    Effect of delayed icing on the storage life of rainbow trout (1986)
    Oxford, UK : Blackwell Publishing Ltd
    International journal of food science & technology 21 (1986), S. 0 
    Details
    ISSN: 1365-2621
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Process Engineering, Biotechnology, Nutrition Technology
    Notes: Rainbow trout (Salmo irideus), were divided into groups: (1) iced immediately, or (2) kept at 10 °C for 6 hr, (3) 20 °C for 6 hr, (4) 20 °C for 18 hr, (5) 30 °C for 4 hr, (6) 30 °C for 6 hr. Fish in groups 2–6 were iced at the end of the stipulated temperature/time period of holding. Quality was subsequently assessed every 2 days for 14 days during iced storage: sensory assessment using criteria of appearance, texture and odour; chemical assessments by measurement of total volatile bases, hypoxanthine and thiobarbituric acid: microbiological assessments by total bacterial counts at 20 °C/72 hr and 37 °C/48 hr incubation. The results indicate that deamination due to bacterial action and hydrolysis of fats increases progressively with rising temperature prolonged periods of storage prior to icing, and results in final spoilage. Fish iced immediately after delivery and those iced after being kept at 10 °C for 6 hr were acceptable to quality even after 14 days of iced storage. Recommendations are made for maintenance of quality and extension of shelf life.

    Thermodynamics of the System InCl3–HCl–H2O at 25° C (1998)

    Notes: Abstract A comprehensive equation for the thermodynamic properties of the system $${\text{InCl}}_{\text{3}} {\text{ - HCl - H}}_{\text{2}} {\text{O}}$$ at 25°C in the ion-interaction (Pitzer) equation form is generated on the basis of a very recent and comprehensive array of electrochemical-cell measurements of the HCl activity, together with older published measurements of the activity of InCl3 in mixtures with 0.02 molal HCl. Alternate equations with and without explicit consideration of the ion pair InCl2+ as a separate species are tested. Excellent agreement is obtained on either formulation between calculated and measured activities, although considerable uncertainty remains concerning the standard potential for the in electrode.

    The thermodynamics of aqueous borate solutions. II. Mixtures of boric acid with calcium or magnesium borate and chloride (1988)

    Notes: Abstract Potentials for the cell without liquid juction $$H_2 ,Pt|B(OH)_3 (m_1 ),NaB(OH)_4 (m_2 ),MCl_2 (m_3 )|AgCl,Ag$$ with M=Ca2+ or Mg2+ are reported over a range of ionic strength at 5, 15, 25, 35, 45, and 55°C. Parameters of Pitzer's ion interaction treatment are determined for Ca(B(OH)4)2 and Mg(B(OH)4)2 by fitting to the cell results. Apparent association of alkaline earth borates to form the monovalent species CaB(OH) 4 + and MgB(OH) 4 + makes it necessary to use the extended β(2) form of the ion interaction treatment to represent the potentials reported here. Trace activity coefficients of calcium and magnesium borates are tabulated at various temperatures and ionic strengths. The association constants for ion pair formation implied by the values of β(2) for these salts are compared with ion pair formation constants available in the literature.

    Notes: Abstract The electromotive force of HCl–Na2SO4 solutions has been determined from 5 to 50°C and ionic strengths from 0.5 to 6m with a Harned type cell $${\text{Pt; H}}_{\text{2}} ({\text{g, 1 atm}})|{\text{HCl(}}m_1 {\text{) + Na}}_{\text{2}} {\text{SO}}_{\text{4}} {\text{(}}m_2 {\text{)}}|{\text{AgCl, Ag}}$$ The results have been used to determine the activity coefficient of HCl in the mixtures. The activity coefficients have been analyzed with the Pitzer equations to account for the ionic interactions. The measurements were used to determine interaction coefficients (β0, β1) for NaHSO4 solutions from 5 to 50°C. The model represents the mean activity coefficients of HCl in the mixtures to ±0.005 over the entire temperature and concentration range of the measurements. The results have been combined with literature data to provide parameters that are valid from 0 to 250°C for NaHSO4 solutions.

    Notes: Abstract Potentials for the cell without liquid junction $$H_2 ,Pt\backslash B(OH)_3 (m_1 ), MB(OH)_4 (m_2 ), MCl(m_3 )\backslash AgClAg$$ where M is sodium or potassium are reported over a range of ionic strength to I=3 mol-kg−1 at 5 to 55°C. Total boron concentration in the solutions was restricted to low levels to minimize formation of polynuclear boron species. Cell potentials are treated with the Pitzer ion interaction treatment for mixed electrolytes, with linear ionic strength dependence assumed for the activity coefficient of undissociated boric acid. Trace activity coefficients of sodium and potassium borates in chloride media are calculated at various temperatures.
