“…However, the addition of carrot fibre into Na-alginate matrix enhanced the neat film structure against the water vapour diffusion by creating a barrier to the water molecules that were trapped in the matrix [19]. Similar results were observed in the literature, the micro cellulose or nanocellulose fibre addition to the neat alginate films decreased the WVP by creating a tortuous pathway to the water molecule transport [8,9,10,14,16]. Both of the filler contents acted as a barrier against water vapour transport; however the WVP of 1% CFF were significantly lower compared to the 5% CFF independent of the average film thickness ( Table 1).…”

“…Dried carrot pulp was crushed with a hammer mill (Brabender, SM3, Germany), and the fibres passing through 355 μm sieve was used in further extraction step. The cellulosic material extraction from carrot was carried out according to the study of Manzato et al [15], Sogut and Cakmak [16] with minor modifications. 8 g of dried carrot pulp with 1:30 (w/v) of 20% (w/v) NaOH was autoclaved at 135°C for 30 min (Alp, CL 40M, Japan).…”

“…The reduction of WVP with added fillers is associated with well dispersion of filler inside the matrix, although there is a limit for addition of cellulosic filler [6]. Over this limit, the filler may be agglomerated inside the matrix which leads to the stagnation of WVP reduction or even cause an increase the water vapour transmission [6,9,16]. Therefore, higher WVP of 5% CFF might be associated with the agglomeration of carrot fibre inside the matrix.…”

A lginate is naturally found in the structure of brown microalgae and composed of D-mannuronate and L-guluronate monomers [1, 2, 3]. It is water-soluble and biodegradable polysaccharide that has film-forming ability thus can be utilized in bio-based film formulations for food packing applications [1, 4, 5]. By having a hydrophilic matrix, alginate has a poor resistance to water vapour, therefore either cross linking with the polyvalent ions or reinforcement with cellulosic fibres for improving the water barrier and mechanical properties is recommended in the literature [1, 2, 6, 7, 8]. Nanocellulose addition to the Na-alginate based films at 5% rate improved the WVP and the tensile strength was also increased at the same nanocellulose enrichment level [9]. However, the cellulose fibres and cellulose nanowhiskers that were extracted from mulberry pulp addition to Na-alginate based films had different impact on mechanical and water barrier properties [8]. The cellulose nanowhiskers at each reinforcement level had higher tensile strength and elastic modulus compared to the control film, while the cellulose fibre addition had a negative effects on these mechanical parameters. Both of these cellulosic sources did not impro-Article History:

Bu çalışmanın amacı, polikaprolaktonun (PCL), kitosan (CH) film üzerine kaplandığında, PCL ikinci katmanının filmlerin fiziksel, antioksidan ve antimikrobiyal özellikleri üzerine etkisini değerlendirmektir. D-limonen (%5, w/w) ve nanoselüloz (N) (%2, w/w), CH film çözeltilerine ilave edilmiş ve daha sonra gıda ambalajlama uygulamaları için PCL ile kaplanarak aktif çift katmanlı filmler elde edilmiştir. Film örnekleri optik analiz, geçirgenlik testleri, antioksidan ve antimikrobiyal aktivite testleri ile karakterize edilmiştir. CH üzerindeki PCL katmanı filmlerin su buharı geçirgenliğini geliştirirken, çift katmanlı filmler daha opak olarak gözlenmiştir. CH filmlere D-limonen ilave edilmesi, film örneklerinin su buharı ve ışık geçirgenlik değerlerinde azalışa neden olmuştur ancak bu azalış iki katmanlı filmlerde gözlenen azalış kadar yüksek değildir. D-limonen içeren film örnekleri hem antioksidan kapasite hem de seçilen bakterilere karşı antimikrobiyal aktivite göstermiştir.

This study investigated the influence of grape stalk (GS) from the Bordo grape variety (Vittis labrusca L.) as a reinforcing agent, and pink pepper (Schinus terebinthifolius Raddi) extract (PPE) as an antioxidant, in cassava starch (CS)‐glycerol (GLY) films. The developed biodegradable films were characterized according to structural, barrier, mechanical, antioxidant and optical properties, as well as biodegradability and compared to both the control and blank films. Films containing a high GS content exhibited a significant increase in tensile strength (TS) values by 73%, whereas the films containing a high PPE content exhibited an important increase elongation (ELO) values by 20%, comparing to the control film (CO). The films containing 5.52% v/v of PPE presented an improving on antioxidant activity and barrier properties, leading DPPH and ABTS percentual radical scavenging activity by 51.79% and 58.18%, and decreasing water vapor permeability and solubility by expressive values of 34.11% and 79.43%, respectively. According to the results obtained in this study, the films using GS and PPE exhibited valuable characteristics and are an alternative for applications as a promising biodegradable packaging material.
