For tht reson, Herry et l. (1998) pointe out tht the presene of oil is ftor in the isomeriztion retion n the ntioxint in oil protets the trns- n is-lyopene isomers ginst oxition. However, few stuies hve reporte on the use of tomto prouts in met n met prouts (nogn 2002; Yilmz et l., 2002; Sánhez-Eslnte et l., 2003; Ø sterlie n Lerfll, 2005; De et l., 2007). The present stuy resses the utiliztion of ifferent levels of tomto power hete with oil s nturl ingreient in met prouts. The ojetive ws to evlute the ntioxint properties of tomto power (TP) n effets of TP on lipi oxition, olour stility, miroil growth n sensory evlution of proesse pork ptties uring refrigerte storge. MATERIALS AND METHODS Preprtion of tomto power n extrt Fresh tomtoes were otine from the Agriulturl Prouts Wholesle Mrket (Jinju, South Kore). Tomtoes were wshe, ie, n rie for 8 h t 50 in hot-ir rying oven (DM-122SP, Deil Engr. o., Kore). The resulte tomto pste (5 kg) ws mixe with olive oil (140 opyright 2013 y Asin-Austrlsin Journl of Animl Sienes

The rie tomto ws then pulverize using lener (3030, Hsign Feng Enterprise Ftory, Tiwn) n sieve through stinless sieve (40 mesh). The resulte TP ws then sele n kept in -40. This finl TP sore the following olour vlues using spetroolorimeter (R 400, Minolt o., Jpn): lightness (L*) 46.24, reness (*) 8.26, yellowness (*) 6.26. In orer to evlute ntioxint properties of TP, the TP ws extrte using the metho of Br et l. (2006), repete twie, with solvent (hexne: etone: ethnol = 50:25:25, v/v/v) y mertion t room temperture for 4 h. The extrts were filtere (Whtmn No. 1) n evporte- rie (Heiolph, RW-0524G, Germny) elow 45. DPPH free ril svenging tivity Svenging tivity on DPPH free rils y the TP extrt ws ssesse oring to the metho reporte y Gymfi, Yonmine, n Aniy (1999) with slight moifitions. Briefly, 100 L solution of TP extrt t ifferent onentrtions (5 to 100 g/ml) in ethnol ws mixe with 100 L of 0.1 mm DPPH in ethnol. The mixtures were shken vigorously n llowe to stn t room temperture in the rk for 25 min. Blnk solutions were prepre with eh test smple solution (100 L) n 100 L of ethnol while the negtive ontrol ws 100 L of 0.1 mm DPPH solution plus 100 L of ethnol. L-Asori i ws use s the positive ontrol. Therefter, the sorne of the ssy mixture ws mesure t 518 nm ginst eh lnk in spetrophotometer (Ultrospe 2100 pro; Amershm Phrmi Bioteh o., Pistwy, NJ, USA). Lower sorne of retion mixture inites higher ril svenging tivity. DPPH ril svenging tivity ws lulte using the eqution: % svenging tivity = 100-((A s -A 0 )/As ontrol) 100 Where A 0 is the sorne of the lnk, n A s is the sorne of the teste smple. The E 50 vlue represente the onentrtion of the smple leing to 50% reution in the initil DPPH onentrtion. Totl phenoli ontent Totl phenoli ontents of the TP extrt were etermine spetrophotometrilly oring to the Folin- iolteu olourimetri metho (Singleton n Rossi, 1965). Beuse glli i is one of the polyphenol ompouns, totl phenoli ontent of TP extrt ws expresse s mirogrm glli i equivlents /100 g. Totl flvonoi ontent Totl flvonoi ontent of the TP extrt ws etermine using the metho of Me et l. (2005) with minor moifitions. In rief, 0.25 ml of smple (50 g/ml ws e to tue ontine 1 ml of ouleistille wter. Then, 0.075 ml of 5% NNO 2, 0.075 ml of 10% All 3 n 0.5 ml of 1 M NOH were e t 0, 5 n 6 min, sequentilly. Finlly, the volume of solution ws juste to 2.5 ml with oule-istille wter. The sorne of the solution ws etete t wvelength of 410 nm in spetrophotometer (Ultrospe 2100 pro; Amershm Phrmi Bioteh o., Pistwy, NJ, USA). Queretin n uiquitous flvonoi n foun in mny plnt extrts, ws use s stnr to quntify the totl flvonoi ontents. Results were expresse in mirogrm queretin equivlents (QE)/grm. Met ptty mnufture ommeril fresh pork loin n k-ft were otine from lol met mrket, trimme to seprle ft. The len met n the pork k-ft were seprtely groun through 10 mm plte n then through 5 mm plte in hopper (PM-98, MANA, Spin). Groun met n kft were thoroughly mixe with slt, sesoning n ie in mixer (Moel 5K5SS, USA). Sesonings n itives were otine from MS o., Lt. (Seongnm, South Kore). Met ptties were prepre oring to the following formul (%, w/w): groun pork (80), groun ft (10), slt (1.2), pepper (0.3), n istille wter or TP (8.5). Four levels of TP were 0.25% (T1), 0.5% (T2), 0.75% (T3) n 1.0% (T4). All tretments, out 2.0 kg eh, were replite three times from seprte met soures t three ifferent perios. Pork ptties were me with hmurger ptty mker (APAITY HM-10, hin) to e 2 m thik n weight pproximtely 50 g n were ooke in single grill (TG101-E, HOLLAND o., Kore) t 170 for 1 h (until rehing n internl temperture of 75 ).

