Rheological and gel properties of hydroxypropyl methylcellulose/hydroxypropyl starch blends

Effect of polysaccharides with different ionic charge on the rheological, microstructural and textural properties of acid milk gels

“…A study on pure cross-linked tapioca starch showed that this starch had gelling property and 1% concentration was high enough to produce an elastic network-like structure (Wongsagonsup et al, 2014). Gelation occurs during cooling through cross-linking of the chains of amylose by hydrogen bonds (BeMiller & Whistler, 2009;Zhang et al, 2015). As starch existed in a mixed system with milk protein gel in our study, a higher gelling concentration than in a pure starch system could be expected.…”

On the investigation of thermal/cooling-gel biphasic systems based on hydroxypropyl methylcellulose and hydroxypropyl starch

“…Hydroxypropyl methylcellulose (HPMC), a derivative of cellulose, the richest natural polymer on the Earth, has good water solubility and biodegradability, and excellent film-forming, mechanical and barrier properties. Therefore, HPMC has been extensively used in food packaging, medicinal capsules, and other drug delivery systems (Imran et al, 2014;Zhang et al, 2017a;Zhang et al, 2015;Zhang et al, 2017b). However, the high prices of HPMC limit its general applications, even for use in therapeutic delivery systems (Wang et al, 2016a;Wang et al, 2016b;Zhang et al, 2013b;Zhang et al, 2013c).…”

“…Hydroxypropyl starch (HPS) is a typical chemically modified starch and is an inexpensive material being widely used in the food industry (Wang et al, 2016a;Zhang et al, 2015). Therefore, the commercial potential of HPMC/HPS is foreseeable for a broad range of applications such as food packaging, food, and medicines.…”

Morphology and properties of thermal/cooling-gel bi-phasic systems based on hydroxypropyl methylcellulose and hydroxypropyl starch

“…However, HPMC films have insufficient barrier properties [25,[27][28][29][30][31]. Besides, its high prices limit its general applications even for pharmaceutical products as medicinal capsules [32][33][34][35][36]. Therefore, it is imperative to improve the processibility and performance, as well as to decrease the costs, of HPMC.…”

“…Therefore, it is imperative to improve the processibility and performance, as well as to decrease the costs, of HPMC. Hydroxypropyl starch (HPS) is one of the most promising materials to reduce the costs of HPMC films, as it is a popular low-price food ingredient [31,37] and has good film-forming property [38][39][40][41][42][43].…”
