Introduction
My research area of interest is to understand the metabolic network in plant cells, finding the efficient pathways of active molecules biogenesis, Identifying the molecular mechanism of corresponding genes and withdrawing the general pressure of unnecessary metabolism in plant cell culture to produce the valuable phytopharmaceuticals in vitro and more efficiently. I worked with Rhodiola rosea but in general, the novel plants are my favorites.

Dear researchers,
I have prepared sodium alginate beads by dropwise addition of 1.5% alginate solution to 1M CaCl2. The outcome was an acceptable bead with satisfying size and hardiness. My aim is to put this alginate beads into a product such as honey. But when I mix the beads with honey, they start to be dissolved and getting smaller. That is due to the high sugar content of the honey which makes an osmotic current.
Does anybody have ideas or experience in this context? I also mixed sodium alginate with honey in a ratio of 50:50 but it did not prevent the observed phenomenon. Any protocol of co-polymerization or double coating bi maltodextrin or hydroxyl ethyl cellulose is also of my interest.
Many thanks in advance,
Iman
I’m using a titration experiment to determine the degree of esterification (DE) in pectin solutions. I want to compare the effect of different enzymes activity of pectin by comparing the DE after enzymatic treatment. The initial pH of 2%pectin is around 2.6 which is not an optimum pH for the enzymes; therefore I had to add NAOH to adjust the pH to 5.5. Now my question is can I start the titration with NAOH from this 5.5 to 8 and then to 12 (recording the volume of used NAOH)and adding the HCL to lower the pH to 8 again! Or I have to lower back the pH to 2.6 after enzymatic treatment and then starting the titration method as my Protocol said.
I’d be thankful if someone with chemistry knowledge help me to grasp the proses.
