The effect of antifungal extracts on the contamination of grain with microfungi

Abstract

The study aimed to analyze the effects of extracts made from buckwheat grain, hulls, and bee products (propolis, bread, and pollen) and extraction solvents on the growth of microfungi on a medium and on buckwheat, wheat, oat, and maize grain. Research findings suggest that bioactive compounds contained in buckwheat grain reduced the amount of Fusarium spp. in the grain kept in the antifungal extract for 90 min at 25°C temperature. Buckwheat hull extract was more effective in inhibiting mycelial growth of mycotoxin‐producing Fusarium culmorum and Fusarium graminearum compared with buckwheat grain extract (13%–50% and 14%–36%, respectively). The antifungal activity of extracts of bee products did not depend on the content of phenolic compounds in them; however, it depended on the grain species treated. After treatment of oat, wheat, and maize grain with bee product extracts, the lowest concentration of microfungi was identified on oat grain. More significant analysis results were obtained for the samples where ethanol solvent had been used for the preparation of extracts.

Patterns of Phenolic Compounds in Betula and Pinus Pollen

“…Phenolic compounds are important for the development and functions of pollen of anemophilous plants: they participate in the synthesis of sporopollenin and affect its stability [ 5 , 53 ], while bioactive properties help to protect the exine and intine [ 54 ]. Pollen phenolic compounds in the human diet are studied for both quantification and bioactivity determination [ 8 , 21 , 22 , 55 ]. Meanwhile, knowledge on the emission of phenolic compounds into the environment from naturally degrading pollen in ecosystems is very scarce.…”

“…Pollen of entomophilous plants collected by bees is more valued in the human diet due to its health-giving properties [ 20 , 21 ] and the antifungal impact of its bioactive compounds [ 22 ]. Although pollen of anemophilous plants is characterised by higher purity and more stable components in comparison with entomophilous pollen, it is used less frequently for human needs [ 23 ].…”

Antifungal Activity of Chitosan Oligomers–Amino Acid Conjugate Complexes against Fusarium culmorum in Spelt (Triticum spelta L.)

“…Hill and L.A.S. Johnson) [16], essential oils of Moroccan wormseed (Dysphania ambrosioides (L.) Mosyakin and Clemants) [17], walnut (Juglans regia L.) green husk extracts [18], extracts from buckwheat grain and hulls [19], phenolic-rich bee products (propolis, bread and pollen) [19], or polyphenol inclusion compounds and conjugate complexes [20,21], among others, have been recently reported.…”

Chemical and Organoleptic Properties of Some Dairy Products Supplemented with Various Concentration of Propolis: A Preliminary Study

“…Generally, naturally occurring polyphenols and vitamins as part of the food chain are classified as essential and non-essential compounds, and these are considered bioactive ingredients [1][2][3][4][5][6][7]15]. In particular, these compounds naturally exist in food and provide many benefits to health through ingestion [2,[5][6][7]9,16,17]. Phenolic compounds are In conclusion, according to propolis has distinct efficacies with significant nutritional properties and functional values, propolis could be effective in improving the health benefits for human [20].…”
