Nowadays, one of the main objectives of the fruit and vegetable industry is to develop innovative novel products with high quality, safety, and optimal nutritional characteristics in order to respond with efficiency to the increasing consumer expectations. Various emerging, unconventional technologies e. Some of these technologies can also be used for waste and by-product valorisation. The application of fast noninvasive methods for process control is of great importance for the fruit and vegetable industry. In the last few years, consumers have become more exigent and demand high-quality and convenient food products with natural flavours and taste, free from additives and preservatives [ 1 ].

Irradiation, carried out under conditions of Good Manufacturing Practice, is an effective, widely applicable food processing method judged to be safe on extensive available evidence, that can reduce the risk of food poisoning, control food spoilage and extend the shelf-life of foods without detriment to health and with minimal effect on nutritional or sensory quality. This view has been endorsed by international bodies such as the World Health Organisation, the Food and Agricultural Organisation and Codex Alimentarius. More than 50 countries have given approval for over 60 products to be irradiated. Currently regulations on food irradiation in the European Union are not fully harmonised. However, this initial positive list has only one food category — dried aromatic herbs, spices and vegetable seasonings. Some countries, such as Belgium, France, The Netherlands and the UK allow other foods to be irradiated, whereas other countries, such as Denmark, Germany and Luxembourg remain opposed. Within the UK seven categories of foods are cleared for irradiation to specified doses.

Food safety

Food safety is used as a scientific discipline describing handling, preparation , and storage of food in ways that prevent food-borne illness. The occurrence of two or more cases of a similar illnesses resulting from the ingestion of a common food is known as a food-borne disease outbreak. In this way food safety often overlaps with food defense to prevent harm to consumers. The tracks within this line of thought are safety between industry and the market and then between the market and the consumer. In considering industry to market practices, food safety considerations include the origins of food including the practices relating to food labeling , food hygiene , food additives and pesticide residues , as well as policies on biotechnology and food and guidelines for the management of governmental import and export inspection and certification systems for foods. In considering market to consumer practices, the usual thought is that food ought to be safe in the market and the concern is safe delivery and preparation of the food for the consumer. Food can transmit pathogens which can result in the illness or death of the person or other animals.

Part 2 Contaminants in milk: Pesticides, veterinary residues and other contaminants in milk; Contaminants in milk: Routes of contamination, analytical techniques and methods of control; Good hygienic practice in milk production and processing. Part 4 Safety and quality issues in milk processing: Improving pasteurised and extended shelf-life milk; Improving UHT processing and UHT milk products; Modelling heat processing of dairy products; Removal of bacteria, spores and somatic cells from milk by centrifugation and microfiltration techniques; High pressure processing of milk; Pasteurization of milk with pulsed electric fields; Other novel milk preservation technologies: Ultrasound, irradiation, microwave, radio frequency, ohmic heating, ultraviolet light and bacteriocins; Hazard analysis critical control point HACCP and other food safety systems in milk processing. Consumers demand quality milk with a reasonable shelf-life, a requirement that can be met more successfully by the milk industry through use of improved processes and technologies. Guaranteeing the production of safe milk also remains of paramount importance. Improving the safety and quality of milk provides a comprehensive and timely reference to best practice and research advances in these areas.

The current patterns of food consumption indicate a strong consumer preference for processed food products, as they are very economical and last much longer than fresh products which are not compatible with today's lifestyle. It is, therefore, very important to have a clear understanding of the principles of the processes involved as well as the methods employed to ensure quality standards. Food processing is a shared responsibility of everybody in the complex food chain in providing safe and quality food to the consumers.

The patchwork nature of federal oversight of food safety may make it difficult to ensure that the government is effectively promoting the safety and integrity of the nation's food supply. Fragmented federal oversight of food safety has been a longstanding concern because it results in inconsistent oversight, ineffective coordination, and inefficient use of resources. The safety and quality of the U. But the two primary agencies are:. However, these two agencies do not always coordinate with each other. For example, in a memorandum of understanding, they agreed to coordinate on drug residue testing methods—but have yet to do so.

