Simultaneously, there was no significant difference in hardness. However, the cooking method did not affect the whiteness of instant rice. The volume expansion of BPC after rehydration in boiling water for 3 minutes is presented in Table 1. These results revealed that cooking method and drying with industrial microwave oven did not affect the volume expansion of rehydrated instant rice which is similar to the results of Prasert and Suwannaporn. From Table 1, it was found that the volume expansion of instant rice with the industrial microwave oven is less and this was consistent with Jiao et al., (2014), who found rapid drying resulted in less volume expansion.
They tested how the temperature would affect the rate of reaction. This was observed by the amount of time it took for the solution to change colors. For many chemical reactions there is an optimum temperature at which the chemicals will react with each other. As was found in their experiment, the temperature affected the rate of reaction. (Deoudes, 2010).
The solvent system used for analysis was 10 mM NaOAc/ 150 mM NaOH and the kestoses were eluted at a flow rate of 1 mL /min. 3.2.2. Investigation of reaction parameters There are certain reaction conditions that may favour the production of one kestose isomer over the other. Therefore, several parameters (pH, temperature and time) were chosen and investigated to develop the optimum reaction conditions for each of the kestoses. The experiments for each parameter was carried out in triplicate.
List of synthetic rubber types-What is synthetic rubber? What is Synthetic Rubber? Certain chemicals are added in native form of rubber it is called synthetic rubber.It is used in making different products as a substitute of natural rubber. The use of bicycles expanded in the1890s, and particularly their tires.This started increased demand for rubber. In the history rubber prices and worth started to enhance by 1925 the price of natural rubber.This increament was as fast that many companies started to produce synthetic rubber to compete with natural rubber.
It also comprise minerals such as potassium, phosphorus and calcium in reasonable amounts. Therefore, rice bran can be utilized substantially as a substrate without further addition. Rice husk used for enzyme manifacturing by solid state fermentation comparise cellulose (35%), hemicellulose (25%), and lignin (20%) and it is a good source of lignocellulosic biomass that may be used as rough material . For many these explanations solid state fermentation is approved as a encouraging technique for commercial scale assembly of α-amylase enzymes. Fungal sources have been found for α-Amylase assembly through submerged and solid state fermentation.

Sterilization methods can act in physical or chemical manners, so many different approaches are used to achieve sterilization (Weebly). The most effective physical methods usually involve heat, this can ensue with moist or dry heat. Moist heat sterilization is done at the boiling point of water and will not result in killed spores, but instead
The Viscometer was replaced with the Rheometer so that other rheological properties of crude can also be studied after magnetic treating. 2. Florescence Microscope (see figure 6) was used to study the effect of magnetic field on the crude at the microscopic level (see Figure 7 & 8). The procedure of the experiment was described below: 1. The crude sample was heated at the 46° C in the hot air oven (see Figure 9) and the temperature of water bath was kept at 50° C in order to maintain the constant temperature during magnetic treating.
The solid particles along the dispersion medium are fed into the colloidal mill. The mill consists of two steel plates nearly touching each other and rotating in opposite directions with high speed (7000 rev/min). (B) By peptisation: The process of converting a freshly prepared precipitate into colloidal form by the addition of suitable electrolyte is called peptization. The electrolyte is used for this purpose is called peptizing agent or stabilizing agent. Cause of peptisation is the adsorption of the ions of the electrolyte by the particles of the precipitate.
Later on polymers were used by the humans as a resource of different basic requirements of a life such as clothing and shelter. After that the naturally occurring polymers were made more efficient by humans. Thomas Hancock modified the polymer rubber with the help of ceatrain additive in the ninetieth century. Charles Goodyear similarly improved the properties of natural polymer that is rubber with the help of the element Sulfur. After the improvement of natural polymers, efforts began to produce synthetic polymers.
