Special Issue Information

Dear Colleagues,

Starch, the principal storage polysaccharide of most plant-originated foods, is abundantly present in a discrete and semi-crystalline granular pattern in legumes, potatoes, and cereals. Depending on the processing conditions, starch from different sources with diversified structural characteristics can be formed through rearrangement in the intermolecular structure of starch granules. Unlike the traditional purpose of food processing, which aims to increase the digestibility of food, current food processing has gradually switched to the design of palatable foods with a reduced glycemic index and improved functional properties. The physical modifications to starch during the processing of starch-based materials address several shortcomings of native starch that have limited its industrial application, such as its low heating stability/poor thermal property, low resistance to acid, low shear stress, and high tendency toward syneresis and retrogradation. A deep understanding of the corresponding physicochemical and functional properties, as well as of the effects of isolation and different processing conditions, is of great importance for starch scientific research and also for future studies on the structure–physicochemical/function relationship of starch from different botanical origins. This Special Issue aims to provide an overview of the current and projected outcomes in the physicochemical, structural, and functional properties of starch from legumes, potatoes, and cereals, as well as changes in the above properties during the processing of starch-based materials and their derived food products. Researchers are invited to submit their up-to-date original research articles, review works, and short communications to this Foods Special Issue: “The Processing, Physicochemical, Structural, and Functional Properties of Starch-Based Materials and Their Derived Food Products—Second Edition”.

Dendrobium officinale (DO) is a well-known medicinal and edible plant, yet its impact on the quality of noodles has been infrequently reported. In this study, DO was incorporated into multi-grain flour in varying proportions (0, 2, 4, 6, 8%) to prepare noodles, and their quality was assessed. The percentage increase in DO decreased the cooking loss, whiteness, appearance, and taste of the noodles while simultaneously enhancing their water absorption, adhesiveness, smoothness, and starch digestion resistance. Lower supplemental levels of DO (2–4%) facilitated the water absorption of protein and the formation of a dense and extensive protein network surrounding the partially gelatinized starch, which was characterized by higher relative crystallinity. The highest sensory score (77.4) and greatest content of slowly digestible starch content (38%) were observed in the noodles containing 4% DO. Conversely, higher percentages of DO (6–8%) diluted and compromised the protein network in the cooked noodles, leading to water migration from protein to starch. The excessive polysaccharides from DO tended to complex with fully gelatinized starch, promoting starch aggregation and interactions between starch and non-starch components. This ultimately resulted in the highest adhesiveness and resistant starch content (34%) in the cooked noodles with 8% DO. These findings provide a reference for enhancing noodle quality by regulating the amount of DO added, thereby promoting the application of DO in cereal-based food products. Full article

Starches with different degrees of debranching (DBS30, DBS60, and DBS90) and sodium alginate were used as the wall material for encapsulating particles of Lacticaseibacillus rhamnosus GG (LGG). The structural characteristics of these encapsulated particles were examined, along with the impact of varying levels of debranching on the encapsulation efficiency, the in vitro release of LGG under the simulated gastrointestinal environment, and the storage stability of the encapsulated particles. The results revealed a transformation in the crystalline polymorph from C- to B+V-type following debranching and retrogradation. This process also resulted in a significant decrease in molecular weight and polydispersity index, accompanied by an increase in amylose and resistant starch levels along with the relative crystallinity of the debranched lentil starch. Comparatively, DBS60-LGG and DBS90-LGG exhibited higher encapsulation efficiency and encapsulation yield than UDBS-LGG and DBS30-LGG. Furthermore, these encapsulated particles provided enhanced protection for LGG in both the simulated gastrointestinal environment and the storage process. It can be inferred that a superior encapsulation performance of the debranched lentil starch–sodium alginate-based encapsulated LGG particles was associated with higher debranching levels, a more uniform molecular weight distribution, and a more ordered multi-scale structure of the debranched lentil starch.
