总膳食纤维快速整合试剂盒 K-RINTDF Rapid Integrated Total Dietary Fiber Assay Kit
总膳食纤维快速整合试剂盒
英文名:Rapid Integrated Total Dietary Fiber Assay Kit
货号:K-RINTDF
规格:100 assays per kit
市场价: 4039元

应用范围:
-
This test kit is suitable for the measurement and analysis of Total Dietary Fiber as per Codex Alimentarius definition, updated to be more consistent with in vivo conditions in the human small intestine, i.e. a 4 h incubation time. Under these conditions more accurate measurement of resistant starch is obtained, including phosphate cross-liked starch (RS4). Use of higher enzyme concentrations ensures that resistant maltodextrins produced from non-resistant starch under the incubation conditions of the Integrated Total Dietary Fiber procedure (AOAC Methods 2009.01 and 2011.25 are no longer produced.
In this rapid, improved method, the incubation time with PAA + AMG is reduced to 4 h and the levels of both PAA and AMG are increased to ensure that resistant starch levels obtained with a set of control samples are consistent with ileostomy data. Under these conditions, the DF values obtained for most samples are the same as those obtained with AOAC Methods 2009.01 and 2011.25.
The dietary fiber fractions that are measured with this method are:
1. High Molecular Weight Dietary Fiber (HMWDF) including Insoluble Dietary Fiber (IDF) and Low Molecular Weight Soluble Dietary Fiber (SDFS; soluble dietary fiber which is soluble in the presence of 78% aqueous ethanol), or
2. Insoluble dietary fiber (IDF), Higher Molecular Weight Soluble Dietary Fiber (SDFP; water soluble dietary fiber that precipitates in the presence of 78% aqueous ethanol) and SDFS.
The enzymes used in this method are high purity and effectively devoid of contaminating enzymes active on other dietary fiber components such as β-glucan, pectin and arabinoxylan. They are supplied as freeze-dried powders; allowing the use of glycerol as an internal standard.For the determination of Total Dietary Fiber in cereal products, foodstuffs, feeds and other materials.
Principle:
(Pancreatic α-amylase + amyloglucosidase)
(1) Non-resistant starch + H2O → D-glucose(protease)
(2) Protein + H2O → peptides(3) IDF (including resistant starch) and alcohol precipitated
soluble DF (SDFP) determined gravimetrically(4) Alcohol soluble DF (SDFS) determined by HPLC
(5) Ash and residual protein determined on DF residues
and subtractedKit size: 100 assays
Method: Hydrolysis/removal of non-dietary
fibre components
Total assay time: ~ 3 h work (over 1-2 days)
Detection limit: 0.5-100% of sample weight
Application examples:
Food ingredients, food products and other materials
* See McCleary, B. V., Sloane, N & Draga, A. (2015). Determination of total dietary fibre and available carbohydrates: a rapid integrated procedure that simulates in vivo digestion. Starch /Starke, 66, 1-24.Advantages
- More rapid measurement – incubation time with PAA + AMG reduced to 4 h in comparison with AOAC 2009.01 (increased levels of enzyme employed)
- DF values for most samples are very similar to those obtained with AOAC Method 2009.01
- Rapid Integrated Total Dietary Fiber method removes all of the limitations that have been identified with AOAC Method 2009.01*
- All reagents stable for > 2 years after preparation
- The method is consistent with the CODEX Alimentarius definition of dietary fiber
- Mega-Calc™ software tool is available from our website for hassle-free raw dataprocessing
- Very competitive price (cost per test)
FAQ解答
Q1. How should I prepare the required 78% ethanol solution?
A volume reduction occurs on mixing water with 95% ethanol (or IMS). 1 L of 78% ethanol is prepared by adding 821 mL 95% ethanol (or IMS) to 207 mL H2O.
If using a 1 L volumetric flask, this is best accomplished by placing 821 mL 95% ethanol (or IMS) into the volumetric flask. Dilute to volume with deionised water. Mix well. Check the level and if necessary add more deionised water to bring it back up to the 1 L mark.

