20.500.12556/DKUM-94205 Impact of storage conditions on stability of bioactive compounds and bioactivity of beetroot extract and encapsulates Background: In this study, bioactive compounds (phenolics and betalains) extracted from beetroot were stabilized by encapsulation with maltodextrin and soy protein by the freeze drying method. Stability of bioactive compounds and bioactivities in a beetroot extract and encapsulates during 60 days of storage at 4 ◦C (without light) and at 25 ◦C (with and without light) were investigated. (2) Methods: Contents of bioactive compounds and bioactivity (antioxidant activity by DPPH, RP, and ABTS tests; anti-inflammatory and antihyperglycemic activity) were determined. Improvement in stability of bioactives’ content and bioactivity of prepared encapsulates in relation to the extract was observed after storage at room temperature under light conditions. (3) Results: Encapsulation with maltodextrin showed improvement in stability of all studied bioactive parameters, while an encapsulate with soy protein improved stability of bioactives and antioxidant activity compared to the extract. The encapsulated beetroot extract represents a promising food additive for functional foods due to their content of bioactive compounds and consequent bioactivities. isolation phenolic copound colorants formulation functional foods izolacija fenoli barvila true false true Angleški jezik Slovenski jezik https://www.mdpi.com/journal/processes © 2024 by the authors Članek v reviji 2025-08-08 09:47:49 2025-08-08 09:47:49 2025-08-09 03:20:03 0000-00-00 00:00:00 2025 0 0 18 str. iss. 7, [article no.] 1345 Vol. 12 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2025-05-20 2025-06-14 2025-06-28 66 244831491 10.3390/pr12071345 2227-9717 processes-12-01345.pdf processes-12-01345.pdf 1 9539922DDD9E879012ACAF6D7FC51727 5fce1b714d832fb2c9e949bde967ec67408a180f97476743853a6d6f72f98e89 4872a62a-742c-11f0-bafb-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=194940 Fakulteta za kemijo in kemijsko tehnologijo Medicinska fakulteta 0 0 0
