“…Furthermore, improvements to thermal stability and mechanical properties were observed in thermoplastic amylose/kaolin composites (Huang et al 2006). Different types of proteins are used as biodegradable materials in packaging (Khwaldia et al 2010). Among the proteins, wheat is considered to be a valuable candidate for packaging applications because of its low price, biodegradability, renewability, and good film forming and adhesive/cohesive properties (Türe et al 2013).…”

Effects of nano-kaolin incorporation into semolina films on the physical, mechanical, thermal, barrier and antimicrobial properties of the resulting bio-nanocomposite films were investigated. The properties included crystal structure (by X-ray diffraction), mechanical resistance, color, Fourier transform infrared spectra, decomposition temperature, water-vapor permeability (WVP), oxygen permeability (OP), and antimicrobial activity against Staphylococcus aureus and Escherichia coli. Kaolin was incorporated into biofilms at various amounts (1, 2, 3, 4, and 5 %, w/w total solid). All films were plasticized with 50 % (w/w total solid) combination of sorbitol/glycerol at 3:1 ratio. The incorporation of nanokaolin into semolina films decreased OP and WVP. The moisture content and water solubility of the films were found to decrease by nanokaolin reinforcement, and mechanical properties of films were improved by increasing nanokaolin concentration. Tensile strength and Young's modulus increased from 3.41 to 5.44 MPa and from 63.12 to 136.18, respectively, and elongation-at-break decreased. The films did not exhibit UV absorption. In conclusion, nanokaolin incorporation enhanced the barrier and mechanical properties of semolina films, indicating the potential application of these bio-nanocomposites in food-product packaging.

“…Yüzey tutkallama maddesi olarak lateks tipi tutkallar (Polivinil alkol v.b.) sentetik tutkal olarak kullanılırken, doğal ve çevre dostu tutkal olarak nişasta ve karboksimetil selüloz kullanılmaktadır [8]. Sodium karboksimetil selülozun (CMC) yaş mukavemet kimyasalı verimini arttırdığı, diğer kağıt proseslerinde ise kuru mukavemet değerlerine katkı sağladığı ve kağıt yü-zey özelliklerini geliştirerek basılabilirlik özelliklerini arttırdığı en bilinen temel özellikleridir [9].…”

Politeknik Dergisi, 2017; 20 (4) : 985-991 Journal of Polytechnic, 2017; 20 (4) Comparison of into the Effects of Ultraviolet Flexo Ink on Printability of The Paperboards Coated With Carboxymethyl Cellulose and Polyvinyl Alcohol ABSTRACTThe aim of this work is to compare the effect of Ultraviolet (UV) flexo inks used in the paperboards coated with carboxymethyl cellulose (CMC) and Polyvinyl alcohol (PVOH) on the printing quality. The study was made at two stages. At the first one, the surface sizing prepared using 5 % of carboxymethyl cellulose, 5 and 10 % of PVOH was coated on the surface of base paperboard and fully dried at the room temperature. The surface roughness, contact angles, cobb and gloss values of the coated base paperboard were measured. At the second stage, the test printings using both water based flexo ink and UV flexo ink on the coated base paperboard were carried out. The print density, L*a*b* and gloss values (printed) were evaluated on the printed surface areas in the coated base paperboards. The obtained results showed that the surface smoothness of the paperboards coated by PVOH was better than the one coated using CMC, but their resistance to wetting was smaller. The printing quality between the paperboards coated by PVOH or CMC was not significantly different. The print density, delta gloss and chroma values of printings attained using UV ink were higher compared to water based ink, revealing that the UV inks increased the printing quality.

“…Assim como a diversidade dos antimicrobianos, os polímeros utilizados podem ser divididos em dois grupos: os biodegradáveis e os materiais plásticos derivados de petróleo, que tem despertado uma crescente preocupação global, devido ao seu descarte inadequado e acumulação em ambientes naturais, desta forma, existe a intenção de substituir parcialmente esse tipo de material por polímeros biodegradáveis (KHWALDIA et al, 2010). Na seleção de um composto antimicrobiano, deve ser considerada a eficácia contra os microrganismos alvo e também a possível interação entre os componentes do biopolímero e o composto antimicrobiano.…”

RESUMOAs embalagens destinadas aos alimentos, atualmente, possuem finalidades além da proteção do produto, podendo interagir com os alimentos proporcionando a eles características desejadas, é o caso das embalagens ativas. O objetivo desta prospecção tecnológica, foi realizar um levantamento do número de documentos destinadas a utilização de embalagens incorporadas com agentes antimicrobianos aplicados à alimentos. As buscar foram realizadas através do ESPACENET, utilizando as seguintes nomenclaturas packing, food e antimicrobial. A Coréia do Sul é o país com maior número de patentes e inventores independentes são os maiores depositantes. O polímero mais utilizados é o Polietileno e antimicrobianos sintéticos são os mais empregados. Existem poucas patentes acerca do tema, com isso abre-se uma nova perspectiva de pesquisa e inovação.Palavras-chave: Embalagem ativa. Antimicrobianos. Alimentos. TECHNOLOGICAL PROSPECTION OF PATENTS ON THE USE OF ANTIMICROBIAL FOOD PACKAGING ABSTRACTPackages intended for food currently possess purposes besides protection of the product, in the case of active packaging they can interact with the food introducing the desired characteristics. The objective was to carry out a survey of the number of patents using packaging with antimicrobial agents applied to food. The results indicate that South Korea is the country with the highest number of patents and that individual inventors are the largest depositors. Polyethylene is the most widely used polymer and synthetic antimicrobials are the antimicrobial agent more used. There are few patents on the subject, which opens up a new perspective of research and innovation.
