This research focused on the development of carrageenan based biodegradable films incorporated with olive leaves extract (OLE). OLE microbial inhibition and its total phenolics (TP) were evaluated. Carrageenan films were produced by casting technique and were characterized by thickness, water vapor permeability (WVP), color, mechanical properties, and infrared spectroscopy. In order to apply as lamb meat packaging, the antimicrobial effect of the films was investigated. Results showed that OLE inhibited E. coli growth and presented excellent TP (41.40 mgGAE/g). Thicknesses of the film with OLE (CAR‐OLE) were approximately 28% higher than film without OLE. Addition of OLE reduced the WVP by approximately 54%. CAR‐OLE was less resistant to breakage and more flexible showing darker color. FTIR showed interaction of carrageenan with OLE. Results revealed that CAR‐OLE promoted 167‐fold reduction in initial count of aerobic mesophiles indicating shelf‐life extension of lamb meat and promising use as antimicrobial food packaging. 相似文献

Food packaging materials are traditionally expected to contain foodstuffs and protect them from deteriorating agents. Although petroleum‐derived polymers have been widely used for this purpose, the rising concern with their nonrenewable and/or nonbiodegradable nature paves the route for the development of greener alternatives, including polysaccharides and polypeptides. The use of these food‐grade biomacromolecules, in addition to fruits and vegetables, provides edible packaging with suitable physical‐mechanical properties as well as unique sensory and nutritional characteristics. This text reviews the chronological development pathway of films based on fruit and vegetable purees, pomaces, and extracts. Recent advances are extensively reviewed with an emphasis on the role that each film component plays in the resulting materials, whose production methods are examined from a technical standpoint and essential properties are compiled and contrasted to their conventional, synthetic counterparts. Finally, this comprehensive review discusses advantages and limitations of edible films based on fruits and vegetables. 相似文献

Concerns on environmental waste problems caused by non-biodegradable petrochemical-based plastic packaging materials as well as the consumer's demand for high quality food products has caused an increasing interest in developing biodegradable packaging materials using annually renewable natural biopolymers such as polysaccharides and proteins. Inherent shortcomings of natural polymer-based packaging materials such as low mechanical properties and low water resistance can be recovered by applying a nanocomposite technology. Polymer nanocomposites, especially natural biopolymer-layered silicate nanocomposites, exhibit markedly improved packaging properties due to their nanometer size dispersion. These improvements include increased modulus and strength, decreased gas permeability, and increased water resistance. Additionally, biologically active ingredients can be added to impart the desired functional properties to the resulting packaging materials. Consequently, natural biopolymer-based nanocomposite packaging materials with bio-functional properties have a huge potential for application in the active food packaging industry. In this review, recent advances in the preparation of natural biopolymer-based films and their nanocomposites, and their potential use in packaging applications are addressed. 相似文献

The incorporation of nanomaterials into a range of polymeric materials shows great potential for developing new active food packaging systems. Although there are many suggested benefits of nanoparticles (NPs) in food packaging, there are also potential risks due to the possibility of such particles migrating into foodstuffs. This has obvious implications for human health and it may also negatively impact on marketing and consumer confidence. This review focuses on 2 particular types of nanomaterials: nanoclays and nanosilver, with a view to examining the effects of these on system mechanical properties (nanoclays) and antimicrobial efficacy (nanosilver). It further reports on the various migration studies, techniques for characterization, and measurement of NPs as well as the potential migration of NPs from packaging into foodstuffs. Assessment of the literature to date suggests there is an urgent need for further research in order to devise better NP detection methods and to determine the likelihood of their migration from packaging materials into foodstuffs. 相似文献

Significant interest has emerged in the introduction of food packaging materials manufactured from biodegradable polymers that have the potential to reduce the environmental impacts associated with conventional packaging materials. Current technologies in active packaging enable effective antimicrobial (AM) packaging films to be prepared from biodegradable materials that have been modified and/or blended with different compatible materials and/or plasticisers. A wide range of AM films prepared from modified biodegradable materials have the potential to be used for packaging of various food products. This review examines biodegradable polymers derived from polysaccharides and protein-based materials for their potential use in packaging systems designed for the protection of food products from microbial contamination. A comprehensive table that systematically analyses and categorizes much of the current literature in this area is included in the review. 相似文献

