The effect of post-harvest treatment on the rate of weight loss from tomatoes during storage

Risch, Eric January 1977 (has links)
The moisture loss and changes in colour and firmness of tomatoes in storage were investigated using a 4x4x5 factorial experiment. The first factor selected involved four delay times after harvest, before cooling. After harvest, the tomatoes were left at room temperature for 0 hours, 10 hours, 20 hours and 30 hours, respectively, before being cooled. The second factor involved four pre-storage treatments to reduce moisture loss : (a) wrapping the individual tomatoes in polymeric film, (b) waxing the calyx or stem ends only, with a fruit wax, (c) applying wax to the whole surfaces of individual fruits, and (d) control, with no treatment. The third factor consisted of five controlled temperature and humidity storage environments : a) 10°C and 90% rh (relative humidity); b) 15°C and 88% rh; c)10°C and 60% rh; d)15°C and 50% rh; and e)18°C and 40% rh. An analysis of variance of the results showed that individually wrapping tomatoes in polymeric film resulted in the lowest rates of weight, loss during the steady state. Also the rate of weight loss from a tomato was found to be influenced by the storage condition (combination effect of temperature and humidity), and the air flow characteristics inside the storage chamber. / Applied Science, Faculty of / Mechanical Engineering, Department of / Graduate

Modification of the incidence of surface damage symptoms in sweet cherries by pre- and postharvest treatments

Lidster, Perry David January 1979 (has links)
The prevention of storage disorders in sweet cherries resulting from mechanical damage was investigated. Pre- and post-harvest treatments were applied to modify fruit texture, fruit composition and fruit desiccation in storage. The effects of the treatments applied were related to fruit susceptibility to the incidence of fruit bruises, surface markings and surface pitting. The application of calcium in the form of pre-harvest sprays or post-harvest dips decreased mechanical damage expression. Warm fruit was less susceptible to mechanical injury than cold fruit early in the storage period but fruit temperature had little effect after 8 days of cold storage. Similarly, high storage temperatures enhanced pitting development early in the storage life but storage temperatures had negligible effect after 8 days. A delay in 0℃ storage prior to bruising greatly reduced the susceptibility of cherries to mechanical injury. Fruit was most resistant to mechanical damage after 8 days in 0°C. The development of fruit symptoms in response to impact was enhanced by rough surfaces. Slowly applied compressive forces resulted in low incidences of injury symptoms. Fruit firmness and bioyield values were increased with mesocarp calcium from preharvest sprays and post-harvest dips, but did not show consistent relationships to the susceptibility of fruit to mechanical damage. Weight loss enhanced by low relative humidity increased the rate of development of damage but did not influence the total damage incidence. Soaking fruit in water or fungicide solution increased damage expression in storage. Less mature and intermediate maturity fruit were more susceptible to mechanical injury than were the most mature fruit. Fruit with relatively high alcohol insoluble solids content associated with pre-harvest gibberellic acid sprays or advanced maturity fruit had reduced susceptibility to mechanical damage. Large fruit was less susceptible to mechanical damage and had higher alcohol insoluble solids content than did small fruit. High levels of fruit nitrogen were associated with high susceptibility to mechanical damage. A great many factors were found to modify fruit susceptibility to surface disorders resulting from mechanical damage. This provides a great flexibility to producers and marketing agents to minimize fruit losses due to the effects of rough handling. / Land and Food Systems, Faculty of / Graduate

Storage quality of lettuce leaves as affected by kinetin and abscisic acid

Hemapat, Thosporn January 1973 (has links)
Some effects of post-harvest treatments of abscisic acid (ABA) and kinetin on the maintenance of quality and consumer appeal were studied on young lettuce plants. The treatments employed two concentrations of abscisic acid (1 and 5 ppm), one concentration of kinetin (20 ppm) and a combination of 5 ppm abscisic acid and 20 ppm kinetin. The plants were sprayed to the run-off point and placed in a storage chamber at 3±1°C with relative humidity close to 100%. After 6 weeks of storage all lettuce including untreated controls were in good condition. The chemical treatments did not have any distinct effect on the quality of lettuce as evaluated by a panel of observers for visual quality rating. The 20 ppm kinetin retarded chlorophyll degradation when compared to the control or the ABA-only treatments. Considering chlorophylls A and B separately, the kinetin-treated plants showed a significantly higher chlorophyll A content than other treatments, including the control. The differences in chlorophyll B content followed the same trend but only approached the 5% level of significance. ABA in the 5 ppm + 20 ppm kinetin treatment had a mild antagonistic activity to kinetin, and hence reduced the effect of kinetin on both chlorophyll A and B. Measurement of chlorophyll contents and adjustment to the original fresh weight before the samples were put in storage, provided a common basis to make comparisons for the study of chlorophyll degradation as functions of storage time and chemical treatment. Means of chlorophyll contents reported on this basis showed a trend of degradation from the 5th week to the 7th week. Temperature at 3±1°C and high relative humidity in the storage appear to be favourable for keeping lettuce. Hygenic preparation of the storage chamber also resulted in disease-free product even at the end of 7 weeks in storage. / Land and Food Systems, Faculty of / Graduate
