Whole-grain cereals have received considerable attention in the last several decades due to the presence of unique blend of bioactive components like phytochemicals and antioxidants. However phytochemicals and antioxidants in whole-grains have not received as much attention as the phytochemicals in fruits and vegetables, although the increased consumption of whole-grains and whole-grain products has been associated with reduced risk of developing chronic diseases such as cardiovascular diseases, type 2 diabetes, some cancers and allcause mortality. These unique bioactive compounds in whole-grains are proposed to be responsible for the health benefits of whole-grain consumption. In this paper, various whole-grain bioactive compounds and the health benefits associated with their consumption are reviewed.

Kiwifruit is native to Asia and has become popular worldwide due to its sensory and nutritional properties. It contains high levels of bioactive compounds such as vitamin C vitamin E, flavonoids, carotenoids and minerals. Kiwifruits show a wide diversity in size, shape, fuzziness, flesh and peel color and flavor. The export of fresh kiwifruit has led to rapid expansion of kiwifruit industry through out the world. kiwifruit has become a commonly consumed fruit and is easily available round the year. Kiwifruit is largely consumed as fresh but it is also available in processed forms as juices, fortified drinks, candies, dehydrated and lyophilized products. Kiwifruit is also minimally processed to provide consumers with ready to eat products. Different preservation techniques have been used so far to preserve minimally processed kiwifruit. Here we are going to review some of these techniques.

Fermentation is an old age biotechnological technique for preservation of vegetables, which has paved pathway towards nutritional and functional value of the foods. It not only preserves food for long period of time but also increases functional, nutritional and sensory features of food commodities. Fermentation is the outcome of the the microbes which grow in the food commodity with the passage of time. Leuconostoc mesenteroides and related LAB, including Weissella and other Leuconostoc spp. are important in the initiation of the fermentation of many vegetables. Fermented foods are supposed to be rich in the health beneficial probiotics. Fermented vegetables are low-calories foods as they contain considerably lower quantities of sugars compared to their raw counter parts. They are source of dietary fibre, which impedes the assimilation of fats and regulates peristalsis in the intestines and valuable source of vitamin C, B group vitamins, phenolics and many other nutrients.

Green tea is manufactured from the leaves of the plant Camellia sinensis and has been regarded to possess anti-cancer, anti-obesity, anti-atherosclerotic, antidiabetic and antimicrobial effects. The main bioactive components present in green tea are polysaccharides, flavonoids, vitamins B, catechin compounds, fluoride and etc. Among them catechin compounds have been proven to have a variety of physiological functions. Due to the popularity of the health benefits of tea catechins, new products have been developed with tea as an active ingredient such as ready-to-drink (RTD) tea beverages, confections, ice creams, cereal bars and pet foods. This review summarizes several lines of evidence to indicate the health-promoting properties of green tea and their potential to be used in development of foods with added nutraceutical value.
