Hydrocolloids are commonly used in canned pet food. However, their functional effects have not been quantified in this food format. The objective was to determine the effects of select hydrocolloids on batter consistency, heat penetration, and texture of canned pet food. Treatments were added to the formula as 1% dextrose (D) and 0.5% guar gum with 0.5% of either dextrose (DG), kappa carrageenan (KCG), locust bean gum (LBG), or xanthan gum (XGG). Data were analyzed as a 1-way ANOVA with batch as a random effect and separated by Fisher’s LSD at p < 0.05. Batter consistency (distance traveled in 30 s) thickened with increasing levels of hydrocolloids (thinnest to thickest: 23.63 to 2.75 cm). The D treatment (12.08 min) accumulated greater lethality during the heating cycle compared to all others (average 9.09 min). The KCG treatment (27.00 N) was the firmest and D and DG (average 8.75 N) the softest with LBG and XGG (average 15.59 N) intermediate. Toughness was similar except D (67 N·mm) was less tough than DG (117 N·mm). The D treatment showed the greatest expressible moisture (49.91%), LBG and XGG the lowest (average 16.54%), and DG and KCG intermediate (average 25.26%). Hydrocolloids influenced heat penetration, likely due to differences in batter consistency, and affected finished product texture.

Objective: The main aim of the present research was to develop an oral fast dissolving polymeric film (FDF) with good mechanical properties, faster disintegration and dissolution when placed on the tongue.Methods: Eletriptan hydrobromide is prescribed for the treatment of mild to a moderate migraine. The polymers selected for preparing films were Pullulan, Maltodextrin (MDX), Acacia, Sodium alginate (SA), Locust bean gum (LBG), Guar gum (GG), Xanthan gum (XG), Polyvinyl alcohol (PVA), Polyvinyl pyrrolidine (PVP), Hydroxyl propyl methyl cellulose (HPMC) E5, and HPMC E15. Twelve sets of films FN1–FN12 were prepared by solvent casting method with Pullulan and combination of Acacia, MDX, SA, LBG, GG, XG, PVA, PVP, HPMC E5 and HPMC E15. Five sets of films FS1–FS5 were prepared using synthetic polymers like PVA, PVP, HPMC E5 and HPMC E15.Results: From all the prepared polymer formulations, FN2, FN8, and FS3 were selected based on disintegration time, and drug release and amongst this three FN2 was optimised based on its disintegration time (D. T). The percent drug release of the optimised film was compared with the percent release of the pure drug.Conclusion: The optimised formulation had a D. T of 16 s and a percent drug release of 97.5% in 10 min in pH 6.8 phosphate buffer and 100.6% drug release in 10 min in 0.1N HCl.

Gluten-free bread formulations based on small broken rice berry using various types of hydrocolloids (xanthan gum, guar gum, and locust bean gum) at different concentrations (0, 1, 1.5, and 2 g/100 g) were tested in this study. The effects of hydrocolloid addition on the pasting properties of flour were also investigated, including the quality parameters of the breads. The pasting properties of small broken rice berry flour incorporated with guar gum were most affected. Gluten-free bread containing hydrocolloid showed improved qualities in terms of loaf specific volume, texture, sensory values, and microstructure. A 1 g/100 g of hydrocolloid addition was sufficient to improve the physical and chemical qualities of bread. The highest score of all attributes from the sensory evaluation was obtained by gluten-free bread containing 1 g/100 g guar gum.

Abstract The ability to create diverse structures and studies on the effect of the aerated structure on selected properties with the use of freeze-dried gels may provide knowledge about the properties of dried foods. Such gels can be a basis for obtaining innovative food products. For the gel preparation, 3 types of hydrocolloids were used: low-methoxyl pectin, a mixture of xanthan gum and locust-bean gum, and a mixture of xanthan gum and guar gum. Gels were aerated for 3 and 7 min, frozen at a temperature of −45°C 2 h−1, and freeze-dried at a temperature of 30°C. For the samples obtained, structure, porosity, shrinkage, rehydration, and colour were investigated. It was shown that the type of the hydrocolloid and aeration time influence the structure of freeze-dried gels, which determines such properties of samples as porosity, shrinkage, density, rehydration, and colour. The bigger pores of low-methoxyl pectin gels undergo rehydration in the highest degree. The delicate and aerated structure of gels with the mixture of xanthan gum and locust-bean gum was damaged during freeze-drying and shrinkage exhibited the highest value. Small pores of samples with the mixture of xanthan gum and guar gum were responsible for the lower rehydration properties, but the highest porosity value contributed to the highest lightness value.

