Wheat starch was treated by different gamma-radiation doses (3, 5, 10, 20, 35 and 50 kGy). The effects of gamma-radiation on on structural, thermal, physicochemical, morphological and rheological properties of wheat starch were studied. The presence of free radicals after gamma-radiation treatment, which number decreased with time was confirmed. Structural analysis revealed decreases in the intensities of the O-H and C-H stretches and glycosidic linkages indicating the depolymerization of amylose and probably amylopectin into shorter chain molecules, but showed that gamma-radiation treatment did not affect the crystalline structure. Differential scanning calorimetric (DSC) thermograms showed the absence of significant differences in the gelatinization temperatures, as well as the corresponding transition enthalpies since the DSC parameters are related to the crystalline ordering within the granules. Apparent amylose content decreased linearly with increasing irradiation dose leading to an increase in water solubility index. An increase in the swelling power was observed after irradiation treatment until 20 kGy, followed by a rapid decrease at higher doses. Microscopic observations showed that the effect of gamma-radiation was more visible on starch pastes than on starch granules. Rheological properties of the starch pastes decreased with increasing irradiation dose as a result of glycosidic bond cleavage. (C) 2015 Elsevier B.V. All rights reserved.

Physicochemical Properties of Palm Oil-Based Puff Pastry Model Margarines Related to Their Baking Performance in Long-Term Storage

Roxane Detry, Vera Van Hoed, Jerome Sterckx, Catherine Deledicque, Kiyotaka Sato, Christophe Blecker, Sabine Danthine

Summary: The research found that the triacylglycerol (TAG) composition of palm oil-based puff pastry margarines significantly influences post crystallization processes and physical properties of the fat crystal network. High levels of 1,3-di-palmitoyl-2-oleoylglycerol (POP) may have negative impacts. Proper balance of POP, 1,2-di-palmitoyl-3-oleoylglycerol (PPO), and tripalmitoylglycerol (PPP) proportions is crucial in preventing detrimental effects on the fat's characteristics and baking performance.

Effect of high-intensity ultrasound on the oleogelation and physical properties of high melting point monoglycerides and triglycerides oleogels

Thais Lomonaco Teodoro da Silva, Sabine Danthine

Summary: The synergy of binary oleogels structured by monoglycerides and high melting point triacylglycerols was evaluated, with the best physical properties found in the MG6:HF0 oleogel. High-intensity ultrasound improved the properties of blends of monoglycerides and high melting point triacylglycerols, but had a negative effect on the MG6:HF0 oleogel. Sonocrystallization induced secondary nucleation and changes in the crystalline material only in blends containing high melting point triacylglycerols, indicating a better effect of sonocrystallization on oleogels with high melting points.

Effects of aging and diabetes on the deformation mechanisms and molecular structural characteristics of collagen fibrils under daily activity

Wei-Han Hui, Yen-Lin Chen, Shu-Wei Chang

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.