Food quality and safety are the main targets of investigation in food production. Therefore, reliable paths to detect, identify, quantify, characterize and monitor quality and safety issues occurring in food are of great interest. Food Quality and Safety is an open access, international, peer-reviewed journal providing a platform to highlight emerging and innovative science and technology in the agro-food field, publishing up-to-date research in the areas of food quality and safety, food nutrition and human health. It promotes food and health equity which will consequently promote public health and combat diseases. The journal is an effective channel of communication between food scientists, nutritionists, public health professionals, food producers, food marketers, policy makers, governmental and non-governmental agencies, and others concerned with the food safety, nutrition and public health dimensions.

Journal of Food Quality

Дойдя до конца туннеля, Сьюзан уткнулась в круглую сейфовую дверь с надписью СЕКРЕТНО - огромными буквами. Вздохнув, она просунула руку в углубление с цифровым замком и ввела свой личный код из пяти цифр. Через несколько секунд двенадцатитонная стальная махина начала поворачиваться. Она попыталась собраться с мыслями, но они упрямо возвращали ее к. Дэвид Беккер. Единственный мужчина, которого она любила. Самый молодой профессор Джорджтаунского университета, блестящий ученый-лингвист, он пользовался всеобщим признанием в академическом мире.

Если бы этого не было, температура от трех миллионов работающих процессоров поднялась бы до недопустимого уровня - скорее всего силиконовые чипы воспламенились бы и расплавились. Поэтому такая перспектива даже не обсуждалась. Сьюзан старалась сохранять самообладание. Мысли ее по-прежнему возвращались к сотруднику лаборатории систем безопасности, распластавшемуся на генераторах. Она снова прошлась по кнопкам.

В положении личного помощника директора имелись и определенные преимущества: роскошный кабинет в директорских апартаментах, свободный доступ в любой отдел АН Б и ощущение собственной исключительности, объяснявшееся обществом, среди которого ему приходилось вращаться. Выполняя поручения людей из высшего эшелона власти, Бринкерхофф в глубине души знал, что он - прирожденный личный помощник: достаточно сообразительный, чтобы все правильно записать, достаточно импозантный, чтобы устраивать пресс-конференции, и достаточно ленивый, чтобы не стремиться к большему. Приторно-сладкий перезвон каминных часов возвестил об окончании еще одного дня его унылого существования. Какого черта! - подумал.  - Что я делаю здесь в пять вечера в субботу. - Чед? - В дверях его кабинета возникла Мидж Милкен, эксперт внутренней безопасности Фонтейна.

Статуя без изъянов, которую не нужно было подправлять, называлась скульптурой sin cera, иными словами - без воска. С течением времени это выражение стало означать нечто честное, правдивое. Английское слово sincere, означающее все правдивое и искреннее, произошло от испанского sin сега - без воска.

Росио изо всех сил уперлась руками в его массивные плечи. - Милый, я… я сейчас задохнусь! - Ей стало дурно. Все ее внутренности сдавило этой немыслимой тяжестью.  - Despiertate! - Ее пальцы инстинктивно вцепились ему в волосы.

Бринкерхофф почти физически ощущал, как интенсивно работают клеточки ее мозга. - Помнишь, что случилось в прошлом году, когда Стратмор занимался антисемитской террористической группой в Калифорнии? - напомнила. Бринкерхофф кивнул.

 - У нас внизу работают лучшие программисты в мире. И мы нашими совместными усилиями даже близко не подошли к математической функции меняющегося открытого текста. А вы хотите сказать, что какой-то панк с персональным компьютером придумал, как это сделать. Стратмор заговорил тише, явно желая ее успокоить: - Я бы не назвал этого парня панком.

 - С возвращением, сэр. Вошедший не обратил на его руку никакого внимания. - Я д-думал, - заикаясь выговорил Бринкерхофф.  - Я думал, что вы в Южной Америке. Лиланд Фонтейн окинул своего помощника убийственным взглядом.

Но что попало на газетную полосу. Правда. Самый гнусный Веллингтон из всех, что мне доводилось пробовать. Самая грязная ванна, какую мне доводилось видеть. И самый мерзкий пляж, покрытый острыми камнями.