At 3 n 7 of storge, the TBARS vlues of TP-trete smples were signifintly lower (p<0.05) thn those of ontrol. After 7 ys of storge, the higher the onentrtion of TP in pork ptties, the lower the TBARS vlues in ll teste smples. This result is in greement with previous report (onogn, 2002), who foun tht eef ptties proue without soium nitrite, ut trete with 5%, 10% n 15% tomto pste expresse lower (p<0.05) TBARS vlues thn the ontrol, ue to the ntioxitive tivity of tomto pste.

However, the VBN ontent in the met ptties with TP e ove 0.5% ws lower thn tht of ontrol t storge on 7 (5.94 vs 5.21 mg %). This result represents similr tren to the growth of totl eroi teri in the met ptties. The VBN ontent hs een onsiere s spoilge initor, n is inrese y proteolysis rrie out y miroorgnisms n enzymes in met n met prouts (Fiel n hng, 1969; Jo et l., 2004). These results suggest tht the shelflife of the pork ptties my e improve slightly y 0.5% TP extrt. However, ll the smples for eh group in this stuy i not exee 20 mg/100 g, whih is the vlue tht esrie s the level neessry to etet met spoilge (Su n Lin, 1988). Miroil ounts of pork ptties Figure 1D shows the results for the hnges of totl plte ounts (TP) vlues of pork ptties trete with TP uring storge t 10 1. No signifint ifferene (p> 0.05) ws oserve in TP of ll ptties t 1 of storge. After 3 ys of storge, the TP vlues of, T1, n T2 ptties were signifintly (p<0.05) inrese ompre with initil ounts of TP, however, those of T3 n T4 ptties were not ifferent from the initil ounts of TP. After 7 ys of storge, the TP vlues of ll TP-trete smples showe signifintly lower vlues (p<0.05) thn the ontrol ptties.

The lightness of ontrol, T3 n T4 were not hnge espite week of storge, however, those of T1, T2 were erese (p<0.05) fter 7. Reness of the ontrol ws erese fter 7 in the refrigertor, ut tht of T4 erese, while T1, T2 n T3 ptties showe no hnge in reness even fter 7 ys of storge. This inrese reness resulting from the e TP oul e more ttrtive to onsumers thn the ontrol smple. Applition of lyopene pigment from tomto pste oul improve the pperne of met prouts (onogn, 2002).
