1, thickening, used when cooking, as for how to thicken, it should be needless to say ~ 2, used when making cakes, so I bought a cake to play with, flour: corn starch =4: 1, which can make ordinary flour into low-gluten flour suitable for making cakes and make it softer. Preparation: eggs, 4 80g flour, 80g sugar 100g milk, 5g baking powder 10g salad oil microwave cake. Steps: (Just replace the flour with the flour prepared above) 1. Mix egg yolk, milk, semi-sugar and salad oil evenly (Figure 1 and 2). 2. Mix the flour and baking powder evenly, pour into the egg yolk liquid and stir evenly (Figures 3, 4 and 5). 3. Add the remaining white sugar to the egg white, pour a few drops of white vinegar, and beat with four chopsticks for 8- 10 minutes until the egg white can stand on the chopsticks and will not fall down when provoked (Figures 6, 7 and 8). 4. Pour the egg white into the yolk paste for three times and gently stir it up and down until it is uniform (Figure 9, 10). 5. Pour a small amount of oil into a special microwave basin, wipe it evenly by hand, then pour in the prepared batter and tap the basin a few times to make the big bubbles burst (Figure 1 1, 12). 6. Put the basin in the microwave oven and turn on the fire for 7 minutes. Take the basin out to dry for a while, buckle it upside down on the chopping board and the cake will fall out. Use of Cassava Starch Cassava starch is widely used in food formulations, such as baked products, and also used to make extruded snacks and cassava beads. Modified starch or starch derivatives have been used as thickeners, adhesives, fillers and stabilizers, and are also the best fillers, sweeteners, flavoring carriers and fat substitutes. Foods using Thai cassava starch include canned food, frozen food, dry mixed food, baked food, snack food, seasoning, soup, sausage, dairy products, meat and fish products and baby food. Beverage modified starch is used as colloid stabilizer in beverages containing solid components. The application of cassava starch sweetener in beverages is better than sucrose, because the former improves the processing technology and strengthens the product characteristics, and can fully meet the needs of consumers when used with other sweeteners. The syrup with high degree of hydrolysis formed by cassava starch hydrolysis is an ideal source of fermentable sugar in beer brewing. Candy cassava starch and various modified starches have many uses in candy production, such as gelling, thickening, stabilizing system, enhancing foaming, controlling crystallization, bonding, forming films, adding luster and so on. Low viscosity tapioca starch is widely used to gel candy, such as frozen and chewing gum. Acid-hydrolyzed starch is the most commonly used, because it has excellent reversibility and gelling ability, and these characteristics are more obvious when sugar is involved. Dry starch is used as a release agent in candy manufacturing. Starch-based polysaccharide realized the production of sugar-free chewing gum. Chemical cassava starch-based syrup can be produced at low cost by acid hydrolysis or enzymolysis, so it can be used as raw materials to produce various chemicals, such as sodium glutamate, amino acids, organic acids, ethanol, ketones, vitamins and antibiotics. Adhesives and glues Cassava starch dextrin is an excellent adhesive with a wide range of uses, including corrugated cardboard, paper bags, plywood, adhesive tapes, labels, stamps and envelopes. The application of papermaking modified starch in papermaking industry can improve paper quality, productivity and pulp utilization rate. Cationic starch is used to flocculate pulp and improve wet-end dewatering efficiency. As a result, a higher paper machine speed can be used, and a higher pulp utilization rate can be obtained. The starch left on the finished paper can be used as an internal sizing agent to increase the strength of the paper. Low viscosity starch, such as oxidized starch, can be used as surface sizing agent to improve paper strength and ink absorption in printing and writing. Modified starch is also used as a binder in pigment coating to produce smooth and white high-grade paper. In the textile industry, cassava starch is often used as a sizing agent to harden and protect yarns in order to improve textile efficiency. Used as finishing agent to produce fabrics with smooth feel; Used as colorant to obtain clear and wear-resistant printed cloth. For textile applications, it is more desirable to use lightly cooked starch. Cassava starch and modified starch can be used as binders, fillers and disintegrants in tablet production. Specially modified starch can be used as a carrier for emollients, which are usually mineral oil-based substances. Other modified starches can be used as emulsifiers, encapsulating agents (vitamins), styling agents (hair gels) and thickening agents (shampoos). Biodegradable materials cassava starch and modified starch can be mixed with petroleum-based or synthetic polymer materials to improve the biodegradability of the materials, thus minimizing the production cost of such environmentally friendly materials.
