For the measurement of amylose/amylopectin ratio and content in cereal starches and flours. Based on a Con A precipitation procedure. Content:100 assays per kit

Colourimetric method for the determination of Amylose and
Amylopectin in cereals, food and feed

Principle:
(Con A)
(1) Soluble starch (amylose + amylopectin) →
amylose + amylopectin-Con A
(soluble) (precipitate)

(α-amylase + amyloglucosidase)
(2) Amylose (in solution) + H2O → D-glucose

(glucose oxidase)
(3) D-Glucose + H2O + O2 → D-gluconate + H2O2

(peroxidase)
(4) H2O2 + p-hydroxybenzoic acid + 4-aminoantipyrine →
quinoneimine + H2O

(α-amylase + amyloglucosidase)
(5) Total starch (in solution) + H2O → D-glucose

Kit size: 100 assays
Method: Spectrophotometric at 510 nm
Total assay time: ~ 120 min
Detection limit: Amylose 5-95% of total starch content
Application examples:
Cereal starches, flours, pure starches and foods
Method recognition: Novel method

Advantages

  • Very cost effective (cost per test)
  • All reagents stable for > 12 months after preparation
  • Only enzymatic kit available
  • Accurate and reliable amylose / amylopectin ratio determination
  • Simple format
  • Standard included

Q1. Should the pH of the sample be adjusted even for samples in acidic media?

The pH of the assay solution after the sample is added should be the same as that of the assay buffer that is supplied with the kit.
Low sample volumes (e.g. 0.1 mL) are not likely to affect the pH of the assay solution and therefore may not require pH adjustment.
Samples above 0.1 mL are more likely to affect the pH of the assay solution and therefore the pH of these samples should be adjusted as described in the data booklet, prior to addition to the assay.

Q2. There is an issue with the performance of the kit; the results are not as expected.

If you suspect that the Megazyme test kit is not performing as expected such that expected results are not obtained please do the following:

  1. Ensure that you have tested the standard sample that is supplied with the Megazyme test kit.
  2. Send the results of the kit standard, blank samples and the results obtained for your sample,  in the relevant MegaCalc spreadsheet (if available) to Megazyme (cs@megazyme.com). Where available the relevant MegaCalc spreadsheet can be downloaded from where the product appears on the Megazyme website.
  3. State the kit lot number being used (this is found on the outside of the kit box).
  4. State which assay format was used (refer to the relevant page in the kit booklet if necessary).
  5. State exact details of any modifications to the standard procedure that is provided by Megazyme.
  6. State the sample type and describe the sample preparation steps if applicable.

Q3. With your amylose/amylopectin kit can you calculate the amylose content from the Con A supernatant absorbance, without performing the total starch section if you have recorded the weight of the sample?

Amylose is always reported as a percentage of the starch, not as a percentage of the sample weight. The method should be followed as described.

Q4. Can K-AMYL also be used for total starch determination?

We do not recommend K-AMYL for starch measurement. The aim with this method is to get a representative sample of the starch to get the amylose content. For accurate starch determination, we recommend using K-TSTA.

Q5. Do you provide any information in your Amylose/Amylopectin kit for the separation of the two starch fractions?

We think that the only effective method to separate amylose and amylopectin is by gel filtration.

Q6. We are analysing amylose using your kit K-AMYL. Do you have any recommendations regarding sample grinding? We have used a Retsch laboratory mill with a 0.5 mm screen. The particle size may be important for starch extraction.

Mill with Retsch 0.5 mm screen.

Q7. I am interested in your Amylose/Amylopectin Assay Kit. Is this assay suitable for potato starch?

The method should be fine for amylose/amylopectin in potato starch.

Q8. Could you please give us details about the reproducibility of the Amylose/Amylopectin kit?

Reproducibility +/- 2 to 4% of the value.

Q9. How sensitive is your Amylose/Amylopectin kit – can it differentiate between 50/50 and a 55/45 ratio?

Yes, there should be no problem in distinguishing samples with these differences in amylose content.

Q10. I have a question regarding your amylose/amylopectin assay kit. The solution (supernatant) is not always clear after centrifuging (A5) and after mixing with Con A solvent (A7) – depending on the sample. Is this a problem or is this OK?

Solution not always clear A5 – this is ok.  Solution not always clear A7 – this is ok as well.

Q11. What kind of flour is the reference starch sample in your Amylose/Amylopectin kit from (potato, rice, wheat)?

The starch control is high amylose maize starch.

Q12. In your Amylose/Amylopectin Kit can you please tell me what modifications for steps A2 – A7 can be used for problem samples which do not appear to dissolve fully in DMSO (e.g. rice flours, potato starch)?

We suggest that you make the following changes:
1. A2 – use 2 mL DMSO
2. A4 – use total of 12 mL Ethanol (4 + 8– need longer tubes)
3. A6 – use 2 mL of DMSO
4. A7 – use 4 mL of Con A solvent.
Of these, the changes in A6 and A7 are probably the most important. 

