“…Using physical, chemical, or enzymatic methods such as molecular cutting, rearrangement, oxidation, or introduction of substituents into starch molecules can produce modified starches with altered, enhanced, or new physicochemical properties. Modified starch overcomes the shortcomings of natural starch, such as poor freeze-thaw stability, low solubility, easy retrogradation, and low transparency, further expanding its range of applications in related industries ( Masina et al., 2017 ; Wang et al., 2020c ). In food processing, modified starch is widely added to food as a partial fat substitute to provide the shape, taste, thickening, gelling, adhesiveness, and stability required by the food system while avoiding the perception that high-fat meat products will cause cancer ( Heinen et al., 2009 ; Kapelko-Żeberska et al., 2015 ; Kaur et al., 2018 ) ( Figure 1 B).…”

Starch is a vital energy source for living organisms and is a key raw material and additive in the food and non-food industries. Starch has received continuous attention in multiple research fields. The endosperm of cereals (e.g., rice, corn, wheat, and barley) is the most important site for the synthesis of storage starch. Around 2010, several excellent reviews summarized key progress in various fields of starch research, serving as important references for subsequent research. In the past 10 years, many achievements have been made in the study of starch synthesis and regulation in cereals. The present review provides an update on research progress in starch synthesis of cereal endosperms over the past decade, focusing on new enzymes and non-enzymatic proteins involved in starch synthesis, regulatory networks of starch synthesis, and the use of elite alleles of starch synthesis-related genes in cereal breeding programs. We also provide perspectives on future research directions that will further our understanding of cereal starch biosynthesis and regulation to support the rational design of ideal quality grain.

“…These Figures present the starch granules deposited in the rubberwood ray parenchyma cells. Starch molecules are polymers of anhydrous glucose units formed and accumulated through the long-term energy storage of different plants in the form of unique and isolated granules [18,19]. According to Simatupang et al [19], fresh rubberwood contains 1.05% to 2.29% free sugars and 7.53% to 10.17% starch.…”

Effect of Glue Spreads on the Structural Properties of Laminated Veneer Lumber from Spindleless Rotary Veneers Recovered from Short Rotation Hevea Plantation Logs

et al. 2021

Unproductive young rubber trees (15 years old) with smaller diameters (15 to 18 cm) compared to conventional rubber logs, harvested at the age of 25 years old, were selected for the production of laminated panels. Spindleless rotary veneer peeling was applied to logs from short-rotation rubber forest plantations to produce veneers for structural purposes. This raises questions about the utilization of these small-diameter logs with respect to its effect on the quality of veneer and laminated panels produced. This study examines the effect of the glue spread rates on the physical and mechanical properties of rubberwood laminated veneer lumber (LVL). Analysis of variance shows that the application of a 280 g/m2 glue spread rate significantly improved the density, water absorption and dimensional stability of rubberwood LVL. The mechanical properties of rubberwood LVL produced with a 200 g/m2 glue spread rate met the minimum requirement for the 2.1E-3100F stress class; 91.05 MPa for the modulus of rupture in the flatwise direction and 50.23 MPa for compressive strength parallel to the longitudinal axis. The modulus of elasticity in the flatwise direction of 11,189.55 MPa reached the minimum requirement for the 1.5E-2250F stress class.

“…Blending starch with more hydrophobic polymers has been shown to be an interesting combination to produce films for packaging with improved properties 30 . However, because of the intrinsic hydrophilicity of native starch, the poor compatibility between starch and hydrophobic polymers can become a problem to the production of the films 31 . From this perspective, microfluidization, a highpressure homogenization technique, would constitute and alternative route to obtain films from polymers of different hydrophilicities, improving miscibility and film properties, including appearance and mechanical properties 32,33 .…”

Effect of Starch Laurate Addition on the Properties of Mango Kernel Starch Films

et al. 2021

In this work, starch obtained from mango kernel seeds was applied in the preparation of films in combination with its hydrophobic derivatives. Chemical modification of starch was carried out at two different concentrations of vinyl laurate, in dimethyl sulfoxide, under basic catalysis. The degrees of substitution of the starch laurates were 2.4 and 0.3, respectively. None of the products formed films when dispersed in water. However, blends of starch/starch laurate (degree of substitution = 0.3) formed films after microfluidization of their aqueous suspensions. The blends with up to 15% wt of starch laurate (degree of substitution = 0.3) resulted in films of higher elongation at break, higher opacity and lower tensile strength and elastic modulus. The microfluidization of biopolymer suspensions was crucial to obtain films with lower water vapor permeability. X-ray diffraction results corroborated to the mechanical properties of the films, showing that the incorporation of starch laurate reduced the starch films crystallinity.
