Se ha determinado la concentración de aflatoxina total y ocratoxina A en la maca seca y harina de maca (Lepidium meyenii walp), así como los factores fisicoquímicos y microbiológicos que influyen en su producción. Para ello se ha recolectado muestras de 4 comunidades productoras y de 4 mercados principales. Los factores extrínsecos como temperatura y humedad relativa promedio son 10oC y 52,5% en las comunidades y 15oC y 71% en los mercados, estas condiciones hacen posible el crecimiento y desarrollo de Fusarium avenaceum, Penicillium corylophylum, P.commune, P.chrysogenum, Aspergilus níger, A.flavus, A.ochraceus, esclerotia de A.flavus, Rizophus y levaduras. Se ha determinado la concentración promedio de aflatoxina total 0,8295 ppb (µg/Kg), cifra que indica buena calidad de maca seca y la concentración promedio de ocratoxina A 8,703 ppb, cifra que sobrepasa el límite máximo p...

Maca is nutritious, energetic and functional food. As a defense mechanism, its secondary metabolites react to biotic and abiotic stress, during pre-harvest, harvest and traditional post-harvest drying. The aim of this review is to evaluate and provide relevant scientific information about bioactives, biochemistry and biological activity of the maca (Lepidium meyenii Walpers or Lepidium peruvianum Chacón) related to health and reassess its functional food condition. A search of four electronic databases and information required from the authors was used for this review. There is a lack of in vivo and clinical research with more representative sample sizes and more consistent methodologies. Therefore, glucosinolates, phenolic compounds, phytosterols, macaenes, macamides, macahidantoins, meyeniins, alkaloids and others formed during the productive cycle of maca act synergistically to preve...

The objective of this study was to determine the chemical composition, glucosinolate content and biological value of extruded black maca flour and its mixture with oats. The black maca was collected, subjected to dehydration, extruded and grinding, obtaining extruded flour and then analyzed, then it was mixed with precooked oats in three different ratios (w / w), oats: extruded black maca flour (80:20; 85:15 and 90:10). The results of the chemical composition of the extruded black maca flour were protein 11.62% and ash 4.28%, highlighting its iron content 30.71mg / 100g and essential amino acids such as lysine, valine, threonine, leucine, isoleucine and arginine. The total glucosinolate content of extruded maca flour was 7.93 ± 0.17 μmol / g (b.s). The sensory evaluation of the mixture showed a significant difference between mixtures, the ratio 20:80 being the most sensory acceptable. ...
