Chickens breast meat enriched with propolis and/or bee pollen – implications for human health

Objectives: Propolis and bee pollen belong to a group of natural substances of animal and vegetable origin with a particularly expressed antioxidant and antimicrobial properties attributed to its phenolic bioactive compounds. Chicken meat can serve as functional foods enriched with polyphenols. The aim of this study was to produce enriched chicken meat and to determine total phenolic (TP) content in breast meat of chickens fed with feed mixtures additionally supplemented with various amounts of propolis and/or bee pollen. Materials and methods: This study was conducted on 200 Ross 308 chickens divided into five groups (control group - C, fed with feed mixture and four experimental groups - E1-E4, fed with following additions to kg of feed mixture: E1 (0.25 g of propolis + 20 g of bee pollen) ; E2 (0.5 g of propolis) ; E3 (1.0 g of propolis) ; E4 (20 g of bee pollen)). In breast meat samples the TP content was determined by the Folin-Ciocalteu method. Analysis: One-way ANOVA and LSD test were used for data analysis. Results: Mean values of TP content (mg/g) in all groups were: 78.52±13.73 (C) ; 95.32±10.55 (E1) ; 87.42±16.84 (E2) ; 92.94±14.67(E3) ; 88.56±9.82 (E4). The study showed statistically significant differences between group C and group E1 (p=0.007) and between group C and group E3 (p=0.020). Discussion: Recent studies showed that the antioxidant and anti- inflammatory properties of polyphenols may potentially prevent or serve as treatment against many non-communicable diseases (NCDs).The present study showed that dietary protocol E1 and E3 exerted the largest incorporation of phenolic compounds in chicken breast meat.Such innovative technological solution in broilers feeding enables the production of healthier meat that can be considered functional food. Conclusions: Created functional food can find its significant place in prevention and integrative treatment of major NCDs in Croatian population such as cardiovascular and cerebrovascular diseases.
