Summary: Microencapsulation of beta-carotene (8-C) in amaranth carboxymethyl starch (CMS) and lactoferrin (LF) complex coacervates was achieved for application in gummy candies. The microcapsules showed spherical morphology and good photolytic and thermal stabilities. Release of 8-C was highest in the intestines and soybean oil, but low in ethanol. Addition of 8-C microcapsules reduced the hardness of gummy candies and allowed 22% bioaccessibility.

Summary: The aim of this research is to investigate the effects of amaranth flour on the composition, rheology, technology, and sensory characteristics of bread. The study found that the microstructure and molecular characteristics of amaranth flour depend on its particle size and replacement level. The replacement of wheat flour with amaranth flour fractions had a significant impact on the protein, lipids, ash, moisture, and carbohydrate content of the composite flour. It also affected the rheological behavior, bread volume, firmness, porosity, and color of the bread.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
