Abstract
The high consumption of tomatoes worldwide has made them an essential source of health-promoting carotenoids that prevent a variety of chronic degenerative diseases, such as diabetes, high blood pressure, and cardiovascular disease. Tomatoes are available year-round, consumed fresh, and used as a raw material for the production of many processed products, such as juices, pastes, and purees. A plethora of carotenoids has been characterized in tomatoes. Most of the relevant carotenoids in the human bloodstream are supplied by fresh and processed tomatoes. Lycopene is the predominant carotenoid in tomato and tomato-based food products. Other carotenoids such as α-, β-, γ- and ξ-carotene, phytoene, phytofluene, neurosporene, and lutein are present in tomatoes and related products. There is a growing body of evidence that these bioactive compounds possess beneficial properties, namely anticarcinogenic, cardioprotective, and hepatoprotective effects among other health benefits, due to their antioxidant, anti-mutagenic, anti-proliferative, anti-inflammatory, and anti-atherogenic properties. This chapter analyzes the carotenoid composition of tomatoes and their based products as major contributors to the chronic disease-preventive properties.

Abstract
BACKGROUND The objective of the present work was to develop strategies for increasing the shelf-life of red raspberries (Rubus idaeus L.), by preventing microorganism growth. RESULTS Fruits coated with alginate plus lemon essential oil (0.2%) or orange essential oil (0.1%) after 15 days of storage had less red skin than the remaining samples. The less red color verified in these samples was also coincident with the lower concentration of anthocyanins at the end of the experiment as well as the lower capacity for scavenging ABTS free radicals or quenching singlet oxygen. Cyanidin and pelargonidin glucosides were found in raspberries fruits. The edible coatings supplemented with the essential oil of orange either at 0.1% or 0.2% were very efficient for controlling yeast and mold growth after 15 days of storage. To control the development of aerobic mesophilic bacteria the use of essential oil of lemon 0.2% and essential oil of orange 0.1% were the most efficient. CONCLUSION The application of the film improved post-harvest quality of raspberry, since the addition of essential oils of citrus films promoted to the inhibitory effect of fungi and bacteria growth after 15 days of storage, without changing quality parameters. © 2016 Society of Chemical Industry.
