Effect of previous chilling storage on quality loss in frozen (–20 °C) sierra (Scomberomorus sierra) muscle packed with a low-density polyethylene film containing butylated hydroxytoluene

Rancidity development during frozen storage (–20 °C) of sierra fish (Scomberomorus sierra) was studied. Fillets were packed in low-density polyethylene films with and without butylated hydroxytoluene added (BHT-LDPE and LDPE respectively). Fillets stored with no package were used as control. Special attention was given to the effect of previous ice storage (0, 3, 6, 9 and 15 days) on the quality of the frozen fish. Physical (pH and texture) and chemical (peroxide value, PV and thiobarbituric acid index, TBA-i) analyses were carried out. Lipid oxidation increased with ice storage time in fish muscle without film packing, being greater than the film packed muscle (with and without antioxidant). An effect of previous ice storage time was observed on the frozen product (in all treatments). However, fish muscle with film packing containing antioxidant showed less lipid deterioration. Under the conditions applied in this study, the plastic films with antioxidant prevented the lipids oxidation during the cold handling of the sierra muscle.

Residence Model

Model layout of the 3 stage residence expansion to the university proposed in September of 1967. This was a revision of the original master plan which called for high rise residences east of the Tower rather then the sprawling residences shown here. Although modified slightly from the model, the first stage of the residence would become a reality in the form of the Decew Residence. The realization of the second stage would also eventually take place when the Gordon and Betty Vallee Residence was constructed.

Decew Residence Construction

The Decew Residence was the first on-campus residence constructed and replaced the temporary student residences on Glenridge Avenue at the base of the escarpment. The Decew residence accommodated 400 students, and included a 300 seat dining hall, 10 activity rooms and 5 student lounges. Construction completed in 1970.
