(2016-06)The objective of this work was to assess the possibility of obtaining calcium-added soymilk with acceptable characteristics regarding protein solubility and physical stability, and inactivation of trypsin inhibitors and ... -
Comparison of different analytical methods to evaluate the heat shock protein (HSP) response in fruits. Application to tomatoes subjected to stress treatments
(Elsevier, 2020-09-23)Heat shock proteins (HSP) are synthesized in living tissues exposed to transient increase in temperature and play a central role in the protective response against heat and other stresses. In fruits, this response to heat ... -
Desarrollo de cultivos probióticos deshidratados por secado spray para la aplicación en alimentos. Estudios microbiológicos y tecnológicos
(Facultad de Ciencias Exactas, Universidad Nacional de La Plata, 2013)El mercado de alimentos funcionales, en particular aquellos que incorporan bacterias probióticas, se encuentra en constante expansión. La diversificación del mercado de bacterias probióticas genera la necesidad de disponer ... -
Effect of heat treatment and spray drying on lactobacilli viability and resistance to simulated gastrointestinal digestion
(Elsevier, 2012-10)Commercial probiotic bacteria are delivered mainly as frozen or freeze-dried cultures. However, spray drying is a lower cost technology that could be used for the production of probiotic cultures. In this work we aimed at ... -
Evaluación del efecto de los tratamientos de estrés térmicos aplicados en frutos cítricos para reducir daño por frío. Acumulación de proteínas de estr
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2007)Due to successful application of thermal treatments to prevent the development of CI in fruits and vegetables, the purpose of the present thesis was to characterize the effect of these treatments on the physiological and ... -
Evaluation of Biochemical and Quality Attributes to Monitor the Application of Heat and Cold Treatments in Tomato Fruit (Lycopersicon Esculentum Mill.)
(2015-06)The study was accomplished to optimize the application of stress treatment to prevent chilling injury (CI) in tomatoes. Four treatments were evaluated: control, heat shock applied for 24 (HS24) and 48 h (HS48), and cold ... -
Heat treatment conditioning differentially affects the fruit quality and the carbohydrate metabolism during postharvest cold storage of two tangor (Citrus reticulata Blanco) cultivars: ‘Murcott’ and ‘W-Murcott’
(Elsevier, 2024-04)Citrus is highly susceptible to damage from cold temperatures, and conditioning procedures are commonly used to protect the fruit, and maintain its sensory qualities and external appearance. This study investigates the ... -
Immediate- and long-term proteomic responses of epicarp from two heat conditioned tangor cultivars stored at low temperature differing in their susceptibility to infection
(Elsevier, 2020-03)Citrus is one of the most relevant horticultural crops worldwide. Among them, tangors are highly appreciated by their distinctively taste and aroma. However, both mandarins and tangors are especially susceptible to cold ... -
Influence of chymosin type and curd scalding temperature on proteolysis of hard cooked cheeses
(Cambridge University Press, 2015-08)In this work, we studied the influence of the type of coagulant enzyme and the curd scalding temperature on the proteolysis and residual coagulant and plasmin activities of a cooked cheese, Reggianito, in the interest of ... -
Metabolic profiling and quality assessment during the postharvest of two tangor varieties subjected to heat treatments
(2018)Citrus growth and export are one of the most important agroeconomical activities in regions with Mediterranean-like climates. Among them, tangors in particular are appreciated by their sweet taste and delicate palatability. ... -
