delays in the growth of mesophilic, psychrotrophic and Pseudomonas bacteria. Thus, the use of both strategies combined resulted in a reduction of the counts of all bacterial groups after 12 days of storage which ranged from 1.5 log and 8 log, in Pseudomonas and H2S producing bacteria, respectively. Moreover, no significant differences were observed when comparing the microbiological evolution of samples treated with OEO compared to those only treated with CV.

    Effect of curcumin, betanin and anthocyanin containing colourants addition on gelatin films properties for intelligent films development
    (Elsevier, 2021) Etxabide Etxeberria, Alaitz; Maté Caballero, Juan Ignacio; Kilmartin, Paul A.; Agronomia, Bioteknologia eta Elikadura; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Agronomía, Biotecnología y Alimentación
    About 52 Mt of food waste is generated annually at the household level. Almost a quarter of this waste is related to packaging issues such as inaccurate data labelling systems. This shows the crucial need to replace or improve food data labels in order to reduce food waste. Gelatin films with different concentrations of curcumin, betanin and anthocyanin containing colourants were prepared by casting. The effect of different concentrations of colourants on the optical, barrier, physicochemical, structural and colour response properties of films was investigated. The addition of colourants altered the colour, light barrier, and wettability of the films. Although the colourant retention capacity of films varied as a function of colourant type, no changes were observed in infrared spectra, and likewise the similar results were obtained by X-ray diffraction, mechanical testing and scanning electron microscopy pointed to retention of tertiary and inner structural properties of the films. The addition of colourants provided films with the capacity to sense pH changes before and after immersion in a fatty food simulant. These properties establish the suitability of the films for intelligent fatty food packaging applications.

    Effect of antimicrobial edible coatings and modified atmosphere packaging on the microbiological quality of cold stored hake (Merluccius merluccius) fillets
    (Hindawi / Wiley, 2018) Carrión Granda, Ximena; Fernández Pan, Idoya; Rovira, Jordi; Maté Caballero, Juan Ignacio; Tecnología de Alimentos; Elikagaien Teknologia
    The effect of whey protein isolate (WPI) coatings incorporated with essential oils (EOs) and combined with modified atmosphere packaging (MAP) on the microbiological quality of fresh hake fillets was evaluated. Fresh hake fillets were coated with different formulations of WPI-EO coatings and packaged under air and MAP conditions (50% CO2/45% N2/5% O2).When WPI-enriched films were applied with or without the presence of MAP over hake fillets with a high initial microbial population, a limited but significant effect on the microbial growth was observed. This effect was more intense on Enterobacteriaceae and H2S-producing bacteria. When hake fillets with lower initial microbial counts were treated, a more intense antimicrobial effect was observed and a synergistic effect between WPI-EO coatings and MAP was detected. A significant extension of the lag phase and reduction, primarily, on the total viable counts and H2S-producing bacteria, was detected, doubling the shelf-life of hake fillets compared with control samples.The initial microbial load of the samples is a key factor influencing the effectiveness of the treatment.The obtained results demonstrated the effectiveness of this combined strategy as a promising alternative for enhancing the microbial quality of fish products during storage at refrigeration temperatures.

    Characterization of glucose-crosslinked gelatin films reinforced with chitin nanowhiskers for active packaging development
    (Elsevier, 2022) Etxabide Etxeberria, Alaitz; Kilmartin, Paul A.; Maté Caballero, Juan Ignacio; Gómez-Estaca, Joaquín; Agronomía, Biotecnología y Alimentación; Agronomia, Bioteknologia eta Elikadura
    To find renewable and sustainable alternatives to reduce the severe environmental impact of single-use synthetic plastic packaging, glucose-crosslinked gelatin films containing different amounts of chitin nanowhiskers (CNWs) were prepared. CNWs were first prepared by acid hydrolysis of chitin from shrimps, and characterized (morphological and thermal properties), before their addition into film-forming formulations. The films were heat-treated to promote the chemical crosslinking Maillard reaction (MR), between glucose and gelatin. The films then became less soluble (from 100% to ∼10%), thermally more stable, had a notably improved UV–vis light absorption capacity, and presented significantly enhanced tensile strength (from 42 to 77 MPa) and Young's modulus (from 1476 to 2921 MPa), however, they also became less flexible (from 17% to 7%) and transparent. These property alterations were mainly related to changes in crystallinity, the MR and to a lesser extent, to the formation of noncovalent (electrostatic and hydrogen bonding) interactions between CNWs and gelatin. Furthermore, due to the formation of MR products, the films turned yellow/dark brown and released antioxidant compounds (inhibition ∼33%) while immersed in water, which gave the films their active properties (stabilization of free radicals). These films have considerable potential as reinforced active packaging films for renewable food packaging applications.

