Goal
Extend the shelf life of perishable foods such as fruits and vegetables.
Problem
Rapid spoilage of fresh produce leading to food waste and loss of nutritional value.
Concept Summary
Paper or cardboard sheets are coated or soaked with a suspension of fenugreek (Trigonella foenum-graecum) botanical extract. The extract provides antibacterial, antifungal, antiviral and insect-repellent properties that inhibit microbial growth on food, thereby extending freshness.
Detailed Description
The invention describes a material (e.g., paper, cardboard, synthetic sheet) that is impregnated with fenugreek seed powder or extract via soaking, coating, or incorporation during pulp manufacturing. The fenugreek particles remain embedded on or within the material, releasing antimicrobial compounds when in contact with food. The resulting "FreshPaper" sheets are placed in refrigerator drawers or packaging with produce. The paper is biodegradable, compostable and recyclable. Commercially, the product has been sold in Whole Foods stores worldwide and used by farmers and food banks.
