Rice

The VacQPack system enables rice preservation by controlling moisture content following the post-harvest drying process. The rice preservation process differs from East Asia to the Americas, dependent on multiple factors such as the type of grain, the heat and humidity of the country, and the infrastructures available for storage and processing.

Scientific studies have been discussed among professionals and specialists about quality preservation using modified atmosphere on rice. Opinions are unanimous on modified atmosphere packaging (MAP) as a valid solution to decrease spoilage and assure rice quality.

The VacQPack bulk storage, made of liners alone or covering the adopted packaging systems (outside liners), will permanently control the inner atmosphere, creating a homeostatic environment where rice can be kept in perfect physical and chemical conditions.

VacQPack has experience in treatments and preservation of both conventional and organic rice around the world. A recent practice in Thailand made an interesting case study, because it showed not only the advantages of using a package that delivers organically compliant fumigation, it also optimized the logistic process of transoceanic commerce. Finally, it showed that traditional chemical fumigation can be superseded by a purely organic approach – recognized and supported by official bodies at the origin and destination of the cargo.

Traditionally, rice is stored in open systems, warehouses, in bags, or open granaries; exposed to rain, insects, rodents, and bird attacks. Good practices says, as a storage precondition, that rice should be dried immediately after harvest at 14% humidity or less. Risks like insect infestation, proliferation of microorganisms (especially in wet rice), oxidation, and lipases all originate from poor storage conditions, and they can represent even higher costs in the case of organic rice.
