Keeping food fresh in the heat of El Nino
The heat due to El Nino ripens fruits quicker and spoils food faster.
Aside from keeping food in cold storage, Filipinos have been looking for a way to preserve their freshness longer.
ABS-CBN News reported that the National Institute of Physics of the University of the Philippines – Los Banos has developed a Fish Freshness Sensor that measures the gases given off by a fish.
As the fish start to decompose, the gases and odor get stronger, which light up the sensor.
A fruit coating was also formulated from agricultural by-products which prevents the early ripening of mangoes and papayas.
Because of the coating, the fruits last three times longer.
The Philippine Nuclear Research Institute and the National Crop Protection Institute of UPLB has also formulated a plant supplement from carrageenan.
The supplement promotes plant growth by up to 30 percent and strengthens palay stems.
