Table 8 reports data relevant to the color changes of the beverage during storage at the selected temperatures.
Accelerated shelf life testing temperature for food.
Accelerated shelf life testing.
One week under these conditions was thought to equate to one month of normal storage for most fat based confectionery products and those containing nuts.
Q10 shelf life at temperature t c.
The q10 value of a product is the temperature quotient for a 10 c temperature difference as expressed in the equation below.
Elevated temperature or humidity are applied to eligible products to predict product shelf life over extended periods of time up to 1 year.
Increasing the temperature and or humidity will provide data that can then be used to project an estimated shelf life.
Accelerated shelf life study is performed by increasing the storage parameters time temperature humidity of the incubator conditions.
In order to perform the shelf life test under accelerated conditions the beverage was stored at 30 c 40 c 50 c and 60 c for up to 8 months.
Barnett 1980 suggested an accelerated test where packaged products are alternated daily between storage temperatures of 26 7 c 80 f and 15 6 c 60 f for 6 12 weeks.
