Abstract Paper is an environmentally friendly, recyclable material whose main material is cellulose, which can be obtained from all kinds of trees and plants, used as writing, printing and packaging material. Due to its structural properties, papers are not resistant to temperature and humidity, as well as problems with ink transfer with its porous structure and experienced negative printability properties. In recent years, especially the growth of the packaging industry has increased the demand for papers with improved printability properties. In order to obtain better printability properties from papers, some processes can be performed in paper production, as well as some surface treatments after production. These processes are paper coating, sizing and calendering. Paper coatings are generally water-dispersed coating solutions with one or more pigments, binders and certain additives to improve the desired properties. With these processes, by filling the gaps between the pores of the paper, a shapely and smooth surface is obtained and good printability is obtained together with the optical and physical properties of the papers. In this study, the interactions and printability properties of different types of pigments with xanthan gum binder were investigated by preparing paper coating formulations using calcium carbonate, barite and talc pigments and xanthan gum as binder. As a result, xanthan is a good coating binder and CaCO 3 {\mathrm{CaCO}_{3}} from the compared pigments is the most suitable compared to the other 2 pigments, considering all the studied areas.

The results of the infestation by maize weevil, Sitophilus zeamais (Coleoptera, Curculionidae) in various packages filled with pasta are presented. Three different types of packaging were used, i.e. two paper tubes (a novel one laminated with bio-based polyethylene and one without lamination) and a commercially available polypropylene pillow pouch packaging. Material properties such as moisture and water resistance and compressive strength were analysed. The results obtained showed that adult maize weevils revealed significant preferences to penetrate the pasta packaging through the already existing holes that were present in the polypropylene packaging, whereas no infestation was observed inside the paper tube packaging. The study showed that the shape and construction, e.g. tube packaging with an innovative bio-polyethylene film, is very effective against insect infestation and mechanical overload.

Main Material

Recently, lightweight wall systems have been used mainly due to the appearance of flexible buildings, but EPS, which is flammable, is the main material. The damage caused by toxic gas in fire is recognized as a problem. NaOH, KOH and Ca(OH)2 were used as alkali stimulants and the properties of the matrix were evaluated according to the addition ratio of alkali stimulants. The addition of an alkali stimulant increases the pH and increases the alkali activity of the blast furnace slag, thereby changing the performance of the matrix. When NaOH and KOH are used as alkali stimulants, the density of the cured product is low and the incidence of the internal void of the cured product is high. When Ca(OH)2 is used as an alkali stimulant, it shows the best performance when measuring pH, setting time, and strength. This seems to be due to the ionization degree of the (OH) group. However, the incidence of voids was the lowest.

The aim of the study is to reveal the differences in the packaging priorities used in food products of women living in rural and urban areas. The data used in the research were obtained by questionnaire technique. For sample size, the proportional sampling method was used. 70 in Selçuklu district of Konya and 70 in Çumra district, in total 140 questionnaires were determined. The data obtained from the survey results were transformed into tables according to rural and urban women. As a result; For women living in rural and urban areas, the color and shape of the packaging are effective in taking and distinguishing the product. Rural women prefer more relaxing colors in their packaging color preferences, while women living in urban areas prefer more stimulating colors. Women living in both rural and urban areas are aware of the information written on the packaging. As a result, companies in the packaging industry should determine the packaging material and color according to the communities they address.

Background: Cajá-manga is an exotic fruit, source of compounds that have antioxidant activity, such as pro-vitamin A and carotenoids. Objective: Thus, the objective of the present study was to develop an efficient microencapsulation process for cajá-manga pulp by different types of encapsulating agents (maltodextrin and xanthan gum), ratio pulp/carrier agents (1:2 or 1:5), and the drying technology (lyophilization and spray dryer). Methods: Physicochemical analysis, phenolic compounds, carotenoids, antioxidant activity and microcapsule morphology were performed. Results: The cajá-manga and its microcapsulas can be considered source of phenolic compounds, carotenoides and antioxidants. The morphology showed differences between the both drying methods, with encapsulation efficiency greater than 70% in 1:2 (w/w) ratio, and efficiencies around 40% with 1:5 (w/w) pulp and carrier agent. Conclusion: The use of maltodextrin and xanthan gum showed to be viable in the spray dryer and lyophilization drying processes.

Rheology Modifier

The rheological and dewatering behavior of an aqueous pigmented coating system not only affects the machine runnability but also affects the product quality. The current study describes the use of natural hydrocolloids derived from citrus peel fibers as a rheology modifier in paper coating applications. The results were compared with carboxymethyl cellulose (CMC) in a typical paper coating system. Water retention of the coating formulation was increased by 56% with citrus peel fibers compared to a default coating, and it also was higher than a CMCcontaining coating. The Brookfield viscosity of paper coatings was found to increase with citrus peel fibers. Compared to CMC, different citrus peel fibers containing coating recipes were able to achieve similar or higher water retention values, with no change or a slight increase in viscosity. Coatings were applied on linerboard using the Mayer rod-coating method, and all basic properties of paper were measured to assess the impact of citrus peel fiber on the functional value of the coatings. Paper properties were improved with coated paper containing citrus peel fibers, including brightness, porosity, smoothness, surface bonding strength, and ink absorption.

Modified canna starch by Heat Moisture Treatment (HMT) and xanthan gum (GX) showed had potential used in the formulation of gluten-free breads. This study aimed to explore the phyiscals and sensory caharacteristics of gluten-free breads from some types of modified canna starch. The main material was some types of modified canna starch. The study was applied Completely Randomized Design with one treatment factor of starches type (HMT-GX and HMT modified canna starches, natural canna starch with and without 1.5% of xanthan gum addition, corn starch, and wheat flour). While the characteristics of bread determined include: specific volume, color, texture, ratio between height and diameter of bread, and sensory. The results showed that the best treatment based on physical and sensory characteristics was produced using HMT-GX modified canna starch. The characteristics of gluten free bread produced have a specific volume of 2.85 ± 0.017 cm3/g, color (L *, a *, b * 75.13, +9.370; +29.40, respectively), texture of 109.03 ± 7.50 gf, bread high and diameter ratio of 0.74, hedonic score for taste, color, texture and aroma respectively 5.34; 5.46; 5.56, and 5.80 repectively (range of hedonic values from 1 = very dislike to 7 = very like).
