Abstract(s)
Betalains are a group of secondary metabolites named chromoalkaloids that are synthesized from tyrosine. These compounds have gained
some attention in the last few years mainly due to their interesting bioactive potential, namely antioxidant, antimicrobial, and other
bioactive properties [1]. Their strong and vibrant colours are also one of the characteristics by which these compounds have gained
visibility in the food and pharmaceutical industries [2]. Betalains can be divided in two groups regarding the colour range: betaxanthins in
the orange to yellow range, and betacyanins in the purple to pink range. Thereby, these compounds can be used as natural colouring
agents, providing alternatives to the massively used artificial counterparts [3]. Although there are already some natural options in the
market, these are not enough to meet the needs of the food industry, due to the growing concern of consumers regarding what they eat.