    Strategies to reduce purge losses in meat products stuffed in plastic casings
    (Hindawi, 2023) Flores González, Tatiana; Rojas-Graü, Alejandra; Maté Caballero, Juan Ignacio; Esparza, Jesús; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
    Two different meat emulsions were prepared with different physical stability: R1 with 6.28 ± 1.13% total expressible fluid and R2 with 17.7 ± 1.48%. The emulsions were placed in plastic casings at three different surface tensions (ST), expressed as contact angle, and three distinct overstuffing percentages (OS). The stuffed samples were cooked in an industrial oven. After cooling, purge losses (PL) and texture profile analysis (TPA) were measured. The reduced surface tension of the plastic casings significantly decreased the PL of both recipes. In the case of R2, a combination of high OS and low ST was necessary to reduce PL in a 60%. In the case of TPA, OS had a statistical influence on parameters like chewiness, cohesiveness, and hardness. Plastic casings with different surface tension (to increase adherence of meat emulsion to the casing) stuffed at different levels of overstuffing percentages (to reduce free space between meat emulsion and casing) represent a potential tool to reduce PL of products based on low stability meat emulsions.

    Evolution of microbial and protein qualities of fractions of milk protein processed by microfiltration
    (Elsevier, 2022) Galarza Iriarte, Uxue; Iturmendi Vizcay, Nerea; García Amezketa, Arantza; Fernández García, Teresa; Maté Caballero, Juan Ignacio; Agronomia, Bioteknologia eta Elikadura; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Agronomía, Biotecnología y Alimentación; Gobierno de Navarra / Nafarroako Gobernua
    In dairy industry there has always been great concern about the microbial and protein quality of liquid milk protein fractions obtained by microfiltration (MF). The objectives of research were to study the impact of MF on the evolution of protein and microbial quality of microfiltered milk (MFM), liquid micellar casein concentrates (LMCC) and serum permeates (SP) during storage at 4 °C. This study was carried out with three different batches of milk using diafiltration. Samples were characterized by physicochemical properties; evolution of microbial load and protein (RP-HPLC). Ceramic MF (pore size 1.4 μm) did not change the protein profile, but reduced microbial load by up to 2 log CFU/mL. Polymeric MF (pore size 0.1 μm) was not a sterilizing process since all samples from the permeate presented bacterial growth after 6 days. Protein degradation was observed after 13 days at 4 °C in all studied products. Caseins (CN) were much more affected than whey proteins. β-CN A2 content was reduced by 25–50%, αs1-CN by 30% and β-CN A1 by 10–30%.; κ-CN was the most stable casein. The contents of the whey proteins remained unaltered for 21 days. Protein degradation was likely due to the action of endogenous and bacterial enzymes.

    Aflatoxin B1 detoxification potentials of garlic, ginger, cardamom, black cumin, and sautéing in ground spice mix red pepper products
    (MDPI, 2023) Hadero Medalcho, Tadewos; Abegaz, Kebede; Dessalegn, Engeda; Maté Caballero, Juan Ignacio; Agronomía, Biotecnología y Alimentación; Agronomia, Bioteknologia eta Elikadura
    The uses of natural plant origin bioactive compounds are emerging as a promising strategy to detoxify aflatoxin B1 (AFB1). This study aimed to explore the potential of cooking, phytochemicals content, and antioxidant activities derived from garlic, ginger, cardamom, and black cumin to detoxify AFB1 on spice mix red pepper powder (berbere) and sauté. The effectiveness of the samples was analyzed for AFB1 detoxification potential through standard methods for the examination of food and food additives. These major spices showed an AFB1 level below the detection limit. After cooking in hot water for 7 min at 85 ¿, the experimental and commercial spice mix red pepper showed the maximum AFB1 detoxification (62.13% and 65.95%, respectively). Thus, mixing major spices to produce a spice mix red pepper powder had a positive effect on AFB1 detoxification in raw and cooked spice mix red pepper samples. Total phenolic content, total flavonoid content, 2,2-diphenyl-1-picrylhydrazyl, ferric ion reducing antioxidant power, and ferrous ion chelating activity revealed good positive correlation with AFB1 detoxification at p < 0.05. The findings of this study could contribute to mitigation plans of AFB1 in spice-processing enterprises. Further study is required on the mechanism of AFB1 detoxification and safety of the detoxified products.

    Physical, chemical and microbiological changes in liquid micellar casein concentrates induced by high-pressure treatments
    (Elseiver, 2022) García Amezketa, Arantza; Iturmendi Vizcay, Nerea; Galarza Iriarte, Uxue; Maté Caballero, Juan Ignacio; Fernández García, Teresa; Agronomía, Biotecnología y Alimentación; Agronomia, Bioteknologia eta Elikadura; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
    Microfiltration and diafiltration were conducted to obtain 3 distinct levels of liquid micellar casein concentrates from raw skim milk: 8, 10 and 11.5 g casein/100 g. All the concentrates were subjected to 300, 450 and 600 MPa for 5 min. The physicochemical and microbiological changes in the matrix were studied and compared with their untreated counterparts on the day of production and after storing the samples for 7 d at 10 °C. Slight changes in pH were correlated with pressurization; the higher the pressure the greater the decrease in pH. For the least concentrated sample, changes were more noticeable. Furthermore, changes in particle size mainly occurred as a consequence of pressurization but also depended on casein concentration: aggregation and disruption phenomena were observed in the most concentrated samples. In terms of microbial quality, 600 MPa was the only treatment capable of achieving effective microbial control.
