How do you preserve or extend the freshness of perishable goods? 1.6 billion people do not have refrigeration in the world. 25% of edible substances and foods are estimated to spoil at various points during growth and ripening, transportation, packaging, on the shelf and in storage.
The Freshpaper invention precisely addresses the issue of preserving and/or extending food freshness, while bypassing the potential toxicity of the state of the art in chemical options. Chemical options, such as coatings, sprays and washes of various sorts, which are used as preservatives, insecticides, pesticides, fungicides or antibacterial agents to prevent or delay the onset of spoilage.
The Freshpaper invention is recited in US6372220 (B1), titled Fenugreek impregnated material for the preservation of perishable substances. The invention comprises paper that is infused with botanical extracts known for their antibacterial, antifungal, antiviral, preservative or curative properties. In particular, Freshpaper is coated with a Fenugreek seed extract botanical (trigonella foenum-graecum). A botanical that has antifungal and antibacterial properties, known to prevent the proliferation of pathogens.
Freshpaper is packaged in sheets and sold in supermarkets. The sheets are active for one month. They may be inserted in fridge drawers, in fruit cartons or salad bags. For the consumer, Freshpaper has the advantage of being a nontoxic and safe preservation method for perishable goods. For manufacturers, Freshpaper is much easier to produce than its chemical counterparts.
