A Fruit Smoothie Is A Drink Biology Essay

A Fruit Smoothie Is A Drink Biology Essay Fruit and vegetables are not consumed in the required quantities, throughout the world due to a variety of reasons e.g. availability, cost and/or convenience. Even though there importance is clearly defined by the World Health Organisation guidelines (Keenan et al. 2011a), in the developed world convenience is perceived as being the predominant cause for the demise of fruit and vegetable consumption. This has directly led to the development of a new product set – that enables the consumer to achieve the recommended 5 portions a day, whilst maintaining their busy life styles. ‘Smoothies’ have now entered into popular culture; the (Oxford English Dictionary, 2013) defines it as â€Å"Noun – a thick, smooth drink of fresh fruit purà ©ed with milk, yogurt, or ice cream† A fruit Smoothie is a drink that blends fruit and fruit juice together to create a healthy snack. The Smoothie market to have reached $9.0 billion by 2015 (Global Industry Analysts, 201 0) and that UK sales reached 34 million in 2006, which is 6.3 million up on 2001 according to Mintel who also expect Smoothie sales to treble by 2011 (BBC News, 2007). In the USA the sales reached $2 billion in 2012, which has grown 80% over the past 5 years (Smoothie Statistics, 2012). In the UK, the sales of smoothie increase to 80 million in 2007, but showed a reduction in sales gradually falling by 2009, however sales have increased again by 2011 to 55 million (British soft drinks, 2011). Mintel are a company that provide food and drink research to the UK. They have reported that many fruit Smoothies have been found to have a hidden sugar content to sweeten the Smoothie up; many of the fruit Smoothies were found to have hidden sugars comprising of fruit juice concentrates and high fructose syrup (Courier mail, 2013). Most Smoothie’s have apple and banana as core ingredients. Apples have a natural sweetness; this means not as much, if any additional sugar needs to be added to the drink, to sweeten the taste, banana is also added as it adds a natural thickness to the Smoothie, nothing artificial needs to be added to the Smoothie (Innocent drinks, 2013). One problem that is faced is the texture of the drink, it can be quite bitty or grainy, this is derived from tiny particles that some fruits contain, for example strawberries have small pips on the outside of the fruit, so blending the fruit alone will not get the particles to break up. However a way to change this has been found that passing ultrasound waves into the fruit during its preparation makes the particles smaller. Ultrasound wave technology has been available for many years, but in the last 10 years the food industry has developed a methodology to use the ultrasonic waves in food processing (Ultrasonic innovations, 2008). This paper presents an example of using ultrasound waves in the Fruit Smoothie product to reduce the particle size problem outlined earlier. There are a number of advantage s for using ultrasonic waves, they have a more effective mixing and micro-mixing, faster energy and mass transfer, reduction in temperature – the mixture can remain at the same temperature throughout the process. Ultrasound wave technology also increases the production volumes of the Smoothies (Chemat et al., 2011).
