Fallopia japonica (FJ), an invasive plant species known for its rich bioactive compounds, has been used for centuries in traditional Chinese medicine. Despite its significant beekeeping potential, this aspect of FJ remains underexplored. This research aims to investigate the antimicrobial and antibiofilm properties of FJ plants and honey. Notably,...
This study evaluates the suitability of three lactic acid bacteria (LAB) strains—Lactiplantibacillus plantarum, Lactobacillus acidophilus, and Apilactobacillus kunkeei—for use as probiotics in apiculture. Given the decline in bee populations due to pathogens and environmental stressors, sustainable alternatives to conventional treatments are necess...
The present study investigates the impact of solid-state fermentation on bee-collected pollen using a consortium of Lactobacillus plantarum, Apilactobacillus kunkeei, and Lactobacillus acidophilus. Another aim is to compare the nutritional and bioactive properties of natural versus fermented pollen, focusing on macronutrient composition, pH, acidit...
Due to the increased emergence of drug-resistant bacteria, the declining efficiency of traditional antimicrobials has generated severe concerns in recent years. Subsequently, more interest in other antimicrobial agents from natural resources draws more attention as an alternative to conventional medications. This study investigated the bactericidal...
Bee bread (BB) is a fermented mixture of bee pollen, is rich in proteins, amino acids, fatty acids, polyphenols, flavonoids, as well as other bioactive compounds, and is considered functional food for humans. In this study, we explored an innovative green synthesis of colloidal silver nanoparticles, using BB extracts as reducing and stabilizing age...
Consumption of plant-based milk replacers has increased in recent years due to health benefits, benefits attributed mainly to the content of phenolic compounds, fatty acids, or bioactive compounds with antioxidant activity. In this context, we proposed to obtain two types of less studied plant-based beverages, namely lupine and chickpea beverages,...
: Consumption of plant-based milk replacers has increased in recent years due to health benefits, benefits attributed mainly to the content of phenolic compounds, fatty acids, or bioactive compounds with antioxidant activity.

The present study was carried out to evaluate and compare in vitro antioxidant (2,2-diphenyl-1-picrylhydrazyl (DPPH), Trolox equivalent antioxidant capacity (TEAC), and ferric reducing antioxidant power (FRAP)), antimicrobial, anticancer activities, and the individual carotenoids and anthocyanins content of methanol extracts of the Cyclamen genotyp...
The aim of this study was to determine the botanical origin, phenolics, flavonoids and fatty acids content, antioxidant and antimicrobial properties, of 18 bee collected pollen (BP) samples from Turkey and Romania. Five plant families with predominant pollens (>45%) were found in the Turkish samples, and only three in the Romanian samples. The phen...
Bee pollen is commonly reputed as a rich source of nutrients, both for bees and humans. Its composition is well balanced and can be taken as a stand-alone food or as supplement, including for the elderly owing its low caloric value. However, storage conditions frequently lead to product degradation, namely due to the high moisture content that enab...
Currently, the antibacterial properties of honeydew honey are increasingly valued, being regarded as superior to blossom honeys. Over the years, the antibacterial activity of propolis has been highly appreciated, due to the flavonoids and phenolic acids present in its composition. Moreover, essential thyme oil and sea buckthorn oil have been recogn...
Honey, the sweet natural substance produced by honeybees is currently considered one of the nature’s most powerful products. Natural honey can be regarded as a nutraceutical product due to its nutritional benefits and therapeutic promises. In addition to this, the use of honey as food and medicine has been embraced by different civilizations, from...
Beebread (BB) is a fermented bee product made from plant pollen, honey and bee saliva. The nutritive and biological compounds of BB vary greatly depending on the diversity of flora and the season of pollen collection by bees. In order to evaluate this valuable bee product potential, thirteen BB samples were analyzed on the nutritive proprieties and...
Țaga cheese is a traditional Romanian smear-ripened cheese made from bovine milk and identified with the name of the village and caves where it is produced. As no previously reported microbiological and chemical studies have been undertaken on this product, this research aimed to investigate the microbiological and biochemical characteristics which...
Pollen analysis is the basic method for the determination of the botanical and geographical origin of honey. However, the presence of over-represented pollen in honeys may lead to false results of the analysis. This can be more severe if this pollen is present in unifloral under-represented honeys of commercial importance (e.g. thyme or acacia hone...
Honey is used for centuries both as nutrient and in medicine, being an exhaustless source of benefic factors for health and also for different biotechnological processes. This is a complex matrix which possesses antioxidant and antimicrobial properties due to its peroxidic activity and bioactive compounds. A fully validated approach for the determi...
In recent years, food products manufactured with buckwheat and sprouts flours have attracted widespread interest due to their high nutritional value with various health benefits, becoming more and more popular. The purpose of this study was to assesses the influence of buckwheat and sprouts flours on the nutritional, sensorial and textural characte...
Lactobacillus plantarum ATCC 8014 was used to ferment quinoa flour, in order to evaluate its influence on the nutritional and rheological characteristics of both the sourdough and muffins. The quantification of carbohydrates and organic acids was carried out on a HPLC-RID system (high-performance liquid chromatography coupled with with refractive i...
As mammals provide passive trans-placental immunity to the fetus, a similar mechanism is recorded in poultry, where immunity comes from egg fluids and is called vitelline immunity. In poultry, while the egg is in the ovary, the serum immunoglobulin Y is transferred in the egg yolk, and during the passage of the egg through oviduct, the immunoglobul...
Abstract: Hippophae rhamnoides L. is an important source of natural antioxidant and antimicrobial agents. Phytochemical compounds, antioxidant and antibacterial properties of berries, and leaf extracts from four Romanian sea buckthorn cultivars were investigated. Large differences in the content of total polyphenols and flavonoids between the varie...
Staphylococcus aureus is an extraordinarily adaptable pathogen with a proven ability to develop resistance. It is notorious for its ability to become resistant to antibiotics. Infections that are caused by antibiotic-resistant strains often occur in epidemic waves that are initiated by one or a few successful clones. Also, it is a virulent pathogen...
The current study was carried out in order to determine the effects of simple phenols and of specific anti-methanogen IgY antibodies on ruminal gas production, methane emissions, volatile fatty acids (VFA) profile and pH in in vitro ruminal cultures. Caffeic and p-Coumaric acids and IgY antibodies were added anaerobically to ruminal batch cultures....
Plums are low-calorie fruits with a low glycaemic index score. Prunus domestica L. is one of the tree fruits threatened by Plum pox potyvirus (PPV), a quarantine disease that causes fruit loss to plums and other stone fruits. HoneySweet is a plum tree created to be resistant to this virus. Beside genetical determinations, chemical composition and n...
