The effects of high-temperature storage at 37 °C on the crystallinity, pasting, rheological, and thermal properties of adlay seed starches from three famous Chinese varieties were studied. The results showed that high-temperature storage altered the natural structure of adlay seed starch, resulting in increased peak viscosity for all starch pastes after one month of storage at 37 °C. Jinsha adlay seed starch (JSC), which had the highest amylose content (11.21 %), showed increased D relative crystallinity and OD values, demonstrating strong regrowth ability and hydrophobicity, with starch gels having greater hardness and gumminess after storage. In contrast, Pucheng adlay seed starch (PSC) and waxy Ninghua adlay seed starch (WSC), with similar amylose proportions, showed distinct starch gel properties. PSC (with an amylose content of 3.35 %) exhibited better starch gel properties, whereas WSC (amylose content of 5.74 %) demonstrated improved gumminess and chewiness after storage and exhibited stronger anti-starch regrowth capabilities. This study provides valuable insights into the selection of future starches based on their specific processing requirements.

Article Synopsis
- Adlay seed bran, often wasted or used as animal feed, is studied for its properties and digestive effects, revealing potential benefits for human health.
- Various extraction methods were tested, with enzyme-assisted solid-state fermentation (SSF) yielding the most effective adlay seed bran polysaccharides (ASBPs), specifically ASBP-CF, which had superior extraction rate and nutritional profile.
- ASBP-CF demonstrated significant prebiotic effects, enhancing beneficial gut bacteria and short-chain fatty acid production, suggesting its role as a valuable dietary supplement for gut health improvement.

Proliferative vitreoretinopathy (PVR) is a vision-threatening condition associated with retinal-detachment (RD), primarily caused by fibrocellular scar membrane formation. This study investigates the therapeutic potential of adlay seed extract fractions in mitigating PVR-associated pathways, focusing on oxidative stress, proliferation, inflammation, and fibrogenesis in retinal pigment epithelial (RPE) cells. Adlay seed extract fractions (methanolic: MeOH and residual: Res) were obtained through solvent extraction and characterized for carbohydrate, protein, flavonoid content, and antioxidant activity.

Adlay millet seeds are well known for excellent health benefits. However, using fungal fermentation to improve their nutritional and functional constituents and the underlying mechanisms has not been thoroughly investigated. Herein, we used Rhizopus oryzae as starter and applied metabolomics combining with quantitative verification to understand the changes of the nutritional and functional profiles of adlay millet seeds.
