In order to improve the water-resistance and ultraviolet (UV) barrier properties of pullulan (PL) film, edible composite films were prepared by solution casting based on PL and shellac (SH). The physical properties, thermal stability, mechanical properties, water vapor permeability and UV barrier of the composite films were characterized. The analysis of the functional properties revealed that the composite films had good compatibility, water-resistance (33.50˚–60.15˚), and strong UV-blocking properties (84.60%–0.00%). The addition of SH improved the water-resistance and mechanical properties of the films, but the thermal stability was slightly reduced. These films can be used as an edible coating on Chinese cherries. According to the characteristics of weight loss, decay incidence and other indicators of cherries, the PL-SH composite films can keep Chinese cherries fresh at room temperature at least for 7 days. Therefore, PL-SH composite films may be an environmentally friendly packaging material with application prospects in the fruit preservation industry.

To effectively control mold and spoilage of bread and extend its shelf life, this study developed an active packaging material that possesses both antifungal activity and excellent mechanical properties. Herein, shellac nanoparticles (SNPs) were used as Pickering stabilizers to prepare SNPs-synergistic combination of cinnamaldehyde and citral (S CC ) Pickering emulsion (SNPs-S CC ). The SNPs-S CC was incorporating into chitosan (CS) to fabricate CS/SNPs-S CC film. Compared to the pure CS film, the tensile strength of the CS/SNPs-S CC film was enhanced by 58.89 %, while the moisture content, water solubility, water vapor permeability, and oxygen permeability were reduced by 52.89 %, 26.88 %, 45.28 %, and 40.51 %, respectively. Additionally, the CS/SNPs-S CC film demonstrated almost complete absorption of ultraviolet light in the wavelength range of 100–400 nm and was capable of complete biodegradation within 50 days. In vitro, antifungal tests revealed that the CS/SNPs-S CC film exhibited satisfactory antifungal activity against Aspergillus niger and Penicillium citrinum . Notably, the CS/SNPs-S CC film significantly extended the shelf life of bread by 5 days compared to the oriented polypropylene (OPP) film. Therefore, the CS/SNPs-S CC film holds potential for application as a novel active packaging material for bread preservation.

Bleached shellac, a widely used material in food processing and products, was deeply affected in terms of structures and properties by the bleaching method. In the present study, a marked difference was observed between the damage performances of sodium hypochlorite-bleached shellac (SHBS) and hydrogen peroxide-bleached shellac (HPBS). The main bleaching damage reactions of sodium hypochlorite were the addition of double bonds to generate chlorine and the oxidation of hydroxyl to form aldehydes or ketones. In the case of hydrogen peroxide, degradation of shellac resin was caused by the hydrolysis of ester bonds and the oxidation of hydroxyl groups to form aldehydes and ketones, as well as carboxylic acids with deep oxidation. Based on the structural characterization of shellac resin, the bleaching damages were affected by the bleaching agent via the oxidizable groups, such as the unsaturated double bonds, hydroxyl and aldehyde groups in cyclic terpenes, and fatty acid chains. The differences could be attributed to the action of sodium hypochlorite on the hydroxyl group of aldehyde or ketone. Conversely, hydrogen peroxide bleaching oxidized the hydroxyl group and aldehyde group to carboxylic acid and initiated the hydrolysis reaction of the ester bond of the shellac resin, leading to the degradation of the resin. Thus, understanding the mechanism underlying the bleaching damage could provide a scientific basis for the subsequent targeted regulation of bleaching damage.

As environmental awareness grows, developing non-toxic, environmentally friendly, and biodegradable water- and oil-resistant coating layers using bio-based materials for paper-based packaging has become a key field of research. In this work, sodium alginate (SA) and sodium carboxymethyl cellulose (CMC) were used as the oil-resistant coating layer, while shellac (LAC) and ethyl cellulose (EC) formed the water-resistant coating layer, to produce a water- and oil-resistant coated paper. The effect of the mass ratio of these materials on performance was analyzed, demonstrating that the interaction between SA and CMC enhances the compactness of coating, thereby improving oil resistance. Similarly, the addition of LAC to EC increases coating compactness, which improves water resistance. The resulting coated paper has excellent water resistance (Cobb value: 3.42 g/m 2 ) and oil resistance (Kit rating: 12/12) and shows no leakage after holding hot water and hot oil for 30 min, indicating good resistance to both. Additionally, the coated paper demonstrates good mechanical properties, thermal stability, biodegradability and recyclability. The materials used are widely available and low-cost, and the preparation method is straightforward, making this research highly valuable for advancing paper-based packaging materials.

