Currently, rice ( L.) production and consumption is increasing worldwide, and many efforts to decrease the substantial impact of its byproducts are needed. In recent years, the interest in utilizing rice kernels, husk, bran, and germ for the recovery of different molecules, from catalysts (to produce biodiesel) to bioactive compounds, has grown.

- - Pectin is a natural biopolymer primarily extracted from citrus peels and apple pomace, but there is growing interest in using alternative food waste sources due to increasing market demand, projected to reach 2.12 billion by 2030.
- - This review discusses the chemical properties of pectin that impact its various applications, like esterification degree and molecular weight, and provides insights into its recent uses in nutraceutical and food sectors.
- - There is a recognized need for more research on the complexity of pectin structures derived from new food waste sources to better understand their potential for commercial applications.
Article Synopsis
- - Rice husk is identified as a promising source of polyphenols, but it's currently underutilized in food systems; this study aims to explore its potential in preventing protein glycation through in vitro assays.
- - A microwave-assisted extraction method was optimized to efficiently recover polyphenols from rice husk, achieving the best results with specific conditions of temperature, time, and solvent concentration.
- - The study found that the rice husk extract effectively inhibits early and middle stages of glycation, showing a dose-dependent effect, strong antioxidant activity, and contains key polyphenols recognized for their anti-glycative properties.
Chlorogenic acids are hydroxycinnamic derivatives widespread in food or food by-products, known for their antioxidant effects and ability to interfere with the formation of advanced glycation end products (AGEs). AGEs are potential glycotoxins involved in age-related disorders, such as diabetes, cardiovascular diseases, and neurological disorders. The ability of chlorogenic acids to inhibit AGE formation under physiological conditions needs further investigation other than the assays.

- The use of bioactive compounds in food supplements has gained interest, but their low solubility, stability, and bioaccessibility make them less effective.
- To improve their effectiveness, various carriers, including lipid, protein, and polysaccharide-based systems, have been explored for encapsulating these compounds, each with unique interaction patterns.
- The review highlights the development of innovative plant-based carriers that prioritize natural ingredients, discussing design considerations and the potential of mixed systems to enhance encapsulation efficiency.
Article Synopsis
- There is a growing demand for affordable and effective early treatments for diabetes, leading to a renewed interest in natural remedies, particularly plant-based options.
- The study focuses on the Italian mulberry plant, examining twelve different cultivars to understand their chemical composition and bioactivity, which has previously only been explored in Asian varieties.
- Findings suggest that certain compounds in mulberry leaves, like 1-deoxynojirimycin and kaempferol, work together to inhibit digestive enzymes and may help prevent complications associated with diabetes.
Article Synopsis
- The agri-food sector generates significant waste, impacting environmental, economic, social, and health aspects, highlighting the need for effective reuse and recycling methods.
- Innovative green extraction techniques, like microwave, ultrasound-assisted, supercritical fluid, and pressurized-liquid extraction, are prioritized over traditional methods for recovering valuable compounds such as chlorogenic acids from agri-food wastes.
- Although these new extraction methodologies show great potential, further research and optimization are necessary before they can be implemented in industrial processes.
In vitro digestion models are essential to predictively evaluate the bioaccessibility and bioactivity of food molecules or natural products. Dynamic models better simulate the gastrointestinal conditions as they reproduce similar physiological environments. Despite this, static methods, also known as biochemical methods, represent a simple and useful approach for the study of different types of molecules, with a broad applicability in the nutritional, pharmaceutical, and toxicological fields.
