“…The value indicated by the device represents the maximum stress expressed in Newton (N) required for the pulp to be penetrated by the tip of the penetrometer; that value represents the firmness of the fruit (Tano et al 2007). …”

Fruit ripening is associated with many hydrolase activities involved in the softening of the fruit during the maturation. This study investigates the relationship between the loss of firmness along with the changes of sugar content and the enzymatic activities in Carica papaya L.var solo 8 during post-harvest storage. Three maturation stages (green immature: the fruit is entirely green, green mature: the fruit shows 1/32 yellow skin and fully mature: the fruit shows 1/8 yellow skin) have been selected and stored at 15, 22 and 28°C. The reduction of fruit firmness, total sugar contents, refractive index (% Brix) and enzymatic activities were measured. Low enzymatic activities (0.035 μmol/min/mg) were recorded in fruit harvested at the green immature stage with no significant (p≥0.05) effect on the softening while fruit harvested at the green mature and fully mature stages showed enzymatic activities 7 times as high as those of the green immature stage. These high enzymatic activities were responsible for the loss of firmness of the fruit. Accordingly, papayas at the green mature and fully mature stages displayed higher maxima of sugar content (4.8 g/100 g at 28°C at day 12, and 10.2 g/100 g at 22°C at day 8, respectively) at higher temperatures. Meanwhile in green immature papayas, the maximum was only 4.3 g/100 g at 22°C and day 12 of storage. The results show that the loss of firmness of the papaya was highly related to the hydrolytic enzyme activities and the sweet taste to the presence of simple sugars such as galactose liberated from the polysaccharide complexes.

“…In addition, responses of apple fruit to storage conditions are very specific and vary depending on many factors, such as pre-harvest climatic conditions (air temperature, relative humidity, amount of precipitations), genotype differences, maturity stage at-harvest (Drudze, 2003;2005). According to literature, low temperature is the most important factor in maintaining quality and extending the cold storage and shelf-life of fruits and vegetables after harvest (Tano et al, 2007). However, environmental conditions such as gas composition in storage rooms also play a crucial role.…”

In this study, we evaluated the influence of 1-methylcyclopropene (1-MCP) treatment and ultra-low oxygen (ULO)-controlled atmosphere conditions: 2.0% CO 2 and 1.0% O 2 (ULO1), and 2.5% CO 2 and 1.5% O 2 (ULO2) on the changes in chemical composition in the apples of one of the commercially available and the most consumerpreferred cultivar 'Auksis' during long-term storage. This study was conducted from 2012 to 2014 at the Institute of Horticulture, Latvia University of Agriculture in Dobele. The results of the current research evidence that in many cases the chemical composition of 'Auksis' apples depends on the weather conditions (growing season) and storage technology. In terms of storage technology, a better preservation of soluble solids was achieved when ULO conditions and 1-MCP treatment were applied. Moreover, findings reveal that polyphenols present in 'Auksis' apples remained unchanged after six months' storage under ULO conditions. While due to further ripening process in control and 1-MCP treated apples the content of polyphenols increased. The harvest time is the key factor influencing the total pectin content, while, during six months' storage the main factors affecting the content of pectin were the growing season and storage technology. Analysis of variance showed that the content of vitamin C in 'Auksis' apples depended mainly on the weather conditions, whereas post-harvest vitamin C losses are affected by harvesting time and storage technology.

“…Low temperature is the most important factor in maintaining quality and extending the shelf-life of fruits and vegetables after harvest. Most of the physiological, biochemical and microbiological activities contributing to the deterioration of produce quality are largely dependent on temperature (Tano et al 2007). However, gas composition of the ambient air also plays an important role.…”

Tomato quality in controlled atmosphere storage, modified atmosphere packaging and cold storage

Effects of controlled atmosphere storage (CAS) and modified atmosphere packaging (MAP) in comparison with conventional cold storage on qualitative properties of green-mature harvested tomato were evaluated. Qualitative properties included firmness, redness value (a*), hue angle, Total Soluble Solids (TSS) content, Titratable Acidity (TA) and TSS/TA. Under CAS and MAP conditions, gas composition was 5 kPa O 2 and 3 kPa CO 2 . Results showed that the ability of CAS and MAP to retard the ripening process was more than cold storage. With regard to maintaining texture and colour, CAS treatment was the best and MAP was better than cold storage. Although amongst storage treatments, the maximum value of TSS was observed in cold storage, its decreasing trend in CAS was slower than that in cold storage. Additionally, MAP and especially CAS slowed down the diminishing trend of TA in tomatoes.
