Topical Collection Information
Dear Colleagues,
Amongst the biopolymers in nature, starch has received the most attention with respect to its nutritive value and structure–function relations in food and non-food industrial products and applications. Starch and products derived from starch are the major components in food products and can be used to affect the physical properties of many foods. Starches from different sources and genotypes within such sources show substantial diversity in terms of their composition, amylose and amylopectin structure, and structural arrangement of the starch granules, which contribute to different physicochemical properties and thus different functionalities. The desire to deepen our understanding of the relationship between starch structure and functionalities in food systems leads to a highly interesting scientific field. Research on the effects of chemical, enzymatic, and physical modifications of native starches has further improved their properties and expanded the spectrum of starch applications in food systems. In addition, various physical processing techniques such as heat, shear, and moisture regulation highly influence the structure of starch molecules and interactions with other biomolecules and food additives, as well as the sensory and nutritional qualities of final food products. The impact of these interactions on the sensory and nutritional qualities of foods and their safety have been the focus of a number of recent research studies. The current research is also geared towards the importance of starch in human nutrition and health. A new challenge for the food industry is to supply consumers with starch-containing foods with improved nutritional quality. The different forms of starch in foods and novel food processing techniques and their influence on starch digestibility have received tremendous research focus. This topical collection of Molecules aims to acquire in-depth knowledge about some of the aforementioned research concepts in starches and their application in food products.

Neohesperidin (NH), a natural flavonoid, exerts multiple actions, such as antioxidant, antiviral, antiallergic, vasoprotective, anticarcinogenic and anti-inflammatory effects, as well as inhibition of tumor progression. In this study, the NH–taro starch complex is prepared, and the effects of NH complexation on the physicochemical properties, structure and in vitro digestibility of taro starch (TS) are investigated. Results showed that NH complexation significantly affected starch gelatinization temperatures and reduced its enthalpy value (ΔH). The addition of NH increased the viscosity and thickening of taro starch, facilitating shearing and thinning. NH binds to TS via hydrogen bonds and promotes the formation of certain crystalline regions in taro starch. SEM images revealed that the surface of NH–TS complexes became looser with the increasing addition of NH. The digestibility results demonstrated that the increase in NH (from 0.1% to 1.1%, weight based on starch) could raise RS (resistant starch) from 21.66% to 27.75% and reduce RDS (rapidly digestible starch) from 33.51% to 26.76% in taro starch. Our work provided a theoretical reference for the NH–taro starch complex’s modification of physicochemical properties and in vitro digestibility with potential in food and non-food applications.

The objectives of this study were to produce sodium alginate (SA)-based cryogel beads filled with different concentrations (0, 0.4, 1.0, and 2.5%,
w/
w) of hydroxypropyl distarch phosphate (HDP) as a curcumin delivery system and to investigate the physicochemical, structural, and in vitro gastrointestinal tract release properties of the cryogel beads. According to FT-IR analysis, the formation of ionic crosslinking between SA and Ca
2+ and the presence of HDP were found. XRD analysis demonstrated the successful encapsulation of curcumin in the beads by observing the disappearance of the characteristic peaks of curcumin. SEM analysis results revelated that SA-based cryogel beads exhibited a denser internal structure as the HDP concentration was increased. The encapsulation efficiency of curcumin in SA cryogel beads filled with HDP concentration from 0% to 2.5% was increased from 31.95% to 76.66%, respectively, indicating that HDP can be a suitable filler for the encapsulation of curcumin in the production of SA-based cryogel beads. After exposure to simulated gastric fluid (SGF) and simulated intestinal fluid (SIF), the release rate of curcumin was decreased as HDP concentration was increased. Accordingly, SA-based cryogel beads filled with HDP can be utilized for the delivery system of curcumin in the food industry.

The objective of the present study is to enhance the resistant starch (RS) content of high amylose rice starch with heat–moisture treatment (HMT) for industrial application. The optimized HMT condition for achieving the highest RS content established using response surface methodology (RSM) was a temperature of 100 °C, moisture content of 24.2%, and a time of 11.5 h. Upon HMT, the RS content increased from 32.1% for native starch to 46.4% in HMT starch with optimized condition. HMT of the starches reduced the solubility and swelling power. The surface of HMT starch granules was more irregular than native starch. The X-ray diffraction (XRD) peak intensity at 2θ = 5° was greatly reduced by HMT, and the peaks at 22.7° and 24.2° were merged. HMT increased the gelatinization temperature and reduced the gelatinization enthalpy. HMT provides a method for the production of high-yield RS2 with high amylose rice starch in industrial application.
