Effect of storage on β-carotene content and microbial quality of dehydrated carrot products

•The change in β-carotene content of dehydrated carrot products was studied.•Change in β-carotene of dehydrated carrot in different packaging materials was noted.•The microbial profile and safety of dehydrated carrot after six months storage were noted.•The storage period had effect on the colour of carrot powder in all the packaging materials.

The study analysed the influence of dehydration and preparation method on β carotene content and microbial quality of fresh carrots and dehydrated carrot products during storage period up to six months in three different packaging materials at room temperature. The β-carotene content reduces as the storage progresses. The aluminium laminated pack (ALP) retained higher β-carotene content after six months followed by plastic jar and glass jar.