This study focuses on the modification of starch using cold plasma (CP) for 0, 30, 60, and 90 seconds. The prepared films are characterized (i.e., thickness, water vapor permeability, intrinsic viscosity, solubility in water, and moisture absorption). The thickness, water vapor permeability (WVP), intrinsic viscosity, solubility in water (SW), moisture absorption (MA), and roughness of the modified starch films increases with longer plasma-processing time (PPT). Conversely, the contact angle and density of the films decreases. However, there are no significant changes observed in the moisture content and UV–Vis spectrum of the cold plasma-irradiated starch (CPS) films. The CP treatment has some effects on the mechanical properties of the films, such as elongation at break and tensile energy to break, but the tensile strength remains unaffected by PPT. Additionally, CP has a significant impact on the visual properties of CPS films, with increased lightness and white index with longer PPT. Most of the observed characteristics are attributed to physical changes in the starch structure caused by etching. Overall, CP is considered a green, and easy for modifying starch-based packaging materials. However, it is not an effective method for reducing the sensitivity of the films to moisture at the applied PPT. 相似文献

Polyethylene composites containing AgionTM commercial silver ion filler at three different percentage fill rates (0.5, 1.0 and 2% w/w) and polyethylene composites containing laboratory produced silver nanoparticles (Agnps) at two different percentage fill rates (0.1 and 0.5% w/w) underwent migration tests according to Commission Regulation (EU) No. 10/2011. Migrated silver in the two simulants (acidified water with 3% acetic acid and distilled water) was quantified using two techniques: inductively coupled atomic emission spectroscopy (ICPAES) and Hach Lange spectroscopy. The former had higher sensitivity with mean silver migration from Agion composites (n = 12) ranging from < 0.001 to 1.50 × 10?2 mg l–1. Mean silver migration from Agnps composites ranged from 4.65 × 10?2 to 0.38 mg l–1 and 8.92 × 10?2 and 5.15 × 10?2 mg l–1 for Hach Lange spectrophotometry and ICPAES, respectively. Both percentage fill rate in the composite and the simulant type, as factors, were found to be significant in both silver migration from Agion (p < 0.0001 and < 0.01, respectively) and Agnps (p < 0.05 and < 0.01, respectively). Transmission electron microscopy (TEM) imagery showed differences in size distributions and morphology of particles (shape and degree of agglomeration) before and after migration. PE composites containing 0.5% Agion, simulating contact with non-acidic foods, was the only scenario that did not exceed the permitted migration level of non-authorised substances given in EU 10/2011. This study illustrates the need for careful engineering of the composite filler system to conform to limits with cognisance of food pH and percentage fill rate. 相似文献

The biocompatible active films were prepared based on nanochitosan (NCh) containing free and nanoliposome caraway seed extract (NLCE). The produced films were characterized by physico-mechanical, barrier, structural, color, antimicrobial, and antioxidant properties. The average particle size of NLCE was 78–122 nm, and the encapsulation efficiency (EE%) was obtained 49.87%–73.07%. Nanoliposomes with the lowest size and the highest encapsulation efficiency were merged with the film samples. NCh/CE3% and NCh/NLCE3% films had higher stability compared to other films and showed the highest antimicrobial activity (3.68 mm inhibition) and radical quenching capacity (51%), respectively. Likewise, biodegradable active films containing nanoliposomes had lower antimicrobial potential and higher antioxidant capacity than films containing free extract with similar concentration. The Fourier-transform infrared spectroscopy (FTIR) results revealed new interactions between NCh and nanoliposomes. Scanning electron microscopy (SEM) investigation also exhibited a homogenous structure and nearly smooth surface morphology with a good dispersion for NCh/NLCE films. Despite an increase in yellowness (b value) and a decrease in whiteness (L value) index, the incorporation of nanoliposomes within the NCh films improved the mechanical flexibility (from 10.2% to 15.05%) and reduced water vapor permeability (WVP) (from 14.2 × 10–12 g/m·s·Pa to 11.9 × 10–12 g/m·s·Pa). Today, due to the growing trend toward natural ingredients, the use of nanoparticles derived from plant derivatives has expanded in the food industry owing to their antimicrobial and antioxidant properties. 相似文献

