Development of a High-Fibre Multigrain Bar Technology with the Addition of Curly Kale

Round 1

Reviewer 1 Report

This article has confusing structure with the results and conclusions preceding the methods

There is not clear methodology of the addition of kale

Plenty of cereal bars are created every day, there is not anything in particular recipe

The Aw remains high and there is no explanation about the effect to the shelf life. Actually there is no proposed methodology for the shelf life estimation

The DF content and the antioxidant capacity induced by the kale is minimum in relation to the base bar. The base bas is already a good snack, particularly the one with black currants.

What is the point of adding Kale when you have a product that has shorter shelf life, is more expensive due to the addition of Kale or the MA Packaging and has almost no added nutritional value

There is no reference to the EU legislation about nutritional and health claims
