A protocol of enzymatic water extraction was developed to isolate antiradical and DNA damage inhibitory polysaccharides from Epimedium brevicornu (EbP) using single factor experiments and orthogonal test for the first time. Compared to conventinal heating extraction, enzymatic water extraction dramatically enhanced extraction yield, shortened extraction duration, reduced extractant consumption and decreased extraction temperature. Structural features of EbP were investigated by infrared spectroscopy. And some other physicochemical properties like solubility of EbP were identified. EbP obtained by enzymatic water extraction exhibited ability to scavenge DPPH• and ABTS+• radicals. Consistent with their free radical‐scavenging activities, Epimedium polysaccharides possessed protective effect against plasmid DNA damage induced by oxidative stress. In summary, enzymatic water extraction seems to be a promising technique for separating Epimedium polysaccharides, which might act as a natural antioxidant or a chemopreventive agent due to their free radical‐scavenging capacity and protective activity against DNA damage caused by oxidative stress. Practical Applications Polysaccharides are considered one of the most important bioactive constituents in the famous edible medicinal plant, Epimedium brevicornu. In the present study, enzymatic water extraction of polysaccharides from Epimedium brevicornu was optimized for further large‐scale industrial processing for the first time. Epimedium polysaccharides obtained by enzymatic water extraction have proved to possess antioxidant and DNA damage inhibitory activities, which show great potential for becoming a nutraceutical in healthy foods or even a phytopharmaceutical.

“…Such solutions also can give rise to a series of environmental pollutions and involve unnecessary derivatives [11]. Biological techniques are usually realized with the help of quiet a few enzymes, for example pectinase and cellulose [12]. These reactions still have some shortcomings, such as enzymatic hydrolysis of cellulose usually happen at relatively harsh reaction conditions, enzymes are difficult to infiltrate into inner cell as its macromolecular structure and thus they just can disrupt the structure of the plant materials surface.…”

Rokaityte A., Zaborskiene G., Macioniene I., Rokaitis I., Sekmokiene D. (2016): Combined effect of lactic acid, bioactive components and modified atmosphere packaging on the quality of minced meat. Czech J. Food Sci., 34: 52-60.The quality of minced beef was improved. Combinations of modified atmosphere packaging (MAP) and vacuum packaging (VP) with lactic acid (LA), dihydroquercetin (DHQ) and linalool (LIN) mixes were used on fresh minced beef. In the course of the study the total aerobic bacterial, escherichia coli, yeast and mould counts and formation of biogenic amines during 9 days of storage at +4°C temperature were investigated. Mixtures of DHQ+LA+LIN and DHQ+LA solutions statistically significantly reduced the total aerobic bacterial and e. coli count and meat pH (P ≤ 0.05) in comparison with control samples. We have identified a strong positive correlation between pH and total aerobic bacterial (R = 0.736, P < 0.01) and e. coli count (R = 0.818, P < 0.01). Significant differences in the total biogenic amine content were determined between DHQ+LA+LIN and DHQ+LA treated samples in air packaging (AP) (P ≤ 0.05). However, there were no significant differences (P > 0.05) in the total aerobic bacterial and e. coli count between the different packaging techniques, but VP effectively inhibited yeasts and moulds in minced beef (P ≤ 0.05).
