Shelf life is the extension of time to the upper limit for which a food product can be kept<br />

under specific environmental condition without changes in quality and acceptability. The<br />

objective of this study is to determine the physicochemical characteristics and shelf life<br />

study of Freeze-Dried oyster mushroom powder at different storage conditions. Physical<br />

analysis which are colour value, morphology structure, hydration properties and<br />

proximate analysis that comprised of moisture, ash, protein, crude fat, fibre and<br />

carbohydrate will be performed for assessing the effect of oyster mushroom powder at<br />

15, 25 and 35ᵒC for two months storage. The analysis will be carried out in interval of<br />

one week. The shelf life of oyster mushroom powder under a storage condition of 25ᵒC<br />

is expected in the range of seven to eight months based on the critical moisture content<br />

of the powder.<br />
