Advancements in research sector have led to the development of biodegradable materials, namely starch‐based biodegradable films, which have the potential to reduce this environmental impact. Starch is a unique biopolymer with distinctive chemical, physical, mechanical, thermal, and optical properties that make it an attractive alternative to nonbiodegradable and harmful materials. This review paper comprehensively discusses the properties of starch and the techniques involved in transforming native starch into starch‐based films. Further a broad overview of recent research on combining starch with several composites to enhance the physicochemical properties has been discussed herein. In addition, this paper also discusses recent insights into the development of starch‐based composite films and their potential applications in food packaging systems. Future studies must focus on the development of starch composites that strike a balance between different versatile properties of the biopolymer. Additionally, a critical examination of the interactions at the molecular level will help to expand our understanding of this sustainable biopolymer. Ultimately, the findings of this review paper will provide valuable insights for researchers and industry professionals interested in the development and utilization of starch‐based biodegradable films.","PeriodicalId":501569,"journal":{"name":"Starch","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140883461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, starch‐co‐poly(methyl methacrylate) (St‐co‐PMMA) copolymeric matrix is sandwiched within Mg‐Al layered double hydroxides (Mg‐Al LDH) along with silver nanoparticles (AgNPs) via surfactant free in situ polymerization of MMA. The imprintment of LDH and AgNPs within the copolymeric matrix of starch and their interactions are analyzed by the Fourier transform infrared (FTIR) spectroscopy and X‐ray diffraction (XRD) study. The morphological analysis is carried out by field emission scanning electron microscopy (FESEM), which indicates the reduction of voids by the partial intercalation and exfoliation of LDH layers. This dispersive effect offered by the combination of LDH and AgNPs not only results in an eight‐fold increase in oxygen barrier properties, but also enhances the chemical resistance attributes of the St‐co‐PMMA@Ag/(Mg‐Al)LDH nanocomposite films (NFs) with increase in LDH loading. Antibacterial activity is rendered by the presence of AgNPs and is further accentuated by increasing the concentration of LDH in the nanocomposite films. This significant elevation in thermal stability, chemical resistance, barrier properties, and bactericidal nature makes the material potential for packaging applications.","PeriodicalId":501569,"journal":{"name":"Starch","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140808938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three types of tablets are prepared: sago starch binder tablets, xanthan gum binder tablets, and dry press tablets (used as a control). The tablets are investigated for their physicochemical structure, mechanical properties, in‐vivo bioactivity, and antibacterial efficiency using various characterization techniques such as Fourier transform infrared (FTIR), field emission scanning electron microscope (FESEM), XRD, ICP, etc. The results indicate the formation of a hydroxyapatite (HA) layer on the surface of the tablets after immersion in simulated body fluid (SBF) for 28 days, demonstrating their bioactivity. FESEM analysis reveals the formation of HA crystals with different morphologies, including oval‐shaped crystals in sago tablets and needle‐like crystals in xanthan tablets. The binder tablets exhibit higher Ca/P ratios compared to the press‐dried tablets. Among the binder tablets, sago starch tablets show superior mechanical properties. Additionally, the binder tablets display efficient antibacterial activity against Staphylococcus aureus and Escherichia coli bacteria. These findings highlight their potential as promising candidates for bone tissue engineering applications.","PeriodicalId":501569,"journal":{"name":"Starch","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140809300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

IR‐heating at 200 °C allows one to reduce the processing time to 15 min and does not lead to irreversible amorphization of starch structure. Upon IR‐DHT, an increase in density of starch granules from 1.4888 ± 0.0005 to 1.5038 ± 0.0005 g cm−3 is observed. The crystallinity degree of the starch exposed in water at 20 °C after IR‐DHT does not change compared to the crystallinity of native starch hydrated at the same temperature. However, the exposure in excess of water of native potato starch at 45 °C induces an increase of crystallinity up to 81% (along with a significant increase in the intensity of the d100 reflection), while heat‐treated starch exposed in water at the same temperature has reduced crystallinity (RC = 39%). In addition, the concentration of soluble carbohydrates released during the exposure process (45 °C, excess of water) increases by an order of magnitude for heat‐treated starch compared to the native sample. Hence, IR‐DHT may become a promising way to influence the processes of acid and enzymatic hydrolysis and control starch properties, such as pasting, solubility, and digestibility.","PeriodicalId":501569,"journal":{"name":"Starch","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140810338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