Abstract Many wet pet foods include carbohydrate ingredients that enhance viscosity for container filling or provide structure after processing. These gums and gels can cause differences in commercial sterilization as well as visible changes in product quality. Therefore, the objective was to determine the effect of different gums and gelling carbohydrates on the appearance, texture, and thermal processing metrics of wet pet foods. Treatments were added to a chicken-based formula as 1% dextrose (NH), 0.5% guar gum and 0.5% dextrose (GG), 0.5% guar gum and 0.5% kappa carrageenan (KCGG), 0.5% guar gum and 0.5% locust bean gum (LBGGG), or 0.5% guar gum and 0.5% xanthan gum (XGGG). Batters were analyzed for pH, water activity, and consistency with a Bostwick consistometer as a crude indication of viscosity. Thermocouples were placed in cans to measure cold-spot temperatures for Fo and cook-value calculations. Replicate batches (n = 3) included each treatment and were commercially sterilized in a still retort at 121 ℃ and 144.79 kPa. Can vacuum and product color (colorimetry) were measured after cans cooled to ambient temperatures. Treatments were analyzed as a 1-way ANOVA with batch as a blocking factor. Means were separated by Fisher’s LSD using statistical analysis software (GLIMMIX; SAS 9.4). Batter consistency thickened (P &lt; 0.05) with increasing levels of gums and gelling carbohydrates. Batter pH, batter water activity, and can vacuum were not different (P &gt; 0.05) among treatments (averaging 5.94, 0.990, and -12.9 kPa, respectively). The NH treatment accumulated the greatest (P &lt; 0.05) Fo and cook values during the cook cycle compared to all other treatments. The NH and GG treatments were more (P &lt; 0.05) red and yellow than KCGG, LBGGG, and XGGG. Gums and gelling carbohydrates influenced the rate of heat penetration of the foods, likely due to the differences in batter consistency, and affected product color and physical characteristics.

Abstract This paper seeks to explain the structural effect on selected properties of freeze-dried gels with different compositions and aeration times. Herein, sugars and citric acid were added to gels with low-methoxyl pectin, mixtures of xanthan gum and locust bean gum, as well as xanthan gum and guar gum, in order to obtain a strawberry model. Strawberry pulp was also added to hydrocolloids to develop an innovative strawberry product. All samples were aerated for 3 and 7 min, and freeze-dried. Composition changes were found to modify the structure of the examined samples and properties. Freeze-dried gels with low-methoxyl pectin seemed to reflect the best approach towards obtaining an innovative strawberry product with a tailored structure, as they had the best water absorbent capacity, and the most attractive and delicate structure. Samples with a mixture of hydrocolloids were more compact. Aeration time did not significantly affect the examined parameters, while the addition of sugar and citric acid increased them. The strawberry pulp experiment confirmed the strawberry model (with low-methoxyl pectin gels, and sugar and citric acid), which had the finest structure and the best rehydration properties.

Purpose Celiac disease patients cannot consume gluten-containing diets; thus, gluten-free products should be offered to meet the nutritional needs of these patients. The purpose of this study was to produce gluten-free tarhana for celiac disease patients using corn flour instead of wheat flour and investigate some physicochemical properties of tarhana. Hydrocolloids were used to compensate for technological deficiencies caused by the absence of gluten. Design/methodology/approach Hydrocolloids including guar gum, xanthan gum and locust bean gum were added at concentrations of 0.5% and 1.0% to the corn flour. The substituted corn flour samples were used to produce tarhana powder. Findings The pH and acidity measurements were carried out in 0th, 24th and 48th h of fermentation, and for all samples, the pH gradually decreased during fermentation, whereas the acidity increased. According to the color measurements (L, a and b values), it was observed that there was no significant difference (p = 0.588) between the gums in terms of L values in tarhana dough samples. Water retention capacity values of control, guar gum 1%, xanthan gum 1% and locust bean gum 1% were found to be 1.1, 1.1, 0.7 and 1.2 mL/g, respectively. The viscosity measurements were carried out at three different temperatures (30°C, 45°C and 60°C), and the viscosity values were found to decrease significantly (p = 0.000) with the increase in temperature for all the samples studied. The highest viscosity values were obtained by 1.0% xanthan gum (4,333 mPa s) and 0.5% locust bean gum (3,575 mPa s) added tarhana samples for 3 rpm at 30°C. Xanthan gum addition showed the lowest foam capacity values (0.04 mL/mL) among the samples. The samples with guar gum, xanthan gum and locust bean gum are recommended with regard to consistency and foam stability in the production of tarhana. Originality/value This study confirms that the use of gums in tarhana, a gluten-free system, is beneficial for the technological aspect. The unfavorable properties that can be seen because of the absence of gluten in corn flour tarhana can be compensated with the use of hydrocolloids, and tarhana can be recommended to celiac disease patients.
