Embodiment

[0073] method:

[0074] Harvest pears at maturity (Caufreness, Williams / Butrick, or Peckerman) for long-term storage. The number of fruits and the number of replicates were chosen according to the size of the chamber in which 1-MCP was applied and according to the statistical design. An airtight container with a size of approximately 1 cubic meter was used to apply 1-MCP and ethylene. From SmartFresh containing 0.14% by weight 1-MCP TM The powder (available from AgroFresh, Inc.) released 1-MCP. to SmartFresh TM The amount of powder is selected to obtain the target 1-MCP atmosphere concentration in the selected container. For example, in a 1 cubic meter container, 1000 mg of SmartFresh TM The powder released 1-MCP and a 1-MCP concentration of 625 ppb in the atmosphere was obtained.

[0075] Add the selected amount of SmartFresh TM The powder was dissolved in water, added to an airtight flask, and shaken until all the powder was dissolved. The flask was then placed in an ...

Embodiment 1

[0088] Example 1: South Africa (South Africa) / Williams Pears (William's Pears) / RA Conditions 8 weeks / 5 days at ambient conditions

[0089] The firmness measurements (kgf) measured on pears from three farms were as follows:

[0090] sample

[0091] The various samples treated with both 1-MCP and ethylene had acceptable hardness, which was lower than the corresponding 1-MCP only treated sample and higher than the corresponding low hardness control sample.

Embodiment 2

[0092] Example 2: Under South Africa / Williams Pears / RA Conditions 8 or 12 weeks / 5 days at ambient conditions

[0093] The hardness test results (kilogram force) are as follows:

[0094] sample

[0095] 300(C)

[0096] Pears treated with both 1-MCP and ethylene were softer than corresponding pears treated with 1-MCP only, but harder than corresponding control pears.

Abstract

There is provided a method of treating produce comprising the step of exposing said produce to an atmosphere containing (i) 100 ppb to 5,000 ppb by volume of one or more cyclopropene compound, and (ii) ethylene, wherein the ratio of ethylene concentration by volume to cyclopropene concentration by volume is from 0.1:1 to 8:1.

Description

technical field [0001] The present invention relates to the handling and storage of agricultural products. Background technique [0002] US 2006 / 0160704 describes a method of contacting plants with cyclopropene compounds and non-cyclopropene compound plant growth regulators. A plant growth regulator other than cyclopropene disclosed in US 2006 / 0160704 is ethylene. The method of US 2006 / 0160704 relates to the treatment of plants and is disclosed to be useful for increasing the yield of treated plant-derived crops. The method of US2006 / 0160704 does not address the problem of how to treat harvested produce to improve its response to storage conditions. [0003] In particular, there is a need to provide a method of treating produce that addresses the problem of overactivity of produce in contact with cyclopropene compounds after harvest. The agricultural products are resistant to spoilage after exposure to cyclopropene compounds after harvest, but have difficulty developing c...
