VANOYE-ELIGIO, Maximiliano; LOPEZ-GARCIA, Leydi Leticia; GARCIA-VELA, José Alfredo  e  ALAVEZ-GONGORA, José Alberto. Use of the melina fruit (Gmelina arboreal Roxb) as an antimicrobial and natural colorant. Agron. Costarricense [online]. 2020, vol.44, n.1, pp.105-112. ISSN 0377-9424.  http://dx.doi.org/10.15517/rac.v44i1.40007.

The melina is a forest species of Asian origin, is characterized by rapid growth. This species has been successful in the Mexican southeast. The most common uses that are given to this species are for the production of furniture, structural construction, light work, carpentry and joinery, however, currently the melina fruit has not been used in industry, therefore, the objective of this work was the integral use of the melina for use in the food industry as an antimicrobial agent, and its use as a natural colorant for the textile industry. This was achieved through an experimental design for antimicrobial evaluation and its use as a dye. The results indicated that there was not significant difference (p<0.05) between treatments to determine antimicrobial capacity. In relation to its use in the textile industry, it was detected that vinegar mordant in the different states of ripeness of the fruit and in the rind had a greater coloration and uniformity when dyeing the fabrics, being the blanket fabric where better results existed. Therefore, it is important to consider the melina as a species with timber and non-timber purposes.
