Native sago starch was phosphorylated with 5% sodium tripolyphosphate (STPP) or crosslinked with 4% phosphorous oxychloride (POCl3) at pH 8 to 11. The modified starches were characterized for degree of substitution (DS), pasting properties, crystallinity and molecular structure. The results indicated that DS of phosphorylated sago starch prepared at pH 9 was 0.008, which was the highest value a...

An analysis of the household economy of a sweetpotato-producing county in Sichuan Province of China shows that sweetpotato is currently under-utilized in an inefficient sweetpotato-pig feed system. Meanwhile, poverty drives many young men and women to seek employment opportunities in major coastal cities far from home. This paper reviews the contributions of sweetpotato, pigraising, and migrati...

Potato starch offers several unique properties essential for nutrition, and numerous non-nutritional applications. First of all, it is the sole native starch of anionic character. For that reason, potato starch combines, for instance, with proteins forming various complexes considered as potential biodegradable plastics. Potato starch is, practically, the sole starch variety containing a consid...

Chemically modified starches (CMS) are RS4-type resistant starch, which shows a reduced availability, as well as high-amylose corn starch (HACS, RS2 type), compared with the corresponding unmodified starch. Previous studies have shown that RS4 increases fecal excretion of bile acids and reduces zinc and iron absorption in rats. The aim of this study was to investigate the effects of dietary RS4...

Compared with floury or high-moisture corns, dry corn with a greater percentage of vitreous endosperm has been demonstrated to be negatively related to starch digestibility and milk yield of lactating dairy cows. Starch granules in corn are encapsulated by hydrophobic prolamin proteins that are innately insoluble in the rumen environment. Corn prolamin proteins are named zein, and laboratory me...

High red meat (HRM) intake is associated with increased colorectal cancer risk, while resistant starch is probably protective. Resistant starch fermentation produces butyrate, which can alter microRNA (miRNA) levels in colorectal cancer cells in vitro; effects of red meat and resistant starch on miRNA expression in vivo were unknown. This study examined whether a HRM diet altered miRNA expressi...

The objective of this work was to improve aqueous solubility of poorly water soluble drugs by a modified porous starch as solid dispersion carrier. The yield of the porous starch was found to be 80%. The flow property of the prepared porous starch was found to be good, with good compressibility index. The particle size of the prepared porous starch were found to be in the range of 53–130μ. Ther...

Starch structure strongly influences starch physicochemical properties, determining the end uses of starch in various applications. To produce starches with novel structure and exploit the mechanism of starch granule formation, an (engineered) 4, 6-α-glucanotransferase (GTFB) from Lactobacillus reuteri 121 was introduced into two potato genetic backgrounds: amylose-containing line Kardal and am...

Gas production (GP) and starch degradation (STAD) from starchy feedstuffs were measured simultaneously by in-vitro incubation in buffered rumen fluid after 0, 4, 6, 8, 12, 16 and 24 h incubation to explore the possibility to estimate STAD via GP technique for starchy feedstuffs. The results showed the ranking in the initial degree of starch degradation and gas production. Potato starch and maiz...
