Abstract
Background
• Americans throw away roughly 3.9 billion gallons of milk annually [1].
• Over 30 million tons of CO2 was emitted to produce this wasted milk [2].
• Much of this waste is the result of consumer reliance on inaccurate or misleading expiration labels [3].
• Manufacturers label milk with expiration dates prior to actual spoilage times to avoid lawsuits related to food poisoning.
Problem Statement
• Expiration dates provided to consumers are unreliable. Currently, there are no consumer products that assist consumers in determining actual spoilage of milk.
Planned Solution
• Develop an apparatus to accurately and reliably measure pH of the milk to determine the spoilage date.
• Develop pH circuit for accurate measurement of pH.
• Provide user with notification when milk has spoiled.
