Pancake ready mix enriched with dehydrated squash pulp (Cucurbita moschata): formulation and shelf life.

ABSTRACT: The objective of this study was to evaluate the physicochemical, sensory and texture characteristics of pancakes which contained dehydrated squash pulp (10 and 30 g/100 g of ready mix pancake). For this, first the physicochemical characteristics as well as the thermal and functional properties of dehydrated squash pulp (DSP) were determined. Then, the stability of the pancake ready mix was evaluated, through its physical-chemical and microbiological properties, during a storage period of 3 weeks, at 25, 40 and 50 °C. Finally, shelf life was estimated by means of two predictive methods (reaction kinetics and microbiological method). Results showed that DSP presented a high dietary fiber content (30.02 g/100 g), total carotenoids (452.04 µg/g), and phenolic compounds (415?±?9.19 mg GAE/100 g), high swelling power, low solubility and emulsifying capacity. The formulation with the highest acceptance was that containing 10% dehydrated squash pulp (DSP-10), which obtained a shelf life of 5.39 weeks (28 °C) (reaction kinetics) and 33.51 weeks (microbiological method).

Project description:Winter squash fruits (Cucurbita moschata D.) are among the best sources of vitamin A precursors and constitute sources of bioactive components such as phenolic compounds and flavonoids. Approximately 70% of C. moschata seed oil is made up of unsaturated fatty acids, with high levels of monounsaturated fatty acids and components such as vitamin E and carotenoids, which represent a promising nutritional aspect in the production of this vegetable. C. moschata germplasm expresses high genetic variability, especially in Brazil. We assessed 91 C. moschata accessions, from different regions of Brazil, and maintained at the Federal University of Viçosa (UFV) Vegetable Germplasm Bank, to identify early-flowering accessions with high levels of carotenoids in the fruit pulp and high yields of seed and seed oil. Results showed that the accessions have high variability in the number and mass of seeds per fruit, number of accumulated degree-days for flowering, total carotenoid content, and fruit productivity, which allowed selection for considerable gains in these characteristics. Analysis of the correlation between these characteristics provided information that will assist in selection to improve this crop. Cluster analysis resulted in the formation of 16 groups, confirming the variability of the accessions. Per se analysis identified accessions BGH-6749, BGH-5639, and BGH-219 as those with the earliest flowering. Accessions BGH-5455A and BGH-5598A had the highest carotenoid content, with averages greater than 170.00 ?g g-1 of fresh mass. With a productivity of 0.13 t ha-1, accessions BGH-5485A, BGH-4610A, and BGH-5472A were the most promising for seed oil production. These last two accessions corresponded to those with higher seed productivity, averaging 0.58 and 0.54 t ha-1, respectively. This study confirms the high potential of this germplasm for use in breeding for promotion of earlier flowering and increase in total content of fruit pulp carotenoids and in seed and seed oil productivity.
