摘要

研究了鳄梨种子(Persea americana Mill cv.)不同极性提取物的抗氧化、抗菌和体外着色能力。罗瑞拉)。此外，采用索氏法从美洲鳄梨(P. americana Mill Hass)栽培品种的残中果皮中提取鳄梨油，并对提取油的理化性质和脂肪酸组成进行了评价。着色剂和鳄梨油都被用作液体肥皂型配方的原料。用DPPH法测定着色剂提取物的抗氧化活性，其中水提取物的抗氧化活性最高。对金黄色葡萄球菌ATCC 29213和大肠杆菌ATCC 25922均无抑菌活性。碘值(177.52 cg I2 g-1)表明所得牛油果油具有较高的不饱和程度，皂化指数为190.74 mg KOH g-1。用NaOH (L*=0.15, a*=0.05, b*=-0.44)提取的着色剂在pH为6.2的液体皂基质中保存1个月完全稳定。这一分析表明，它在肥皂和化妆品行业有很高的机会。

Evaluation of a colorant and oil extracted from avocado waste as functional components of a liquid soap formulation

The present research evaluated the antioxidant, antimicrobial and in vitro coloring capacity of extracts with different polarity obtained from avocado seeds (Persea americana Mill cv. Lorena). Besides, avocado oil was extracted from the residual mesocarps of P. americana Mill Hass cultivar by Soxhlet methodology, and the physicochemical properties of the extracted oil, as well as its fatty acid composition, were evaluated. Both the colorant and the avocado oil were used as supplies for a liquid soap type formulation. The antioxidant activity of the colorant extracts was determined by DPPH whereby water extracts showed the highest activity among the treatments. None of the extracts showed antimicrobial activity against Staphylococcus aureus ATCC 29213 and Escherichia coli ATCC 25922. The iodine value (177.52 cg I2 g-1) indicated that the avocado oil obtained has a high degree of unsaturation, and the Saponification index had a value of 190.74 mg KOH g-1. The colorant extracted with NaOH (L*=0.15, a*=0.05, and b*=-0.44) from the seeds was completely stable in a liquid soap matrix at pH 6.2 during one month of storage. This analysis suggests that it has high opportunities in the soap and cosmetic industry.

期刊介绍： La Revista Facultad Nacional de Agronomía Medellín (RFNA), de la Universidad Nacional de Colombia, Sede Medellín, Facultad de Ciencias Agrarias, es una publicación científica editada desde el año 1939, en formato impreso y digital y de acceso abierto desde la web —sin costo para autores y lectores—. Está orientada a investigadores que crean conocimiento disciplinar y multidisciplinar que articula la ciencia y la tecnología para hacer más productivo el campo a nivel empresarial y de economía campesina. La Revista tiene como objetivo divulgar resultados de investigación mediante artículos originales, inéditos y arbitrados (peer review) de carácter científico que respondan a preguntas específicas y que proporcionen sustento y pruebas a una hipótesis, en aspectos relacionados con las Ciencias Agronómicas, Producción animal, Ciencias Forestales, Ingeniería Agrícola, de Alimentos y otras afines que contribuyan a la solución de los limitantes del agro a nivel nacional, regional e internacional. La Revista recibe y publica, sin ningún costo, artículos en idioma inglés de investigación, revisión, reseñas y cartas al editor. Desde el 2017 la periodicidad de publicación es cuatrimestral, se publican tres números al año con circulación nacional e internacional, en los siguientes períodos: Enero - Abril Mayo - Agosto Septiembre - Diciembre This journal does not charge APCs or submission charges.
