1) The discrimination is very simple and can be divided into three aspects:

a.视觉观察即淀粉类餐具为亚光型产品有些淡黄或乳白色。而非淀粉类产品色泽暗黑或青白色。

a. Visual observation indicates that starch tableware is a matte product with some light yellow or milky white color. Non starch products have a dark or bluish white color.

b.气味辩别即同类产品相互摩擦产生热量后淀粉类产品有淡淡玉米糊味或植物香味其它类产品有塑料气味 。

b. Odor discrimination refers to the process of similar products rubbing against each other to generate heat. Starch products have a light corn paste flavor or a plant aroma, and other products have a plastic odor.

c.燃烧辩别即二类产品分别燃烧红火焰为淀粉类蓝火焰为其它类，燃烧后的灰粉用手碾碎后黑色粉沫为淀 粉类产品而粉沫较为浅色的是其它类产品。

c. Combustion discrimination refers to the two types of products that burn red flames for starch and blue flames for other types. The burnt gray powder is crushed by hand and the black powder is turned into starch products, while the lighter colored powder is turned into other types of products.

2）、主要成份有载体树脂。玉米淀粉。偶联剂浸润剂相溶剂等低分子，构成。

2) The main component is carrier resin. Corn starch. Low molecular weight, such as coupling agent, wetting agent, solvent, etc.

3）、漂浮物可能有二种情况造成的

3) There are two possible causes of floating debris

a.润滑剂添加量过大并在加工过程中没有完全脱挥使残渣付于产品表面上造成的。

a. Excessive lubricant addition and incomplete devolatilization during the processing result in residue being deposited on the surface of the product.

b.无机物如滑石粉。重质钙添加量过大而形成的。

b. Inorganic substances such as talc powder. Formed by excessive addition of heavy calcium.

玉米淀粉一次性餐具现状：用玉米淀粉餐具的不多

Current Situation of Disposable Corn Starch Tableware: Not Many Use Corn Starch Tableware

玉米淀粉餐具成本就是高，因为原料贵。不说成本，就说批发价，塑料餐具一般是2毛，而玉米淀粉的到了6毛5，这是行情。生产的技术和流程上都差不多，主要还是因 为玉米淀粉的原料贵。玉米淀粉餐具里的玉米淀粉含量要保证。

The cost of corn starch tableware is high because the raw materials are expensive. Not only the cost, but also the wholesale price. Plastic tableware is usually priced at 20 cents, while corn starch is priced at 65 cents, which is the market trend. The production technology and process are similar, mainly because the raw material of corn starch is expensive. The corn starch content in corn starch tableware should be ensured.
