Abstract: In the food industry, quince seeds are discarded as waste in the production process. Their use therefore creates added value and opens up the possibility of using no-waste processing technologies. Three types of waste were investigated: after juicing, after the manufacture of puree and syrup. The results showed that the yield of quince seeds (Chaenomeles japonica (Thunb.) Lindl. ex Spach from waste left after different production methods varies from 29.8 to 38.3 %. The cold pressed oil yield ranges from 4.9±0.03 to 7.1±0.06 %. The oil yield obtained by Soxhlet extraction varies from 14.6±0.64 to 17.3±0.9 %. Unsaturated fatty acid, especially polyunsaturated fatty acid is predominant in quince seed oil. The linoleic acid content of the quince seed oils was between 47.12 % and 58.49 % of the total fatty acids. The fatty acid composition of oils from post-industrial waste is more appropriate in the skin care industry than in the food industry because of the high ratio of omega-6/omega-3 and high linoleic acid content
