【摘要】:目的:異麥芽酮糖在運動飲料的開發(fā)研制方面具有廣闊的前景,可依據(jù)異麥芽酮糖低血糖指數(shù)(GI)的特性,與其它糖類配比,研制不同GI的運動飲料,特別是較低GI的運動飲料。由于異麥芽酮糖原料的來源不同,其GI值可能存在一定的差異。因此,需要對擬作為運動飲料原料的異麥芽酮糖的GI值進行測定。本研究擬比較不同血糖儀對異麥芽酮糖飲料GI值測定的影響,以及不同含糖量和不同體積的異麥芽酮糖飲料對GI值的影響。 方法:選取10名健康成年女性受試者志愿,按照《食物GI測定國際標(biāo)準(zhǔn)》(ISO26642:2010)進行測試。采集指尖血,分別采用YSI-1500血糖儀和羅氏卓越血糖儀,測定口服50g-250ml(20g/100ml)、50g-500ml(10g/100ml)、25g-250ml(10g/100ml)和25g-500ml(5g/100ml)的異麥芽酮糖飲料的GI值。 結(jié)果:共采集718個血樣(包括預(yù)實驗),YSI血糖儀測定50g-250ml,50g-500ml,,25g-250ml和25g-500ml四種不同CHO、不同體積(濃度)條件下,異麥芽酮糖的GI值分別為32.18±3.74,31.00±3.55,37.40±7.18,36.76±6.08;羅氏血糖儀測定50g-250ml,50g-500ml,25g-250ml和25g-500ml四種不同CHO、不同體積(濃度)條件下,異麥芽酮糖的GI值分別為33.75±5.00,29.50±3.52,46.30±10.81,37.50±5.50。 結(jié)論:(1)按照ISO26642:2010要求,50g-250ml濃度條件下,兩種血糖儀均適用于異麥芽酮糖的GI值的測定。(2)50g-250ml濃度條件下,測得的異麥芽酮糖的GI值更準(zhǔn)確。25g-500ml濃度條件下,測得的異麥芽酮糖的GI值和國際標(biāo)準(zhǔn)濃度比較并無明顯差異。25g-250ml濃度條件下,測得的異麥芽酮糖的GI值和這兩種濃度比較起來有顯著性差異。
[Abstract]:Objective: isomaltose has a broad prospect in the development of sports drinks. According to the characteristics of isomaltose hypoglycemia index (GI) and the ratio of other sugars, different GI sports drinks, especially sports drinks with lower GI, can be developed. Due to the different sources of isomaltosugar, there may be some differences in GI value. Therefore, the GI value of isomaltoose to be used as raw material for sports beverage needs to be determined. The purpose of this study was to compare the effects of different blood sugar instruments on the determination of GI value of isomaltose drinks and the effects of different sugar contents and volumes of isomaltose drinks on GI values. Methods: ten healthy adult female volunteers were selected and tested according to the International Standard for the determination of Food GI (ISO 26642: 2010). The blood samples from fingertips were collected, and the GI values of isomaltoketoose drinks with 50g-250ml (20g/100ml) 50g-500ml (10g/100ml) 25g-250ml (10g/100ml) and 25g-500ml (5g/100ml) were determined by YSI-1500 and Roche's superior glycometer, respectively. Results: a total of 718 blood samples (including pre-test) were collected. The GI values of isomaltose were 32.18 鹵3.74 鹵3.537.00 鹵3.537.40 鹵7.187.40 鹵36.76 鹵6.08 under different volume (concentration) conditions. The GI value of isomaltose was 33.75 鹵5.00 鹵29.50 鹵3.52 鹵46.30 鹵10.81 鹵37.50 鹵5.50 under the different volume (concentration) conditions of 50g-250ml, 50g-500ml, 25g-250ml and 25g-500ml, respectively. Conclusion: (1) according to the requirement of ISO 26642: 2010, the two kinds of blood saccharometers are suitable for the determination of GI value of isomaltocarbohydrate. (2) under the condition of 50g-250ml concentration, the GI value of isomaltocarbohydrate is more accurate at the concentration of .25g-500ml. There was no significant difference between the GI value of the measured isomaltosugar and the international standard concentration. At the concentration of 25g-250ml, the GI value of the measured isomaltocarbohydrate was significantly different from that of the two concentrations.
