Background. Legumes are usually consumed when physiologically mature, as dry seeds, however, flageolet beans seeds are also consumed immature. They are harvested when dry matter content is about 40%, pods are filled, grown, seeds succulent, showing green or light green colour and do not require lengthy thermal processing when prepared for consumption. Material and methods. The aim of this study was to evaluate vitamin C content in immature seeds of five bean cultivars harvested when dry matter content was 40%. The analysis included raw, blanched and cooked fresh seeds and three products prepared for consumption after 0, 4, 8 and 12 months of storage: frozen products obtained using the traditional method (blanching-freezing-frozen storage-cooking), frozen products obtained using a modified method (cooking-freezing-frozen storage-thawing and heating in a microwave oven), a ready-to-eat product to consumption at ambient temperature, and canned products obtained by sterilization. Results. The application of technological processes, frozen and sterilized products storage, and the preparation for consumption had a cumulative effect in retention vitamin C content on final products. Conclusion. Comparing frozen seeds obtained by modified method with seeds treated by traditional method, generally, this one could retain more vitamin C. Canned seeds retained significantly less vitamin C than other frozen products.