In this research, the carvacrol (CAR) loaded cellulose acetate phthalate (CAP) /shellac (SH) films were prepared via electrostatic repulsion strategy and casting method. The CAP/SH-CAR films demonstrated excellent tensile strength , while also exhibiting good UV light barrier and thermal stability . The results showed that the addition of CAR significantly improved the barrier of the CAP film to water vapor and oxygen permeability. When the addition amount of CAR was 0.9 % (w/w) with respect to CAP content, the CAP/SH-CAR films exhibited good antibacterial activity and effectively reduced the growth of S. aureus and E. coli by approximately 47.9 % and 50.9 %, respectively. The presence of SH improved the retention rate of CAR in CAP/SH-CAR films, with the retention rate ranging from 45.2 to 56.8 %. Finally, the CAP/SH-CAR films were applied to preserve the mackerel fillets, indicating that the rate of freshness deterioration had been delayed and showing a good freshness preservation effect. Therefore, the CAP/SH-CAR films have the potential to be used as food packaging materials.

BACKGROUND Cinnamaldehyde (CA) is the main functional component of cinnamon essential oil, exhibits strong anti-microbial activity and safety. Shellac (SHL) nanoparticles enable the encapsulation and controlled release of CA while improving the physiochemical properties of chitosan (CS) films. To strengthen the anti-bacterial activity of SHL–CS films, CA–SHL nanoparticles were prepared by an anti-solvent precipitation method with Tween 80 as surfactant, and subsequently incorporated into CS film-forming solution. The resulting CA–SHL nanoparticle-filled CS coatings were then applied for the preservation of chilled beef. RESULTS The particle size of CA–SHL nanoparticles showed a unimodal distribution, decreasing with higher SHL content or lower CA concentration. Stable CA–SHL nanoparticles had relatively low zeta-potential values, indicating the stabilization effect of Tween 80. Incorporation of CA–SHL nanoparticles into CS films improved UV barrier properties, reduced water vapor permeability, improved pH corrosion resistance, and strengthened anti-bacterial activity. The CA–SHL nanoparticle-filled CS coatings extended the shelf life of chilled beef from 4 to 8 days. CONCLUSION The enhanced properties of CA–SHL nanoparticle-filled CS composite films highlight their strong potential for food packaging and preservation. © 2025 Society of Chemical Industry.

Shellac can be used as an ideal delivery vehicle to deliver and protect the hydrophobic quercetagetin; the barriers such as low acid stability and encapsulation efficiency, however, heavily impede the application of shellac. The purpose of this work is to prepare quercetagetin-loaded shellac-quaternized chitosan nanoparticles (Que-Sh-QCS NPs) to overcome these challenges. Herein, quaternized chitosan, with 14% degree of substitution, was successfully synthesized via a quaternization modification. The concentration of quaternized chitosan over 0.05% can prevent the aggregation of shellac nanoparticles at the acid. The encapsulation efficiency of quercetagetin obviously increased from 37.92 to 65.48% with the concentration of QCS varying from 0 to 0.05%. Meanwhile, Que-Sh-QCS0.05 NPs possessed good storage stability, antioxidant property, biocompatibility, and controlled release. Therefore, quaternized chitosan can improve the encapsulation efficiency and acid and storage stabilities of nutraceutical-loaded shellac nanoparticles, providing a new insight into the application of shellac in cosmetics, pharmaceuticals, and food.

Fluorides and long-chain aliphatic hydrocarbons are commonly used low surface energy compounds in superhydrophobic coatings. However, the potential toxicity of the former and the instability of the latter restrict the practical application of superhydrophobic coatings. In this study, a sustainable and environmentally friendly natural superhydrophobic coating was developed. This coating incorporates natural shellac and rosin to reduce surface energy and enhance adhesion, followed by the application of calcium carbonate nanoparticles (CaCO₃ nanoparticles) to modify white cardboard (WCB). Superhydrophobic white cardboard (SWCB) was successfully prepared. The water contact angle (WCA) of the coating is 155.3 ± 2°. SWCB exhibits excellent durability, retaining superhydrophobicity after 50 abrasion cycles, 45 tape stripping cycles, 30 min water impact, 30 knife strokes, and 7 days of outdoor exposure. It also demonstrates excellent self-cleaning properties, effectively repelling powders that mimic contaminants. In addition, when the coating is applied to paper cups, the paper cups exhibit excellent anti-adhesion properties. Therefore, this environmentally friendly superhydrophobic coating could offer a potential new approach to paper antifouling and food packaging.

