With the advent of controlled atmosphere cold storage, storage and long-time availability of seasonal fruits is now possible. This technology is mainly useful for long term storage of perishable fruits. In this type of cold storage, besides temperature, concentration of oxygen, carbon dioxide, ethylene and nitrogen are also controlled and maintained as per the requirement of the stored material. As relative humidity plays a major role in ripening of these fruits, these storages are technically sound to delay ripening at temperatures above the chilling range in RH modified atmosphere. With our ultra-low oxygen cold storage, perishable fruits can be stored for much longer.
Typically in a controlled atmosphere cold storage, the gas atmosphere needs to be checked and controlled continuously. The respiration rate of the food products causes the change is the atmosphere over some time. A lot of precision and expertise is required in using this technology as too high levels of some gases like oxygen or carbon dioxide can cause injury to the fruit or vegetable. The modified atmosphere delays the respiration rate, delays ripening and prolongs storage life. But it needs to be taken into account that there should not be any physical injury to the product or change in physiology, no formation of undesired odour or fungal infestation or the flavor of the product should not change.
One of the biggest advantage of controlled atmosphere cold storage is besides making a product available for longer duration of time, it reduces the use of post-harvest chemicals used for protection against insects and microorganisms. The kind of atmosphere maintained for the food storage does not support the growth of microbes.
These kinds of storages need great precision and expertise in designing and implementation. Also, constant monitoring by skilled people is required timely. With almost two decades of experience behind us, our experienced team is adept in handling such modifications and technology. We have successfully implemented projects that involved storing apples, litchis, mangoes, pears, lemons etc.
Temperature controlled cold storage is mainly used for storage of grains, dry fruits, spices and non resperate produce. In this type of storage, constant pre-determined temperature is maintained throughout the room to create an ideal atmosphere for storing sensitive food items.
These units are normally insulated and are equipped with ventilation and heating or air conditioning for greater temperature stability. Depending on the location of the unit and the produce that needs to be stored, provision for both high and low temperature is kept. The temperature can vary and are completely different from normal room temperatures as some people think.
At Natural Storage Solutions our professionals use the latest technology and quality products for designing superior Temperature Controlled Cold storage units. A uniform temperature is maintained throughout the unit in minimal power consumption. We ensure uninterrupted operation and noiseless functioning while maintaining the freshness of the good stored till they reach the customer.
Modified Atmosphere Cold storage is used mainly for the storage of fresh vegetables. In this type of storage, a modified atmosphere is created and maintained. This is done by maintaining a pre-determined temperature and high humidity throughout the room.
The technology behind this kind of atmosphere extends the shelf life of foods, especially fruits and vegetables. The main focus of this technology is to reduce the respiration rate of the food product which causes early ripening and decay. Although Modified Atmosphere Cold storage provides lesser control that a controlled atmosphere cold storage, the former also thrives on the modification of temperature and gaseous composition of the storage room. An optimal balance of oxygen and carbon dioxide is maintained which is critical and different for each product.
The idea is to control respiration, retard the microbial growth specially molds and minimize enzymatic spoilage. The chlorophyll breakdown is delayed which results in higher colour stability and maintaining the visual appeal of the food item. Modified atmosphere can extend the shelf life of meat, poultry, fish, grains, oilseeds, fruits and vegetables.
Natural Storage solutions Pvt. Ltd. provides total storage solutions for root vegetables like onion, garlic, carrot, processed potatoes etc. This type of storage system is very useful for the control of sugar level in the products like potatoes which is in high demand by food processing industries.
