Facing the need of a company that sells mango as raw material for processing as puree, nectar or juice, researchers at the University of Guanajuato (UGTO), in the center of Mexico, designed a prototype pasteurization machine for the product and a procedures manual to keep it in excellent condition after harvest.

Thanks to the Innovation Research Program of High Added Value (Innovapyme) of the National Council of Science and Technology (Conacyt), the product was studied for a year to learn how to keep it in optimal condition, explains Maria Del Rosario Abraham Juarez, from the Department of Food Division of the Life Sciences Campus of the University of Guanajuato.

"The company had the need to know the quality characteristics of mango pulp for exportation. At the UGTO we performed two parts of the project: delivered and trained people with a user's postharvest manual for hardling raw material of the company, which produces five varieties of the fruit, as well as designing a prototype of a pasteurization machine."

The company sells the fruit as raw material to customers who process the product to make puree, mango nectar or juice. Therefore, the research team designed the pasteurizer, which system preserves food, removing pathogens that could harm consumers.

It also prevents oxidation of the mango pulp, as well as a dark color of the pulp; being one of the objectives of pasteurization. The technology conducted by researchers at the UGTO is pasteurizing mango varieties and maintain their organoleptic pulp, which maintains its physical characteristic and is dehydrated without losing its flavor, color and nutrition.

"We work with five species of mango and talk about a technology that pasteurizes industrial tons of fruit. We verify its operation so that the fruit pulp maintains the characteristics of fresh mango," said the specialist UGTO.

According to the researcher, the company was satisfied with the technology and manual used for the five varieties of the fruit. And Abraham Juarez recognizes that the most difficult task was to manage the fiber of the fruit, so they learned to maintain a certain temperature and its overall features.

"Both the manual and technology were designed specifically for the mango industry, because we did a tailored suit for the company that requested it. And if a company is engaged in processing strawberries, technology should be designed specifically for them," concludes PhD Abraham Juarez. (Agencia ID)
