  • Effects of resistant starch as a functional substitute on the quality of Yukwa were determined. Replacement ratios of resistant starch were 2, 4, and 6% of glutinous rice flour. Regarding pasting properties of Yukwa dough replaced with resistant starch, initial pasting temperature significantly increased and peak viscosity significantly decreased with increasing resistant starch. The moisture contents of bandegi and Yukwa base replaced with resistant starch were higher than that of the control. The expansion ratio of Yukwa base replaced with resistant starch significantly decreased with increasing resistant starch, and there were no significant differences in the oil absorption ratio. Lightness (L) of Yukwa base replaced with resistant starch increased significantly with increasing resistant starch. Appearance of Yukwa base replaced with resistant starch showed a shortened length and increased width with increasing resistant starch, and cross-section showed an oval shape, fine air cell distribution, and increased outer layer thickness. Hardness and peak number increased significantly with increasing resistant starch. The overall acceptability of Yukwa base replaced with 6% resistant starch was the highest among the samples, but the result was not significant. The above results show that resistant starch substitution in Yukwa improved the texture and further could improve health functionality due to its dietary fiber content. Resistant starch was appropriate as a 6% replacement for glutinous rice flour in Yukwa.

  • The objective of this study was to compare the textural properties and sensory evaluation of Injulmi, a traditional Korean waxy rice cake, added with 10, 20 and 30% of RS3-type resistant starch. RS3-type resistant starch was prepared from nonwaxy rice(Odaebyeo) starch by autoclaving-cooling cycle. The RS yield of RS3-type resistant starch was 9.10%. By increasing the addition level of RS3-type resistant starch, the hardness and adhesiveness of Injulmi increased as measured by using a rheometer. Hunter color L and a values of Injulmi added with RS3-type resistant starch were increased, but b value was decreased. In case of sensory evaluation, the hardness of Injulmi added with RS3-type resistant starch was higher than that of non-added Injulmi. The overall duality of Injulmi added with RS3-type resistant starch by sensory evaluation was negatively correlated with the hardness measured by rheometer(p<.0.05).

  • Effects of RS4 type resistant corn starch on the quality characteristics of cookies were investigated by physicochemical, instrumental and sensory evaluation. The resistant starch was made by cross-linking of corn starch as following; corn starch slurry was annealed at pH 2.0 and $50^{\circ}C$ for 2 h followed by the cross-linking reaction. The cross-linking reaction was performed at $50^{\circ}C$ for 12 h in the presence of 1.2%/st.ds NaOH, 10%/st.ds sodium sulfate and 10%/st.ds of sodium trimetaphosphate (STMP)/sodium tripolyphosphate (STPP) mixture. Dietary fiber content of the resistant starch was estimated to be 73.8% by the AOAC method. For quality characteristics, dough pH decreased with the increase of the resistant starch content and spread factor decreased a little at 20% of the resistant starch. The moisture content and L value of cookies increased with the increase of the resistant starch content. However, the hardness and fracturability decreased with the increase of the resistant starch content. In the sensory evaluation, no significant differences were observed between the two cookies with or without the resistant starch. The results of this study suggest that the RS4 type resistant corn starch can be a good ingredient to increase dietary fiber content in cookies without changes of their qualities.

  • In order to observe the effects of resistant starches on human glycemic response, nine female university students were investigated using cellulose (CED), resistant starch 3 (RS3D) and resistant starch 4 (RS4D) diets. Each woman's blood sugar and insulin, triacylglycerol and free fatty in plasma concentration were measured at fasting state, then 15, 30, 45, 60, 75, 90 and 120 minute after each test diet feeding. Glycemic indices of the Cellulose diet (CED: 57.9 $\pm3.00$), the Resistant starch 3 diet (RS3D: 52.6 $\pm7.9$) and the Resistant starch 4 diet (RS4D: 52.9 $\pm10.2$) were similar to each other, but they were significantly lower in comparison with those of white wheat bread diet (WWBD: 100). Insulinemic indices of the CED (49.8 $\pm8.2$), RS3D (50.0 $\pm7.3$) and RS4D (72.4 $\pm7.7$) were significantly lower in comparison with the white wheat bread diet (WWBD: 100), but among the dietary fiber diets, the insulinemic index of RS4D was significantly higher than the CED and the RS3D. Plasma triacylglycerol contents of the CED, RS3D and RS4D including WWBD showed gradual increase in tendency after lowering in early stage of each test diet feeding, but not significantly different in each dietary fiber added diet. Plasma free fatty acid contents of the CED, RS3D and RS4D including WWBD showed gradual decrease in tendency after each test diet feeding, but not significantly different by each dietary fiber added diet. In above results, we speculate that resistant starch 3 controls rapid elevation of blood sugar by delaying intestinal digestion and absorption of cellulose, but the result appears to be different from RS4 in comparison. Thus, RS3 intakes may contribute to the diet therapy of diabetic humans, but more studies on RS4 is needed in the future. (Korean J Community Nutrition 9(4): 528∼535, 2004)

