Abstract/OtherAbstract:
A study was made of the effect of high-pressure processing (HPP) and thermal treatment (TT) on plant bioactive compounds (tocopherols, carotenoids and ascorbic acid) in 12 fruit-juice milk beverages, and of how the food matrix [whole milk-(JW), skimmed milk (JS) and soya milk (JSy)] modulates their bioaccessibility (%). HPP (400 MPa/40ºC/5 min) produced a significant decrease in carotenoid and ascorbic acid bioaccessibility in all three beverages, and maintained the bioaccessibility of tocopherols in JW and JS, while decreasing it in JSy. TT (90ºC/30 s) produced a significant decrease in tocopherol and carotenoid bioaccessibility in all three beverages, and increased the bioaccessibility of ascorbic acid. Regarding the food matrix, α-tocopherol and ascorbic acid bioaccessibility was greatest in JW-beverages and lowest in JSy-beverages, while no significant differences were found among the three beverages in terms of carotenoid bioaccessibility. HPP-treated samples showed higher tocopherol and carotenoid bioaccessibility than TT-treated samples, thus indicating that HPP combined with a milk matrix positively modulates the bioaccessibility of certain types of bioactive components of food, mainly those of a lipophilic nature.
