all of the food products are required to be packaged due to hygienic regard, storage, suitable transportation and preservation of quality and vacuum packaging is one of the prevention methods of spoilage. hence in this study, some of the quality factores changes of rutilus frissi kutum fillets storaged in vacuum and air packages were examined during 18 days in ice alike total volatile base-nitr...

The fresh mackerel was frozen using four different quick-freezing methods, such as refrigerator freezing, quick freezer spiral tunnel freezing and plate freezing. Water retention, color, texture, electrical conductivity, total volatile base nitrogen (TVB-N), K value, malondialdehyde (MDA), sulfhydryl group protein secondary structure were used physicochemical indicators to evaluate the changes ...

Oysters are bivalve molluscs in the family Osteridae of the order Ostereoida and are found throughout the world. Quality of stored muscle of oyster, Crossostrea glomerata depends on the temperature and storage time. Investigation on factors responsible for spoilage of oyster meat in refrigerator (7±2°C); in term of biochemical indices, indicated that in 1-2 days the following changes...

In this paper we provide an analysis of monotonicity properties for linear multistep methods. These monotonicity properties include positivity and the diminishing of total variation. We also pay particular attention to related boundedness properties such as the total variation bounded (TVB) property. In the analysis the multistep methods are considered in combination with suitable starting proc...

A puberal change in the secretory pattern of androgen was investigated in the rat. Using immature and adult rats which received an acute human chorionic gonadotrophin(HCG) stimulation, androstenedione and testosterone were measured both in the testicular venous blood(TVB) and in the testis by means of gaschromatography after preliminary separation by paperchromatography. In contrast to the adul...

the effects of grape pomace extract (0, 2 and 4%) on quality and shelf life of silver carp ( hypophthalmicthys molitrix ) fillets during chill storage (4°c) were investigated. the control and the treated fillets were analyzed periodically for microbiological (tvc and ptc), chemical (tvb-n), and sensory characteristics. the results showed that grape pomace-treated samples have lower tvb-n (24.2 ...
