  • This study was conducted to analyze the contents in the dietary fiber and amino acid compositions of 23 vegetables and 6 fruits and to identify the current contents. We generated data on the contents of total, insoluble and soluble dietary fiber (TDF, IDF and SDF), respectively. The TDF and IDF contents were lowest (0.56 g/100 g and 0.44 g/100 g) in wild garlic and highest (5.87 g/100 g and 5.66 g/100 g) in perilla leaves. A total of 18 kinds of amino acids were found in most samples. Essential and non-essential amino acid contents ranged from 53.16-2107.54 mg/100 g and 191.66-2892.28 mg/100 g, respectively. The highest essential and non-essential amino acid content was hot pepper leaves followed by perilla leaves and aralia. They had higher contents of both TDF and amino acids. The results of the study can serve as a fundamental source of information in DF and amino acids for diet planning.

  • To observe the food quality of Baik-kimchi which is known as a watery Chinese cabbage pickles without fish sauce and red pepper paste, the changes of dietary fibers and pectic substances during fermentation at 5$^{\circ}C$ and $25^{\circ}C$ were studied. Baik-kimchi fermented at $25^{\circ}C$ showed a greater changes in pH and acidity than those of 5$^{\circ}C$ during storage. Ripened Baik-kimchi products fermented at 5$^{\circ}C$ could be prepared on 9~12 days of fermentation, and those had a pH range from 4.25 to 4.40 and acidity of 0.34~0.53. But in the case of $25^{\circ}C$ fermentation, Baik-kimchi ripened for 3 days showed a pH of 4.02 and acidity of 0.54. The pH and acidity of the Baik-kimchi juice changed more rapidly than those of the Baik-kimchi solid regardless of fermentation temperatures. The content of soluble dietary fiber(SDF) was ranged from 3.06 to 4.87% at 5$^{\circ}C$ and a wide variation in SDF was observed in the sample fermented at $25^{\circ}C$(4.15~11.22%). Insoluble dietary fiber(IDF) were increased from 21.66% to 28.42% in solid of Baik-kimchi during fermentation at 5$^{\circ}C$ and ranged from 21.37% to 24.65% for sample fermented at $25^{\circ}C$. A notable amount of pectin had been dissolved in juice of Baik-kimchi till the best ripening time and showed the level of 223.2mg/100ml at 5$^{\circ}C$ on the day of 9 and 207.3mg/100ml at $25^{\circ}C$ on the day of 2. In contrast, the contents of pectin in solid Baik-kimchi decreased, whereas contents of sodium hexametaphosphate soluble pectin(HXSP) and HCl soluble pectin(HClSP) increased with fermentation period.

  • This study aimed to evaluate the effect of dietary fiber supplementation with snack type on functional constipation. We conducted a double blind case-control study with 3 groups; placebo, low dose group (LD: insoluble fiber 7 g/d + soluble fiber 1.2 g/d) and high dose group (HD: insoluble fiber 14 g/d + soluble fiber 2.4 g/d) , which were randomly assigned out of subjects with functional constipation, defined by modified Rome II criteria. We measured anthropometric parameters and evaluated the bowel movement frequency, stool type, straining, sense of complete evacuation, abdominal discomfort/pain, abdominal inflation, relief and colon transit time before, during the supplementation. Both LD and HD groups had significant improvement in straining, sense of complete evacuation and satisfactory relief compared with placebo group (p < 0.05). When subdivide by baseline colon transit time (less than 24 hrs/ 24 hrs or more and less than 72 hrs / 72 hrs or more), only HD group had significantly improvement; colon transit time recovered near by 24 hrs in subjects of 'less than 24 hrs' (from $7.57{\pm}1.40$ hrs to $25.2{\pm}3.91$ hrs, p < 0.01) and reduced in those of '24hr or more and less than 72 hr' (from $47.0{\pm}3.36$ hrs to $31.3{\pm}4.31$ hrs, p < 0.01) and '72 hr or more' (from $106.7{\pm}10.7$ hrs to $85.0{\pm}13.1$ hrs, P < 0.05) subjects. Particularly, positive effect of fiber supplementation on straining and sense of complete evacuation in test groups seemed to be greater in subjects of '24 hrs or less' and '24 hrs or more and less' than 72 hrs' than those of '72 hrs or more'. In conclusion, subjects with functional constipation, particularly those having colon transit time less than 72 hrs can significantly improve, at least in part, symptom related to constipation by fiber supplementation of snack type without serious side effects.

  • Objective: A study was conducted to determine the chemical composition of barley and co-products from barley, corn, and wheat produced in South-East Asia or Australia, and to test the hypothesis that production area or production methods can impact the chemical composition of wheat co-products. Methods: Samples included seven barley grains, two malt barley rootlets, one corn gluten feed, one corn gluten meal, one corn bran, eight wheat brans, one wheat mill mix, and four wheat pollards. All samples were analyzed for dry matter, gross energy, nitrogen, amino acids (AA), acid hydrolyzed ether extract, ash, minerals, starch, and insoluble dietary fiber and soluble dietary fiber. Malt barley rootlets and wheat co-products were also analyzed for sugars. Results: Chemical composition of barley, malt barley rootlets, and corn co-products were in general similar across countries. Wheat pollard had greater (p<0.05) concentrations of tryptophan, magnesium, and potassium compared with wheat bran, whereas wheat bran had greater (p<0.05) concentration of copper than wheat pollard. There were no differences in chemical composition between wheat bran produced in Australia and wheat bran produced in Thailand. Conclusion: Intact barley contains more starch, but fewer AA, than grain co-products. There were only few differences in the composition of wheat bran and wheat pollard, indicating that the two ingredients are similar, but with different names. However, corn gluten meal contains more protein and less fiber than corn bran.

