A Technical Method of Responsive Cellophane Films for Real Time Spoilage Detection
CWSF · 2026 Health & Wellness Silver Medal
Overview
A Technical Method of Responsive Cellophane Films for Real Time Spoilage Detection is a scientific innovation experiment that identifies and tests a cellophane film fabricated with red cabbage natural pH indicators. This cellophane incorporates anthocyanins which is a water-soluble pigment that indicates pH levels based on qualitative values (colours). As a result, creating spoilage detecting films are applicable using biopolymer films with red cabbage natural indicators that detect spoilage of solid produce overtime. It was observed that pH levels from 0-7 (acidic) often range from pink and purple colours while neutral levels (7) are blue and purple, and alkaline (7-14) colours were green and yellow. This innovative experiment opens a door to future technological advancements and a potential for smart packaging. It also allows for multiple food safety benefits, transportation and storage uses, and household and grocery uses.
