Abstract
Japanese quince (Chaenomeles japonica) is one of the most underutilized plant species that have high nutrient value and a positive impact on human health. Due to the high content of bio-compounds, such as phenols, vitamin C, triterpenes, fibers, essential amino acids, and microelements, the fruits, leaves, and seeds are excellent raw materials for functional food production. In addition, their biochemical composition and anti-inflammatory, anticancer, and antibacterial properties expanded their uses in the pharmaceutical field. Moreover, it was demonstrated that quince waste after industrial processing is still valuable and suitable for remanufacturing and developing innovative high value-added products, which can provide economic and ecological benefits. This chapter presents the biochemical composition and possible application of C. japonica cultivars Rasa, Darius, and Rondo. The optimization of processing and extraction parameters was evaluated to increase the extraction efficiency of biologically active compounds and to reduce the extraction time and cost of electricity and environmentally harmful solvents. Moreover, the detailed nutritional and pharmacological value of Japanese quince can help for more selective plant organs application. Our study revealed that cultivars Rasa, Darius, and Rondo are very valuable with many new options for utilization, including food, cosmetic, and pharmaceutical industries.