  • Purpose: The consumption of noodles has increased domestically. However, noodles with high carbohydrate content can cause an increase in blood glucose compared with other foods. Therefore, in this study, Naengmyeon with high resistant starch was prepared for decreasing blood glucose by the addition of 0.5% citric acid (CN), 1% guar gum (GN) or 0.5% citric acid and 1% guar gum (CGN), and then it was incubated in a refrigerator for 3 days, and stored in a freezer for 1 month. Methods: The quality characteristics of these Naengmyeon noodles was evaluated based on total starch, resistant starch, water absorption, cooking loss, turbidity, in vitro starch hydrolysis, and in vivo glucose response. Results: There was no significant difference in the total starch, cooking loss, and turbidity. The resistant starch of GN (1.70%) and CGN (1.84%) was significantly increased when compared with that in Naengmyeon with no additives (N) and CN. In terms of water absorption, CN (86.01%) was the lowest in samples, followed by GN (92.17%), N (94.20%), and CGN (99.16%). CGN with high resistant starch was the lowest in in vitro starch hydrolysis in samples. However, it had no effect on the in vivo glucose response. In vitro starch hydrolysis exhibited a significant positive correlation (r=0.533; p<0.01) with in vivo glucose response. Conclusion: Therefore, future studies are needed to establish the standard for resistant starch contents in processed carbohydrate foods for delaying the increase in blood glucose. If this standard is established, it might help to develop processed foods for diabetic patients.

  • As a result of resistant starch yield depending on heating temperature, moisture content, storage temperature and heating-cooling cycle with RSM (response surface methodology), high amylose corn starch (46%) was appeared higher than normal corn starch in the yield (22%). At the high amylose corn starch, optimum conditions for resistant starch formation were 6 times of heating-cooling cycle, 108$^{\circ}C$ heating temperature and 67% moisture content at the 2$0^{\circ}C$ storage temperature, which resulted in 25% yield with these experiment conditions. Affecting factor for the resistant starch formation was arranged according to heating -cooling cycle, moisture content, heating temperature and storage temperature. Raw corn starch granule was destructive and appeared a porous reticular structure by the resistant starch formation. Color became dark and increased yellowness by caramelization during heating processing. Heating-cooling processing was the result of decreased hardness, cohesiveness, springiness and gumminess.

