Reduce Blood Glucose Level

Prevalence of diabetes mellitus (DM) in Indonesia increased by 1.6% from 2013 to 2018. The reason was that people’s diets tend to comsume fast food that contains high carbohydrate and fat but low fiber. Beside that, increased prevalence of DM also caused by the accumulation of oxidative stress. Therefore, it is necessary to increase the intake of fiber and antioxidants that can reduce blood glucose level in people with DM. Examples of foods that contain fiber and antioxidant are limau orange peel pectin and yellow pumpkin. These foods can be made into limau orange peel pudding with addition of yellow pumpkin. The research aims to identify dietary fiber content, antioxidant activity and physical properties of limau orange peel pudding with addition of yellow pumpkin. Experimental method with descriptive analysis applied for the method. The results of chemical properties analysis were dietary fiber content ranged from 1.24 - 2.08% and antioxidant activity IC50 ranged from 3.79 - 9.34% b/v. The results of physical properties analysis were gel strength ranged from 218.40 - 245.33 gf and syneresis at 24 hours ranged from 9.09 - 21.59%; at 48 hours ranged from 15.91 - 28.41% and at 72 hours ranged from 21.59 - 29.55%. It concluded that the more addition of yellow pumpkin causes antioxidant activity and syneresis increases but dietary fiber content decreases. The highest antioxidant activity and syneresis were in F3 pudding while the highest dietary food content was in F1 pudding.

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.

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.

Abstract Grape pomace is a rich source of dietary fibers and phenolic compounds; it has been added to bakery products to enhance their dietary fiber content and antioxidant activity. Nevertheless, the Insoluble Dietary Fiber (IDF) content of grape pomace is significantly higher than the Soluble Dietary Fiber (SDF) content, the IDF/SDF ratio of bakery products was much higher than the recommended value of 3:1 from the dietetic associations. In this research, grape pomace was treated with cellulase preparation to partially convert IDF to SDF. The appropriate conditions of the cellulolytic treatment were as follows: initial moisture content of grape pomace of 7.5 g water/g dry basis, cellulase concentration of 6 U/g dry basis and treatment time of 1 h. Under these conditions, the SDF content increased by 20% and the IDF/SDF ratio decreased by 23.2%. Then, the enzyme-treated grape pomace (ETGP) and untreated grape pomace (UGPM) were separately mixed with wheat flour for cookie formulation; the grape pomace ratio was 20% of the composite flour weight. The use of ETGP or UTGP significantly improved the content of total, insoluble and soluble dietary fiber, total phenolics, anthocyanin of cookies as well as their antioxidant activity measured by DPPH and FRAP assays. Cookies supplemented with ETGP or UTGP had increased hardness and reduced brightness. The enzymatic treatment of grape pomace did not affect the total dietary fiber and antioxidant activity of cookies; however, their IDF/SDF ratio decreased to 12% and the value of 3.7 was close to the recommended ratio from the dietetic associations. Furthermore, the preference scores of ETGP added cookies and UTGP added cookies were higher than that of the control cookies without grape pomace addition.
