Kimura, Y., Sumiyoshi, M., Tamaki, T., 2013. Arch. The following section describes the method of producing noodles containing sweet potato granules. Chlorogenic acids do not dissolve in low concentration ethanol solutions, whereas some impurities are desorbed in high ethanol concentrations. The adsorption capacity rose as the original TPC increased if the original TPC was less than 2.0 mg CAE/mL. 0111 011300 WhatsApp us! (2007) found that commercial grade fractionated pectin powder could strongly promote prostate cancer cell apoptosis in male hormone-sensitive and male hormone-insensitive people, and produced thermal-modified pectin used in fractionated pectin powder production, which had similar effects on prostate cancer cell apoptosis. 1.4 EXTRACTION OF PECTIN The extraction of pectin generally includes the following four parts: The pretreatment of the raw materials (to remove the small molecular weight carbohydrates and pigments), pectin hydrolysis and extraction, pectin purification, and pectin drying. Separation of chlorogenic acid from honeysuckle crude extracts by macroporous resins. Liu et al. When the oil-phase volume fraction was less than 10%, the emulsified particles pectin adsorption ratio increased slightly, but the difference was not significant. J. Biochem. Chlorogenic acid protects MSCs against oxidative stress by altering FOXO family genes and activating intrinsic pathway. Anthocyanin color behavior and stability during storage: effect of intermolecular copigmentation. If the water quantity is too small, the pulp is not easy to be formed, and the pulp quality is not uniform; if the water amount is too large, the potato pulp is too thin, which is not beneficial to fermentation. Hung Med. Zhuang, H., Zhang, J.H., 2003. Internal factors, such as the contents of galacturonic acid and neutral sugars, the degree of esterification, the degree of acetylation, and molecular weight (Yapo and Koffi, 2008; ODonoghue and Somerfield, 2008), and also various external factors, such as the ash content and ionic strength in a pectin solution, also affect the gelation of pectin. Serum transaminases, such as ALT and AST, are essential catalysts in human metabolic processes. J. Agric. When the Ca21 concentration was greater than 2.0 mM, the Ca21 concentration increased (Fig. Agric. 6.34). Chemother. Different pH values had different influences on the color change associated with the anthocyanins. Puspo, E.G., Takuya, H., Yusuke, O., et al., 2010. Fang, Y.J., Chiu, C.H., Chang, Y.Y., et al., 2011. Microwave-assisted extraction of chlorogenic acids from green coffee beans. PDF | On Feb 21, 2018, V.D. After sweet potatoes are soaked in calcium solutions at different concentrations, the produced granules contain different free starch contents, with a variance of 6%. Crit. When the injection volume was 5 BV, the TPC of the effluent solution was 0.2 mg CAE/mL, which was a tenth of the initial concentration. The resin was defined as being at adsorption equilibrium when the TPC of the eluted solution was a tenth of the initial sample solution and the total volume of the eluted solution was at the dynamic handling capacity of the resin. The invention relates to a food processing technology, concretely a processing method of a sweet potato stem leaf can, and belongs to the technical field of deep-processing of agricultural products. Assays for hydrophilic and lipophilic antioxidant capacity (oxygen radical absorbance capacity (ORACFL)) of plasma and other biological and food samples. 6.8. After homogenizing at 24,000 rpm for 1 min, the properties of the characteristic indices, including emulsion particle size, viscosity, emulsifying activity index (EAI), emulsion stability index (ESI), and the absorption of emulsified particles to pectin, of sweet potato pectin emulsions prepared under different conditions were explored. The microwaves heating mechanism is different from conventional heating, because it can penetrate the material and the extraction solvent, resulting in a uniformly heated system. Taira, J., Taira, K., Ohmine, W., et al., 2013. Zhang, B., Yang, R., Zhao, Y., et al., 2008. Caffeic acid is a small phenolic acid, thus its hydrolyzation does not induce significant changes in the TPCs of sample solutions. 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. Compared with the control, P , 0.05, Compared with the model, #P , 0.05, ##P , 0.01. J. Clin. Get in touch with us now. Tseng, K.C., Chang, H.M., Swi-Bea, W.J., 2006.

Thus, the healthcare market is greatly interested in anthocyanins. Alpha-glucosidase inhibitory and antioxidant activities of vietnamese edible plants and their relationships with polyphenol contents. Li, J.L. SECTION 3: BIOLOGICAL ACTIVITIES OF SWEET POTATO PECTIN We mentioned in the first section that pectin could inhibit the growth and metastasis of cancer cells and promote cancer cell apoptosis; however, high molecular weights or poor water solubility levels may hinder or limit the anticancer effects. The reputed roles of sweet potato leaves, as indicated by their nicknames, such as anticancer vegetables, space food, and longevity greens, are directly related to their abundant chlorogenic acids contents (Islam et al., 2003; Ishida et al., 2000). SECTION 5: THE APPLICATIONS OF CHLOROGENIC ACIDS FROM SWEET POTATOES 5.1 FOOD INDUSTRY Chlorogenic acids are a new type of high-efficiency phenolic antioxidant that can fully or partially replace the commonly used synthetic antioxidants in some foods. The results showed that the emulsions in the high oil phase volume fraction were more stable than the emulsions in the low oil phase volume fraction. The mechanisms that thermal-modified citrus pectin uses to induce the apoptosis of prostate cancer cells are not known, but exposing thermal-modified pectin to an alkali treatment significantly decreased the prostate cancer cells apoptosis-inducing activity, which indicates that the alkali-sensitive structures of thermal-modified pectin are required to induce the apoptosis of prostate cancer cells. Gao, M., Huang, W., Liu, C.Z., 2007. The post-fermentation can make the potato pulp have mellow flavor. These changes may be due to the anthocyanins being relatively stable under lower pH conditions (pH # 4). J. Agric. Gryglewski, R.J., Palmer, R.M.J., Moncada, S., 1986. 0.05). For example, the acylation of anthocyanins stabilizes the pigment mainly because of the enhanced interaction. This is the basis of the Aqueous two-phase extraction (ATPE) method (Planas et al., 1996). SECTION 2: TECHNOLOGIES AND KEY POINTS IN MANUFACTURING SWEET POTATO GRANULES 2.1 MANUFACTURING TECHNOLOGIES After years of painstaking research, our laboratory proposed an entire high-quality sweet potato granule manufacturing process involving several important technologies. However, because methanol is highly volatile and has a certain toxicity, it should not be used as a natural pigment extraction agent but is Sweet Potato Anthocyanins 287 mainly used for anthocyanin analyses and structural identification. Technol. A high viscosity can prevent the flocculation of emulsified particles (Mishra et al., 2001), and maintain the stability of the emulsion.
