Starch sweet process

It is well known that starch-iron complexes are suitable for fortifying bread and flour with iron. The state of iron in flour, dough, and bread was investigated by Leichter and Joslyn.643 Iron salts influence the whiteness of sweet-potato starch, but this effect is variable.644 It was also reported645 that colloidal iron interacts with starch, a process which is used to fractionate starch into three portions The first portion (80% of the total amount) is formed by colloidal iron itself, the second (9% of the total) is formed by iron and electrolytes, and the third portion (11% of the total) is not precipitated at all. [Pg.327]

A many number of modelling and simulation systems have been developed to aid in process and product engineering. In this paper the knowledge based process plant simulation model was developed. On the model development side, the issues of knowledge representation in the form of systematic component composition, ontology, and interconnections were illustrated. As a case study a plant for starch sweet syrup production was used. The system approach permits the evaluation of feasibility and global plant integration, and a predicted behavior of the reaction systems. The obtained results of the this paper have shown the variety quality of syrups simulation for different products. [Pg.289]

The CGTase action was evaluated on cassava starch, sweet potato starch, com starch, and waxy com starch. Substrates concentrations were at 2.5%. Enz5mie, conditions, and quantity were conducted as described above, except that aliquot samples were withdrawn periodically until 24 h. In an independent experiment, starches were gelatinized by autoclave process. The percentage of starch converted into CDs was calculated by ratio of total grams of CDs formed divided per gram of starch and multiplied per 100. [Pg.137]

The Sweet Process or Alkaline Process is an older method of steeping than the sulphurous acid method. The nature of this process is indicated by the name. This method was in use for many years and is in use to some extent to-day. By this process the com was placed in large tanks of lukewarm water to Which alkali had been added. The com in these tanks of alkali was allowed to rot for several days. The putrefaction became very foul and only the starch was used as a commercial product. The remainder of the constituents of com were made useless by the alkali or were destroyed by the putrefaction. A starch of high purity was made by this process but the process was too foul and wasteful to be practiced to any extent. It should be noted that this process utilized a combination of the actions of alkali and of bacteria. Little starch was lost in this form of steeping due to the fact that bacteria are practically helpless in their attack upon the starch granule so long as the starch cellulose wall remains intact. [Pg.175]

Starch Sweet potato has the advantage of remaining as a high starch-producing crop with 30 and 49% greater starch yield than rice, corn, or wheat, respectively, under the same conditions. In China, at the former level process, sweet potatoes are cut up by hand, crushed by machine, and sieved to remove waster such as peel and fiber. The starch is left to settle in a tank and then removed. Water is added to the starch, which is once more sieved and settled. Wet starch is transferred to jute bags and allowed to drip-dry for 1 d, and air-dried outside at ambient temperatures [25]. [Pg.679]

Com symps [8029-43 ] (glucose symp, starch symp) are concentrated solutions of partially hydrolyzed starch containing dextrose, maltose, and higher molecular weight saccharides. In the United States, com symps are produced from com starch by acid and enzyme processes. Other starch sources such as wheat, rice, potato, and tapioca are used elsewhere depending on avadabiHty. Symps are generally sold in the form of viscous Hquid products and vary in physical properties, eg, viscosity, humectancy, hygroscopicity, sweetness, and fermentabiHty. [Pg.294]

When you eat starchy foods, they are broken down into glucose by enzymes. The process starts in your mouth with the enzyme amylase found in saliva. This explains why, if you chew a piece of bread long enough, it starts to taste sweet The breakdown of starch molecules continues in other parts of the digestive system. Within 1 to 4 hours after eating, all the starch in food is converted into glucose. [Pg.620]

Koji process The use of the Koji process is very restricted and apart from this paragraph, it will not be discussed further. The substrates are either starch or the residue of sweet potatoes which are placed in shallow trays. Water is added to a 70% weight ratio. Steaming of... [Pg.132]

Horigome et al. (3J5) reported a PER of 1.9 for protein recovered from an industrial sweet potato starch facility. They were able to increase the PER to 2.5 by supplementing the diets with lysine and methionine. A portion of these amino acids were either destroyed or made biologically nonavailable by the processing operation. The possibility also exists that these amino acids were limiting in the cultivars studied. [Pg.248]

Torres et al. (2006) reported a novel microwave processing technique to produce biodegradable scaffolds for tissue engineering from different types of starch-based polymers. Potato, sweet potato, com starch, and non-isolated amaranth and quinoa starch were used along with water and glycerol as plasticizers to produce porous stmctures. Figure 16.1 shows the manufacturing procedure of microwaved starch scaffolds. [Pg.451]

Corn (maize) syrup is a sweetener derived from corn starch by a process that was first commercialized in the 1920s. Corn syrup is composed of glucose and a variety of sugars described as the maltose series of oligosaccharides. These syrups are not as sweet as sucrose, but are very often used in conjunction with sugar in confections and odier food products. [Pg.1587]

In recent years, the conversion of starch to fructose has become a very important commercial process. High-fructose corn syrup (HFCS) is approximately twice as sweet as sucrose. It is used in soft drinks, canned fruits, lactic acid beverages, juice, bread, ice cream, frozen candies, and so on. HFCS can be obtained from a variety of cereals and vegetables, such as corn, wheat, rice, potatoes, and cassava. Corn is the most important source of HFCS because of low costs and excellent utilities of its by-products, corn meal, oil, gluten, germ, and fiber. [Pg.76]
