Effects of juice preservation on carotenoids in goldenberry (Physalis peruviana L.) and orange (Citrus sinensis (L.) Osbeck) (Band 12)


Book Description

Fruits are an important part of a balanced diet because of their high content in vitamins, minerals, dietary fiber, and bioactive compounds. Since the shelf life of fruits is limited due to microbiological, biochemical, and enzymatic reactions, processing and preservation are necessary to ensure food safety and year round availability. The present thesis aimed to investigate the effects of commonly used processing methods for fruit juice and puree production such as thermal pasteurization, alternative pasteurization (HPP, PEF), ultrasonication, and spray drying on the stability of carotenoids in goldenberry (Physalis peruviana L.) and orange (Citrus sinensis (L.) Osbeck). This thesis reveals the potential of ultrasonication as a homogenization technology that could be applied in the fruit juice industry in combination with pasteurization for the improved production of fruit juices and purees rich in potentially bioavailable carotenoids. Moreover, in comparison to commonly used carrier agents for spray drying, cellobiose showed a high potential for the application as innovative carrier material to obtain fruit juice powders with good physicochemical properties while preserving valuable constituents such as carotenoids.

Fruit Oils: Chemistry and Functionality


Book Description

Fruit Oils: Chemistry and Functionality presents a comprehensive overview of recent advances in the chemistry and functionality of lipid bioactive phytochemicals found in fruit oils. The chapters in this text examine the composition, physicochemical characteristics and organoleptic attributes of each of the major fruit oils. The nutritional quality, oxidative stability, and potential food and non-foodapplications of these oils are also extensively covered. The potential health benefits of the bioactive lipids found in these fruit oils are also a focus of this text. For each oil presented, the levels of omega-9, omega-6 and omega-3 fatty acids are specified, indicating the level of health-promoting traits exhibited in each. The oils and fats extracted from fruits generally differ from one another both in terms of their major and minor bioactive constituents. The methods used to extract oils and fats as well as the processing techniques such as refining, bleaching and deodorization affect their major and minor constituents. In addition, different post-processing treatments of fruit oils and fats may alert or degrade important bioactive constituents. Treatments such as heating, frying, cooking and storage and major constituents such as sterols and tocols are extensively covered in this text. Although there have been reference works published on the composition and biological properties of lipids from oilseeds, there is currently no book focused on the composition and functionality of fruit oils. Fruit Oils: Chemistry and Functionality aims to fill this gap for researchers, presenting a detailed overview of the chemical makeup and functionality of all the important fruit oils.




Color Atlas of Postharvest Quality of Fruits and Vegetables


Book Description

The effects of time and temperature on the postharvest quality of fruits and vegetables are visually depicted in the Color Atlas of Postharvest Quality of Fruits and Vegetables. Through hundreds of vibrant color photographs, this unique resource illustrates how the appearance (e.g., color, shape, defects and injuries) of fruits and vegetables changes throughout their postharvest life and how storage temperature greatly contributes to critical quality changes. The book’s extensive coverage describes 37 different fruits and vegetables from different groups that were stored at five specific temperatures and photographed daily after specified elapsed periods of time. Individual fruits and vegetables from the following groups are covered: subtropical and tropical fruits pome and stone fruits soft fruits and berries cucurbitaceae solanaceous and other fruit vegetables legumes and brassicas stem, leaf and other vegetable and alliums Information is provided about each individual fruit/vegetable such as characteristics, quality criteria and composition; recommendations for storage, transport and retail; and effects of temperature on the visual and compositional quality of each individual fruit or vegetable, associated with photos of the appearance at particular times and temperatures. This visual documentation shows how important is to handle fruits and vegetables at the right temperature and what happens if the recommendations are not followed. Also shown is the importance of the initial harvest quality of the fruit/vegetable and the expected shelf life as a function of quality at harvest, storage temperature and storage time. The Color Atlas of Postharvest Quality of Fruits and Vegetables will appeal to a diverse group of food industry professionals in the areas of processing, distribution, retail, quality control, packaging, temperature control (refrigerated facilities or equipment) and marketing as a reference tool and to establish marketing priority criteria. Academic and scientific professionals in the area of postharvest physiology and technology, food science and nutrition can also use the book as a reference either for their study or in class to help students to visualize changes in the appearance of fruit/vegetables as a function of time/temperature.




The Commercial Storage of Fruits, Vegetables, and Florist and Nursery Stocks


Book Description

Note for the electronic edition: This draft has been assembled from information prepared by authors from around the world. It has been submitted for editing and production by the USDA Agricultural Research Service Information Staff and should be cited as an electronic draft of a forthcoming publication. Because the 1986 edition is out of print, because we have added much new and updated information, and because the time to publication for so massive a project is still many months away, we are making this draft widely available for comment from industry stakeholders, as well as university research, teaching and extension staff.
