The treatments of chemicals and packaging methods were arranged in a split split plot design with four replications.
To determine the effectiveness of chemicals, dehanding methods, storage temperature, and packaging material on the control of browning of banana crown. Arteaga G, Diana M. The results showed that the best pqrdeamiento in reducing browning was thiourea and aluminum potassium sulfate, because they were sulfur-containing compunds, which were reported to reduce browing.
Control of crown browning in banana (Musa sp.)
The results showed that temperature had significant effects on browning of banana crown. Then, the content of phenols and their antioxidant capacity are analyzed by the use of the Oxygen Radical Absorbance Capacity —ORAC— method in order to, finally, study their application on apples and bananas as reference fruits that suffer from enzymatic browning, by analyzing the browning rates and the change of the normal color.
The objective was to evaluate the antioxidant capacity of carob Hymenaea courbaril Linneaus on fruits susceptible to enzymatic browning. University of Gezira, Wad Medani Sudan.
Dehanding by separation under water, dehanding by separation in air, and cutting by knife under water were similar and better than cutting by knife in air which gave the worst results due to the availability of oxygen and abundant phenolic compounds as a result of cutting.
The dehanding method treatments were arranged in a split plot design with four replications.
Keeping in mind the inerest of contributing to the solution of the commercialization of healthy and minimally transformed fruits, this research work appears to study the anioxidant properties of the peel, the seed and the pulp of the carob and its application on fruits susceptible to such reactions, as the third phase of a research pardeamuento about the obtainment of natural conservants from this native plant.
On the other hand, there is a constant deterioration suffered by fresh fruits and vegetables due to changes, reactions or decomposition that degrade their color, texture and taste. This is due to low oxygen concentration inside the package.
A new source of antioxidants to control enzymatic browning: Fresh fruits and vegetables have had an increase of their demand during the last decade, because there is evidence of the correlation bewteen their consumption and lower risks of chronic and degenerative diseases.
Control of crown browning in banana Musa sp. Dehanding enaimatico were dehanding by separation under water, dehanding by separation in air, cutting by knife under water, and cutting by knife in air.

Lookup the document at: The use of intact polyethylene bags was the best method of packaging in reducing banana crown browning compared with perforated and no pardemaiento.
Journal of Engineering and Technology;Vol. The study, particularly, starts with a physical-chemical characterization of the peel, the seed and the pulp of the carob.
