The effects of post-harvest pretreatments and drying methods on in vitro bioaccessibility of phenolics and carotenoids in tomato (Solanum lycopersicum) cultivars.

ABSTRACT: Two pretreatments (ultrasound sonication [US] and microwave [MW]) and drying techniques (hot air [HA] and freeze-drying [FD]) were used to assess the in vitro bioaccessibility of phenols, carotenoids, and antioxidant activity in three tomato cultivars (Zzx171, Zzx162, and Zzx65). The metabolome-chemometric analysis showed that tomato cultivars dried by FD and HA differed in metabolites. HA samples contained methoxytyrosine and aconitane-type diterpenoids. US-HA enhanced total phenol content bioaccessibility by 64.72%-74.25% in three tomato cultivars after digestion (intestinal phase). US-HA increased the protocatechuic acid levels in all three tomato cultivars in the intestinal phase, but by 55.23% in Zzx65 compared to the undigested samples. Despite all adopted postharvest pretreatments a
