Flash vacuum expansion: an alternative with potential for Ataulfo and Manila mango processing.

Mangoes of the Manila and Ataulfo varieties are characterized by having a pleasant flavor and an attractive color of both the peel and pulp. However, due to their post-harvest physiology, they are highly perishable and very susceptible to physical damage, which greatly limits marketing these fruits. Therefore, it is necessary to evaluate technologies that preserve their organoleptic and nutritional properties.

Comparison of the Effect of Hydrostatic and Dynamic High Pressure Processing on the Enzymatic Activity and Physicochemical Quality Attributes of 'Ataulfo' Mango Nectar.

The effects of hydrostatic (HHP) and dynamic (HPH) high-pressure treatments on the activity of pectin methylesterase (PME) and polyphenol oxidase (PPO) as well as the physicochemical quality attributes of 'Ataulfo' mango nectar were assessed. HHP reduced PME relative activity by 28% at 100 MPa for 5 min but increased PPO activity almost five-fold. Contrarily, HPH did not affect PME activity, but PPO was effectively reduced to 10% of residual activity at 300 MPa and at three passes.

Human Health Risk Associated with the Consumption of Aflatoxins in Popcorn.

Introduction: Aflatoxins are secondary metabolites produced mainly by the molds and , and they contaminate cereals, dry fruits, oilseeds and spices. Aflatoxins have harmful effects in animals and humans, inducing vomiting, diarrhea, hepatitis, cirrhosis, immunosuppression, miscarriages, mutagenic and teratogenic effects, resulting in different cancers. Popcorn ( everta) is a cereal susceptible to aflatoxin contamination, and there are no reports about the risk of its consumption.

Flash Vacuum-Expansion Process: Effect on the Sensory, Color and Texture Attributes of Avocado (Persea americana) Puree.

The flash vacuum-expansion process (FVE) consists of two stages. In the first, the raw material is heated by a steam flow in a chamber at 101.325 kPa; in the second, the plant material passes into an expansion chamber (2 to 5 kPa), where the disintegration of the tissues occur.

Presence of unreported carcinogens, Aflatoxins and their hydroxylated metabolites, in industrialized Oaxaca cheese from Mexico City.

Aflatoxins (AFs) are toxic secondary metabolites of the fungi Aspergillus flavus, A. parasiticus and A. nomius.

Assessment of Aflatoxin M1 and M2 exposure risk through Oaxaca cheese consumption in southeastern Mexico.

The present study evaluated the exposure of Southeast Mexican population to Aflatoxin M1 (AFM1) and M2 (AFM2) through the consumption of Oaxaca cheese. The intake of Oaxaca cheese was assessed via a food 7-day dairy questionnaire (N = 1100, 2014 and 2015). Thirty Oaxaca cheeses were randomly sampled, and the origin of the samples was also investigated.

Resistance of Mexican fruit fly to quarantine treatments of high-pressure processing combined with cold.

Mexican fruit fly Anastrepha ludens Loew (Diptera: Tephritidae) is one of the most important insects infesting fruits. Although high pressure has been proposed as an alternative quarantine process for this pest, conditions applied to destroy eggs and larvae can also damage the fruits. The objective of this study was to assess the biological viability of A.
