Starch

surrounded by water. Giving the outcome of no liquid. The science behind this is molecules being forced together. When force is applied (or when the cornstarch is punched) the molecules of the cornstarch are forced together and water is trapped between the starch. Later, when force is reduced, the flow of the mixture flows again. The application in the real life of this experiment is in a situation of survival. The same knowledge can be useful in the scenario of being trapped in quicksand.…

High fructose corn syrup is a simple carbohydrate also known as a monosaccharide. Sweet corn kernels are harvested and converted into starch by using caustic soda. Typically, cornstarch is 93% to 96% glucose. Because pure corn syrup is not sweet enough for food manufacturing, food processors add Enzymes to convert glucose into fructose, which changes the molecular structure. The exact ratio of glucose to fructose depends on the manufacturing process. Researchers from Princeton University…

liquid forms liquid bridges while the adhesive will harden or crystallize on drying to form solid bridges to bind the particles. Adhesives such as polyvinylpyrrolidone, the cellulose derivatives (such as carboxymethylcellulose) and pregelatinized starch function in this way. • Crystallization of dissolved substances: when the granules dry, crystallisation of this material takes place and the dissolved substance acts as a hardening binder. Any material in the granulating liquid will function in…

Effect of sugars on starch The effect of saccharides on gelatinization of starch has been observed by many investigators, and the gelatinization characteristics are altered by the sugars addition. The effects of different types of sugars on starch gelatinization depend upon the chain lenght of the sugar. Disaccharides delay gelatinisation more than monosaccharides but maltose is an exception, which acts like a monosaccharide (Dorota Gałkowska, 2008). Sugars have been shown to delay…

Skin test technique: • Skin prick tests are usually performed on the inner forearm. Any number of allergens can be tested, as few as 3 or 4 or up to about 25 allergens. The tested allergens in our study were sodium benzoate and potassium sorbate. • The arm is cleaned with soap and water or alcohol • The forearm is coded with a skin marker pen corresponding to the number of allergens being tested. Marks should be at least 2cm apart. • A drop of allergen solution is placed beside each mark A…

Fig.4.9. The biocellulose production and sugar consumption affected by dibasic sodium phosphate concentrations, incubation period in the steepest ascent experiment 4.6. Production of biocellulose by immobilized G. xylinus cells The aim of the present part of work was to study the influence of immobilization on the production of extracellular biocellulose by G. xylinus. The optimized medium used throughout this expermint was composed of (g/l): reducing sugar, 30; yeast extract, 7; peptone, 7;…

In this experiment I attempted to created and study the affects of a egg in a hypertonic and hypotonic solution. To conduct this experiment I used the following materials: cups, eggs, vinegar, corn syrup, spoons and food coloring. To begin the experiment I placed three eggs in vinegar to dissolve their shells, leaving behind a thin membrane that allowed water to pass in and out of the eggs. The water molecules enter inside the eggs and the eggs begins to swell. Once the eggs have sat in the…

Pound Cake, Patience, Tolerance, Perseverance, & Resiliency Thank you for joining Table Talk with Lawanna sponsored by Progressing through Therapy, www.progressingthroughtherapy.com. In this segment, I will provide how baking a pound cake aided me in developing valuable character traits and values; specifically, patience, tolerance, perseverance, and resiliency. Baking a pound cake is one of the best things that I have produced in my lifetime, so far. I began with a recipe outline not a…

Agar blocks of the stem TR-S1 endophyte were cut from the pure strain actively growing on PDA Petri dishes and transferred to 1 L Erlenmeyer flasks containing a 200 g sized recipe of Corn Grit Agar(CGA). TR-S1 endophyte was incubated at room temperature at 26-28C for 21 days. Fungal metabolites were then extracted by acetone which was then partitioned with ethyl acetate and methanol respectively. TLC analysis of the ethyl acetate fraction revealed the characteristic blue spots of polyketides…

The proximate composition of purple soymilk (Table 1) is not much different from that of yellow soymilk. Purple soymilk has protein, ash, fat, carbohydrate and moisture content 2.76 ± 0.13, 0.12 ± 0.08, 1.17 ± 0.06, 1.27 ± 0.10, and 94.69 ± 0.04% respectively, while yellow soymilk from Tunde-Akintunde and Souley [35] has a protein content of 2.23-3.05%, ash content of 0.24-0.32%, fat content of 1.60-1.94%, carbohydrate content of 1.99-2.78% and moisture content of 92.02-93.29%.