The past decade has seen nanotechnology progressively being adopted by the food industry. Its wide application in food packaging has redefined conservative food packaging with active and intelligent packaging. Nanomaterials do not only influence food quality and safety but also offer health-related benefits. Selenium nanoparticles (SeNPs) have been preferred in recent years because of their high biological activity. However, they are generally synthesised using physicochemical methods which are associated with toxicity. In the past decade, efforts have been directed towards advancement of green synthesis of SeNPs to minimise hazardous by-products. The antioxidant and biocidal effects of SeNPs are generally investigated by direct contact between the oxidisable matter and/or test organisms. Lately, there is focus on the effect SeNPs incorporated into packaging films. This paper will review developments on SeNPs synthesised via plant extracts from the year 2010 to present and their potential application in active food packaging. 相似文献

The inclusion of probiotics into the packaging films has emerged as a novel approach to provide edible packaging with new functionalities. In this study, probiotic films were developed by embedding four different probiotics (Lactobacillus casei, Bifidobacterium bifidum, Lactobacillus acidophilus, and Lactobacillus rhamnosus) into citrus pectin films and their viability was checked at 25 and 4 °C for 30 days. A reduction of 0.44, 1.04, 0.32, and 1.0 log CFU g−1 was observed in probiotic films containing L. casei, B. bifidum, L. acidzophilus, and L. rhamnosus respectively during drying process of film’s formation. The viability of all probiotics (except B. bifidum) was decreased from 109 to 106 CFU g−1 in 30 days storage at 25 °C. Whereas, only 2 log reduction was observed for films stored at 4 °C during 30 days. The physical and optical properties of the films were affected slightly by inclusion of bacterial cells. The presence of live cells in films made them less resistant to elongation and less stretchable. All bacterial films inhibited the growth of L. monocytogenes by 1.5 logs compared to control. The results suggest the entrapment of probiotics in pectin can be used as an effective packaging technology for ensuring food safety. 相似文献

ABSTRACT: In response to the dynamic changes in current consumer demand and market trends, the area of Active Packaging (AP) is becoming increasingly significant. Principal AP systems include those that involve oxygen scavenging, moisture absorption and control, carbon dioxide and ethanol generation, and antimicrobial (AM) migrating and nonmigrating systems. Of these active packaging systems, the AM version is of great importance. This article reviews: (1) the different categories of AP concepts with particular regard to the activity of AM packaging and its effects on food products, (2) the development of AM and AP materials, and (3) the current and future applications of AM packaging. 相似文献

The ultimate goal of new food packaging technologies, in addition to maintaining the quality and safety of food for the consumer, is to consider environmental concerns and reduce its impacts. In this regard, one of the solutions is to use eco-friendly biopolymers instead of conventional petroleum-based polymers. However, the challenges of using biopolymers in the food packaging industry should be carefully evaluated, and techniques to eliminate or minimize their disadvantages should be investigated. Many studies have been conducted to improve the properties of biopolymer-based packaging materials to produce a favorable product for the food industry. This article reviews the structure of biopolymer-based materials and discusses the trends and challenges of using these materials in food packaging technologies with the focus on nanotechnology and based on recent studies. 相似文献

ABSTRACT: Low-density polyethylene film was coated with a solution containing a high-molecular-weight or low-molecular-weight methylcellulose and hydroxypropyl methylcellulose. Films contained 10000, 7500, 5000, 2500, or 0 IU/cm2 nisin. Film samples were placed into peptone water, and 10-μL samples were removed and placed onto spiral plated lawns of Listeria monocytogenes . Zones of inhibition were measured using a caliper. Films containing 5000, 7500, and 10000 IU/cm2 nisin inhibited L. monocytogenes after 30 min; films with 7500 and 10000 IU/cm2 nisin inhibited L. monocytogenes after 60 min and 8 h, respectively. No zones of inhibition were observed after 24 h and 4 d for all films. After 8 d, zones of inhibition were observed for films with all levels of nisin except 2500 IU/cm2. Films with 0 and 2500 IU/ cm2 nisin did not produce zones of inhibition throughout the study. Molecular weight of the cellulose-based carrier had no effect on inhibition of L. monocytogenes. A standard curve of inhibition was developed using solutions of 10000, 7500, 5000, 2500, or 0 IU/cm2 nisin applied directly to lawns of L. monocytogenes . The amount of inhibition using a direct application of a solution was 25% to 50% more effective for inhibition of L. monocytogenes compared with the coated film samples. Overall, the coated film samples were effective for inhibition of L. monocytogenes , particularly when 7500 and 10000 IU/cm2 nisin were used, but the release of nisin was not controlled and did not provide consistent inhibition throughout the 8-d study. 相似文献
