What is hypobaric storage?
Hypobaric storage involves the cold storage of fruit under partial vacuum. Typical conditions include pressures as low as 80 and 40 millimetres of mercury and temperatures of 5 °C (40 °F). Hypobaric conditions reduce ethylene production and respiration rates; the result is an extraordinarily high-quality…
What is the another name of hypobaric storage?
Hypobaric or low-pressure storage, also known as subatmospheric pressure storage, consists of a ventilated chamber, which establishes a reduced O 2 controlled environment (less than atmospheric pressure) that lowers the respiration rate of the produce and increases its shelf life.
What is CA and MA storage?
CA and MA Cold Storage Controlled atmosphere (CA) and modified atmosphere (MA) storage are technologies for extending the shelf life of foods, especially fruits and vegetables; and for eliminating pests in stored grains and oilseeds.
What is modified atmosphere cold storage?
The principle of MA storage is to replace the air surrounding the foodstuff with a mixture of CO2, O2 and N2.
Who discovered hypobaric storage?
Workman et al
the first records of hypobaric conditions being applied to the storage of fruit and vegetables was by Workman et al. coloured fruit to turn yellow while this was delayed to 56 days in storage under 152 mmHg at the same temperature.
What is cap and map?
CAP and MAP (Controlled atmospheric packaging and Modified atmospheric packaging) of food products using Nitrogen gas. Food products that are durable and perishable, how Nitrogen gas protects foods from spoilage.
What is CA storage?
Controlled atmosphere (CA) storage of fruits and vegetables refers to storage in atmospheres with reduced levels of oxygen and/or relatively high carbon dioxide concentrations, at low temperature and high relative humidity (RH).
What are the types of modified atmosphere packaging?
There are two different kinds of modified atmosphere packaging: Passive and active.
What is evaporative cooling storage?
The evaporatively cooled storage structures work on the principle of adiabatic cooling caused by evaporation of water, made to drip over the bricks or cooler pads. Generally, an evaporative cooler is made of a porous material that is fed with water. Hot dry air is drawn over the material.
What are the two types of hyperbaric chambers?
Hyperbaric oxygen therapy uses 2 types of chambers:
- Monoplace chamber. This is a chamber built for 1 person. It’s a long, plastic tube that looks like an MRI machine. The patient slips into the chamber.
- Multiplace chamber. This chamber, or room, can fit 2 or more people at once. The treatment is largely the same.
