The Relationship

AbstractTo evaluate the relationship between muscle fiber characteristics and the quality of frozen/thawed pork meat, four different muscles, M. longissimus thoracis et lumborum (LTL), M. psoas major (PM), M. semimembranosus (SM), and M. semitendinosus (ST), were analyzed from twenty carcasses. Meat color values (lightness, redness, yellowness, chroma, and hue) changed due to freezing/thawing in LTL, which showed larger IIAX, IIX, and IIXB fibers than found in SM (P < 0.05). SM and ST showed a significant decrease in purge loss and an increase in shear force caused by freezing/thawing (P < 0.05). Compared with LTL, SM contains more type IIXB muscle fibers and ST had larger muscle fibers I and IIA (P < 0.05). PM was the most stable of all muscles, since only its yellowness and chroma were affected by freezing/thawing (P < 0.05). These results suggest that pork muscle fiber characteristics of individual cuts must be considered to avoid quality deterioration during frozen storage.

This study was performed to investigate the quality of fresh wet noodles made from flour milling streams. The basic composition, texture properties, cooking characteristics, and moisture status were measured to evaluate the qualities of noodles. The results indicated that as storage time increased, the springiness of fresh wet noodles gradually decreased, but the hardness increased. Additionally, the cooking loss rate was increased obviously, and the water absorption rate generally decreased. The relaxation times T21 and T22, analyzed by low-field nuclear magnetic resonance, showed a downward trend that proton mobility became poor and bound water changed into intermediate water. Noodles made from reduction flour exhibited better quality. Compared to that with ambient temperature storage, the wet noodles under frozen storage showed better quality. The relaxation time T21, and T22 showed a positive correlation with noodle quality.

Protein Extractability

Refrozen silver hake (Merluccius bilinearis), processed as fillets and minced flesh after thawing of stored round fish that had been frozen within 14 h of capture, underwent rapid deterioration during storage at −18 °C compared with once-frozen control materials from the same lot of fish. The estimated maximum storage life of silver hake refrozen as fillets after 3 and 6 mo storage of the round fish at −25 °C was reduced to about 4.5 and 1 mo, respectively, from 10 mo for once-frozen control fillets. Quality of the refrozen materials immediately after thawing and refreezing was similar to that of the round-frozen fish, except after 6 mo, where some initial deterioration occurred, particularly in minced flesh. Minced flesh was more unstable in frozen storage than fillets. In all once- and twice-frozen materials, formation of dimethylamine occurred concomitantly with decrease in protein extractability. Round-frozen fish underwent no loss in protein extractability during 6 mo storage at −25 °C, but some lipid hydrolysis occurred. These results suggest that the freeze–thaw–refreeze process as applied to silver hake will yield a final product of acceptable quality provided that storage of the round fish does not exceed 3–4 mo and that the refrozen materials are marketed within a month after processing.

. The main objective of this work was to determine the influence of formulation on the stability of bread dough during frozen storage. Bread doughs containing gluten and trehalose were submitted to mechanical freezing at -30° C and stored frozen for 45 days. Two types of instant yeast were tested: (A) for sweet doughs and (B) for savoury doughs. Specific volume was significantly affected by the yeast type, type A showing better effect than type B. Frozen storage of the doughs negatively affected the specific volume, crumb hardness and technological score of the bread. The addition of 5% trehalose had a beneficial effect on the cell survival rate for both the yeasts.

Rejected-duck meat was obtained from old laying duck that unproductive aged 24-26 months. The purpose of this study was to determine the oxidation potential of curcumin extract and its potential in curing rejects the acceptability of duck meat and meat properties during frozen storage. The material used was 36 female rejected-duck the age range 24-26months. The experimental design used was completely randomized design with 3x4 factorial variation. This factor of 0.0 %; 0.1 % ; 0.2 % and 0.3 % curcumin extract and the curing time 5, 10 and 20 minutes. The parameters examined included the acceptability of duck meat cured was determined by the method of Hedonic Test, moisture content , fatcontent, fatty acids and peroxide value of frozen storage for 8 weeks. The results showed that duck meatwas acceptable salvage most of duck meat with curing using 0.3 % turmeric extract with a curing time for 10 minutes. The addition of curcumin turmeric extract the meat of rejected-ducks could inhibit fatty acid peroxidation approximately 39.55 m.eq in frozen storage for five weeks. Water content and fat showed no real difference. However, free fatty acids increased significantly up to 5 weeks. Peroxide value increased until the fifth week of 39.55 %, and then decreased. From thisstudy it can be concluded that the best use extract acceptability of curcumin 0.3 % with long curing 10 minutes, the frozen storagefor8weeks.Keywords: Rejected- ducks meat, curcumin, antioxidant, acceptability and quality of the meat ABSTRAKDaging itik afkir diperoleh dari itik petelur yang sudah tidak produktif yang berumur 24-26 bulan. Tujuan penelitian ini adalah untuk mengetahui potensi oksidasi dari ekstrak kurkumin dan potensinya dalam curing daging itik afkir terhadap akseptabilitas dan sifat daging selama penyimpanan beku.Materi yang digunakan 36 ekor itik betina afkirdengan kisaran umur 24-26 bulan. Rancangan percobaan yang digunakan adalah rancangan acak lengkap pola faktorial 3x4 dengan faktor variasi ekstrak kurkumin 0,0%; 0,1%; 0,2% dan 0,3% dan lama curing 5, 10 dan 20 menit. Parameter yang diteliti meliputi akseptabilitas daging itik curing ditentukan dengan metode Hedonic Test, kadar air, kadar lemak,asam lemak dan angka peroksida penyimpanan beku selama 8 minggu. Hasil penelitian menunjukkan bahwa daging itik afkir yang paling akseptabel adalah daging itik dengan curing menggunakan 0,3% ekstrak kunyit dengan lama curing selama 10 menit. Penambahan ekstrak kurkumin kunyit pada daging itik afkir mampu menghambat peroksidasi asam lemak sekitar 39,55% pada penyimpanan beku selama lima minggu. Kadar air dan lemak menunjukkan perbedaan yang tidak nyata. Namun asam lemak bebas mengalami kenaikan yang signifikan sampai minggu ke 5. Angka peroksida meningkat sampai minggu kelima sebesar 39,55 m.eq, kemudian menurun. Dari penelitian ini dapat disimpulkan bahwa akseptabilitas terbaik menggunakan ekstrak kurkumin 0,3% dengan lama curing 10 menit, pada penyimpanan beku selama 8 minggu.Kata kunci:Daging itik afkir, antioksidan kurkumin, akseptabilitas dan kualitas daging
