    AbstractThe oxidative and physical stability of the reformulated mayonnaise with processed beetroot was investigated and compared with a control (mayonnaise without beetroot) and a commercially available product. Processing of beetroot had an impact on the structural integrity of the antioxidants present. Microwaving (960W for 7min) was advantageous for preserving the betalain and polyphenol content of beetroot compared to roasting (180°C for 90min) and boiling (100°C for 30min). The oxidative stability of mayonnaise samples was determined by Rancimat and the thiobarbituric (TBA) assay. The addition of microwaved beetroot significantly enhanced the oxidative stability of mayonnaise at the end of a storage period of 4 weeks (4°C). Although no significant differences (p>0.05) were detected between the mayonnaise samples containing beetroot and the commercial control, the latter was less susceptible to oxidation during storage. The turbiscan stability index (TSI) revealed that the commercial mayonnaise was less prone to destabilization phenomena. All the textural parameters increased with the incorporation of beetroot. The sensory evaluation revealed that, with the exception of graininess and uniformity, most of the sensory attributes are preserved if not improved with the addition of beetroot

    Objective: the objective of this research work was to obtain the varietal description of two varieties of chile manzano in Las Montañas in the center of Veracruz, México. Design/methodology/approach: the varietal characterization module was established under greenhouse conditions at the Centro de Bachillerato Tecnológico Agropecuario No. 99 in the municipality of Coscomatepec de Bravo. The recorded descriptors were in accordance with the International of Plant Genetic Resources Institute for Capsicum and the Graphic Handbook for Variety Description of manzano hot pepper. The plants were characterized from the seedling to the adult plant. The agronomic management of the crop was carried out in accordance with the manual for the production of manzano hot pepper in Las Montañas of the state of Veracruz. Results: all qualitative descriptors were constant for the two varieties MEXUVNE1-15-C2 and MEXUVCU1-16-C2 from seedling to fruiting; in contrast, there were dissimilarities in plant height, stem, leaf, flower, fruit and seed dimensions. Limitations of the study/implications: the pandemic caused by COVID-19 was the main limitation so that some descriptors were not recorded in a timely manner as indicated in the Graphic Handbook. Findings/conclusions: both varieties are very similar; however, the greatest distinction was in the quantitative type descriptors such as: plant height, fruit length, fruit diameter and number of seeds.Objective: The objective of this research study was to obtain the varietal description of two varieties of manzano chili pepper in Las Montañas region, in central Veracruz, Mexico. Design/methodology/approach: The varietal characterization module was established under greenhouse conditions. The markers recorded were in accordance with the International Plant Genetic Resources Institute for Capsicum and the Graphic Handbook for Variety Description of manzano chili pepper. The plants were characterized from seedling in greenhouse to adult plant. The agronomic management of the crop was carried out in accordance with the manual for the production of manzano chili pepper in Las Montañas, state of Veracruz. Results: All qualitative markers were constant for the two varieties, MEXUVNE1-15-C2 and MEXUVCU1-16-C2, from seedling to fruit setting. In contrast, there were dissimilarities in plant height, and stem, leaf, flower, fruit and seed dimensions. Study limitations/implications: The pandemic caused by COVID-19 was the main limitation, resulting in some markers not being recorded in a timely manner as indicated in the Graphic Handbook. Findings/conclusions: Both varieties are very similar; however, the greatest distinction was in the quantitative markers, such as: plant height, fruit length, fruit diameter and number of seeds
