A New
Method in
Organic
Food
Preservation
Keep food fresh with BFRESH
Foods are perished due to spoilage & decay
Food spoilage and decay make food un-edible and can lead to human
morbidity and mortality
Food spoilage and decay lead to
 Degradation of food quality
 Loss of color
 Loss of flavor
 Loss of texture
 Loss of aroma
 Contamination by microorganisms
 Contamination by toxins
Causes of food spoilage
Food spoilage is due to



Autolysis: Self – decomposition of food by Oxidation, Enzymes, and
Metal ions
Microbial decomposition
Damage by external factors (insects, rodents, dust, odor, fumes, and
mechanical, fire, heat or water)
Causes of food decay
Food decay is due to



Putrefaction
Fermentation, a metabolic process whereby electrons released from
nutrients are ultimately transferred to molecules obtained from the
breakdown of the same nutrients
Rancidification from chemical decomposition of fats, oils and other
lipids
Food losses occur for all types of food
 Each year, industrialized and developing countries dispose of roughly similar
quantities of food
 25 to 35% of world food production is lost through natural causes such as
pests, microbes, and insects
 The post-harvest losses of fruits and vegetables in the developing countries
account for almost 50% of the produce.
 Annual supermarket losses are
 11.4% for fresh fruit
 9.7% for fresh vegetables
 30% for cereals
 4.5% for fresh meat, poultry, and seafood
A new organic method for food preservation
Loss-adjusted food for fresh apples
Loss from farm to retail: 4%
Loss from retail to consumer: 12%
Loss at consumer level: 29%
(includes spoilage, plate waste,and losses from inedible parts (stems and cores)
Total loss: 45%

A new organic method for food preservation
Our techology uses 3-4 compounds to preserve food.




Compound A. This compound retards the food ripening (fruits and
vegetables), retards food spoilage (spoilage that are dependent on
enzymatic reactions), food decay and prevents growth of
microorganisms.
Compound B. This compound amplifies the action of compound A and
retards the food ripening (fruits and vegetables), retards food spoilage
(spoilage that are dependent on enzymatic reactions), food decay and
help to prevent growth of microorganisms.
Compound C. This compound removes water in the container to
prevent food spoilage and decay.
Compound D. This compound amplifies the action of compound A and
retards the food ripening (fruits and vegetables), retards food spoilage
(spoilage that are dependent on enzymatic reactions), food decay and
help to prevent growth of microorganisms.

OTHER USES
Besides food preservation, our technology has many other
uses due to its inherent disinfective and decontamination
properties. These include among others
1. Providing fresh food in remote sites, in war theatre, and
in inter-planetary journeys
2. Creation of drinking water from contaminated water for
cities across the globe and in remote areas
3. Changing the refrigerator of today to a new device
capable of longer term storage as compared to mere 40C
prevention that it currently offers

Providing sterilization of equipment, products and
any item when autoclave is not available or not suitable
such as sterilizing of medical instruments, devices that melt
or disfigure at high temperature or in remote areas where
sterilization is not available such as in war theatre
5.
Providing sterilization at home, for example in
shower area to rid the surfaces from microorganisms
