Data from: Effect of storage time on physical properties of sonocrystallized all-purpose shortening

The purpose of this study was to determine the effect of high-intensity ultrasound (HIU) on the physical properties of an all-purpose shortening and to evaluate how these properties changed during storage (48 hr; 4, 12, and 24 weeks) at 5 °C and 25 °C. Samples were crystallized at 30 °C for 60 min with and without the application of HIU (20 kHz; 3.2 mm-diameter tip, 168 μm amplitude, 10 s). After crystallization, physical properties, such as hardness, elasticity, melting behavior, and solid fat content (SFC), were measured. These properties were also measured during storage. The effect of HIU was significant in changing the SFC, hardness, G' and G", melting enthalpy, and microstructure of the samples. After 60 min of crystallization, the sonicated samples had higher values of SFC, hardness, elasticity, and melting enthalpy than the ones obtained without sonication (P < 0.05). Changes in these physical properties were associated with the microstructure of the samples since sonication generated smaller, more uniformly sized crystals as well as increased the number of crystals. No differences were observed in the G' of the sonicated samples stored at 25 °C as a function of the storage period. The G' of the non-sonicated samples increased until 12 weeks of storage and was maintained up to 24 weeks, suggesting that sonication speed up the formation of a stable crystalline network. Samples stored at 5 °C showed higher value in hardness, G' and G", and SFC than the ones stored at 25 °C. Resources in this dataset:Resource Title: README.

本研究旨在探究高强度超声波（HIU）对通用短化剂物理性质的影响，并评估这些性质在储存过程中（48小时；4、12、24周）在5°C和25°C条件下的变化情况。实验样品在30°C下结晶60分钟，分别进行超声波处理（20 kHz；直径3.2毫米的探头，振幅168微米，10秒）和无超声波处理。结晶后，对样品的物理性质，如硬度、弹性、熔化行为和固体脂肪含量（SFC）进行了测量。这些性质在储存期间也进行了测量。高强度超声波对SFC、硬度、G'和G''、熔化焓和样品微观结构的变化具有显著影响。结晶60分钟后，超声波处理样品的SFC、硬度、弹性和熔化焓值高于未经超声波处理的样品（P < 0.05）。这些物理性质的变化与样品的微观结构有关，因为超声波处理生成了更小、尺寸更均匀的晶体，并增加了晶体的数量。25°C储存的超声波处理样品的G'值在储存周期内没有观察到差异。未经超声波处理的样品的G'值在储存至12周时增加，并维持至24周，这表明超声波加速了稳定结晶网络的形成。在5°C储存的样品在硬度、G'和G''以及SFC方面的值高于在25°C储存的样品。本数据集包含的资源包括：资源标题：README。文件名：README.txt。资源描述：该文件包含数据集的README（包括数据字典）。资源标题：APD数据。文件名：APS_Data.zip。资源描述：压缩目录中包含6个文件夹。文件夹图1、2和3、图4、5和表3、图6和表4、图7、表1和表2包含论文中报告的实验数据。图1、2和3包含18个BMP文件，图4、5和表3包含181个CSV表格，图6和表4包含121个CSV表格，图7包含169个CSV表格，表1包含1个CSV表格，表2包含1个CSV表格。总共有473个CSV表格和18个BMP文件。