Q13. What is the difference between your Amylose/Amylopectin kit and the Total Starch Kit? I need to separate amylose from amylopectin in maize plants and quantify each fraction and wonder which kit would be most suitable.

The Amylose/Amylopectin kit employs Con A to selectively precipitate the amylopectin.

Q14. In the ConA precipitation step, after the hour incubation, is the centrifugation speed or temperature more important, or are they equally important?

Speed of centrifugation is the most important parameter.  We use the microfuge at room temperature.

Q15. When we measure the Amylose/Amylopectin content of Sagopalm & rice starch (powder form), white precipitate is remaining. Adding DMSO after the precipitation by adding ethanol, white precipitate is remaining. Can you let us know a counter measure?

The white precipitate is most probably protein, and this will cause no real problems. However, an alternative is as follows:
Page 6:
Step 2: Dissolve in 2 mL DMSO. Centrifuge at high speed (could use a micro-centrifuge – 14,000 rpm, but bench centrifuge – 3,000 rpm, may be OK) and recover the supernatant.  Treat this as follows:
Step 4: Add 4 mL ethanol, then 8 mL of ethanol.
Step 6: Use 2 mL of DMSO.
Step 7: Use 4 mL of Con A solvent and then make up to 25 mL as per method.

Q16. I have trouble with Steps A4 and A6 of your Amylose/Amylopectin Kit, i.e. distributing or dissolving the sample in DMSO without forming gelatinous lumps (starch) or grimy material that sticks to the sides of the tube (flour). How can I avoid this?

Rice starch should dissolve completely, but the solution may not be "crystal clear".  In fact, it generally isn’t.  With rice flour, the solution will be quite turbid due to materials other than starch, which will not dissolve.  You can also increase the amount of DMSO used in the test.  We have now introduced this modification into the method.

三菱化学大孔吸附树脂

三菱化学大孔吸附树脂

日本三菱化学填料面世已有 40 多年历史,其中 DIAION 和 SEPABEADS 品牌大孔吸附树脂享誉全球。它以吸附量高,颗粒均匀,机械强度好,不易破碎,残留物少,预处理方便而闻名世界,主要包括 HP , SP 系列(以聚苯乙烯-二乙烯基苯为基体)和 HP2MG 系列(以甲基丙烯酸酯为基体)。

1、芳香族系:DIAION HP20,HP21

因为具有比较大的孔径,适于大分子的吸附。解吸性良好,吸附物的溶离较容易,所以适用范围很广泛,可应用于各种工业领域。

2、芳香族系:SEPABEADS SP825L,SP850,SP700

与HP20相比,大幅度提高了比表面积,并且孔径的大小比HP20更小且均一,因此能把较小的分子大量吸附,吸附物的解析也容易。

3、芳香族系:SEPABEADS SP70

符合美国FDA标准(CFR§173.65)的芳香族系大孔吸附树脂,具有中等的细孔径。

4、芳香族系衍生型:SEPABEADS SP207

SP207是在芳香族系的骨架上结合了溴,从而强化了疏水吸附力。另外,其比重是其他大孔吸附树脂的1.2倍,所以适于由下向上流动的反向处理。

5、甲基丙烯系:DIAION HP2MGL

与芳香族系不同,HP2MGL采用聚甲基丙烯酸酯为原料,中等极性,可吸附极性较高的物质。

应用范围:

聚苯乙烯合成吸附树脂:吸附含有π电子的化合物,如含有苯环和共轭双键的化合物。

甲基丙烯酸酯类吸附树脂:不含芳香环,属中等极性的吸附树脂,吸附含有羧基、酯基、氨基、酰胺基等与氢可结合的官能团的化合物。由于该聚合物有较强的亲水性,所以适合脱盐和吸附较强极性的化合物。

沸石膜

沸石是一种具有规则孔道结构的晶体,而且耐高温、抗化学和生物腐蚀、机械强度高,所以在分离、催化等方面具有很好的发展前景。而将沸石制备成厚度为微米级的薄膜可以实现分子的分离,即根据分子大小的不同实现分离。对于沸点接近或具有共沸点的混合物的分离,传统的精馏、萃取等技术能耗较大,且操作复杂, 而沸石由于孔道大小与大多数分子的大小接近,可以利用分子筛分的原理分离上述的混合物体系。日本三菱化学推出了三种形式的沸石膜,提高了耐水性和耐酸性,扩大了应用范围,延长了沸石膜的使用寿命。

沸石膜

特点1.适用的含水率范围比较广

沸石膜一般为NaA型(与ZX0相同沸石膜),一般的NaA型(ZX0)无法应用在含水率15%以上脱水,三菱化学的膜含水率大于15%时也可以脱水。

特点2.高通量

ZXO与竞争产品比具有比较高的膜通量。

沸石膜

特点3.高耐酸性

ZX0(NaA型沸石膜)通常只能适用在弱酸性pH6.5~8.5情形,适用的范围非常窄,可能因此而失去订单。特别是在医药・化工领域中比较常见酯化反应中,经常使用硫酸等催化剂。ZX1、ZX2提高了耐酸性,扩大了使用范围。
