Paper& Carton Industry

The addition of starch to the wet end of the paper is generally referred to as beater sizing. Here, the primary function of starch is to increase paper strength, to lay surface fuzz and to increase stiffness and rattle of the paper. Practical experience has shown that adding 1% to 2% starch, on the dry weight of the fibre, is quite sufficient to achieve the desired result. Size press application of starch in the paper industry is often referred to as tub sizing or surface sizing. The purpose of size press application is to improve appearance and eras ability, inhibit ink penetration and form hard firm surface for writing or printing and to prepare the sheet for subsequent coating. The size press is chiefly used to improve the writing and printing characteristics of sheets such as bond, ledger, tablet, envelope, chart and business grade. The second important use for surface sizing of paper products is for calender stack and here its main purpose is to enhance surface characteristics such as scuff resistance and printability. Native starches are generally used at concentrations ranging from 2% to 5%. Cornstarch is used as an adhesive in pigment coating for paper and paperboard. The most commonly used pigments are clay, calcium carbonate and titanium dioxide. The primary purpose of coating is to enhance the printability and appearance of the paper. Poultry feed: Characterized poultry feed requirements that large variability in needs and according to the category of birds fed. (Chicken and broiler chickens, laying hens, etc.) pigments to produce the desired color of the skin and egg yolk is another special feature of poultry feed. Feeding stuff of wet corn milling have an important place in meeting these requirements. The most commonly used feed is significantly CGM. It is high in nutrient density and energy value, which is a good source of vitamins and minerals, a senior source in methionine and efficiency Xanthophylls, which are valued for skin pigmentation and the yoke.


 

Application

many foods, which is vital to both the consumer and the food manufacturer, as a major factor that governs the acceptability and palatability of most food products. Corn Starch, because of its abundance and low cost, is used wherever its properties are applicable.
Cornstarch finds numerous uses in the baking industry. Addition of starch makes hard wheat flour preferred for cakes.
Corn starch is used to give proper strength to ice cream cones and sugar water shells. In addition to the above mentioned uses, it finds numerous uses in "dusting" to facilitate certain baking operations. Starch is also used as an inert ingredient in baking powder and also in salad dressing.
In short starch is used by the textile industry in a number of different ways:
As an adhesive in the size mix to strengthen warp yarn and improves its resistance to abrasion during weaving.
In finishing, to change the hand and appearance after it is bleached, dyed and printed.
In printing, to increase the consistency of the printing paste.
As a compound in finishes to glaze and polish sewing thread.
Size is added to yarn to improve the efficiency of the weaving performance and is removed in the first wet processing operation. Since adhesive is the major ingredient of the size mix from the viewpoint of both quantity and price, its choice depends on
How economically it is priced
whether, it offers all the necessary advantages during sizing and can also be easily removed in the usual process of desiring .Of all the starches available commercially, Maize Starch best fulfills the above requirements. It possesses properties superior to native starch as Tapioca and Tamarind Kernel Powder.
Maize Products also manufactures starches suitable for pharmaceutical uses. Such as binder or disintegrating agent in tablets under the trade name 'Corn Starch fulfills all specifications as per pharmacopoeia.
