Due to increasing consumer demand for healthy foods, attempts are being made to improve their nutritional value. Thus, there is a necessity to develop food bars enriched with dietary fiber and palatable nutritional components. The aim of this study was to evaluate the shelf life of food bars, prepared with different proportions of marolo pulp flour (20,30,40, and 50% replacement of oatmeal) for six-month storage, through nutritional and physical analysis, as well as sensory acceptance. The total dietary fiber content showed an average of 7.1 g⋅100 g −1 . There was a significant increase in antioxidant activity, vitamin C, and total carotenoids content according to increasing concentration of marolo pulp flour in the food bars. In sensory evaluation, the food bar with addition of 50% marolo pulp flour showed higher averages for all evaluated attributes and was the favorite by the evaluators. IntroductionBrazil is a country with enormous biodiversity, and Cerrado is its second largest biome, with many native species that produce fruits with excellent nutritional, sensorial, and functional potential. However, most of these fruits remain poorly explored scientifically [1].The marolo (Annona crassiflora Mart.) is a typical fruit of the Brazilian Cerrado and is among the 20 most common species in regional food [2]. da Silva et al. of dietary fiber, and 1830.6 mg⋅kg −1 vitamin C. The fiber constituting the edible portion of plants is resistant to digestion and absorption in the small intestine, playing an important role in gastric emptying and control of peristalsis. It fulfills an important role in nutrition, promoting beneficial effects for health and may delay the onset of chronic diseases and improving the quality of life [4].Due to the increasing consumer demand for healthy food, attempts are being made to improve the nutritional value of foods such as cereal bars [5]. The consumption of such food has grown due to its convenience, with the change in people's lifestyle.The expanding market for cereal bars and foods recognized as healthy products is leading the industry to diversify the variety of flavors and attributes, such as products enriched with nutrients; products developed for a specific group of people or with new features that benefit health [6,7].Given the above, we see the need to develop food bars enriched with dietary fiber, nutritional components, and palatable taste. Therefore, the aim of this study was to evaluate the shelf life of food bars, made with marolo pulp flour in different concentrations, during the period of 6 months,
The aim of this study was to evaluate the physicochemical changes and the antioxidant potential of caja-manga (Spondias mombin L.) fruit during its physiological development. The cycle comprised a period of 260 days after anthesis (DAA), set when the fruits were yellow-orange colored and easily detached from the pads. The results showed that the fruits had simple sigmoid type of growth pattern, with significant increase in mass, and longitudinal and transverse diameters up to 220 DAA. A decrease in total pectins and an increase in soluble pectins, lower acidity and chlorophyll levels, and masking of carotenoids exposure was observed, leading to color changes and softening in fruit. Significant changes were observed from 200 to 220 DAA, which may be the period that fruit has reached its maturity, emphasizing phenolic, vitamin C and antioxidant activity.
The flour from the pulp of marolo (Annona crassiflora Mart.) is an important source of fiber, however, its use as a food ingredient requires investigation as to its functionality. Thus, this work aimed to evaluate the physical, chemical, nutritional and technological functional properties of the flour obtained from the pulp of marolo, thus verifying its potential application in food products. The analyzes performed on the flour were proximal composition, mineral composition, vitamin C content, total carotenoids, beta-carotene, antioxidant activity and technological functional properties. The flour presented considerable amounts of fibers, especially the insoluble fraction, being 25.47 g.100g-1, 8.57 g.100g-1 for soluble dietary fiber and 34.04 g.100g-1 for total dietary fiber. . The levels of vitamin C and total carotenoids, observed in the flour of the pulp of marolo, were 173.77 mg.100g-1, 0.56 mg.100g-1 and 0.08 mg.100g-1, respectively. The minerals that showed the highest concentration in the pulp flour were phosphorus (1768.53 mg.kg-1) and calcium (1512.73 mg.kg-1). The antioxidant activity was more effective when performed in aqueous extraction. The flour has shown to have important technological functional properties, such as solubility in water and the ability to form emulsion. Therefore, marolo pulp flour has the potential to be commercialized and used in food products in order to improve and enrich its nutritional and technological qualities.