  • Generally, dietary fibre (DF) includes lignin, non-starch polysaccharides (NSP) and resistant starch (RS). In monogastric species, low levels of dietary fibre in the diet are associated with various diseases and high levels reduce nutrient digestibilities. In this study, the effects of different types and levels of NSP (soluble: $\beta$-glucan, insoluble cellulose) and resistant starch on mucin secretion and endogenous nitrogen and amino acid losses in pigs were investigated. A total of 25 five-week-old weaner pigs (9.5 kg${\pm}$1.5 kg), were randomly allocated to each of five experimental diets. Different levels of purified barley $\beta$-glucan (BG) extract (5 or 10% of $Glucagel^{(R)}$ $\beta$-glucan, providing 4 or 8% of BG in the diet), and resistant starch (RS) (8.3 or 16.6% of Hi-$Maize^{TM}$, providing 5 or 10% RS in the diet) were substituted for wheat starch in a purified diet in which enzymatically-hydrolysed casein was the sole source of protein. The diets were fed for 21 days. No statistically significant difference between treatments (p>0.05) was observed for growth performance and organs weights. No difference in ileal starch digestibility was observed between pigs on the cellulose or $\beta$-glucan diets. However, as the level of resistant starch in the diet increased the ileal starch digestibility decreased (p<0.05). The inclusion of resistant starch in the diet (5 or 10%) did not increase mucin production when compared with the cellulose-only diet. However, as the level of beta-glucan in the diet increased, both crude mucin in the digesta dry matter and per kg dry matter intake increased (p<0.05). Pigs fed the diet containing 8% of beta-glucan had higher endogenous loss flow than those fed the diets including 5 or 10% of resistant starch or 4% of $\beta$-glucan. In conclusion, dietary inclusion of resistant starch increased the level of starch reaching the large intestine without any effect on mucin secretion, or endogenous nitrogen or amino acid losses content in the small intestine. The addition of $\beta$-glucan to a diet containing cellulose increases both mucin secretion and endogenous amino acid and nitrogen losses in the small intestine.

  • Physicochemical and sensory characteristics of the jam with various levels of resistant starch were investigated in this study. Water content of RS20(20% resistant starch) jam had significantly the highest value of all(p<0.05) and RS5 showed significantly the highest value in sweetness. The value of pH were increased with increasing levels of the resistant starch in jam preparation. The Hunter L and a values of RS20 had the highest value among all groups. The hardness of jam was increased as the contents of the resistant starch was increased. Results of sensory characteristics of RS20 showed significantly higher values in strawberry aroma, sweetness, after taste and chalky and showed significantly lower values in strawberry flavor, spreadability, redness and glossiness than those in the other sample groups at p<0.05. Strawberry flavor, spreadability, redness and glossiness of RS5 had the largest values at the significant level(p<0.05).

  • In order to observe the effects of resistant starches on the physio-nutrition in women, nine female university students were investigated using cellulose (CED), resistant starch 3 (RS3D) and resistant starch 4 (RS4D) diets. Each woman's daily intake and excretions of energy, protein and lipid were mesured together with the apparent digestibility and the amounts of total cholesterol and HDL-cholesterol were measured. The results obtained from this researh are as follows. The daily energy intake were significantly higher in the RS4D (Resistant starch 4 diet) compared with the CED(Cellulose) and the RS3D (Resistant starch 3 diet). The metabolic energy in those periods with RS added to their diets were significantly higher whereas the metabolic energy in the period CED was significantly low. The daily protein intake was significantly higher in the RS4D compared with the CED and the RS3D. The apparent digestibility of protein was significantly higher in the RS4D compared with the CED and the RS3D. The daily lipid intake was significantly higher in the CED compared with the RS3D and the RS4D. The apparent digestibility of lipid was not significant in that period. The concentration of total cholesterol, HDL-cholesterol, % of HDL-cholesterol and atherogenic index (A.I.) were not significant in those period. As the above results indicate, while RS3 appear to have similar effect on energy consumption rate, apparent protein digestibility and content of cholesterol in plasma, compared with the CED, but energy consumption rate and apparent digestibility of protein are significantly higher in the RS4D compared with the CED. Thus, it appears that cellulose and RS 3 share similar effects on physio-nutrition in human, while RS4 does not have the similar effects. (Korean J Nutrition 35(9) : 932∼942, 2002)

  • We have investigated the intestinal functions and hypolipidemic effects of resistant starch (RS) in rats. Experimental groups were CON (cooked starch 45% + RS 7%), RSIO (cooked starch 35% +RS 10%), RS20 (cooked starch 25%+RS20%), and RS30 (cooked starch 15%+RS 30%). The weight gains during experimental period were slightly decreased by intake of resistant starch and the weights of epididymal fat pad were lower in resistant starch intake groups than in CON, although the difference was not significant. In intestinal functions, water contents of fecal, transit time and colon cell proliferation were affected by resistant starch. Plasma total lipid and triglyceride concentrations were significantly decreased, dose-dependently, by resistant starch intake. Conclusively, it is important to intake resistant starch in order to decrease plasma lipids and to improve intestinal functions.
