Herein, a new <em>V</em>-type starch-cyclodextrin composite carrier was constructed to efficiently encapsulate p-anisaldehyde in addressing the inherent disadvantages. The introduction of β-cyclodextrin (β-CD) enhanced the short- and long-range ordered structures of the composite carrier. The <em>V</em>-type starch-cyclodextrin composite (<em>V</em>C30) exhibited the highest loading capacity of 142.01 mg/g for p-anisaldehyde, which was significantly higher than that of <em>V</em>-type starch (VS, 97.83 mg/g) and commercial β-CD (128.48 mg/g). The loading capacity of the V-type starch-cyclodextrin composite was positively correlated with its crystallinity and short-range order. The release rate of p-anisaldehyde was in the order of VC30 < β-CD < VS. Under non-cold chain daily storage (25 °C and 57 % relative humidity) for 2 weeks, the p-anisaldehyde of thymol released from complexes was 36 % (VC30), 49 % (β-CD), and 65 % (VS), respectively. Due to the high loading capacity and good sustained release properties, the noncontact preservation of high-value fruit by <em>V</em>C30 controlling p-anisaldehyde release successfully extended the shelf life of cherries from six to twelve days.</div></div>","PeriodicalId":261,"journal":{"name":"Carbohydrate Polymers","volume":"358 ","pages":"Article 123513"},"PeriodicalIF":10.7,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143687724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By adsorbing onto specific crystal surfaces, HPMC was able to modulate the crystal growth orientation, reduce the contact angle, and improve the wettability of drug crystals.

The effects of CNF dosage, aspect ratio, and surface carboxyl content on the filler flocculation process were systematically investigated, with additional enhancement achieved through cationic ion crosslinking to improve filler bridging.

Detailed analyses of filler morphology and distribution elucidated the structure-property relationships underlying this performance. Furthermore, the versatility of the approach was demonstrated with other functional fillers, imparting properties such as flame retardancy, oil/water separation, high brightness, and soluble organic pollutant absorption.

We explored the impacts of these structures on biological activities, specifically the regulation of anti-inflammatory, antioxidant, and immunomodulating effects of polysaccharides. The chemical mechanism of polysaccharides changes during CMMP is also discussed. Different processing methods result in distinct structural variations of polysaccharides, which in turn significantly affect their physicochemical properties and health functions. Therefore, a comprehensive understanding of the processing-structure-activity relationships of polysaccharides is crucial to realizing polysaccharide preparations with targeted functional effects.
