“…Cellulose derivatives such as hydroxypropyl methylcellulose (HPMC) are promising materials for edible coatings or films for packaging. HPMC is a water‐soluble polymer used in the food industry as a gelling and stabilizing agent (Burdock 2007; Turowski and others 2007). However, cellulose films are poor water vapor barriers because of the inherent hydrophilic nature of polysaccharides.…”

In this study, chitosan nanoparticles were prepared and incorporated in hydroxypropyl methylcellulose (HPMC) films under different conditions. Mechanical properties, water vapor and oxygen permeability, water solubility, and scanning and transmission electron microscopy (SEM and TEM) results were analyzed. Incorporation of chitosan nanoparticles in the films improved their mechanical properties significantly, while also improving film barrier properties significantly. The chitosan poly(methacrylic acid) (CS-PMAA) nanoparticles tend to occupy the empty spaces in the pores of the HPMC matrix, inducing the collapse of the pores and thereby improving film tensile and barrier properties. This study is the first to investigate the use of nanoparticles for the purpose of strengthening HPMC films.

“…These food gums are a good source of soluble fiber and are approved for food use in the USA; an AOAC 2006.08 analytical method has been developed and validated for their analysis Harfmann et al, 2007;Turowski et al, 2007). They are safe food additives without appreciable adverse effects (McCollister et al, 1973;Nitschke and Fiero, 1977;Santos, 1986), undergoing no significant digestion or fermentation in the gut of animals (Braun et al, 1974;Yokoyama et al, 2002) or humans (Machle et al, 1944).…”

Hydroxypropylmethylcellulose significantly lowers blood cholesterol in mildly hypercholesterolemic human subjects

Objective: To determine the cholesterol-lowering efficacy of hydroxypropylmethylcellulose (HPMC) , and 12 and 15% at 15 g day À1 , respectively, over placebo. Adverse effects were minimal. Trial one: medium, high and ultra-high viscosity HPMC at 15 g day À1 for 1 week each; 1-week wash-out between treatments. Trial two: ultra-high viscosity HPMC at 5 or 15 g day À1 for 8 weeks. Conclusions: HPMC soluble fiber, especially high-viscosity grades, significantly lowers cholesterol at well-tolerated doses, showing promise as a treatment of hypercholesterolemia.

“…Of the colorimetric methods available for quantification of CMC, the 2,7‐naphthalenediol method (NDM) is the most specific one (Zorba and Ova 1999). An advanced and sophisticated method of estimation of methyl and HPMC has been recommended by Harfmann and others (2007) whereas a modification to the AOAC procedure with size‐exclusion chromatography for their determination was published by Turowski and others (2007).…”

“…The most recent method of DF determination includes liquid chromatography (Ohkuma and others 2000). Kitada and others (1997) determined SDF using electrophoresis, high‐performance liquid chromatography (HPLC), and size exclusion chromatography (Turowski and others 2007) with refractive index detector (Harfmann and others 2007). Haines and Patel (2003) employed ELISA for the determination of soluble fiber.…”
