Studies On The Protein Changes In Skeletal Muscles Of Gulf Coast Finfish Species Associated With Frozen Storage, Formaldehyde Addition And Freeze-Thawing Cycles., Myrna O. Nisperos-Carriedo

LSU Historical Dissertations and Theses

The effects of frozen storage, formaldehyde addition and freeze-thawing cycles were determined using three finfish species from the Gulf of Mexico, spotted seatrout (Cynoscion nebulosus), black drum (Pogonias cromis) and mullet (Mugil cephalus). Frozen storage of spotted seatrout fillets at $-20\sp\circ$C for 6 weeks led to reductions in pH, water-binding capacity and solubility of salt-extractable proteins. SDS-Polyacrylamide gel electrophoretic examination of the salt-extractable proteins showed that as time of storage increased, aggregation of high-molecular weight components occurred. The addition of 300 ppm formaldehyde prior to frozen storage did not produce significant changes. However, muscles containing 500 ppm formaldehyde showed decreases …

In oyster homogenates, the D values in minutes were 4.7 at 49(DEGREES)C, < 0.35 at 54(DEGREES)C, < 0.35 at 60(DEGREES)C, < 0.33 at 66(DEGREES)C, < 0.30 at 71(DEGREES)C, < 0.29 at 77(DEGREES)C, and < 0.24 at 82(DEGREES)C. In shrimp homogenates, the D values in minutes were 9.17 at 49(DEGREES)C, < 0.43 at 54(DEGREES)C, < 0.39 at 60(DEGREES)C, < 0.32 at 66(DEGREES)C, < 0.31 at 71(DEGREES)C, < 0.30 at 77(DEGREES), and < 0.28 at 82(DEGREES)C. Whole oysters, inoculated with 10('6) V. cholerae/gram, were cooked in boiling water (100(DEGREES)C) or in hot oil (191(DEGREES)C) for one minute. Whole shrimp, inoculated with 10('6) V. cholerae were cooked in boiling water (100(DEGREES)C) or in steam (100(DEGREES)C) for 10 minutes. Vibrio cholerae was not isolated from the cooked oysters or shrimp. Sterile and unsterile shrimp, oyster, crab, and crayfish meat homogenates were inoculated with 10('7) V. cholerae/g. The homogenates were treated with 0, 25, 50, or 100 krad and stored at 4(DEGREES), 0(DEGREES), or -8(DEGREES)C for 21 days. No V. cholerae were isolated from any of the homogenates treated with 100 krad. Vibrio cholerae was able to survive longer in the sterile oyster, crab and crayfish homogenates stored at 4(DEGREES) and 0(DEGREES)C than in the unsterile homogenates stored at the same temperatures. The organism was able to survive longer in the unsterile shrimp homogenates stored at 4(DEGREES) and 0(DEGREES)C than in the sterile homogenates stored at the same temperature. At -8(DEGREES)C, survival time was usually longer in the unsterile seafood homogenates than in the sterile seafood homogenates stored at -8(DEGREES)C. Due to the retardation of competitive inhibition the organism was usually able to survive longer in the unsterile homogenates stored at -8(DEGREES)C than in the unsterile homogenates stored at 4(DEGREES) or 0(DEGREES)C.

Bioavailability Of Iron In Beef And Beef-Soybean Mixtures., Felipe Diez

LSU Historical Dissertations and Theses

In-vivo and in-vitro studies were conducted to measure bioavailability of iron from beef and beef-soy mixtures. The effects of cooking temperature and method of cooking were investigated. Animals absorbed non-heme iron better than heme forms and utilized iron contained in beef-soy diets as efficiently as that contained in beef diets. Colorimetric iron values of 17.18, 6.0, and 9.02% were obtained in raw, broiled and microwaved beef samples, respectively. A similar trend was observed in beef-soy mixtures when analyzed raw (11.03), broiled (6.32) or microwaved (2.21). Iron contained in beef-soy flour mixtures was dialyzed in a larger proportion (16.60%) as compared …


Recovery Of Sugars From Blackstrap Molasses By Ion Exclusion., Edgar L. Aguirre G. Jan 1982

Recovery Of Sugars From Blackstrap Molasses By Ion Exclusion., Edgar L. Aguirre G.

LSU Historical Dissertations and Theses

Ion exclusion is a chromatographic separation of ionic from non-ionic material on a bed of ion exchange resins. This process has been proposed for the recovery of sucrose from molasses. However, separation of sucrose from the non-sugar and reducing sugar fractions is difficult. On the contrary, separation of reducing sugars from non-sugars is relatively easy. Inverting the sucrose to reducing sugars for further separation by ion exclusion gives a way to recover essentially all the sugars from molasses. Also, it eliminates the need for crystallization, since the reducing sugars can be sold in solution. The total sugar content in blackstrap …
