Consumer interest in healthier meat products has grown in recent years. Therefore, the
use of plant powders as natural preservatives in the composition of pork and beef products could
be an alternative to traditional meat products. This study aimed to assess the effect of different
powders, such as blackcurrant, chokeberry, rowan berries, apple, tomato, garlic, and rhubarb, on
the microbial growth dynamics in minced pork and beef during refrigerated storage. The total
counts of aerobic microorganisms, Pseudomonas spp., yeasts, and molds were examined according
to ISO methods. The polyphenolic profiles of plant powders and supplemented minced pork and
beef samples were determined by HPLC-MS. The antioxidative capacity of the plant powders was
analyzed using a spectrophotometric method. The findings of the study revealed that supplemented
minced pork and beef samples had similar polyphenolic profiles and microbial growth dynamics.
The highest antioxidative capacity was observed for anthocyanin-rich berry powders. In both minced
pork and beef, rhubarb powder was the most effective plant material for inhibiting microbial growth,
followed by blackcurrant pomace powder. In conclusion, all of the plant powders used in the present
study can be used for the valorization of minced meat products, providing both antimicrobial and
antioxidant effects.
