The 2-hydroxy-3-butoxypropyl guar gum
was synthesized with guar gum
as material, using n-butyl glycidyl ether as the hydrophobic reagent, sodium hydroxide as catalyst and isopropanol as solvent.
(G4129) was procured from Sigma-Aldrich (USA) and commercially available thermophilic starter culture (Streptococcus thermophilus and Lactobacillus delbrueckii subsp.
It can be seen from Table 1 and Figure 2 that with the increase of sand ratio, the settling velocity of sand in thickening water and guar gum
Emulsifier (MDG and DATEM) and gums (guar gum
and CMC) were added according to the experimental design shown in Table 1.
Effects of guar gum
and xanthan gum on pasting and rheological properties of native and modified potato starch.
In terms of materials, it is evident that the higher moisture content corresponds to samples coated with guar gum
(> 3%) which is also related to its ability to bind and immobilize water, a product of its high viscosity.
Tamarind gum, xanthan gum, and guar gum
