Complex Carbohydrates

The extraction of white jack bean (Canavalia ensiformis) protein isolate frequently leaves a lot of precipitates containing complex carbohydrates such as starch, dietary fiber, and resistant starch. Repeated autoclaving – cooling cycles can increase the content of soluble fiber and resistant starch. The aim of this study was to determine changes of dietary fiber and resistant starch content of complex carbohydrates of white jack bean during autoclaving-cooling cycles and characterization of its chemical composition and functional properties. The experiment was conducted by applying the autoclaving process at 121oC for 15 minutes followed by cooling at 4oC for 24 hours up to 5 times. Sample was taken from each cycle of autoclaving – cooling. The best treatment was the sample with the highest total soluble fiber and resistant starch content. The best sample will be determined its chemical composition and functional properties. This study used a one-way analysis of variance to subject the data according to Completely Randomized Design. Duncan’s Multiple Range Test was applied to determine significant differences among 5 treatment means at the 5% significance level. The highest value of total soluble fiber and resistant starch content was obtained from autoclaving-cooling cycles of 3 times. The treatment increased the soluble fiber and resistant starch by 14.37% and 18.34%, respectively, but decreased 14.41% insoluble fiber. The complex carbohydrates of white jack bean treated with autoclaving-cooling cycles of 3 times had chemical composition: 10.68% moisture content, 0.92% ash content, 0.02% fat content, 1.85% protein content, 97.20% carbohydrate content (by difference), 68.42% starch content, and 14.90 ppm HCN. It also had functional properties: 351.67% WHC, 115.67% OHC, 775.33% SC, 84.63 meq/kg CEC. The conclusion was the white jack bean carbohydrate complex treated with 3 times autoclaving-cooling cycles was the best treatment to produce the highest value of total soluble fiber and resistant starch content. We suggest to examine another autoclaving temperature and cooling time to compare the result.

The addition of brewer’s spent grain (BSG), sugar beet pulp (SBP) and apple pomace (AP), on the nutritional properties of directly expanded snack products based on corn grits was investigated. Snack products were produced in a laboratory single screw extruder with the addition of 5, 10 and 15% d. m. of these by-products in corn grits. Chemical composition, total phenolic content, antioxidant activity, dietary fiber, resistant starch, starch damage and pasting properties of the mixtures and extruded samples were determined. Extrusion process and by-product additions had a significant effect on the proximate chemical composition. All three by-products increased contents of both soluble and insoluble dietary fiber, while the extrusion caused a reduction of insoluble fiber and increase of soluble fiber. After the extrusion process starch damage and antioxidant activity increased, while resistant starch content and total polyphenol content decreased. According to obtained results, it can be concluded that the investigated by-products can be used in the production of nutritionally more valuable corn snacks.

There is a growing interest in food matrixes for the use of flour from unpeeled green banana in order to reduce waste in the production chain. Considering this, the present paper aims to studying the application of unpeeled green banana flour in the cold process performed to obtain bake stable fruit filling. The unpeeled green banana pulp (Musa Cavendishii) was dried using a single rotating drum, thus obtaining the flour. The dried flour was then analyzed for its chemical composition, amylose and resistant starch content, water absorption capacity and pasting properties. The drying reduced the amount of resistant starch and produced pregelatinized starch. The obtained flour showed physical and nutritional characteristics which enabled the development of the filling formula by using a central composite design combining levels -1 and +1, two axial points (± α), two central points, and chemical composition, water activity, Brix, and texture as response variables. The amount defined by central-composite design of unpeeled green banana flour, modified starches and other ingredients resulted in an elastic, viscous, bake stable fruit filling.

