      In the current study, low pH stress resulted in a decrease in glycogen level but an increase in LDH activity in the adductor muscles of scallops. A similar observation has been reported in C. gigas, where the GLY level in muscle tissue decreased after exposure to low pH seawater . Biochemical components of gonad and adductor muscle for diploid and triploid catarina scallop, Argopecten ventricosus, were evaluated and compared at four periods in 1 year (January, April, June, and October). Two comparisons were done.

    Figure 1 shows the changes of ATP and related products in tilapia fish muscle stored 18 days in ice. The mean Total Molar Concentration (TMC) for ATP and derivatives was ± μmol gThis value is lower than that reported by Murata and Sakaguchi () ( μmol g-1) and by Massa et al. () ( μmol g-1) for yellowtail (Seriola quinqueradiata) and for flounder (Paralichthys.   ABSTRACT The biochemical properties of actomyosin and the expressible moisture of frozen stored adductor muscles of scallop (Zygochlamys patagonica) were investigated. After freezing (zero time of storage) both the enzymatic activity and the reduced viscosity of actomyosin remained unchanged with respect to those corresponding to actomyosin from unfrozen muscles. Both .

    Modifications in shell structure, mantle, and adductor muscle are considered derived adaptations that allowed scallops to swim. This suggests that morphological properties of the adductor muscle and shell should relate to swimming performance in scallops. Various morphological characteristics of the shell (mass, aspect ratio, and volume between the valves) and the adductor muscle (size. Therefore, in the present study, the effects of freezing time on the quality of the adductor muscle of scallops were studied with regard to the integrity of muscle structure, myofibrillar protein denaturation, textural and sensory changes. MATERIALS AND METHODS Scallop meats processing and storage.

Scallop aquaculture owes its commercial success to a global appreciation of the gastronomic delights of scallop striated adductor muscle. Early physiologists were also impressed by the high muscle. Therefore, in this study, four different thawing methods were compared to explore the quality of adductor muscle by comparing the changes in the biochemical properties including pH, ATP-related compounds and the microstructure of scallop adductor muscles after Cited by: 1.

Seasonal changes in the energetic status of the adductor muscle are primarily due to changes in the levels of glycogen (Brokordt and Guderley, a), but may also involve changes in the.

The decline of cellular and especially mitochondrial functions with age is, among other causes, held responsible for a decrease in physiological fitness and exercise capacity during lifetime. We investigated size- and age-related changes in the physiology of exercising specimens of the short lived swimming scallop Aequipecten opercularis (maximum life span 8 to 10 years) from the Isle of Man.

Abstract Scallop aquaculture owes its commercial success to a global appreciation of the gastronomic delights of scallop striated adductor muscle. Early physiologists were also impressed by the high muscle to body weight ratio, the apparent purity of the fibres and the clarity of function of the two main adductor muscles.

Textural and biochemical changes of scallop Patinopecten yessoensis adductor muscle during low-temperature long-time (LTLT) processing Abstract In this study, the effects of low-temperature long-time (LTLT) processing on the quality of Patinopecten yessoensis adductor muscle (PYAM) were investigated at 55°C.

The texture of processed PYAM was. A difference UV-absorption spectrum induced by ATP was observed with scallop myosins purified from both striated and smooth adductor muscles. The difference spectra showed a positive peak at nm with a shoulder around nm, and two small negative troughs around nm.

The commercial importance of this scallop rests principally on the size of the organisms (22 cm tall), weight ( g at 5 years' growth), price (US $16/kg in the international market), flavor, and the production of their adductor muscle.

Each group of sample was treated accordingly to the rearing methods. Post-mortem biochemical changes in invertebrates are known to be different from those in vertebrates,) but no detailed information is available.

In the previous report,4) the authors showed that the post-mortem biochemical changes in scallop adductor muscle differed markedly from. The objective of the present study is to assess the effects of a gradual change in water temperature, an acute change in water temperature, and temperature fluctuations on physiological and biochemical responses, and Hsp70 expression in the Yesso scallop.

Results showed that physiological and enzymatic activities, and Hsp70 expression levels of P. yessoensis were clearly affected by acute.

Scallops possess striated and catch adductor muscles, which have different structure and contractile properties. The striated muscle contracts very quickly for swimming, whereas the smooth catch muscle can keep the shells closed for long periods with little expenditure of energy.

In this study, we performed proteomic and transcriptomic analyses of differences between the striated (fast) and. Kawashima K, Yamanaka H () Effects of storage temperatures on the post-mortem biochemical changes in scallop adductor muscle.

Research studies have reported the effects of low-temperature sous-vide (LTSV) processing on improving tenderness and succulence of mammalian muscle foods.
