Special Issue Information

Dear Colleagues,

Starch is a vital carbohydrate in food systems, which serves as a key source of energy and as a functional ingredient due to its unique set of physicochemical properties. Composed of amylose and amylopectin, starch exhibits distinct behaviours during processing, such as gelatinization, retrogradation, and pasting, which influence the texture, stability, and sensory attributes of food products. This Special Issue, entitled “Starch: Properties and Functionality in Food Systems”, highlights advancements in starch science and its applications across various stages of the food industry. The ability of starch to form gels, thicken, and stabilize makes it indispensable in applications ranging from baked goods and sauces to dairy and meat products. It also plays a critical role in gluten-free formulations and as a fat replacer in low-calorie foods. Furthermore, modifications, including chemical, physical, or enzymatic treatments, enhance its functionality, enabling tailored solutions for specific food applications. A deep understanding of starch’s structure, properties, and interactions with other food components is essential for optimizing its functionality and addressing evolving consumer demands for quality, nutrition, and sustainability in food systems.

In this Special Issue of Foods, we aim to compile a collection of innovative reviews and research that offers a comprehensive understanding of the structure of native or modified starch, while also exploring its functional properties and applications in food systems.

Underutilized starch sources are gaining increasing recognition. However, the inherent functional deficiencies of native starch have limited its application in food industry. To counteract the deficiencies in its native characteristics, starch can be modified by acetylation. Two waxy starches (proso millet and amaranth) and four non-waxy starches (foxtail millet, quinoa, buckwheat, and oat) were modified by acetic anhydride and vinyl acetate, respectively. Degree of substitution of acetylated starches revealed that granule size did not significantly affect acetylation efficiency in starches from different plant origins. Acetylation increased peak and final viscosity of starches, with vinyl acetate exhibiting a more pronounced effect than acetic anhydride. Acetic anhydride decreased K and increased n values of non-waxy starches, showing reduced thickening ability. In contrast, vinyl acetate modification showed opposite trends, suggesting increased viscosity and pseudoplasticity. For non-waxy starches, G′25°C, G′0.1Hz, G′20Hz and gel hardness decreased after acetylation, indicating that acetylation contributed to a less solid and less elastic gel network. The extent of change in vinyl acetate modification was more pronounced than that of acetic anhydride. For waxy starch, vinyl acetate modification decreased tan δ25°C and increased gel hardness. In summary, acetylation reagent type was the major factor determining the pasting properties of acetylated starch, but the presence or absence of amylose would influence the rheological and gel properties of acetic anhydride and vinyl acetate modified starches. These findings could help unlock the potential applications of acetylated underutilized starches in the food industry. Full article
