Hull-less pumpkin seed press-cake, a by-product of the pumpkin oil pressing process, was used to formulate a fat-based spread which resembled commercial peanut butter; both in the appearance and in texture. In this study, response surface methodology was used to investigate the effects of a commercial stabilizer and cold-pressed hemp oil added to the pumpkin seed press-cake, on the texture of the formulations using instrumental texture profile analysis. The responses were significantly affected by both variables tested in a central composite, two factorial experimental design on five levels. Strong and firm spreads, without visible oil separation were formed and had an appearance and texture comparable to commercial peanut butter. In terms of the primary food texture attributes such as hardness, cohesiveness and adhesiveness, determined by the instrumental texture analysis, the optimum combination of variables with 1-1.2% of added stabilizer and 20- 40% of added hemp oil (in the oil phase) produced desirable spreads.

A peloid’s liquid phase can be mineral, sea or salt-lake water. This study examines the interactions among three materials, two special clays (bentonite and sepiolite) and one common clay, and three chemically different mineral-medicinal waters. In all clay–water mixtures, the hardness and adhesiveness decreased with the amount of water in the mixture. For a given hardness or adhesiveness, sepiolite retained more water than the other clays, especially in the presence of sulphate-rich mineral-medicinal water (73%). In contrast, the common clay retained the least amount of water (26%), and the bentonite samples returned an intermediate value for the amount of retained water (52–53%). These differences had a strong influence on the thermal behaviour of the mixtures and, hence, should be taken into account for their use in thermotherapy applications. There were no significant differences in the instrumental texture of the clay pastes according to the predominant anion in the mineral-medicinal waters.

Texture profile analysis of any food product shows correlation with sensory and overall consumer acceptability of the developed milk products. Instrumental texture profile analysis was conducted on low fat milk nuggets prepared with 2% fat milk coagulum and skim milk coagulum and extended with optimum levels of barnyard millet flour and finger millet flour. The texture profile analysis results showed higher values for hardness, springiness, cohesiveness, gumminess and chewiness for the milk nuggets prepared with 2% fat milk coagulum as compared to the nuggets prepared with skim milk coagulum.

Models capable of predicting product quality of shelled sunflower seed caramel snack have been developed using response surface methodology. The textural profile analysis was conducted on the snacks using a texture analyzer. The quality attributes measured were hardness, cohesiveness, springiness, chewiness, and resilience as a function of sugar and sunflower kernels content. The sugar and shelled seed proportions affect the textural characteristics of the product significantly (p<0.05). The values of hardness, cohesiveness, springiness, chewiness, and resilience varied from 2.048 to 42.030 N, 1.002 to 5.003, 1.138 to 1.69, 2.773 to 228.146N, and 0.301 to 0.779, respectively. The highest values of hardness and chewiness were attained for the product with 70:30 sugar and shelled sunflower seed proportion respectively. Similarly the highest values of cohesiveness, springiness and resilience were observed in 50 : 30, 50 : 40, and 50 : 50 proportions respectively. The lowest values of hardness and chewiness were observed in 50 : 50 (sugar: shelled sunflower seed) proportion respectively. Similarly the lowest values of cohesiveness were observed in 70: 50 whereas the lowest values of springiness and resilience were observed in 70 : 30 proportions respectively. Hardness, cohesiveness, and chewiness trended to increase whereas springiness and resilience decreased with increase in sugar proportion.

Abstract Background: Increasing viscosity can reduce the risk of aspiration into the airway, but conversely, very thick solid food may require greater strength and effort. We assumed that semi-solid foods with similar viscosities will behave differently in the oropharynx and there might exist the possibility that properties other than viscosity may have clinical relevance. This study aimed to find out the texture of semi-solid foods that affects the effort of pharyngeal swallow in the elderly. Methods: Nine kinds of semi-solid foods not requiring mastication were selected for texture profile analysis (TPA), and included whipped cream, mayonnaise, soft tofu, mango pudding, boiled mashed pumpkin, boiled mashed potatoes, boiled mashed sweet potatoes, red bean paste, and peanut butter. Hardness, adhesiveness and cohesiveness of each food were measured three times by using the rheometer. A blinded sensory test using a 9-point hedonic scale was also conducted in eighteen elderly people to investigate how much effort was required to swallow food, and how much of the food remained in the pharynx after swallowing. The correlation between texture and sensory outcome was statistically analyzed.Results: Foods that belonged to the same viscosity category showed different texture values, and the participants also rated different scores respectively. Only adhesiveness among three properties was significantly correlated with the sensory test. (r= 0.882, p=0.002 for difficult to swallow, r=0.879, p=0.002 for sense of residue).Conclusions: Adhesiveness was the most important property of the semi-solid foods, requiring most efforts in pharyngeal swallow in the elderly. If we select and provide food having low adhesiveness value in the same viscosity category, there might be the possibility to make it easier to swallow in older adults.

Introduction. Date press cake is a waste product of date juice making that can lead to potentially serious environmental problems if discarded in large amounts in open areas. Therefore, it needs to be utilized. Our study aimed to investigate the possibilities of using date press cake powder to formulate innovative ready-to-eat products – vegan biscuits and vegan protein bars. Study objects and methods. The food products under study were subjected to a palatability test, a nutritional value evaluation, a texture profile analysis, and a scanning electron microscopy, as well as a microbiological assay performed during 8 months of storage. Results and discussion. The palatability test showed that the biscuits supplemented with 10% date press cake had the best acceptable preference, compared to control, 5 and 15% date press cake samples. Our innovative vegan protein bar scored highest in overall acceptability, flavor, taste, texture, and willingness to buy, compared to the commercial vegan protein bar. Overall, our study showed that both of our products were safe to consume within 8 months. Additionally, our innovative protein bar and fortified biscuits had high proportions of the recommended dietary allowances for most nutrients for adolescents and athletes, especially for vegetarians. Conclusion. Date press cake can be successfully used as a food ingredient to produce new formulations of vegan protein bars. Additionally, it can be used as an alternative ingredient to improve the nutritional quality of vegan biscuits.