特克拉德灵长类饮食是固定的配方饮食,以提供适当的营养平衡所需的新世界和旧世界灵长类动物的所有品种和年龄。饮食是为了提供统一的实验和生产结果而制定的。
植物、牛奶和鱼类蛋白质来源的结合提供了必需氨基酸的适当数量和平衡,以维持研究灵长类在其整个生命周期和研究功能中的物理状况。
高质量的脂肪来源提供了生长、维持和繁殖所需的必需脂肪酸的平衡。这些脂肪来源也提供了一种高可消化的能源。
特克拉德灵长类饮食强化维生素和矿物质,包括维生素D 3,以适当的骨发育和维生素C预防坏血病和贫血。稳定维生素C(L-抗坏血酸-2-聚磷酸)用于延长保质期.饮食是营养完整和平衡的,因此额外的饮食补充剂是不必要的。
特克拉德灵长类食物被挤压出来,以帮助分解淀粉,提高消化率和适口性。喂食高可消化的膨化食物会产生坚固的大便,这有助于减少清洗时间。折叠所有标签没有一个确定的点,人们能够预测什么时候一个特定的饮食会变质或变得缺乏一个或多个营养。六个月保质期的共同准则是以北美长期的实践为基础的。在欧洲和亚洲,当地做法和监管监督方面的差异导致特克拉德标准天然成分饮食被例行使用到9个月,有时甚至在生产后12个月。这种实践经验,随着时间的推移,再加上文献支持和维生素测试,让我们相信,这些饮食继续支持动物的健康和研究的完整性,至少在9个月后生产。如果你不确定当地的政策,请向你的机构寻求指导。
建议的储存条件:- 凉爽和干燥;在华氏70度或以下,湿度最好在50%以下,但高达65%是可以接受的。
- 清洁无害虫
- 在原始包装中或容器中,防止连续暴露于光线下,并将空气暴露在最小范围内。
一般来说,非人类灵长类动物将消耗相当于其体重百分之四的食物,但是有许多因素可以影响日常消费,包括物种、生命阶段、住房和环境条件。少量的水果、蔬菜或坚果可以作为环境丰富的食物。清洁的淡水应始终可用。Teklad primate diets are fixed-formula diets formulated to provide the proper balance of nutrients required by new-world and old-world primates of all breeds and ages. Diets are formulated to provide uniform experimental and production results.
A combination of plant, milk and fish protein sources supplies the proper amounts and balance of essential amino acids necessary to maintain the physical condition of research primates throughout their life cycle and research function.
High-quality fat sources provide the balance of essential fatty acids required for growth, maintenance, and reproduction. These sources of fat also provide a highly digestible source of energy.
Teklad primate diets are fortified with vitamin and minerals including vitamin D3 for proper bone development and vitamin C for prevention of scurvy and anemia. Stabilized vitamin C (L-ascorbyl-2-polyphosphate) is used to extend the shelf life. Diets are nutritionally complete and balanced making additional dietary supplements unnecessary.
Teklad primate Diets are extruded to help break down starches, improving digestibility and palatability. Feeding highly digestible extruded diets results in firm stools, which helps reduce cleaning time.Products Teklad primate diets Non-autoclavable form Teklad global 20% protein primate diet 2050 Teklad global 25% protein primate diet 2055 Teklad hi-fiber primate diet 7195 Teklad 15% monkey diet 8714 Teklad 15/10 hi-fiber monkey diet 8788 Teklad new world primate diet 8794 Not all products are stocked locally; extended lead time and additional fees may apply.
Many diets are available in certified format designated by a “C” following the product code. When diets are certified a representative sample is tested for a panel of contaminants. If not stocked as certified, certification can be made available upon request. Minimum order size and additional charges may apply.COLLAPSE ALL TABSThere is no definitive point where one is able to predict when a specific diet will spoil or become deficient in one or more nutrients. The common guideline of a six month shelf life is based on longstanding practice in North America. In Europe and Asia, differences in local practices and regulatory oversight have led to Teklad standard natural ingredient diets being routinely used out to nine months and sometimes 12 months post-manufacture. This practical experience, along with literature support and vitamin testing over time, gives us confidence that these diets continue to support animal health and study integrity out to at least nine months post-manufacture. Please refer to your institution for guidance if you are unsure of local policies.
Recommended storage conditions:- Cool and dry; at or below 70 degrees fahrenheit with humidity ideally below 50%, but up to 65% is acceptable
- Clean and free of pests
- In original packaging or in a container that prevents continuous exposure to light and minimal exposure to air
In general, nonhuman primates will consume an amount of diet equal to four percent of their body weight but there are many factors that can affect daily consumption including species, life-stage, housing, and environmental conditions. Small amounts of fruits, vegetables, or nuts may be fed as environmental enrichment. Clean fresh water should always be available.康宁corning 3581 DISPOSABLE SPINNER FLASK,3L,WITH VENT CAP,S,IND,1/4 1个/包
