Analysis of Apple Candying by Microwave Spectroscopy

Tomas-Egea, Juan A.; Fito, Pedro J.; Castro Giraldez, Marta (MDPI AG, 2019-08-04)

[EN] Process control in the industry requires fast, safe and easily applicable methods. In this sense, the use of dielectric spectroscopy in the microwave range can be a great opportunity to monitor processes in which the ...
Caracterización de las propiedades físicas de polvos de cacao sometidos a diferentes niveles de alcalinización

Martínez Fernández, Rocío (Universitat Politècnica de València, 2016-10-13)

[ES] Durante la elaboración de productos a partir de cacao en polvo, propiedades físicas como el color, tamaño de partícula, densidad, humectabilidad afectan a parámetros tan importantes como son la reología, la textura ...
Determinación experimental y modelización de las isotermas de sorción de hígado de cerdo

Hernández Zahonero, Adrián (Universitat Politècnica de València, 2019-10-02)

[ES] Las isotermas de sorción son necesarias en procesos de secado y almacenamiento de alimentos ya que nos permiten conocer la relación en el equilibrio entre actividad de agua y humedad del producto. No existen datos ...
Fotónica aplicada a la monitorización de procesos y al desarrollo de sensores en la industria agroalimentaria

Tomás Egea, Juan Ángel (Universitat Politècnica de València, 2022-04-29)

[ES] El objetivo de la presente tesis es el de desarrollar y utilizar técnicas basadas en la fotónica de baja frecuencia, como la radiofrecuencia, las microondas y los infrarrojos, para monitorizar de forma no destructiva ...
Fuel concentration in isothermal Diesel sprays through structured planar laser imaging measurements

Payri, Raul; Gimeno, Jaime; Marti-Aldaravi, Pedro; Manin, J. (ELSEVIER SCIENCE INC, 2012)

[EN] The mixing of isothermal liquid sprays in engine-like conditions has been investigated by applying the structured planar laser imaging technique to remove multiple light scattering. The intensity of the illumination ...
Mathematical relationship between glass transition temperature and water activity of cellular and non-cellular food systems

Nguyen, Thanh; khalloufi, Seddik; Ratti, Cristina (Editorial Universitat Politècnica de València, 2018-09-07)

[EN] Cellular and non-cellular-solid food systems were used to obtain experimental data of aw and Tg as a function of moisture content during drying. GAB, Gordon-Taylor, and Khalloufi-Ratti models were used to obtain the ...
Phase transitions in starch based films containing fatty acids. Effect on water sorption and mechanical behaviour

Jiménez Marco, Alberto; Fabra Rovira, María José; Talens Oliag, Pau; Chiralt Boix, Mª Amparo (Elsevier, 2013-01)

The water sorption capacity (WSC) of starch films containing, or not, glycerol (1:0.25 starch:glycerol ratio) and fatty (palmitic, stearic and oleic) acids (1:0.15 starch:fatty acid ratio) was analysed at 10, 25 and 40 ...
Physicochemical characterization of mesquite flours

Sandoval Torres, S.; Reyes López, L.; Méndez Lagunas, L.; Rodríguez Ramírez, J.; Barriada Bernal, G. (Editorial Universitat Politècnica de València, 2018-09-07)

[EN] Ethnic foods are healthy products interesting for the new societies. Mesquite flour offers another option for making gluten-free recipes as part of a diet for people with celiac disease. The physicochemical properties ...
Propiedades de films de almidón de maíz. Influencia de la incorporación de lípidos, biopolímeros y compuestos bioactivos

Jiménez Marco, Alberto (Universitat Politècnica de València, 2013-04-25)

Abstract Biodegradable starch-glycerol based films were obtained. The influence of lipid compounds (palmitic, stearic and oleic acid), other polymers (hydroxypropylmethylcellulose and sodium caseinate) and bioactive ...
Study of the effect of microwave power coupled with hot air drying on orange peel by dielectric spectroscopy

Talens Vila, Clara; Castro Giraldez, Marta; Fito Suñer, Pedro José (Elsevier, 2016-03)

[EN] Monitoring moisture and water activity during drying is crucial for process optimization, avoiding inadequate uses of energy. The main objective of this work was to study the dielectric properties of orange peel during ...
