Studies were conducted to evaluate the effects of soy protein concentrate (SPC) and Xanthan gum (X) on physical properties of surimi prepared from Silver carp (Hypophthalmichthys molitrix) using various amount of soy protein concentrate (0, 5 and 10%) and xanthan gum (0, 0.25 and 0.5%) in fish paste during 3 months of frozen storage at -18ºC. Results obtained from folding test showed that the g...

The aim of this study was to investigate the effects of Sodiume alginate edible coating with concentrations of 0/25, 1/25, 0/75 and 1/75% (W/V) on chemical changes of dressed Kilka during frozen storage. Prepared samples of Kilka fish have been coated for 1 h with the dipping method. Coated and uncoated samples have been packed in polyethylene dishes with selphon coverage (75 packs of 250 g). C...

BACKGROUND As a relatively non-regenerative tissue, articular cartilage has been targeted for cryopreservation as a method of mitigating a lack of donor tissue availability for transplant surgeries. In addition, subzero storage of articular cartilage has long been used in biomedical studies using various storage temperatures. The current investigation studies the potential for freeze-thaw to af...

BACKGROUND Assisted reproductive techniques have been used in China for more than 20 years. This study investigates the attitudes of surplus embryo holders towards embryos storage and donation for medical research. METHODS A total of 363 couples who had completed in vitro fertilization (IVF) treatment and had already had biological children but who still had frozen embryos in storage were inv...

Minerals, total phenolics, and fiber were analyzed in several fruit and vegetable commodities to evaluate the differences between fresh and frozen produce. Magnesium, calcium, iron, zinc, and copper were evaluated in corn, carrots, broccoli, spinach, peas, green beans, strawberries, and blueberries. Each commodity was harvested fresh and split into two batches. Half of each commodity was kept f...

Plasma was frozen and stored in different ways before processing to cryoprecipitate by a standard thawing technique. Freezing rate was found to be important with slow freezing having a deleterious effect on cryoprecipitate quality. Storage of frozen plasma at constant temperatures for periods up to six months had no effect on the quality of cryoprecipitate, with no difference being found for pl...

Glycated hemoglobin (HbA1c) has been recently adopted as a diagnostic marker of type 2 diabetes. However, its usage is currently limited to fresh blood samples. To allow retrospective HbA1c measurement in blood banks developed in large epidemic studies, here, we contribute to validate HbA1c assessment in frozen versus fresh blood samples from a cohort of diabetic/nondiabetic adult subjects. HbA...

The effects of the use of essential oil of Rosmarinus officinalis on the chemical quality and fatty acids of fish fillets of Ctenopharyngodon idella were investigated during frozen storage at -18 ºC for 6 months. Fish fillets were divided into three groups the control (C) without rosemary essential, the second group with 0.2 % rosemary essential oil (A) and the third with 0.4 % rosemary essenti...

background: due to high content of unsaturated fatty acids, trout is susceptible to oxidative spoilage. in this study, the effects of thymus vulgaris essential oil (eo) and extract on oxidative stability of cooked rainbow trout fillet during four months frozen storage period were investigated. methods: three groups of fish fillets were treated with thyme eo and three other groups were treated w...

Protein-free filtrates of blood treated with trichioracetic acid were divided into two or three parts. The ammonia concentration of one of these was determined immediately by the ninhydrin method described by Nathan and Rodkey (1). The others were kept frozen for periods of 1-8 days and then thawed and analyzed. The blood ammonia concentrations calculated from these filtrate values were compare...
