In this work, new composite film based on starch and nano clay particles was provided. The nano composite film was loaded by methyl orange (MO) and bromocresol green (BG) indicators. Two type films, including starch‐nano clay‐methyl orange (SCMO) and starch‐nano clay‐bromocresol green (SCBG) were provided. Some properties of provided films, including solubility in water, moisture uptake, water vapor permeability, FT‐IR, and scanning electron microscopy were studied. According to the results, MO and BG were loaded between starch and nano clay particles physically and clay particle size was between 40 and 100 nm. Finally, the SCMO and SCBG simultaneously were improvised in the milk bottle. According to the color change of indicators in the different pH (MO [3.1‐4.4] and BG [3.8‐5.4]), the fabricated films were used for determination of milk spoilage in a milk bottle. The best advantage of fabricated SCMO and SCBG films is that the indicators do not release into the milk by exposing with the milk. The milk pH is changed during the storage time (from 6.7 to the 4), and in the low pH, the milk is spoiled so the fabricated film smartly could show the spoilage of milk by color changing.

“…So, we concluded that during the formation of the cellulose–SM‐MMT nanocomposite foams, new hydrogen bonds were formed between the cellulose and SM‐MMT nanoparticles. In general, the FTIR spectra confirmed the presence of SM‐MMT in the cellulose matrix and the interactions between the SM‐MMT and cellulose …”

International audienceIn this work, an extensive study was carried out on the preparation and characterization of nanoclay biocomposites based on cellulose to substitute for synthetic polymer foam trays as food-packaging materials. The preparation stage was performed via a dissolution/regeneration route followed by drying with lyophilization. The chemical, physical, mechanical, and morphological properties of the prepared composite foams were characterized by several methods, including scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, mechanical tests, density, and color analyses. The obtained results indicate that the presence of nanoclay in the cellulose matrix caused more uniformity in the structure of the foams. Also, an increase in the nanoclay content resulted in a higher density, compressive strength, and Young's modulus. The achievements from this study suggest that the prepared cellulose nanocomposite foam could be a potential alternative to commercial synthetic foams for packing food products

“…Clays is also reported to improve the mechanical strength of biopolymers (Alexandre et al 2009). Incorporation of NC in polymer formulations enhances the tortuosity of the diffusive path for a penetrating molecule, and changes the molecular mobility, which enhances the thermal and mechanical properties amongst other advantages (Cyras et al 2008;Marcelo Slavutsky et al 2012). The cost was not evaluated at this stage, but is estimated to be quite low on a kg of fruit basis and well worth the protection it provides.…”

Some physical properties like Gas barrier, thermal stability, and mechanical properties and brittleness of pure biopolymers film are inadequate for food packaging. The functional properties of quince seed mucilage-based films were enhanced by addition of nanoclay (NC) (Cloisite 30B). Edible films were cast from heated aqueous solutions of quince seed (10% w/w) and NC (0.5%, 1%, 1.5%, and 2% w/w of quince seed). The effect of NC was studied in terms of tensile properties, water vapor permeability (WVP), oxygen permeability, and glass transition temperature (Tg) of the nano composite films. In films containing NC, ultimate tensile strength enhanced to 22 MPa, and elongation increased from 2.48% to 6.5%. The addition of NC also improved gas barrier properties of the films. In films containing 2% NC, WVP decreased from 6.69 × 10−7 g·m−1·h−1·Pa−1 to 1.10 × 10−7 g·m−1·h−1·Pa−1 and oxygen permeability declined to 13.68 mL·day·m−2. NC also influences glass transition temperature significantly. The study demonstrated that the properties of quince seed mucilage edible films can be significantly improved using NC as reinforcement.
