Abstract This study compared the effects of conventional thawing methods (water immersion thawing (WIT, (25±1) °C), natural air thawing (AT, (25±1) °C, relative humidity (RH) (65±2) per cent), refrigerator thawing (RT, 4 °C, RH (80±2) per cent) and low-temperature (LT) combined with high-humidity thawing (LT, –1 °C to 1 °C (LT–1–1), 2–4 °C (LT2–4), 5–7 °C (LT5–7) and 8–10 °C (LT8–10), RH≥95 per cent) on the water-holding capacity, lipid oxidation and biochemical properties of Portunus trituberculatus (P. trituberculatus) myofibrillar protein. The results showed that WIT and AT significantly decreased the water-holding capacity while dramatically increasing lipid oxidation, protein oxidation and degeneration, resulting in serious P. trituberculatus quality deterioration. High humidity was beneficial for P. trituberculatus thawing. The thawing time of P. trituberculatus under the conditions of LT2–4 was only 39.39 per cent of that of conventional air thawing at 4 °C (RT), and the LT2–4 samples not only maintained better water-holding capacity but also had an obviously reduced degree of lipid oxidation, protein oxidation and denaturation. Thawed samples LT2–4 and LT5–7 provided better maintenance of P. trituberculatus quality than the LT–1–1 and LT8–10 samples. The best quality was exhibited after thawing at 2–4 °C. The levels of thiobarbituric acid reacting substances, carbonyl content and surface hydrophobicity observably decreased in these samples, while the total sulfhydryl contents dramatically increased compared to those of conventionally thawed samples, indicating lower lipid oxidation and protein oxidation. Moreover, the Ca2+-ATPase activity of the sample thawed at 2–4 °C (2.06 μmol Pi/mg prot/h) was markedly higher than that of samples subjected to WIT and AT. The product qualities observed after thawing at –1 °C to 1 °C, 5–7 °C and 8–10 °C under LT were comparable to that observed by RT. Considering its thawing efficiency and product quality, LT is a suitable method for the thawing of P. trituberculatus, and the ideal thawing conditions were LT at 2–4 °C.

ABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh penambahan minyak buah merah (MBM) pada pakan terhadap kualitas fisik daging ayam broiler. Seratus ekor ayam broiler umur sehari (DOC) ditempatkan pada lima kelompok perlakuan pakan yang berbeda, yaitu: P1 (pakan kontrol/tanpa penambahan minyak), P2 (2% MBM), P3 (4% MBM), P4 (6% MBM) dan P5 (6% Minyak kelapa sawit). Setiap kelompok perlakuan terdiri dari empat ulangan masing-masing dengan lima ekor. Ayam broiler dipelihara selama 35 hari. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan analisis variansi pola searah dan diuji lanjut dengan Duncan’s New Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa semua variable yang diamati menunjukkan adanya pengaruh nyata (P<0,05) terhadap perlakuan yang diberikan. Dari hasil penelitian ini dapat disimpulkan bahwa penggunaan minyak buah merah (MBM) dalam pakan mampu memberikan pengaruh terhadap pH Daging, Daya Ikat Air (DIA), susut masak dan keempukan daging ayam broiler.Kata kunci : daging ayam broiler, daya ikat air, keempukan daging, pH daging, susut masakABSTRACT The experiment was conducted to study the effect of red fruit oil (RFO) onphysical quality  of broiler chicken. One hundred day old chicken (DOC) were placed in four groups of different treatments, of from levels of RFO (P1 (diet without addition of RFO), P2 (2% RFO), P3 (4% RFO) and P4 (6% RFO) and P5 (6% Palm oil)). The treatment group consisted of fivereplications with five birds each. Broiler chickens were reared for 35 days. Statistical analysis used Completely Randomized Design (CRD) and followed by Duncan’s New Multiple Range Test (DMRT). The results showed that the pH value, moisture content, water holding capacity, and cooking loss was significant differences. It could be concluded that the addition of red fruit oil in the diet give effect  of broiler chicken meat.Keywords: broiler meat, cooking loss, moisture content, pH value, water holding capacity
