Article Synopsis
- - The study explores how different starch molecular structures affect gut bacteria and the production of short-chain fatty acids (SCFAs), proposing that specific sizes and chain lengths of starch favor certain gut bacteria.
- - In vitro fermentation tests revealed that tapioca and waxy maize starches were more effective in producing SCFAs like acetate and propionate than other starches like lentil, wheat, and pea.
- - Findings indicate a positive correlation between the number of amylose chains of a certain length and the abundance of specific gut bacteria that enhance SCFA production, suggesting the potential for starches to be used to improve gut health.
Article Synopsis
- Citric acid-modified starch works as a resistant starch, but its effects on gut bacteria and short-chain fatty acid (SCFA) production need more study.
- Researchers created different versions of this modified starch from rice and looked at how they affected gut microbiota and SCFA levels.
- They found that starch with a higher degree of substitution decreased acetate but increased butyrate production, and specific amylopectin and amylose structures influenced the growth of certain gut bacteria, which could improve health.
Multi-scale structures were investigated to understand starch digestibility of instant rice. A wide range of maximum starch digested ratio, up to about 20%, was observed among instant rice prepared from different rice varieties. Instant rice with a smooth and densely packed cross-section showed slower starch digestibility than those with a porous and loosely packed structure.

In this review, the main factors determining starch digestibility of instant rice were comprehensively evaluated, aiming to help the rice industry develop instant rice with slow starch digestibility. Starch digestibility in instant rice can be reduced by manipulating its intrinsic and extrinsic nutrients.

Recently, an efficient frequency conversion system using a double- four-wave mixing (FWM) process based on electromagnetically induced transparency (EIT) has attracted considerable attention because of its potential to achieve a nearly 100% conversion efficiency (CE). To obtain such a high CE, the spontaneous emission loss in this resonant-type FWM system must be suppressed considerably.

Herein, we demonstrate that spontaneous emission can be considerably suppressed by arranging the applied laser beams in a backward configuration. With the backward double-Λ FWM scheme, we observe a CE of 63% in cold rubidium atoms with an optical depth (OD) of 48.
