Problems solved by technology

[0003] However, the newly emerging mainstream new disposable environmental protection straws on the market all have practical or environmental defects: paper straws have poor water resistance, and the effective time for soaking in normal temperature liquid (25°C) to maintain performance is less than 12 minutes; PLA (polylactic acid , Polylacticacid) straws are fragile and easy to break, and cannot be immersed in hot drinks (≥75°C), and the degradation conditions are harsh, so natural degradation has no practical significance; taking bagasse straws as an example, the natural storage period of each biomass straw is short, only 2- 3 months, inconvenient storage and transportation
Using other materials instead of plastic to make straws has the problems of high technical barriers to heat resistance, water resistance, hardness and toughness

Embodiment 1

[0026] The preparation method of the environment-friendly and degradable environment-friendly straw of the present embodiment is as follows:

[0027] ①After sterilizing and drying the garlic skin, it is pulped by chemical pulping. It is preferable to put garlic skin into the raw material pool under the condition of 160° C. and 16% alkali content, and make pulp by caustic soda method. Wash and balance the moisture after pressing.

[0028] 2. Weigh starch components (including wheat starch (deproteinized), potato starch (deproteinized), pea flour, indica rice flour) according to the corresponding data of Example 1 in Table 1, and mix with water to obtain a consistency of 30%- 50% slurry.

[0029] Table 1: Part of the formula of the degradable environmental protection straw of the embodiment

[0030]

[0031] Note: The wheat starch (deproteinized) in Comparative Examples 1-3 was replaced with ordinary high-gluten wheat starch;

[0032] 3. Weigh sodium monophosphate (food g...

Embodiment 2

[0036] Each component was weighed according to the data of Example 2 corresponding to Table 1, and the environmentally friendly degradable straw of Example 2 was obtained according to the method described in Example 1.

Embodiment 3

[0038] Each component was weighed according to the data of Example 3 corresponding to Table 1, and the environmentally friendly degradable straw of Example 3 was obtained according to the method described in Example 1.

Abstract

The invention discloses an environmental protection straw for garlic skin starch and a preparation method. The components of the straw include: 90-100 parts of wheat starch (deproteinized), 4-8 parts of potato starch (de-proteinized), 2-6 parts of pea flour, 40-50 parts of indica rice flour, 50-55 parts of garlic peel, monophosphoric acid Sodium (food grade) 0.1~0.2 part, sodium tripolyphosphate (food grade) 0.1~0.5 part, sodium trimetaphosphate (food grade) 0.2~0.4 part, sodium polyacrylate (food grade) 0.5~3.5 part, trehalose 3-6 parts, 3-10 parts gellan gum, 1.5-3 parts food coloring. The above-mentioned raw materials are mixed, pulped, mixed with cross-linked starch, and formed into a straw to obtain a straw. The straw is water-resistant, has high hardness and can be naturally degraded.

Description

technical field [0001] The invention relates to an environmental protection straw and a preparation method, in particular to an environmental protection straw of garlic skin starch and a preparation method. Background technique [0002] Plastic straws are harmful to the ecology due to their small size, so in recent years, many new disposable environmental protection straws have appeared on the market. [0003] However, the mainstream new disposable environmental protection straws that have recently appeared on the market all have defects in practicality or environmental protection: paper straws have poor water resistance, and the effective time of soaking in normal temperature liquid (25°C) to maintain performance is less than 12min; PLA (polylactic acid) , Polylacticacid) straws are fragile and easy to break, and cannot be immersed in hot drinks (≥75°C), and the degradation conditions are harsh, and natural degradation has no practical significance; the natural storage peri...
