Just a minute to make a custard tart with fewer calories – Daily News – Lisbon

The University of Aveiro today announced that it has developed a pastel de nata
  “Ready to heat up in the microwave,” less calorie, and maintains the
 original features, which opens new horizons to your
 marketing and export.

The pastel de nata created in the Department of Chemistry, University of Aveiro, with “all the traditional flavor and fewer calories” can be frozen after it’s done and be consumed anywhere in the world, as if it had was just done after a minute in the microwave.

So far, the cream puffs, when subjected to freezing and reheating in a microwave, stayed with a different texture of fresh from the oven and the puff pastry was no longer crunchy.

For this reason, those who had in the market were frozen and sold as raw or semicru product, still requiring lengthy confection in a conventional oven and at elevated temperatures.

The problem was solved by the Chemistry Department (FD), University of Aveiro with the incorporation of a food ingredient-based polysaccharides added to the puff pastry and custard cream.