Several aquatic macrophytes such as Colocasia esculenta, Eleocharis dulcis, Nelumbo nucifera, Sagittaria sagittifolia, Trapa bispinosa, and Typha angustifolia possessed carbohydrate mainly in their storage and reproductive parts. Starch morphology, total starch, and amylose content of these six freshwater plant species were determined. Their functional properties, i.e., starch crystallinity, thermal properties, and rheological behaviour were assessed. Large starch granules were in N. nucifera rhizome (>15 μm), medium-sized was N. nucifera seed (8-18 μm), while the rest of the starches were small starch granules (<8 μm). Shapes of the starch granules varied from oval and irregular with centric hilum to elongated granules with the eccentric hilum. Eleocharis dulcis corm starch had significantly higher total starch content (90.87%), followed by corms of C. esculenta (82.35%) and S. sagittifolia (71.71%). Nelumbo nucifera seed starch had significantly higher amylose content (71.45%), followed by T. angustifolia pollen (36.47%). In comparison, the waxy starch was in N. nucifera rhizome (7.63%), T. bispinosa seed (8.83%), C. esculenta corm (10.61%), and T. angustifolia rhizome (13.51%). Higher resistant starch was observed mostly in rhizomes of N. nucifera (39.34%)>T. angustifolia (37.19%) and corm parts of E. dulcis (37.41%)>S. sagittifolia (35.09%) compared to seed and pollen starches. The XRD profiles of macrophytes starches displayed in all the corms and N. nucifera seed had A-type crystallinity. The T. bispinosa seed had CA-type, whereas the rest of the starches exhibited CB-type crystallinity. Waxy starches of C. esculenta corm had higher relative crystallinity (36.91%) and viscosity (46.2 mPa s) than regular starches. Based on thermal properties, high-amylose of N. nucifera seed and T. angustifolia pollen resulted in higher gelatinization enthalpy (19.93 and 18.66 J g-1, respectively). Starch properties showed equally good potential as commercial starches in starch-based food production based on their starch properties and functionality.

Grape Peel

Capitalization of winery by-products has received high interest among scientists, producers and consumers concerned with healthy diet and environment protection. Grape peels are rich in fiber and polyphenols and can be used as ingredients in pasta matrix in order to increase the nutritional and functional value of such a staple food. The aim of this paper was to investigate the effects of grape peel flour added in various amounts (1–6%) to common wheat pasta dough viscoelasticity and texture and on pasta chemical composition, color, cooking behavior and texture, revealing at the same time the relations between characteristics. Grape peel flour induced the increase of the elastic (G′) and viscous (G″) moduli, dough hardness, springiness, cohesiveness, pasta crude ash, crude fat, crude fiber, total polyphenols and resistant starch contents, pasta water absorption, cooking loss and breaking force as the addition level was higher and compared to the control. On the other hand, dough resilience, pasta luminosity, chewiness and firmness decreased as the amount of grape peel flour raised. Significant correlations (p < 0.05) were obtained between the chemical composition and color parameters, while crude fiber, protein and fat were correlated with dough and pasta texture, total polyphenols with resistant starch content, cooking loss with crude fiber and dough textural parameters. The obtained results underlined the opportunity to use a valuable byproduct such as grape peels in novel pasta formulations, being helpful for processors to extend the product variety and to optimize the processes in order to better satisfy consumer’s demand for functional foods.

Abstract Human interest in ancient grains replacing traditional carbohydrate sources has reached the pet food market; however, chemical composition of these grains and their digestive properties in the canine model, specifically the fermentative characteristics, have not been established. Five ancient grain varieties were analyzed: amaranth (AM), white proso millet (WPM), oat groats (OG), quinoa (QU), and red millet (RM). Cellulose (CEL) was used as a negative control, and beet pulp (BP) was used as a positive control. Substrates were analyzed for macronutrient composition as well as free and hydrolyzed sugar profiles in addition to their in vitro fermentative characteristics. Substrates were allocated into 2 sets to allow for quantification of pH, short-chain fatty acids, and branched-chain fatty acids, as well as gas volume and composition. Samples were digested for 6 and 18 h with pepsin and pancreatin, respectively, prior to inoculation with fecal bacteria for 0, 3, 6, 9, or 12 h. Detectable levels of cereal β-glucans were observed solely in OG (3.5%), with all other substrate containing &lt;0.35% cereal β-glucans. All test substrates had fairly similar macronutrient and starch profiles with the exception of RM that contained the highest resistant starch content (2.4%), with all other test substrates containing &lt;0.5% resistant starch. However, the analyzed pseudocereals, AM and QU, had the highest concentrations of free glucose while the minor cereal grains, WPM, OG, and RM, contained the highest concentrations of hydrolyzed glucose. All test substrates had propionate production values similar or greater than BP after 3, 6, 9, and 12 h of fermentation, and similar or greater butyrate production values than BP after 6, 9, and 12 h. All substrates had greater (P &lt; 0.05) changes in pH than CEL after 6, 9, and 12 h, with AM, WPM, OG, and RM having greater (P &lt; 0.05) changes in pH than BP after 9 and 12 h. These data suggest select ancient grains have similar fermentation characteristics as BP, a moderately fermentable fiber considered the gold standard in terms of fiber sources in the pet food market today, and that OG and AM may be more fermentable during longer fermentation periods.
