Even after heating for 4 h at 100 C, the anthocyanin preservation rate was still greater than 80%. However, with further increases in the TPC, more impurities were adsorbed on the AB8 resin, resulting in competition for active sites between the chlorogenic acids and the impurities, which led to a slight drop in the adsorption capacity. Song (2009) invented a purple sweet potato wine, which has antiaging, anticancer, and antiatherosclerosis effects, and can improve immunity. 57, 62856291. Although thin-layer chromatography is simple, the separation difficulties and the vulnerability to interference by impurities result in it being not often used in the qualitative and quantitative analyses of chlorogenic acids. There are broad market prospects for this technology.

The results for Y1 and Y2 are shown in Tables 6.6 and 6.7, respectively. 3.3.2.2 Proper Amount of Sweet Potato Granules for Noodle Production If excessive sweet potato granules are added, the gluten content of noodles is insufficient, making the noodles less elastic, easy-to-break, and less resistant to cooking. With the increase in treatment time, the inhibitory effects of thermal-modified pectin improved greatly and the best effect occurred at 24 h. With the increase in treatment time, the inhibitory effects of pH-modified pectin increased. Food. FURTHER READING Arslan, N., Kar, F., 1998. Antiviral Res. In addition, the ion-exchange resin, which can remove all kinds of metal ions and does not react with high molecular weight pectin, has been used to purify the pectin. 1.2.1 Homogalacturonan HGA is an essentially linear polymer containing B100200 (1,4)linked -galacturonic acids (Willats et al., 2001), in which parts of the carboxyl groups could be methyl esterified.

Dongowski, G., Lorenz, A., 2004. Alkaline peeling treats materials with an alkaline solution at a certain concentration, and then washes them to remove their skins (Liu et al., 1999). The reaction rate constant increased and the half-life decreased as the temperature increased, and the thermal degradation laws were in line with first-order kinetics, whether the solvent was deionized water, or 10%, 20%, or 50% ethanol, and the fit coefficients at 75 and 100 C were larger than those at 4 and 25 C, indicating anthocyanin degradation under high temperature conditions was better fit to the first-order reaction kinetics than degradation under low temperature. Lastly, based on the regression equation, the galacturonic acid content of the diluted solution was calculated, and then, the total content of galacturonic acid in solution was obtained by multiplying the diluted factor. Several chemical methods have been used for the hydrolysis of neutral sugar side chains, which vary among 190 Sweet Potato Processing Technology themselves because of the differences in the acid types, the acid concentrations, and the time and temperature of hydrolysis. Therefore, we used hydrochloric acid to extract pectin from sweet potato pulp. Rajesh, M.G., Latha, M.S., 2004. 42, 6574. The viscosities of the other three materials increased with increasing salt concentrations, and the viscosities of the sweet potato residue, sweet potato powder, and soybean dietary fiber were not different at the same NaCl concentrations.

For wound healing of raw sweet potatoes, the following parameters are used: Temperature: 30 C; humidity: 92%; duration: 47 days (Van Oirschot et al., 2006). At a pectin concentration of less than 2.0%, the emulsion particle diameter increased significantly (P , 0.05) after being maintained at room temperature for 1 and 7 days, when compared with the fresh emulsion, and when the pectin concentration was greater than 2.0%, the resting time had no significant effect on the emulsion particle size. The solution was diluted 100 times with distilled water before the test. (2007) used an Sweet Potato Pectin 193 ion-exchange resin to purify pectin, and the main performance index and the pectin yield were superior to those achieved by traditional methods. The reaction rate constant k and the activation energy, Ea were determined graphically from a plot of ln(C/C0) versus time and ln k versus 1/T, respectively. 4.3) in which parts of the galacturonic acid resides may be O-acetylated at C-3 or C-2, but at present, no studies showed that they could be methyl esterified.

In contrast, in relatively high pH solutions, chlorogenic acids may exist as ions due to the ionization reaction, which are more difficult to adsorb. Acetaldehyde is an alcohol metabolite that can combine with GST, resulting in changes in membrane permeability and fluidity, and thus, the structure and function of the cells being damaged.
