Post Harvest Management of Horticultural Crops

Insulation and dry ice technique

In absence of refrigeration, a certain level of temperature control during postharvest handling can be achieved with insulation (eg. polystyrene boxes) and heat sinks provided inside the packaging (eg. loose ice or ice packs). Use of external reflective and/or insulative covers (eg. thermal blankets) and heat sinks (eg. dry ice) can assist or provide an alternative to, temperature control management.
Plastic impregnated with chemicals capable of absorbing ethylene gas are also being researched.