  • This study was conducted to investigate the physicochemical properties of the ethanol extracts and soluble dietary fiber from Cassia tora L. seed. The proximate composition of Cassia tora, soluble solid contents, color intensity and contents of emodin and rhein of Cassia tora extract, molecular mass distribution, sugar contents and viscosity of soluble fiber from Cassia tora were analyzed. Cassia tora contains 12.6% of moisture, 5.2% of ash, 13.4% of crude protein, 7.2% of crude fat, 8.8% of insoluble fiber and 48.3% of soluble fiber. The effects of extract condition on soluble solid contents, color intensity and contents of emodin and rhein of Cassia tora extract were investigated. The soluble solid contents were higher in 70% or 50% ethanol extracts than those in 100% ethanol extracts and showed highest value in grind sample extracts. In Hunter's color value, 100% ethanol extracts and whole Cassia tora sample extracts were higher in L and b value, but on the contrary, were lower in a value, than those of the other. The highest emodin and rhein contents were observed in 70% and 50% ethanol extracts, respectively, and showed higher value in room temperature extracts than in heating extracts. The molecular mass of soluble fiber from Cassia tora seed was estimated by gel filtration chromatography. Most soluble fiber(80%) exhibited a molecular mass range of between 50~2000 kDa. The major sugars of soluble fiber from Cassia tora seed were identified as xylose, mannose and galactose. The apparent viscosity of 0.5% soluble fiber from Cassia tora seed was 33 mPas showing a higher value than pectin or xanthan gum.

  • This study was conducted to estimate the general components, minerals, and dietary fiber contents of Synurus deltoides. S. deltoides contained 81.1% moisture content, and the proportions of crude fat, crude protein, crude ash, and crude fiber were 0.3%, 4.2%, 2.6%, and 3.5%, respectively. Potassium (3,249.1 mg) was the most abundant component among the minerals in S. deltoides. In addition, S. deltoides contained many other minerals, e.g. calcium (854.8 mg), phosphorus (60.3 mg), magnesium (344.7 mg), sodium (57.3 mg), zinc (1.7 mg), iron (30.9 mg), copper (0.8 mg), and manganese (5.8 mg). Almost all of the mineral contents of S. deltoides were higher than those of Aster scaber and Ligularia fischeri, except for zinc, copper, and manganese. Total dietary fiber (TDF), insoluble dietary fiber (IDF), and soluble dietary fiber (SDF) contents of S. deltoides were 42.6 g, 37.9 g, and 4.7 g, respectively, and these were also higher than those of A. scaber and L. fischeri used in this study. These results suggest that S. deltoides may be a valuable nutrient source.

  • This study investigated the effects of insoluble dietary fibers from pine (Pinus radiata D. Don) inner bark powder (PIBP) on loperamide constipation in rats. Male Sprague-Dawley rats were administered PIBP in their diets at concentrations of 5% and 10% for 4 weeks. Rats were divided in to four groups, normal diet group (Cont), a normal diet and loperamide group (Lop), 5% PIBP experimental diet and loperamide group (Lop+PIBP 5%), and 10% PIBP experimental diet and loperamide group (Lop+PIBP 10%). Constipation was induced by oral administration of loperamide (2 mg/kg, twice per day) for the last three days of the experiment. Food intake, body weight, properties of feces, gastrointestinal transit time, and serum lipid profiles were measured. When compared with the normal diet and loperamide group (Lop), there were increases in fecal pellet number (p<0.05), wet weight (p<0.001), and water content (p<0.001). Positive results were derived from relevant indicators to improve constipation. In addition, the number of fecal pellets in the colon was not significant, and decreased as PIBP content increased. PIBP had a concentration-dependent effect on reduction of total cholesterol, LDL-cholesterol, and triglycerides and elevation of HDL-cholesterol. These results indicate that PIBP may effectively prevent constipation.

  • The fibrous material fraction as a by-product from the commercial aloe vera gel processing was obtained and freeze dried. The physicochemical characteristics such as the proximate composition, crystalline/surface structures and several physical functionalities including the water holding capacity (WHC), swelling capacity (SW), oil holding capacity (OHC), emulsion/foam properties and viscosity properties of this powdered sample (100 mesh) were investigated and analyzed by comparison with commercial $\alpha$-cellulose as a reference sample. The total dietary fiber content of powdered sample was very high as much as 87.5%, and the insoluble dietary and soluble dietary fiber content ratios were 77.6 and 22.4%, respectively. The FT-IR spectrum of powdered sample showed a typical polysaccharide property and exhibited a x-ray diffraction pattern for cellulose III and IV like structure. SW (8.24${\pm}$0.15 mL/g), WHC(6.40${\pm}$0.19 g water/g solid) and OHC(10.32${\pm}$0.29 g oil/g solid) of freeze dried aloe cellulose were about 3.3, 1.4 and 2 times higher than those of commercial $\alpha$-cellulose, respectively. Aloe cellulose (~2%, w/v) alone had no foam capacity while improved the foam stability of protein solution (1% albumin+0.5% $CaCl_{2}$) by factor of 300%. Emulsion capacity of 2%(w/v) aloe cellulose was about 70% level of 0.5%(w/v) xanthan gum, but its emulsion stability was about 1.2 times higher than that of xanthan gum. Also, aloe cellulose containing CMC (carboxyl methyl cellulose) of 0.3%(w/v) showed a very good dispersity. Aloe cellulose dispersion of above 1%(w/v) exhibited higher pseudoplasticity and concentration dependence than those of $\alpha$-cellulose dispersion, indicating the viscosity properties for new potential usage such as an excellent thickening agent.
