Following pre-treatment, the samples were dried in a tray dryer at 50°C. The full-cream milk paneer was found to have the highest moisture content compared to other paneer varieties due to the homogenization process. The overall dimensional properties of OD-treated paneer, including average length, width, thickness, geometric mean diameter, surface area, and volume, ranged from 0.0174 to 0.0196 m, 0.0164 to 0.0186 m, 0.004 to 0.0054 m, 0.0108 to 0.0121 m, 0.34 × 10⁻³ to 0.464 × 10⁻³ m², and 11.71 × 10⁻⁷ to 17.991 × 10⁻⁷ m³, respectively.

Subsequently, an optimal combination of the test parameters (i.e., 66°C, 17.5 mm/s, 6.7 g sample) has been proposed. These aimed to minimize variability and ensure the reproducibility of the results in the stretchiness of the observed cheese. The key stretch descriptors' significance to describe the stretchiness of cheese, namely peak force, force and work at a distance of 40 mm, and breaking distance has also been indicated. With the proposed method, changes in the stretch properties of Mozzarella during storage at 4°C were able to be monitored. An initial decrease was observed up to day 7, followed by a slight increase by day 25, suggesting changes in the cheese protein network. The method was then used to compare the properties of 15 dairy-based cheeses and 6 vegan Mozzarella-style cheese alternatives. The peak force and filament strength (i.e., force at a distance of 40 mm) were used to cluster various cheeses showing distinct stretch profiles. Mozzarella cheeses generally showed lower resistance to filament formation compared to other dairy-based cheeses, while vegan cheeses exhibited minimal to no filament formation and lower meltability. By comparing and clustering the stretchiness properties of dairy cheeses and their vegan alternatives, the present method can be used to guide researchers and product developers on better profiling the stretch properties of target cheese and subsequently producing (new) products with a more desirable stretch profile.</p>","PeriodicalId":17175,"journal":{"name":"Journal of texture studies","volume":"56 2","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jtxs.70012","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143533407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given that disliking drives non-consumption, here we explore how particle size, concentration, and salivary flow rate may affect liking in a fiber-fortified model beverage. Beverages made with 2 particle sizes of wheat brans (D₉₀ = 976 μm and 209 μm) in 3 concentrations (5%, 7.5%, 10% w/v) were compared to a control beverage (no fiber added) and 2 commercial fiber-fortified beverages (Detoxifiber, ARG Cellulose) at 7.5% w/v concentration. Under controlled laboratory conditions, 90 adults (30% men, 58% women; age range = 18–79 years) rated beverage liking and the intensity of particles remaining in the mouth/throat. Individuals were divided into low and high salivary flow groups; rinsing time and rinse water weight were also recorded following consumption. As expected, higher particle concentration reduced liking, but particle size showed no main effect on liking. Surprisingly, no significant difference was found between salivary flow groups on liking and remaining particles perception. However, we saw a significant negative correlation (<i>r</i> = −0.93) between liking and particles remaining ratings.

The results indicated that high-gluten flour had a higher gluten content but inferior gluten quality, as evidenced by lower stability time, gluten index, and farinograph quality number compared to low and medium gluten flours. However, high-gluten flour contributed to the production of noodles with greater hardness, tensile strength, and tensile displacement, while also reducing cooking loss at elevated alkali levels. Increased salt addition was found to decrease cooking loss, whereas the addition of alkali had the opposite effect. To achieve a high relative content of mainly characteristic volatile compound (hexanal), the alkali addition should exceed 0.4%, with optimal performance observed at 0.8%. Moreover, increasing the water content during mixing significantly reduced cooking loss but adversely affected the textural properties of the noodles. Noodles prepared using vacuum mixing exhibited a hardness that was 6.67% greater than those prepared by normal mixing. Extending the dough resting time to 30 min further reduced cooking loss by 2.02%.

However, the parameters defining firmness vary across the literatures. To optimize the parameter(s) for characterizing the firmness of peaches and nectarines, we evaluated 31 parameters derived from force–displacement curves using fruit with various maturity levels and storage durations. Our findings affirmed that the conventional Magness–Taylor measurement effectively delineated firmness changes associated with varying maturity levels, while its ability to capture firmness changes due to storage duration was constrained. On the contrary, parameters extracted from the steady phase (P2), which depict flesh properties after penetrating to a specified depth, exhibited strong performance across diverse maturity stages and storage durations. As effective firmness characterization parameters should differentiate various sample groups based on both maturity and storage duration criteria—pivotal factors influencing softening, the P2-derived parameters are thus deemed more appropriate for firmness characterization. Given the stability of the steady phase (P2) within the force–displacement curve and the high correlation among the P2-derived parameters, it is more recommended to use the end force value of P2, corresponding to the force value at 10 mm depth to represent the firmness of peaches and nectarines.</p>\u0000 </div>","PeriodicalId":17175,"journal":{"name":"Journal of texture studies","volume":"56 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143007480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
