The banana fruit (yellow peel with brown flecks) were used for producing canned banana desserts. In first part of the investigation 17 samples were considered for various pre-treatment methods of bananas. Sliced bananas were blanched (at 80-82°C for 120 s) or soaked (24 h) in sugar syrup (10%, 30% and 50%) with L-ascorbic (0.2%) or citric (0.8-1.0%) acids, acid sodium sulphite (0.2%) and calcium chloride (1%). On the basis of the first part of the experiment, the best combinations were selected for further investigation. In the second part of the experiment the determinations concerned the effect of technological measures on the level of physico-chemical indices and on the sensorial traits of the bananas. In this part of investigetion all the applied methods of pre-treatment of banana slices ensure the production of good quality canned products. The applied calcium chloride had the most favourable effect, improving the hardness and sensory quality.

Background. Legume seeds, including beans, are a good source of mineral constituents. The level of these compounds depends among other factors, on the species, cultivar and the methods of processing applied. However, there are no studies in the literature which deal with the content of mineral constituents in physiologically immature bean seeds. Material and methods. The aim of this study was to evaluate the retention of ash and 13 mineral constituents in immature seeds of three bean cultivars. The investigation included raw, blanched and cooked seeds and three products prepared for consumption after 12-month storage: a frozen product obtained using the traditional method (blanchingfreezing-frozen storage-cooking); a frozen product obtained using the modified method (cooking-freezing-frozen storage-defrosting and heating in a microwave oven); and a sterilized canned product. Results. The application of technological processes; the storage of frozen and sterilized products; and the preparation of frozen products for consumption had an effect on minerals content in finished products. The frozen product obtained using the modified method retained greater amounts of the investigated elements (apart from calcium, lead and cadmium) than the traditional frozen product. Canned bean seeds retained less ash, phosphorus, potassium, calcium, magnesium, sodium and iron than the products of the two ways of freezing, while the retention of the remaining constituents depended on the cultivar. Conclusions. Modified method of freezing of immature bean seeds resulted in greater retention of the investigated components in products prepared for consumption than the traditional method of freezing or canning.

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.
