How does the increase in temperature affect the bulk density of whole tamarind seeds?
5 answers
The increase in temperature affects the bulk density of whole tamarind seeds. As per the studies, higher temperatures during drying lead to a decrease in bulk density of tamarind seeds. Specifically, the bulk density decreased from 873.9 to 851.4 kg/m3 as the moisture content increased within the range of 7.55 - 10.47% (d.b). This decrease in bulk density with increasing temperature can be attributed to the changes in the physical properties of the seeds caused by the drying process. Therefore, it can be concluded that elevated temperatures result in a reduction in the bulk density of whole tamarind seeds, impacting their overall physical characteristics.

Why does Cholesterol coating decreases nanostructured lipid carriers size?
5 answers
Cholesterol coating decreases the size of nanostructured lipid carriers (NLCs) due to its impact on particle formation and stability. Research indicates that the addition of cholesterol to NLCs results in the formation of smaller particles compared to NLCs without cholesterol, as seen in the study by Riangjanapatee et al.. However, while cholesterol enables the creation of smaller particles, it also reduces the stability of the drug within the NLCs, affecting the overall size and integrity of the carriers. Therefore, to maintain the chemical stability of the drug in NLCs, it is recommended to avoid cholesterol in the formulation and store the NLCs appropriately at lower temperatures, as highlighted in the same study.
