Galactinol synthase (GolS) catalyzes the formation of galactinol, which will produce raffinose oligosaccharides (RFOs). Expression of GolS during water deficit stress has been reported, probable due to the function of RFOs as osmoprotectant. Three galactinol synthase isoforms (CaGolS1, 2 and 3) were identified from the Coffee Genome Brazilian Project database (http://www.lge.ibi.unicamp.br/cafe/). The isoforms have similar length to others GolS genes. Northern blot analysis showed an increased in CaGolS1 transcripts in coffee plants under water shortage when compared to plants in well-watered conditions. Transcripts of CaGolS1 were specifically found on leaves and not in other tissues. |

Orange-fleshed sweet potato (OFSP) is well known to have high ?-carotene content and sunflower oil, as a source of polyunsaturated fatty acids and vitamin E. The combination of these raw materials in baked goods can reduce health risks of hypovitaminosis A, especially in at-risk groups. The aim of this study was to develop cakes with different OFSP:sunflower oil proportions and to evaluate the retention of total carotenoids (TC) and all-trans ?-carotene (ATBC) during processing and storage. Cakes with 40:11 g/100 g (T1), 40:3 g/100 g (T2) and 35.86:7 g/100 g (T5) (OFSP:sunflower oil proportions) were analyzed by spectrophotometry and high-performance liquid chromatography (HPLC) to evaluate the retention of TC and ATBC after processing and four days of storage. The combination of at least 35.86g/100g of OFSP and 7.00g/100g of sunflower oil showed greater retention of TC and ATBC during processing and maintenaince during storage. The presence of more than 3 g/100 g of sunflower oil is essential for the maintenance of TC and ATBC (suggestion: 7 g/100 g or more) in cakes containing OFSP. |
