Abstract
This research verified the in vitro digestive properties of potato starch modified with citric acid (CA), malic acid (MA), and tartaric acid (TA), and evaluated its prebiotic potential. The resistant starch (RS) content in CA- or MA-modified starch was greater than that in native starch. Furthermore, after cooking, all modified starches exhibited an increase in RS content by 2.3 to 3.3 times compared to native starch, which has a 29.81% RS content, demonstrating high thermal stability. Probiotic bacteria demonstrated increased viability, raiging form 6.38–6.85 log CFU/mL, when cultured with modified starch, in contrast to 4.48 log CFU/mL with glucose. During animal testing, modified starches consistently improved gastrointestinal transit, fecal moisture, and lipid levels. Notably, CA-, MA- or TA-modified starches promoted beneficial bacteria growth by providing short-chain fatty acids, with CA-modified starch proving to be the most potent.
期刊介绍：
The FSB journal covers food chemistry and analysis for compositional and physiological activity changes, food hygiene and toxicology, food microbiology and biotechnology, and food engineering involved in during and after food processing through physical, chemical, and biological ways. Consumer perception and sensory evaluation on processed foods are accepted only when they are relevant to the laboratory research work. As a general rule, manuscripts dealing with analysis and efficacy of extracts from natural resources prior to the processing or without any related food processing may not be considered within the scope of the journal. The FSB journal does not deal with only local interest and a lack of significant scientific merit. The main scope of our journal is seeking for human health and wellness through constructive works and new findings in food science and biotechnology field.
