Special Issue Information

Dear Colleagues,

Starch is the second-most abundant biomass material used by plants and algae as an energy reserve. It is also an important source of dietary carbohydrates, accounting for more than half of the calories in the human diet. In the food industry, starches serve as the main constituent of staple food such as pastries, crackers, noodles, bread, and pasta. Additionally, native and modified starches are widely used as bulking agents, gelling agents, thickeners, water retention agents, colloidal stabilizers, bioactive carriers, etc. Starches from different botanical sources may be applicable for different uses. Conventional starch sources are corn, potato, wheat, rice, and cassava. Recently, unique properties of starches from some nonconventional sources, including mung bean, lotus, acorn, quinoa, and amaranth, have been identified, with promising potential in the food industry.

In this context, we invite authors to contribute to this Special Issue with articles related to the structure, properties, and modifications of starches and their applications in the food industry.

Original papers and reviews that focus on, but are not limited to, the following topics are welcome: 1) structures and properties of starches from nonconventional sources; 2) novel techniques for the modification of conventional starches with tailored functionalities; 3) emerging technologies for the production and quality improvement of starchy foods; 4) steering the nutritional properties of starchy foods or designing low-GI starchy foods.

Addressing the challenge of blood glucose fluctuations triggered by the ingestion of pea starch, we have adopted an eco-friendly strategy utilizing microwave irradiation to synthesize the novel pea starch–tea polyphenol complexes. These complexes exhibit high swelling capacity and low solubility, and their thermal profile with low gelatinization temperature and enthalpy indicates adaptability to various processing conditions. In vitro digestion studies showed that these complexes have a small amount of rapidly digestible starch and a large amount of resistant starch, leading to a slower digestion rate. These features are particularly advantageous for diabetics, mitigating glycemic excursions. Structurally, the pea starch–tea polyphenol complexes exhibited a B + V-shaped dense network with low crystallinity, high orderliness, and a prominent double helix content, enhancing its stability and functionality in food applications. In summary, these innovative complexes served as a robust platform for developing low glycemic index foods, catering to the nutritional needs of diabetics. It offers an environmentally sustainable approach to food processing, fostering human well-being and propelling innovation in the food industry. Full article

Empirical evidence indicates that NaCl can improve the quality of mung bean starch sheet jelly (MBSS) when properly incorporated. In this study, by comparison with a sample without NaCl, the influences of NaCl (1.5–8%, w/w) on the physicochemical and structural properties of mung bean starch (MBS) and the quality of MBSS were investigated. MBS with added NaCl had greater gelatinization temperature and pasting parameters but lower gelatinization enthalpy than native MBS. With the addition of NaCl, the drying rate of MBSS first accelerated and then declined in the oven-drying process. The addition of NaCl improved the cooking properties of MBSS but decreased the hardness of cooked MBSS. Rheological results implied that the linear viscoelastic region of cooked MBSS decreased with the NaCl addition, and the storage modulus and tan δ were more frequency-dependent than the loss modulus of cooked MBSS. The addition of NaCl gradually increased the toughness of dried MBSS and the overall acceptability of cooked MBSS. Furthermore, NaCl decreased the structure order degree of starch in MBSS. Correlation analysis demonstrated that the quality of MBSS had a significant correlation with the molecular and lamellar order of starch. Overall, NaCl could improve the quality of MBSS by regulating the thermal, gelatinizing, and structural properties of MBS. Full article
