    Description / Table of Contents: Oxidative rancidity is a major cause of food quality deterioration, leading to the formation of undesirable off-flavours as well as unhealthy compounds. Antioxidants are widely employed to inhibit oxidation, and with current consumer concerns about synthetic additives and natural antioxidants are of much interest. The two volumes of Oxidation in foods and beverages and antioxidant applications review food quality deterioration due to oxidation and methods for its control. The second volume reviews problems associated with oxidation and its management in different industry sectors. Part one focuses on animal products, with chapters on the oxidation and protection of red meat, poultry, fish and dairy products. The oxidation of fish oils and foods enriched with omega-3 polyunsaturated fatty acids is also covered. Part two reviews oxidation in plant-based foods and beverages, including edible oils, fruit and vegetables, beer and wine. Oxidation of fried products and emulsion-based foods is also discussed. Final chapters examine encapsulation to inhibit lipid oxidation and antioxidant active packaging and edible films. With its distinguished international team of editors and contributors, the two volumes of Oxidation in foods and beverages and antioxidant applications is standard references for R&D and QA professionals in the food industry, as well as academic researchers interested in food quality. Reviews problems associated with oxidation and its management in different industry sectors Examines animal products, with chapters on the oxidation and protection of red meat, poultry and fish Discusses oxidation of fish oils and foods enriched with omega-3 and polyunsaturated fatty acids.

    Description / Table of Contents: The breakdown of food structures in the gastrointestinal tract has a major impact on the sensory properties and nutritional quality of foods. Advances in understanding the relationship between food structure and the breakdown, digestion and transport of food components within the GI tract facilitate the successful design of health-promoting foods. This important collection reviews key issues in these areas. Opening chapters in Part one examine oral physiology and gut microbial ecology. Subsequent chapters focus on the digestion, absorption and physiological effects of significant food components, such as lipids, proteins and vitamins. Part two then reviews advances in methods to study food sensory perception, digestion and absorption, including in vitro simulation of the stomach and intestines and the use of stable isotopes to determine mineral bioavailability. The implications for the design of functional foods are considered in Part three. Controlling lipid bioavailability using emulsion-based delivery systems, designing foods to induce satiation and self-assembling structures in the GI tract are among the topics covered. With contributions from leading figures in industry and academia, Designing functional foods provides those developing health-promoting products with a broad overview of the wealth of current knowledge in this area and its present and future applications. Reviews digestion and absorption of food components including oral physiology and gut microbial ecology Evaluates advances in methods to study food sensory perception assessing criteria such as simulation of flavour released from foods Investigates the implications for the design of functional foods including optimising the flavour of low-fat foods and controlling the release of glucose.

    Notes: Frozen squid is susceptible to both lipid oxidation and yellow/brown discoloration during frozen storage. The involvement of lipid oxidation in the microsomal fraction of squid muscle on oxidative rancidity and discoloration was investigated using iron and either enzymatic or non-enzymatic redox cycling pathways. Lipid oxidation was measured by thiobarbituric acid-reactive substances (TBARS), and color changes were measured spectrophotometrically using an integrating sphere. The lipid oxidation was not observed in the squid microsomes in the presence of Fe3+ and β-nicotinamide adenine dinucleotide disodium salt (NADH) or β-nicotinamide adenine dinucleotide phosphate, reduced (NADPH), suggesting that the enzymatic redox cycling pathway was not active. Iron-promoted TBARS formation was observed in the non-enzymatic pathway when ascorbic acid was used as a reducing compound. Non-enzymatic lipid oxidation increased with increasing temperature (4 °C to 37 °C), iron (0 to 100 μM), and ascorbic acid (0 to 200 μM) concentrations. As lipid oxidation in the microsomes or isolated microsomal lipids increased, color changes were observed as could be seen by an increase in b* values (yellowness) and a decrease in a* (redness) values. The ability of iron and ascorbate to promote both lipid oxidation and pigment formation in the microsomal fraction suggests that this pathway could be responsible for quality deterioration of squid muscle during storage.

    Notes: To better understand the mechanism by which camosine inhibits myoglobin oxidation in salted ground pork, interactions of camosine with ferrylmyoglobin (ferMb), metmyoglobin (metMb) and oxymyoglobin (oxyMb) were investigated. Camosine (0–50 mM pH 5.0–7.5) accelerated the conversion of metMb to oxyMb at pH ≥ 7.0 and carnosine concentrations ≥ 25 mM. Camosine (1–50 mM) also accelerated the conversion of oxyMb to metMh with its formation rates increasing with decreasing pH and increasing camosine concentrations. Camosine (1–25 mM) inhibited ferMb-catalyzed oxidation of phosphatidylcholine liposomes 16–76% and reduced the ferMh electron paramagnetic resonance signal 24–43%. Results suggested that the color stabilizing effects of camosine were related to its antioxidant activity.

    Notes: Analysis of a soluble fraction (press juice) from mackerel muscle indicated 8% of the iron and 7 to 38% of the copper was associated with fractions with molecular weights of 〈 10 kilodaltons (KD). Storage of mackerel muscle resulted in an increase in 〈 10 KD iron but not copper. Storing frozen-thawed muscle resulted in increases in both the 〈 10 KD iron and copper. Storing mackerel resulted in decreased ascorbate and increased hemin in the press juice. Separation of the press juice into 〈5 KD and 〉5 KD fractions indicated both low and high molecular weight components are required for maximal lipid oxidation in mackerel muscle.

    Notes: Ground pork and beef were heated to internal temperatures of 35, 50, 60, 70, 80, 90C to determine the effect of cooking on antioxidant enzyme activity and the development of lipid oxidation. The activity of catalase (CAT) decreased over 85% (compared to uncooked meat) in both pork and beef cooked to 60C. Glutathione peroxidase (GSH-Px) activity decreased 97 and 83% in pork and beef, respectively, cooked to 80C while superoxide dismutase (SOD) activity was not observed to decrease until an internal temperature of 90C was reached. The development of thiobarbituric acid reactive substances (TBARS) increased rapidly in stored meat which had been cooked to 70C or greater suggesting that the inactivation of GSH-Px and CAT could be partially responsible for the development of lipid oxidation in cooked meats.
