ABSTRACT Resistant starches (RS) were prepared by phosphorylation of wheat, waxy corn, high‐amylose oat, rice, tapioca, mung bean, banana, and potato in aqueous slurry (≈33% starch solids, w/w) with 1–19% (starch basis) a 99:1 (w/w) mixture sodium trimetaphosphate (STMP) tripolyphosphate (STPP) at pH 10.5–12.3 25–70°C for 0.5–24 hr sulfate or chloride 0–20% basis). The RS 4 products contain ≤100% dietary fiber when assayed the total method Association Official Analytical Chemists (AOAC). In...
Abstract Poly(lactic acid) (PLA) is a biodegradable polymer, but its applications are limited by high cost. Blending granular starch with PLA reduces the cost, blend has poor strength properties. In this study, 55/45 (w/w) mixture of (weight‐average molecular weight = 120,000 Da) and dried wheat was blended thermally in an intensive mixer or without low level methylenediphenyl diisocyanate (MDI). Blends MDI had enhanced mechanical properties that could be explained situ formation block...
Starches were isolated from grains of waxy, heterowaxy, and normal sorghum. To study the relationship between starch structure functionality guide applications these starches, amylose content, amylopectin chain-length distributions, gelatinization retrogradation, pasting properties, dynamic rheological in vitro enzyme digestion raw starches analyzed. Heterowaxy sorghum had intermediate properties. Stress relaxation was a useful indicator cooked cohesiveness. Cooked heterowaxy (10% solids)...
Abstract Poly(lactic acid) (PLA) and wheat starch are biodegradable polymers derived from renewable sources. A previous study showed that thermally blending PLA in the presence of methylenediphenyl diisocyanate (MDI) enhanced mechanical properties blends. In this work, blends with various levels MDI were hot mixed at 180°C then hot‐pressure molded 175°C to form test specimens. The characterized for properties, fracture microstructure, water absorption. Pure had a tensile strength 62.7 MPa...
ABSTRACT Novel browning inhibitors were evaluated in raw apple juice and on the cut surface of plugs, using quantitative measurements color changes during storage to assess treatment effectiveness. Ascorbic acid‐2‐phosphate (AAP) ‐triphosphate (AATP) showed promise for surfaces but ineffective juice. acid‐6‐fatty acid esters anti‐browning activity Cinnamate benzoate inhibited induced when applied surfaces. Combinations β‐cyclodextrin with ascorbic (AA), AAP or ascorbyl palmitate effective...
Abstract Physical properties of blown films (25‐60‐μm thickness) from compounded mixtures linear low‐density polyethylene (LLDPE) and starch were investigated. As content increased, tensile strength, percent elongation, light transmittance decreased film thickness increased. Among the tested films, small‐particle corn (2‐μm average diameter) had highest elongation rate yield strength (560%, 3.15 kg/mm 2 , 1.07 respectively, at 15% content). Potato (35‐μm lowest values (508%, 1.52 0.55...
ABSTRACT Starch was isolated from flour of four wheats representing hard red winter (Karl), spring (Gunner), durum (Belfield 3), and spelt (WK 86035‐8) wheat classes. Digital image analysis (IA) coupled with light microscopy used to determine starch size distributions where the volume granules calculated as spherical particles or oblate spheroids. were classified into three ranges: A‐type (> 15 μm), B‐type (5–15 C‐type (<5 μm). An error noted in using digital because perimeter some...
ABSTRACT The goal of this research is to understand the key factors affecting ethanol production from grain sorghum. Seventy genotypes and elite hybrids with a range chemical compositions physical properties selected ≈1,200 sorghum lines were evaluated for used study relationships composition, structure, features that affect yield fermentation efficiency. Variations 22% in 9% efficiency observed among 70 samples. Genotypes high low conversion efficiencies associated attributes may be...
ABSTRACT The effects of amylose, protein, and fiber contents on ethanol yields were evaluated using artificially formulated media made from commercial corn starches with different fiber, as well cereal sources including corn, sorghum, wheat amylose contents. Second‐order response‐surface regression models used to study the interactions yield conversion efficiency. results showed that content had a significant ( P < 0.001) effect No protein production was observed. Fiber did not show...
The purpose of this study was to determine whether different types resistant starch (RS) elicited glycemic responses. Eleven healthy subjects consumed solutions containing 30 g either dextrose (DEX), type 2 (RS2), or cross-linked wheat 4 () on three separate occasions, which were assigned randomly. Finger stick blood samples collected before and over the following two hours measured for glucose. incremental area under curve (iAUC) glucose response calculated all trials. significantly...
