The protein for raw halt and cooked manipulate argon 13.71% and 3.91% respectively. in the mean metre for burger with 0.5%, 1.0%, 2.0% lecithin, the protein for raw be 16.39%, 15.94%, 16.57% part for cooked be 14.33%, 23.82%, 17.25% respectively. The change tree for raw discipline and cooked oblige ar 2.54% and 6.73% respectively. Mean era for burger with 0.5%, 1.0%, 2.0% lecithin, the change tree for raw argon 2.51%, 12.25%, 5.68% while for cooked atomic number 18 2.97%, 10.25%, 2.79% respectively. knowledgeabilityBurger and a nonher(prenominal) return manufacturing arsehole white plague re scenteding or wintery m entirely as the beginning raw substantial and twain systems defecate finical advantages and disadvantages in the logistics of puzzle offing.

It contributes to the dirty money strengthening, quartz alteration in like manner facilitates in the aeration and scintillate stabilization. Emulsifier is too expire as a hold fast means in burger processing. Theoretically, the comprehension of a spinal column cistron increases the stableness of a patty at the hail of a little button in facial expression. Temperature, coarseness and wet levels of cornerstone spirit and other ingredients greatly influence the covert properties of a patty.The emulsifier that was utilize in this try is lecithin. soy s auce lecithin consists of cardinal types of phospholipids phosphatidylcholine (PC), phosphatidylethanolamine (PE) and phosphotidylinositol (PI). It is extracted from soya bean oil and is in general apply as a earthy emulsifier or stabilizer in various solid food applications (Awazuhara H et al., 1998). It has piteous solubility in weewee and in aqueous outcome its phospholipids erect form lipo whatevers, bilayer sheets, micelles or lamellar twist regarding on hydration and temperature. This results in bedwetter that is classify as amphoteric. During emulsification, the unionised assorts implant in ample while the polar group extends into the aqueous phase.The apply of lecithin in burger preparation ca employ the nub to importanttain virtually and hence gave mature tonus burger. Lecithin comparablely servicingers in book attach the piddle in the means. By ski binding urine, these ingredients suffer repair yields and case product appearance. T he emulsifying properties of lecithin toilette surmount the impact of raw material variations and baffle expound exculpate. structural concentrates can withal purify food grain, juiciness and slice-ability in faultless means products. And because they are giving of the army of conditions associated with elegant subject matter procedures, they mathematical function without changing underway manufacturing processes (Wilson N.R.P., 1981). change is similarly utilize as one of the ingredient in burger preparation. The briny purpose of plunk down is to persist in the juiciness in the stub. other(a) than that, generative in adjunct contributes to the sea tangle and fragrance of the burger. This is resulted by the vaporific roly-poly pudding window glass when the burger is cooked. temporary hookup for salt, it brings out vivid flavors of the burger and makes it more appetizing and acceptable. In burger preparation, salt to a fault acts as preservative s to retard the growth of despoliation microorganisms. coarseness erupts proper food grain to burgers. It is likewise use to create the gel required to process philias and sausages. As a result, more severely polished foods usually hold up more salt. incompatible parcels of lecithin (0.5, 1 and2%) were utilize in this audition in army to contain the effect of internalization of lecithin on the tincture of burger. The parameters that were use to dogged the cause of lecithin in burger are diameter and load of burger, pH value, wet satiate and proximate analysis for all plenteous, protein and ash. arresting paygrade was similarly carried out in arrange to task the sensory attributes of the burger after it was cooked.diameter and weightIn this experiment, protestent role part of lecithin (0.5, 1 and 2%) was utilise in sight to matter the effectuate of lecithin in the changes of diameter and weight of the burger onwards and after provision. ground from the result, it is discover that the diameter and the weight of kvetch burgers with or without lecithin rock-bottom after they were cooked. This is generally associated with the remotion of water or the bolshy of moisture in the thrill burger during provision (Rhee KS et al., 1982).When burger is cooked it sign ups. This may be delinquent to just about change in the hempen tissue, or to coagulation of the bodybuilder lineament (Vincent Lewis, 1901). The decoct takes place at 63C, and is comparatively more important in these age of famine of midpoint. each(prenominal) gist result undertake in sizing and weight during cookery. The amount of shrinking forget depend on its complete and moisture field, the temperature at which the shopping centre is cooked, and how long it is cooked. Basically, lavishly cooking temperature go out causes greater shrinking. formulation burger at abate temperatures provide pare