Embodiment 1
[0156] Example 1: Study on the Effectiveness of Preparation 3 in Delaying the Browning of Pome Fruits
[0157] A study was carried out to evaluate the control of browning by different fruit preservation options, most of which were based on Formulation 3 preparations alone or in combination with different additives DPA and ethoxyquinoline.
[0158] The trials are handled as follows:
[0159] Formulation 3 diluted to 2% (v / v) was applied by soaking a total of 1800 kg Granny Smith apples. The fruit was picked at an early stage and then stored for 6 months under controlled atmosphere (CA) and normal refrigeration (NC). CA and NC, 0.5°C, 90-9% relative humidity (RH).
[0160] The following properties were evaluated under each storage condition:
[0161] Table 8. Properties evaluated during the trials of Formulation 3
[0162]
[0163]Sampling and serial analysis of each laboratory compartment in which the trial was conducted was performed.
[0164] in conclusion:
[0165] ...
Embodiment 2
[0166] Example 2: Study of the Effectiveness of Formulation 1 in Postharvest Treatment
[0167] In this effectiveness study, Formulation 1 described in Table 4 of this application was applied in 4 facilities where 4 postharvest treatments were applied to fruit using different concentrations of the formulation and fruit under different conditions .
[0168] 2. A-Factory 1 (Lleida, Spain) :
[0169] method:
[0170] Pears removed from the compartment were applied 0.2% (v / v) of Formulation 1 in the pots of the unloader on the factory line. The fruit was previously treated with 1-methylcyclopropane (1-MCP) and the control samples showed significant problems caused by friction on the production line and physiological disturbances caused by beating and friction on the production line and in brushes. Disease and browning.
[0171] After one week of treatment, the following results were observed:
[0172] Controls without post-preservation treatment: >30% had damage from fricti...
Embodiment 3
[0200] Example 3: Study of the Effectiveness of Formulation 2 in Postharvest Treatment
[0201] 3. A-Factory 5 (Lleida, Spain):
[0202] method:
[0203] In this effectiveness study, formulation 2 containing sunflower lecithin, described in Table 5 of the present application, was administered at a facility where the formulation was used at a concentration of 0.4% (v / v) in pears from controlled After removal from the atmosphere (CA) chamber and postharvest treatment before entering the normal atmosphere (NA), it then spends approximately 20 days in NA on the production line. This study was performed to verify 1) the delay in the onset of physiological browning when transitioning from CA to NA, and 2) verify the effectiveness of controlling browning caused by friction on the production line and maintaining it after passage through CA and subsequent passage through NA. Effectiveness in good appearance and marketability and making fruit marketable.
[0204] The results obtain...
