What the best way to produce polylactic acid?5 answersThe best way to produce polylactic acid (PLA) involves several steps. First, corn is soaked in a 0.3% sulphurous acid solution, then crushed, sieved, settled, dried, and finely ground. Starch prepared from the corn is added to a reaction container and heated, with the pH of the solution regulated through additives. The solution is uniformly mixed using stirring equipment. Glucose is produced by converting the starch into dextrin and oligosaccharide using amylase, followed by further hydrolysis using glucoamylase. Lactic acid prepolymer is prepared by de-watering a lactic acid solution and adding a zinc catalyst, followed by heating and reacting for a specific duration. The lactic acid prepolymer is then subjected to isothermal crystallization, crushing, and reacting with pentaerythritol and p-toluene sulfonic acid in a molecular sieve environment. Finally, the pressure is reduced, and the reaction is continued to obtain the polylactic acid product.

What are the objectives of purification in the production of polylactic acid?5 answersThe objectives of purification in the production of polylactic acid are to increase the purity of the lactide product and to lower the production cost. Purification methods such as rectification, melt crystallization, recrystallization, and reduced pressure distillation are used to achieve these objectives. The purification process aims to obtain lactide with high purity and low carboxyl content, which is essential for the production of high-molecular-weight polylactic acid. Efficient methods of separation and purification, such as reactive distillation and molecular distillation, are being developed to reduce the production cost of lactic acid. Additionally, the use of purification components, such as photocatalysts and other physical purification materials, can enhance the adsorption performance of the polylactic acid base material for air purification.

How is starch extracted from pearl millet?5 answersStarch is extracted from pearl millet using various methods. One method involves milling the pearl millet grains and then precipitating the starch in water. Another method involves using sodium azide, mercuric chloride, or sodium metabisulfite with lactic acid to isolate the starch. Acid can also be used to isolate starch from pearl millet, although it has a hard outer layer. The yield of starch from pearl millet can vary depending on the method used, with different starch yields obtained from different extraction methods. The extracted starch from pearl millet can be further modified using heat-moisture treatment, citric acid, microwave treatment, or sonication treatment. These modifications can affect the properties of the starch, such as amylose content, swelling capacity, gelatinization temperature, and rheological characteristics. Overall, pearl millet is a potential source of starch for various industries due to its properties and suitability for use in pharmaceutical formulations and film formation.

Various factors influence vegetable prices in the Philippines. Smallholder farmers face challenges accessing higher-value markets due to constraints like inadequate infrastructure, fluctuating prices, and limited market knowledge. Trade reforms in agriculture and food items impact prices significantly, with high domestic food prices affecting poverty levels. Losses in the vegetable supply chain, attributed to poor handling techniques and quality requirements, contribute to price disparities between traditional and modern retail chains. Additionally, the presence of trust among supply chain participants enables collaboration, leading to optimal prices for farmers. Social capital plays a crucial role in farmers' decisions and economic outcomes, with those possessing higher social capital tending to be wealthier. These combined economic, social, and environmental factors collectively influence vegetable prices in the Philippines.How does price ceiling and price floor affect food crops pruduction?

Price ceilings and price floors have significant impacts on food crop production. Price ceilings, as seen in agricultural price policies, can distort markets by setting maximum prices below equilibrium, potentially leading to food deprivation. Conversely, price floors, like support prices for crops such as rice and wheat, aim to ensure farmers receive sufficient profits, promoting investment and productivity for food security. However, the overemphasis on input prices and global price volatility can lead to increased production costs, necessitating steep price hikes to maintain procurement levels, causing distortions between crop prices. In Nigeria, price variability of food crops tends to align with inflation rates, emphasizing the need for policies to mitigate inflation effects and manage resource inefficiencies in the sector. Despite various price policies, consumer demand for food grains in Nigeria remains unstable, impacting food security due to factors like market price variations and household income constraints.Cancer cell membrane borospherene for targeted delivery