To protect quercetin and address some of the barriers about shellac as a delivery carrier, we investigated the effects of sodium caseinate surface decoration on the formation, stability, and physiochemical properties of shellac nanoparticles (SNPs) for the first time. Herein, 0.3% caseinate was selected to prepare the quercetin-loaded shellac/sodium caseinate complex nanoparticles (SQCNPs), ensuring stable formation of nanoparticles and preventing irreversible aggregation of SNPs in acid. Fourier transform infrared spectroscopy and complex nanoparticle dissociation test indicated SQCNPs were fabricated based hydrophobic and hydrogen-bonding interactions among Que, shellac, and caseinate. Besides, the modification of sodium caseinate can address salt instability and low redispersibility and improve encapsulation efficiency of SNPs. Meanwhile, SQCNPs possessed good antioxidant capacity, low cytotoxicity and controlled release in simulated gastrointestinal digestion. In summary, this work might open up a new, green, and sustainable method to design a bioactive substance delivery system by employing shellac as a vehicle.

Hypothesis Shear-thickening micelles were mostly made of cationic surfactants , but shear-thickening was rarely reported in the zwitterionic/anionic surfactants. Since wormlike micelles were essential in shear-thickening systems, it should be common for the hybrid wormlike micelles formed by zwitterionic/anionic surfactants, and their fundamental features need to be clarified. Experiments The micellization of zwitterionic surfactant homologies alkyl dimethyl amidopropyl hydroxyl sulfobetaine (AHSB) and sodium dodecyl sulfate (SDS) in brine was studied, and various environmental factors were considered systematically. Light scattering, rheology, zeta potential , 1 H NMR and cryo-TEM techniques were employed to characterize the AHSB/SDS wormlike micelles. Findings AHSB/SDS hybrid wormlike micelles were formed in a wide x SDS region to endow them with apparent viscosities, in which the electrostatic and hydrophobic interactions between AHSB and SDS molecules were critical. AHSB with the longer tail, the higher c AHSB and c NaCl were advantageous to enhance the viscosity because of the longitudinal growth of wormlike micelles. The shear-thickening AHSB/SDS samples were commonly composed of unbranched wormlike micelles with various length, and the shear-induced alignment of wormlike micelles was the major cause as verified by cryo-TEM. Moreover, the quantitative relationships on the critical shear rate ɣ̇ c were established, and the activation energies were obtained from the temperature-dependent ɣ̇ c .

This study aims to utilize the synergistic effect between shellac nanoparticles (SNPs) and chitin nanocrystals (ChNCs) to construct Pickering emulsion (PE) with adjustable structures and properties for loading and delivering astaxanthin. The viscoelastic properties and stability of SNPs-ChNCs co-stabilized PE demonstrated markedly enhanced performance compared to systems stabilized individually by SNPs or ChNCs, particularly at a 5:1 SNPs/ChNCs ratio. Furthermore, the PE demonstrated notable pH responsiveness and salt ion resistance. Encapsulation performance evaluation revealed the SNPs/ChNCs co-stabilized system achieved enhanced payload parameters for astaxanthin. The S5C1 formulation demonstrated optimal encapsulation performance, achieving 92.1 % encapsulation efficiency (EE) with a loading capacity (LC) of 1.05 % under optimized conditions. Furthermore, the retention rate of astaxanthin exceeded 90 % after 21 days of storage and 8 h of UV irradiation. More importantly, the S5C1 PE showed a high free fatty acid (FFA) release rate and bioaccessibility of astaxanthin after simulated gastrointestinal digestion. This study provides a novel strategy for constructing pH-responsive PE and delivery system for functional active substances.

We present here a novel strategy for textile sample treatment, using galvanic displacement-based substrates, to identify anthraquinone dyes by surface enhanced Raman spectroscopy (SERS). This global procedure of SERS analysis, using several silver microparticles , in particularly those of dendritic shape, formed by reducing silver nitrate with zinc or copper, can be accomplished within 20 min. Compared to the synthesis of standard Lee-Meisel colloids, the preparation of silver dendrites provides a simple, fast and cost-effective route to produce reliable SERS substrates. The most fascinating feature is that the textile fibers analyzed are almost simultaneously covered with the substrates once the galvanic displacement reaction is triggered. This method was successfully applied to discriminating between alizarin and purpurin in a 6th-9th century samite with bird roundels, and carminic acid and laccaic acid in a 1740s chinoiserie brocade. However, as is the case with other silver substrates, the Raman signals of the insect dyes normally overlapped those of the plant dyes in the SERS profiles.
