Abstract:
Lactobionic acid (LBA) shows singular properties (antioxidant and antimicrobial). However, few studies aim to test them in foods and confirm the actual occurrence of properties. The present study aims to apply LBA/lactic acid in the production of requeijão cremoso model in order to recognize some of the effects caused by the component as a food additive. The effects on the requeijão cremoso model were evaluated by the final properties of the product: water activity, rheological properties, antioxidant and antimicrobial capacity. Model of requeijão completely acidified with LBA showed the maximum antioxidant activity (88%). The results revealed a potential of application of LBA for microbial inhibition. All model produced presented pseudo plastic behaviour.
