CA storage helps to maintain cherry tomato fruit quality

The objective of this study was to analyze changes the chemical composition of ?cherry? tomato (Solanum lycopersicum L. var. cerasiforme) fruit during storage under controlled atmosphere. The experiment was conducted in 2013. The plants of one ?cherry? tomato cultivar ? ?Pareso F1? were grown in mineral wool slabs. Fruits were harvested in September at the pink stage of maturity (3rd, USDA standard chart). One part was stored under controlled atmosphere (CA: 3% CO2 and 3% O2), second under ultra-low oxygen (ULO: 3% CO2 and 1.5% O2) and third was under normal atmosphere (NA). Fruits from every combination were stored for two, three and four weeks at 12 ?C. The storage conditions and length of storage time affected the results (e.g. dry matter, total sugars content, pH of juice). Chemical analyses were carried out before and after storage. Following properties were measured: dry matter, total sugars content, pH of juice, titratable acidity and soluble solids content. The results showed that the dry matter content of fruits stored under normal atmosphere changed the most in comparison to another combination. Total sugars content was lower decrease during storage in every combination and after four weeks was the lowest. The storage under using atmosphere caused higher pH of juice and the highest level of pH was observed after four weeks of storage. In every combination the total soluble solids content decrease during storage period and in case of fruits stored under normal atmosphere was the lowest. ?