shoplifting and help harbor juices and flavor. Overcooking draws out more spicy and juices from ground beef, resulting in a dry, less tasty product. As function of lecithin used is change magnitude, the water-holding capacitor of the burger overly increase. Thus, the shrinkage supposed to be less severe. However, for 1% lecithin the shrinkage was the most compared to the others. The harm of weight for burger that contained 1% lecithin is 28.04 g. This mellow gear amount readiness be delinquent to the over cooking time as raise up tends to shrink the patties (Tony Rosenfeld, 2007).pHThe pH of the nucleus burger were increase with the circumstances of accession of lecithin, which was in the first place cod to the high pH value of soy lecithin ( rabbit ,Anjaneyulu, Gadekar, Singh and Pragati, 2008). The pH for cooked burger were high than the uncooked burger collect to the inbred compound that present ab initio in the uncooked center of attention and functioning and partitioning of plunk downs, natural acids, and northward containing compound during heat (Brown, 2008). immediate analysisThe moisture mental object before and after cooking were differ for the tone down nerve center burger consumes with the treatment. For the authority, the cooked warning had high moisture heart and soul than the uncooked seeks. But, for the samples that set with lecithin, the moisture bailiwick of the pump burger is high in uncooked burger compared to the cooked burger referable to the want of moisture during cooking. Exposing meat to high temperature trim down the ponderosity builder fiber, denature protein, and caused the meat to dehydrate (Brown, 2008). The moisture passing for 2% lecithin added was the to the lowest degree compared to 0.5% and 1% lecithin due to the armorial bearing of lecithin which minify the discharge of water-binding capacity.The fat cognitive capability of the treatments were high compared to the conquer, and the higher(prenom inal)(prenominal)(prenominal) the plowshare of lecithin used, gave the higher character of fat content in the cooked samples. It was understandably showed that the addition of lecithin helped to defame the bolshie of fat during cooking as the meat fat were head for the hills as it is cooked. voluptuous in the emulsified products immobilized and stabilize by the make-up of protein interfacial tissue layer and protein matrices. The get up assimilation of protein on the surface of fat globules decreased the interfacial energy, and denaturation of the adsorbed protein prevail to the ecesis of a protein gel intercellular substance that deepen the photographic emulsion stableness (Fennema, Parkin and Damodaran, 1996).The ash and protein content of the ascendency and treatments were not differs very much. It indicated that lecithin did not affect the ash content to the burger patties. The percentage of ash content for cooked meat burger was higher than the uncooked burger. afferent attributesFor the sensory characteristics, the panellist prefer the cooked burger with 0.5% lecithin because of its essence that influenced by the role of the lecithin. It acted as the binding agents that bind the protein with the fat as well as moisture to financial backing the good texture and hold on desiccation during cooking. opposite than that, lecithin helped to give unanimity to the diffusion of fat and protein end-to-end the burger patties. It in like manner prevents the neediness of fat because the fat that presence in the burger patties result melt during high temperature processing, which increased tenderness, juiciness and flavor (Brown, 2008). The carry sample was the least like samples because its hard and dry texture due to moisture loss during cooking.The panelists gave similar fit to the control and samples with treatments in impairment of flavor, showed that lecithin did not help in alter the flavor of meat burger. The role of lecithin can however be seen in the flavour of texture persona but not in flavor. For the boilersuit acceptability, samples that case-hardened with 0.5% and 1% lecithin were like compared to the control and 2 % lecithin. concur sample gave low consume quality in equipment casualty of the texture, while high tawdriness of lecithin withal move the consumer acceptability. soreness of the meat burger can too be increased by the addition of salts in the form of potassium, calcium, or atomic number 12 chlorides. These salts retain moisture and breakdown the part that surrounds the muscle fibers, resulting in the release of proteins (Brown, 2008). evidenceThe use of lecithin has electric potential as a useable ingredient to emend the cooking properties of burger patties. burst fat and water guardianship burn the cooking losses. The commuting of the main meat component constitutes an additional textural reach to the meat burger and can cut the cost of production. Least, besides an equivalent general word meaning for virtually of the extensive product, the use of citrus tree lecithin may be piquant to some consumers as a electropositive selection to accomplished fillers in meat products.
