Physicochemical characterization of pectin and mango peel ( L.) from Mexican cultivars.

In Mexico, about 40 % of the mango harvest is lost due to marketing problems. Moreover, the mango industry generates peel and seed waste that ranges from 35 to 60 % of the total weight of processed fruits. This unexploited mango biomass represents a potential resource for producing value-added by-products.

Glucanases and Chitinases in : Identification, Classification, Phylogeny, and Expression Analysis of Defense Genes against spp.

Plant glucanases and chitinases are defense proteins that participate in pathogenesis; however, very little is known about the glucanase () and chitinase () gene families in mango. Some mango cultivars are of great economic importance and can be affected by anthracnose, a postharvest disease caused by fungi of the genus spp. This study identified and characterized 23 putative glucanases and 16 chitinases in the mango genome cv.

Agronomic Behavior of Mexican Roselle Cultivars Produced under Protected Agricultural Conditions.

Growth dynamics and morphological traits are used to define the characteristics of roselle cultivars . The morpho-agronomic variability of plants was evaluated, as well as the concentration of macro and micronutrients in leaves of Mexican roselle cultivars in hydroponic and greenhouse conditions. The following roselle cultivars were studied: 'Cruza Negra', 'UAN16-2', 'Criolla Huajicori', 'UAN 6 Puga', 'UAN 25-1' and '4Q4'.

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.
