In response to this consumer demand for ‘greener’ food additives, interest in ozone has expanded in recent years. Excess ozone rapidly auto-decomposes to produce oxygen and thus it leaves no residues in food, and is increasingly accepted as environmentally friendly technology. Ozone was affirmed to be Generally Recognised As Safe (GRAS) in contact with foodstuffs by a panel of food experts convened by the Electric Power Research Institute in 1996 and subsequently was approved as an Antimicrobial Agent in direct contact with foods of all types by the U.S. Food and Drug Administration in 2001.
The authors provide a comprehensive overview of ozone processing in the food industry, examining applications for various food groups, including evaluations of the impact on quality and safety values. The authors also address global regulatory and legislative requirements for ozone processing, as well as providing recommendations and opportunities for various health and safety-related issues and suggesting new applications for ozone processing in the food industry.
Ozone in Food Processing is the first book to bring together essential information on many applications of ozone in food processing, providing an insight into the current state-of-the-art applications as well as reviewing established and emerging applications in food processing, preservation and waste management. It will be of interest to food scientists, engineers and microbiologists working in food processing, as well as academic researchers and lecturers in the subject area.

They provide a natural food grade ingredient that is rich in lysine, dietary fiber, complex carbohydrates, protein and B-vitamins suggesting that pulses can provide a variety of health benefits such as reducing heart disease and diabetes. Interest in the use of pulses and their ingredients in food formulations is growing and several factors are contributing to this drive. Pulse Foods: Processing, Quality and Nutraceutical Applications is the first book to provide up-to-date information on novel and emerging technologies for the processing of whole pulses, techniques for fractionating pulses into ingredients, their functional and nutritional properties, as well as their potential applications, so that the food industry can use this knowledge to incorporate pulses into new food products.

Orange juice containing 7g/100g of commercial fructooligosaccharides (FOS) was directly and indirectly exposed to a plasma discharge at 70kV with processing times of 15, 30, 45 and 60s. For high-pressure processing, the juice containing the same concentration of FOS was treated at 450MPa for 5min at 11.5°C in an industrial equipment (Hyperbaric, model: 300). After the treatments, the fructooligosaccharides were qualified and quantified by thin layer chromatography. The organic acids and color analysis were also evaluated. The maximal overall fructooligosaccharides degradation was found after high-pressure processing. The total color difference was <3.0 for high-pressure and plasma processing. citric and ascorbic acid (Vitamin C) showed increased content after plasma and high-pressure treatment. Thus, atmospheric pressure cold plasma and high-pres...

Ozone appears to be a powerful sanitiser which meets the expectations of industry and has the approval of regulatory agencies (Khadre et al. 2001). It is a highly unstable triatomic oxygen molecule that can be generated commercially when oxygen molecules are subjected to a high-voltage electric discharge.

Because its oxidative properties can be used as reaction partners in gas, liquid or solid phases, the applications of ozone are manifold and stretch across a wide range of different industries.

In addition to using these models to understand and describe a process, they can also be applied for control and optimisation purposes. In general, mathematical models offer new possibilities to manage the increasing complexity of the studied technologies and explore solutions in a short time, while reducing costs of operation.

The conjugated bonds in their structures, which absorb light at about 500 nm, are the basis for the red, blue and purple colours of fruits, vegetables and their products. Anthocyanin pigments readily degrade during thermal processing which can have a dramatic impact on colour quality and may also affect nutritional properties.

The purpose of this study is to systematically review research investigating the potential benefits capsaicinoid compounds may have in relation to weight management. Medical databases were searched and 90 trials found, 20 of which were selected for inclusion, involving 563 participants. Three main areas of potential benefit for weight management were found: (1) increased energy expenditure; (2) increased lipid oxidation and (3) reduced appetite. Trial duration, dosage and sized varied, though trials were generally of high quality with a low risk of bias. It was observed that consumption of capsaicinoids increases energy expenditure by approximately 50 kcal/day, and that this would produce clinically significant levels of weight loss in 1-2 years. It was also observed that regular consumption significantly reduced abdominal adipose tissue levels and reduced appetite and energy intake. The mechanism of action is not presently fully understood, although it is well accepted much of the effects are caused by stimulation of the TRPV1 receptor. While capsaicinoids are not a magic bullet for weight loss, the evidence is that they could play a beneficial role, as part of a weight management program.

This study focusses on β-glucan rich fractions from barley and mushroom used in the production of extruded ready to eat snacks. Inclusion of barley β-glucan rich fractions and mushroom β-glucan fractions at 10 % levels increased the total dietary fibre content of extrudates compared to the control (P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.05). Product expansion increased with the introduction of both barley and mushroom fraction (P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.05) which in turn resulted in a reduction in product hardness (P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.05). In vitro digestion protocol illustrated that inclusion of barley and mushroom β-glucan rich fractions manipulated the starch digestibility profile and hence rate of glucose release during digestion compared to the control sample. This in turn resulted in a significant (P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.05) reduction in potential glycaemic response of the samples of between 20 and 25 % for barley β-glucan rich fractions and between 17 and 25 % for mushroom β-glucan rich fractions. We conclude that the inclusion of these fractions could be utilised by the food industry to manipulate the glycaemic response of extruded snack products.

Blood orange juice was processed at pressure levels of 400, 500, 600MPa for a constant treatment time of 15min. During processing &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;99% and 94.5% retention of Cy3Gl and AA content was observed for all pressure treated samples. The degradation kinetics
