Along with other frequently used spices, Chinese chives were put in varying amounts to the prepared dishes—dhal fry, vegetable soup, and sprouting bean salad—in order to assess their organoleptic qualities.Nutritional analysis shows a significant presence of dietary fiber (16.11 g/100 g), total phenol (988.76 GAE/100 g), total flavonoid (821.28 mg CE/100 g), and chlorophyll content (27.59–32.99 µ/g). In addition, it possess high antioxidant properties such as DPPH inhibition (47.07), ABTS inhibition (37.29), FRAP (2.57 µmolFe(II)/g), ORAC (4.17 µmol TE/g). Furthermore, an abundance of linoleic, α-linolenic and oleic acids was displayed. Chinese chive instant spice mix that displayed the highest level of acceptability was selected for storage studies for 90 days by determining moisture, free fatty acid, and peroxide values by withdrawing periodically every month. The spice mix's quality parameters did not significantly change; however, there was a minor increase in moisture content—from 7.54 to 7.74%. Nevertheless, no notable variations were discovered, indicating that the created spice blends may be kept for three months with little alterations. Because of its high nutritional and antioxidant potential, this study suggests that Chinese chives can be utilized to make a nutritious spice mix that delivers health-beneficial chemicals.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"79 8","pages":"5087 - 5100"},"PeriodicalIF":2.5,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the accumulation of the unused drugs in semi-metabolized state in the natural water systems through manufacturing plants, hospitals or consumers at large, have led to a serious trouble. This review article aims to present a short summary of the various methods proposed for the removal of antibiotics and non-steroidal Anti-Inflammatory Drugs (NSAIDs) from aquatic systems through adsorbents synthesized using chitosan and its different structurally modified versions. Chitosan, being abundantly available in nature, has become the most preferable material as adsorbent for a variety of contaminants including dyes, heavy metals, fluoride, drugs, fertilizers, etc. Thus, we present three important structural modifications of chitosan namely crosslinked/grafted chitosan, chitosan hydrogels/microspheres and chitosan composites as potential adsorbents for commonly used antibiotics and drugs. The study also includes the optimized pH conditions for adsorption, isotherm, kinetics and mechanism of adsorption as well as maximum adsorption capacity obtained for the drug.</p><h3>Graphic abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"79 7","pages":"4087 - 4107"},"PeriodicalIF":2.5,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145145527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
