Micro-isolation of PCR-ready from fresh and dried legumes seeds and food products containing legumes (hummus) was tested. For optimization process magnetic microparticles PGMAox was used. Optimum weight plants and food material was 200 mg. For isolation of DNA from fresh legumes, mixture containing 500 L of CTAB extraction buffer, 1 L -mercaptoethanol and 500 L chloroform-octanol was used. For isolation of DNA from dried legumes seeds and food products volume of CTAB extraction buffer was increased to 1 000 L. To achieve higher purity of DNA some prepared homogenates was precipitate by isopropylalcohol. The optimized process of DNA isolation was used to prepare a homogenate from food products which DNA was isolated by different types of magnetic carriers. For comparison, non-porous magnetic carriers poly(glycidyl methacrylate) PGMAox, poly(2-hydroxyethyl methacrylate-co-glycidyl methacrylate) P(HEMA-co-GMA)ox covered by carboxyl groups and porous fully crosslinked microparticles poly(styrene-co-divinylbenzene) HPS-B-M-22-NH2, magnetic porous glass MPG and nanoparticles of iron oxides covered by poly(L-lysine) PLL were used. In average the highest concentration and the best purity of DNA was isolated by magnetic carriers P(HEMA-co-GMA)ox a PGMAox.
