Efecto de la conservación por frío sobre la vida útil del mango y durazno

Abstract

Cold storage of fruits in their natural state involves various structural, biochemical and compositional changes that are specific to each type of fruit. The objective of this descriptive research work is to determine the effect of cold storage on the shelf life of mango and peach to maintain nutritional and sensory quality, through a literature review. Information was collected from several articles from scientific bases of the last 5 years. Comparing various methods of cold storage of mango and peach, it was evidenced according to the data presented by several researchers that the parameters of temperature and relative humidity inside cold chambers are similar for both fruits due to the fact that the two species of fruits are climacteric, being This is a favorable factor in terms of control of physiological and organoleptic maturity within the cold chamber. It is concluded through the bibliographic review that the best cold storage conditions for mango and peach in their natural state is a temperature of 0°C, a relative humidity of 85% and a controlled atmosphere with the application of 2% O2, 5 % of CO2- and 90% of N2, conditions that must be applied in the cold chamber. The cold room should be divided into two sections, one for the mango and one for the peach; with capacity for 36 pallets with 14 levels (beds or floors) each, in which 9 cardboard boxes for fruit enter, therefore, 126 boxes per pallet.
