Las micotoxinas: un problema que resurge con fuerza
(Interempresas, 2015-10-01)Las micotoxinas son metabolitos fúngicos tóxicos frecuentes en alimentos y piensos. Suponen un riesgo para la Salud Pública al poder producir, entre otros, efectos cancerígenos, teratogénicos, embriotóxicos, hepatotóxicos, ... -
Lipase activity and enantioselectivity of whole cells from a wild-type Aspergillius flavus strain
(Elsevier, 2014)This study reports the high enantiomeric preference of whole cell lipase from Aspergillus flavus wild-type that allows the preparation of a chiral secondary alcohol. Whole cells prepared from a wild-type Aspergillus flavus ... -
Lipoxygenase activity is involved in the regeneration of volatile ester-synthesizing capacity after ultra-low oxygen storage of 'Fuji' apple.
(American Chemical Society, 2009)An extra period under cold air after ultra-low oxygen storage has been shown to increase the concentration of some volatile compounds emitted by stored 'Fuji' apples. The purpose of this work was to assess the role, if ... -
Long-term storage of Pink Lady apples modifies volatile-involved enzyme activities: consequences on production of volatile esters
(American Chemical Society, 2008)Pink Lady apples were harvested at commercial maturity and stored at 1 °C and 92% relative humidity under either air or controlled atmosphere conditions (2 kPa O2:2 kPa CO2 and 1 kPa O2:1 kPa CO2) for 27 weeks. Data on ... -
Low doses of ochratoxin A induce micronucleus formation and delay DNA repair in human lymphocytes
(Elsevier, 2014-12)The contamination of food commodities by fungal toxins has attracted great interest because many of these mycotoxins are responsible for different diseases, including cancer and other chronic illnesses. Ochratoxin A (OTA) ... -
Mechanisms of resistance in postharvest fruit-pathogen interaction
(Universidad Autónoma Chapingo, 2015)The objective of this review was to bring together concepts related to studies aimed at elucidating defense mechanisms against disease-causing agents, mainly in postharvest. Like plants, fruits are exposed to attack by ... -
Metabolic and Microbial Modulation of the Large Intestine Ecosystem by Non-Absorbed Diet Phenolic Compounds: A Review
(MDPI, 2015)Phenolic compounds represent a diverse group of phytochemicals whose intake is associated with a wide spectrum of health benefits. As consequence of their low bioavailability, most of them reach the large intestine where, ... -
Metabolite profiling of olive oil and thyme phenols after a sustained intake of two phenol-enriched olive oils by humans: Identification of compliance markers
(Elsevier, 2014)An understanding of causal relations between phenol intake and its beneficial effects on health is hindered by the lack of robust biological markers of its exposure. This is particularly relevant in mid/long-term nutritional ... -
Micotoxinas en alimentación animal: ¿es posible reducir su efecto mediante la adición de adsorbentes a los piensos?
(Asís Veterinaria, 2019-05-01) -
Microencapsulation of cinnamon leaf (Cinnamomum zeylanicum) and garlic (Allium sativum) oils in beta-cyclodextrin
(Springer, 2008-04)Cinnamon leaf (CLO) and garlic oils (GO) are good antimicrobials, however, their volatility complicates their application as food preservatives. Hence, microencapsulation of CLO and GO with beta-cyclodextrin (beta-CD) was ... -
Mode of action of a fatty acid-based natural product to control Botrytis cinerea in grapes
(The Society for Applied Microbiology, 2014)Aims: To investigate the efficacy and mode of action of the fatty acid-based product Foodcoat((R)) (FC) against Botrytis cinerea. Methods and Results: In vitro, in vivo and field experiments were carried out to investigate ... -
Modeling kinetics of aflatoxin production by Aspergillus flavus in maize-based medium and maize grain
(Elsevier, 2013)Predictive mycology has dealt mainly with germination, growth and inactivation of fungi while the issue of mycotoxin production remains relatively unexplored. Very few studies provide biomass dry weight/colony size data ... -
Modeling postharvest mycotoxins in foods: recent research
(Elsevier, 2016)Available information on the prediction of postharvest production of mycotoxins in recent years is reviewed. Predictive mycology has been focused mainly on fungal growth whereas studies on prediction of mycotoxins in foods ... -
