An Attempt of Using β-Sitosterol-Corn Oil Oleogels to Improve Water Barrier Properties of Gelatin Film.

Oleogel with tailored viscoelasticity is a great interest for food structuring, while its potential benefits for edible film performance are not clear. In this study, β-sitosterol (0, 5, 10, 15, and 20 wt%)-corn oil oleogel was developed and used in the formation of gelatin-based films. Importantly, adding oleogel significantly decreased water vapor permeability of the gelatin films, however, it had little negative influence on film strength.

Mechanical and barrier properties of maize starch-gelatin composite films: effects of amylose content.

Background: In order to obtain new reinforcing bio-fillers to improve the physicochemical properties of gelatin-based films, three types of maize starch, waxy maize starch (Ap), normal starch (Ns) and high-amylose starch (Al), were incorporated into gelatin film and the resulting film properties were investigated, focusing on the impact of amylose content.

Results: The thickness, opacity and roughness of gelatin film increased depending on the amylose content along with the starch concentration. The effects of the three starches on the mechanical properties of gelatin film were governed by amylose content, starch concentration as well as environmental relative humidity (RH).

Performance of high amylose starch-composited gelatin films influenced by gelatinization and concentration.

In order to study the impact of starch in film performance, high amylose corn starch was composited in gelatin films under different gelatinization conditions and, in high and low concentrations (10 and 50wt.%). It was found that hot water gelatinized starch (Gel-Shw) increased film mechanical strength and was dependent upon the starch concentration.

Mechanical properties and solubility in water of corn starch-collagen composite films: Effect of starch type and concentrations.

This study investigated the possibility of enhancing the properties of collagen with three different maize starches: waxy maize starch, normal starch, and high amylose starch. Scanning electron microscopy images revealed that starch-collagen films had a rougher surface compared to pure collagen films which became smoother upon heating. Amylose starch and normal starch increased the tensile strength of unheated collagen films in both dry and wet states, while all starches increased tensile strength of collagen film by heating.

Up-regulated biglycan expression correlates with the malignancy in human colorectal cancers.

Biglycan, an extracellular matrix protein, has been implicated in the oncogenesis and cancer development in various types of human cancer. The clinical significance of biglycan in colorectal cancer, however, remains unclear. In the present study, biglycan mRNA expression was analyzed in 110 samples (primary colorectal tumor and matched adjacent normal tissue) derived from 55 patients with colorectal cancer using quantitative real-time RT-PCR.
