New gauge tests orange's flavor before peeling
To combat this, Sainsbury's 'Waste less, save more' campaign invested £10 million into developing a device which they call 'The Goldilocks Gauge'. The test identifies the perfect balance of sugar and acid in satsumas, tangerines, easy peelers and oranges. With the test, consumers can check their fruits potential before peeling and potentially save tons of food.
