This study was to investigate the proximate composition, total antioxidant activity and functional properties of mango (Mangifera indica L. var Perlis Sunshine) peel flour. The proximate analysis (g/100g) was determined as carbohydrate (84.6%), fat (4.0%), total protein (1.6%), total dietary fiber (54.2%), soluble dietary fiber, (SDF) (20.0%), insoluble dietary fiber, (IDF) (34.2%) and calories (381 kcal/100g). The studies also indicated that mango peel flour from Perlis Sunshine varieties can neutralized DPPH radicals by neutralized 80.00% of free radicals, thus contained about 22.4 mg/g of total flavonoids contents (TFC) values and 21.7 mg/g of total phenolic contents (TPC) values. Functional properties of between wheat flour and mango peel flour concentration were analyzed in terms of water and oil holding capacity, foaming capacity and stability, swelling capacity, emulsion activity and stability, and bulk density, respectively. The present data may provide guideline for food formulation based on Perlis Sunshine mango peel flour.

The objective of the recent study was to evaluate the effect of banana pseudostem flour (EBP) to the organoleptic properties, levels of dietary fiber, resistant starch and antioxidants of canna starch-based food bar. The research design was true experimental in the form of completely randomized design with 6 treatments using canna starch: banana pseudostem flour. The six treatments were 100:0, 95:5, 90:10, 85:15, 80:20, and 75:25 ratio. The best food bar was determined by scoring through organoleptic test, content of soluble dietary fiber and antioxidants. Food bars processed with mixture of banana pseudostem flour proportion 85:15 was selected as the best food bar with a score of color attribute 3.12±0.08, aroma 3.00±0.06, flavor 3.04±0.18, texture 3.16±0.12, soluble dietary fiber content 0.83±0.07% db, insoluble dietary fibers of 6.75±0.14% db, total dietary fiber 7.58±0.13% db, resistant starch 6.54±0.24% db, total phenolic 105.75±0.64 mg/100 g, antioxidant activity 6.97±0.77% RSA, color brightness (L*) 52.52±0.60 and hardness level 5.08±1.95 N. The substitution of banana pseudostem flour on the canna starch-based food bar increased level of soluble dietary fiber 0.83%, total dietary fiber 4.81%, resistant starch 2.89%, total phenolic 43.01 mg/100 g and antioxidant activity 3.98% RSA as well as sensory panelists preferred.

The Jerusalem artichoke (Helianthus tuberosus) tuber is a vegetable with a low caloric value and a high content of inulin, vitamins and minerals. The purpose of this study was to determine the physicochemical properties of Jerusalem artichoke powder (JA powder). The results indicated that moisture, ash, crude fiber, protein, lipid and carbohydrate contents were 6.71, 3.54, 2.83, 7.58, 0.28 and 79.04%, respectively. The Jerusalem artichoke stored carbohydrates in the form of inulin instead of starch. Total dietary fiber (TDF), soluble dietary fiber (SDF) and insoluble dietary fiber (IDF) of JA powder were 53.11, 40.07 and 13.04%, respectively. Total sugar, total phenolic compound (TPC) and antioxidant activity by DPPH of JA powder were 0.92 mg fructose/g sample, 6.58 mg GAE/g sample and 93.74 mg TEAC/g sample, respectively. Furthermore, this research reported the design of experimental for optimizing JA powder on the quality of glass noodles using three independent variables: JA powder concentration (0-3%), alginate concentration (1.5-2.5%) and calcium concentration (1-3%). The optimum condition for the glass noodles was 3% JA powder, 2% alginate and 3% calcium. This optimization revealed that glass noodles had more fiber and sugar, as well as good hardness, cohesiveness, springiness and gumminess. The microstructure of glass noodles addition with JA powder was smaller porosity than glass noodles without JA powder (commercially glass noodle).

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.

Effects of particles size of dietary fiber powder on the physico-chemical properties and antioxidant activity of corncob were investigated. Corncob was grounded in a regularly mill and grinding characteristics and the particles size were evaluated by particle size analyzer (PSA) using laser diffraction method and Fourier transform infrared (FTIR). The results showed that the insoluble dietary fiber (IDF) powder from corncob had the highest crude fiber content (32.31%) and carbohydrates (55.07%). Spectral analysis shows that the IDF matrix structure does not change after grinding and has three characteristics of absorption spectra at 3433-3425 cm-1 (O-H); 2920 cm-1 (C-H) and 1635 cm-1 (aromatic) in presence of the special structures of polysaccharide and lignin compounds. Particle size analyzer (PSA) results showed that the size of IDF 200 mesh and 80 mesh powder were 63.13 and 260.89 μm, respectively. The insoluble dietary fiber (IDF) significantly shows a decrease in dietary fiber content in line with the reduction in particle size. The IDF powder with a particle size of 63.13 μm showed that highest total phenolic content accompanied with the best antioxidant activity through all antioxidant assays (p < 0.05). This study concluded that the IDF micro-powder particle size exerted influence on physico-chemical properties, dietary fiber, total phenolic and antioxidant activity.

<strong><em>Flavanoid, steroid, and terpenoid contents of 20 Manokwari medicinal plants were analyzed.  The antioxidant activity, total phenolic contents and antitumor activity of 20 Manokwari medicinal plants were also evaluated. The result shows that 83% positif to flavanoid test, 59% positif to terpenoid test and only 25% positif steroid. Antioxidant activity and total phenolic contents evaluated using Ferric Thiocianate (FTC) and Folin-Ciocalteu methods respectively. Antioxidant activity and total phenolic contents of medicinal plants were extracted by the traditional method, boiling in water and also in 80% methanol. Twenty plants evaluated in both exstracts have significantly varies of antioxidant activities and phenolic contents,  A significant and linier correlation coefficient between the antioxidant activity and the total phenolic content was found in both aqueous (R<sup>2</sup>= 0,77) and methanol (R<sup>2</sup> = 0,85). Antitumor activity was tested using cell maurine P-388 and only 2 of medicinal plants are active to inhibit cell maurine P-388. Comparing extraction efficiency of the two methods, the methanol extracted phenolic compounds more efficiently, and antioxidant activity of the extract was higher.</em></strong>
