crosslinked poly(acrylic acid)s were prepared using two types of crosslinker by precipitation polymerization method in a binary organic solvent. n,n’-methylenebisacrylamide (mba) and polyethylene glycol dimethacrylate (pegdma-330) were used as low-molecular weight and long-chain crosslinkers, respectively. the effect of various types of crosslinkers on polymer characteristics (i.e., gel content...

the effect of xanthan and qodume shirazi seed gum on fresh bread quality and its influence on dough rheology were studied. incorporation of 0.3 to 1% of these two gums was investigated to evaluate its effect on the mixing tolerance index (mti), dough development time (ddt), gelatinization temperature (gt), viscosity, dough stability and quality of wheat flour. addition of xanthan and qodume shi...

There is an association between obesity and rheological blood behavior [2, 4–7]. In this sense we have read with interest the recently published article by Brun et al. [1] in this journal. The authors evaluate, in a population of 430 subjects, the relationship between abdominal obesity and body mass index (BMI) with blood viscosity, and conclude that both anthropometric parameters are associate...

Late maturity α-amylase (LMA) and preharvest sprouting (PHS) are genetic defects in wheat. They are both characterized by the expression of specific isoforms of α-amylase in particular genotypes in the grain prior to harvest. The enhanced expression of α-amylase in both LMA and PHS results in a reduction in Falling Number (FN), a test of gel viscosity, and subsequent downgrading of the grain, a...

We reported previously that intranasal instillation of a synthetic human pulmonary surfactant with a carboxy vinyl polymer as a viscosity improver, named SF-10, shows potent adjuvanticity for humoral immunity in mice and cynomolgus monkeys. SF-10 effectively induces influenza hemagglutinin vaccine (HAv)-specific IgA in nasal and lung washes and IgG in sera with their neutralizing activities. Si...

acrylamide was grafted in low density polyethylene during melt processing in the presence of a free radical initiator using a torque rheometer in a closed system. effects of processing time, acrylamide and benzoyl peroxide concentrations were studied. ftir studies revealed that the degree of grafting increased by an increase in acrylamide concentration. maximum grafting was obtained at 7 minute...

Wheat flours mixed with four types of sweeteners; sugarcane, palm sugar, coconut sugar and sorbitol were evaluated for their in vitro starch digestibility, estimated glycemic index (GI) and physicochemical properties. It was found that sorbitol which is a sugar alcohol gave the best starch digestibility results providing the lowest estimated GI values. Palm and coconut sugars provided better st...

This study aimed to determine the physicochemical, hydration, and rheological characteristics of flours derived from different crop residues (taro, cassava, maize, banana) affected by climate change in Honduras investigate their potential application food processes. The physicochemical (moisture content, ash, protein, crude fat, starch, amylose color), hydration (water absorption capacity (WAC)...

This study treats one important aspect of starch-filled rubber compounds which is their rheological behavior. Starch-based SBR1712 masterbatches resulting from various formulations were prepared using a mini two roll mill and an internal mixer (Plastograph Brabender).The content in starch was varied from 0 to 50 phr. The effect of starch content on the rheological behavior was ev...
