Blackberry fruit processing generates residues comprised of peel, seeds, and pulp that are abundant in flavonoids, colorants, and organic acids. The objective of this study was to determine the organic acids, antioxidants, and dietary fiber content of blackberry residues and compare antioxidants and dietary fiber content of a prune-based commercial product. The ABTS, DPPH, and FRAP methodologies were used for antioxidant capacity. The blackberry residues exhibited a high amount of malic acid (5706.37 mg/100 g db), phenols (4016.43 mg GAE/100 g db), and anthocyanins content (364.53 mg/100 g db) compared with the commercial product. These compounds contributed to the antioxidant capacity (by ABTS) of both products but were 20 times higher in blackberry residues. The fruit residues were able to reduce iron (by FRAP) 4.4 times compared to the prune-based product. Total dietary fiber (44.26%) and functional properties as water retention capacity (2.94 g/g), swelling capacity (5.00 mL/g), and fat absorption capacity (1.98 mL/g) of blackberry residues were significantly higher than those of the commercial sample. The results demonstrated that, due to its antioxidant compounds and functional properties, the blackberry residue can be considered a source of components with potential benefit to human health.

Seed Flour

The general aim of this study was to evaluate physicochemical properties, prebiotic activity and anticancer potential of jackfruit (Artocarpus heterophyllus) seed flour. The drying processes of jackfruit seeds were performed at 50, 60 and 70 °C in order to choose the optimal temperature for obtaining the flour based on drying time, polyphenol content and antioxidant capacity. The experimental values of the moisture ratio during jackfruit seed drying at different temperatures were obtained using Page’s equation to establish the drying time for the required moisture between 5 and 7% in the flour. The temperature of 60 °C was considered adequate for obtaining good flour and for performing its characterization. The chemical composition, total dietary fiber, functional properties and antioxidant capacity were then examined in the flour. The seed flour contains carbohydrates (73.87 g/100 g), dietary fiber (31 g/100 g), protein (14 g/100 g) and lipids (1 g/100 g). The lipid profile showed that the flour contained monounsaturated (4 g/100 g) and polyunsaturated (46 g/100 g) fatty acids. Sucrose, glucose, and fructose were found to be the predominant soluble sugars, and non-digestible oligosaccharides like 1-kestose were also found. The total polyphenol content was 2.42 mg of gallic acid/g of the sample; furthermore, the antioxidant capacity obtained by ferric reducing antioxidant power (FRAP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) was 901.45 µmol Trolox/100 g and 1607.87 µmol Trolox/100 g, respectively. The obtained flour exhibited good functional properties, such as water and oil absorption capacity, swelling power and emulsifier capacity. Additionally, this flour had a protective and preventive effect which is associated with the potential prebiotic activity in Lactobacillus casei and Bifidobacterium longum. These results demonstrate that jackfruit seed flour has good nutritional value and antioxidant and prebiotic activity, as well as potential protective effects and functional properties, making it an attractive food or ingredient in developing innovative functional products.

Citrus fruit is preferred in the choice of consumers. Kumquat (F. margarita) is an unconventional citrus of increasing consumer interest because of its exotic flavor, and its functional potential that offers health benefits to consumers. It is a fruit traditionally consumed by whole fruit (peel and pulp), giving this fruit a distinctive flavor. For this reason, this study analyzed the physical, chemical, and nutritional characteristics of kumquat (peel and pulp). The physicochemical analysis was performed according to the Adolfo Lutz Institute. Analysis of moisture, ashes, macronutrients, and total dietary fiber was carried out according to AOAC. Minerals were analyzed by inductively coupled plasma optical emission spectrometry. Vitamins C and E, carotenoids and flavonoids were analyzed by HPLC. Phenolic compounds (Folin-Ciocalteu) and antioxidant capacity (DPPH) were determined by spectrophotometry. The kumquat had low pH, soluble solids content and low caloric value. It was a source of dietary fiber, minerals (K, Ca, P, Mg) and carotenoids; the most expressive was α-carotene (661.81 μg 100 g−1). The ascorbic acid concentration was 2326.24 μg 100 g−1. α-tocopherol (569.00 μg 100 g−1) was the most expressive component of vitamin E. There was a presence of apigenin and eriodictyol. The fruit (peel and pulp) has a high concentration of total phenolic compounds (98.55 ± 1.93 mg GAE 100 g−1) and good antioxidant capacity (62%) was found. Kumquat is a good source of fiber and vitamin A, and due to its antioxidant capacity and the presence of other essential and beneficial nutrients for a diet, consumption of kumquat can be suggested to complement the diet. This fruit is a viable food alternative, and its consumption should be encouraged, contributing a source of income, sovereignty, and food security.

Purple Sweet Potato

Purple sweet potato is one type of tuber that is rich in carbohydrates in the form of starch and fiber. It also contains purple anthocyanin pigments. In this research, purple sweet potato was processed into flour and starch. Starch processing solid waste can be utilized by processing it into fiber flour. Purple sweet potato flour and fiber were then used as the basis for making biscuits at a ratio of 75: 25 and compared to biscuits made from 100% purple sweet potato flour and wheat flour. The resulting biscuits were then analyzed for their chemical characteristics. The results showed that the ratio of flour gave a very significantly different effect on the value of water content, total dietary fiber content, insoluble dietary fiber content and % nutritional adequacy rate of food fiber, and had no significant effect on the value of ash content, protein content, fat content, content carbohydrates, total flavonoids, insoluble dietary fiber content, calorie intake and fulfillment of daily energy adequacy.

In this work we evaluated the variability in fiber content and physical and chemical parameters of byproducts from orange juice extraction. Five different treatments and two drying methods were evaluated. The results indicate that drying by lyophilization was better than that drying in an oven. The pH ranged from approximately 3.47 to 3.96. The variation in moisture values was 9.22% ± 0.02 to 18.48 ± 0.52%. The total dietary fiber content in the resulting flours ranged from 42.44% to 62.74%. The soluble and insoluble dietary fiber contents differed among the samples, ranging from 5.04% to 19.95% for the first fiber type, and 23.96% to 57.70% for the second. In conclusion, three treatments, associated with freeze-drying, showed promising results in the development of fiber-rich product. However, some modifications are needed, as well as further analysis, to guarantee the benefits of these products for human health. This study contributes to the possible application of industrial byproducts.

Confectionery Products

Resistant starch (RS) is a part of insoluble dietary fiber, and it could be recognized as a functional food ingredient in some types of confectionery products that lack dietary fiber. Unlike dark and milk chocolate, white chocolate does not contain fat-free cocoa solids rich in dietary fiber. In the present study, 5%, 10%, and 15% of white chocolate were substituted with RS in order to improve the nutritional value of enriched white chocolate. The influence of RS on rheological, textural, and thermal properties of the chocolate fat phase was firstly investigated, and then further influence on physical properties, dietary fiber content, and sensory characteristics of enriched white chocolates were investigated. The obtained results showed that enriched chocolates had increased content of total dietary fiber and reduced total fats and protein content in accordance with the added amount of RS. At the same time, RS increased viscosity and reduced the hardness and volume mean diameter in enriched chocolates in accordance with the added amount. RS improved the nutritional composition of white chocolate by increasing the content of dietary fiber. At the same time, RS did not impair the color and sensory characteristics of enriched white chocolates.
