Citral and linalool are thought to be the most potent aromatic C59 wnt compounds in citrus fruits, but they do not exceed 3 g/100 g in lemon oil. Fatty acids make up a negligible percentage (about 0.2 mL/100 mL) of citrus oils, and the major fatty acid in lemon oil is linoleic acid (Fisher & Phillips, 2008; Svoboda & Greenaway, 2003). It is widely recognised that most of the essential oils have antimicrobial properties (Emiroğlu, Yemiş, Coşkun, & Candoğan, 2010; Fisher & Phillips,

2008; Suppakul, Sonneveld, & Bigger, 2011; Tsigarida, Skandamis, & Nychas, 2000). Individual components of EO, which are either extracted from plant material such as flowers, buds, seeds, leaves, twigs, bark, herbs, wood, fruits and roots (Bajpai, Baek, & Kang, 2011), or synthetically manufactured, are also used as food

flavourings. The ability of citrus oils to delay spoilage and add organoleptic qualities in food products may be interesting from a commercial point of view (Bajpai et al., 2011; Tunç & Duman, 2011). However, there are few studies evaluating EO compounds used to modify the sensory properties of foods (Gutiérrez, Batlle, Andújar, Sánchez, & Nerín, 2011; Kostaki, Giatrakou, Savvaidis, & Kontominas, 2009). Food processing, heat treatment, concentration, evaporation, boiling, baking and the food matrix effect (Taylor, 2002) can result in learn more a loss of flavour quality. To prevent this loss, active packaging materials can be used. Through of the incorporation of active agents in the polymer matrix, food can be aromatised by an interaction between the package and product. In addition to improving the sensory characteristics of foods, flavouring active packaging can be used to develop new products. From a processing line, you can

obtain products of different flavours with the use of flavouring packaging in the conditioning stage. This is useful in a buy Pomalidomide food industry that relies mostly on incremental innovation for new product launches; there is an increasing awareness in the industry that innovations are needed to remain competitive. The transformation of cereal products from dough to biscuit, for example, is a very complicated process involving numerous mechanisms and many properties that must be controlled, such as colour, shape, aroma and crispness (Perrot et al., 2000). Biscuits are an important class of bakery products that are produced in a large variety of flavours. Every day, new types of biscuits, often with innovative flavours, are launched on the market. The degree of protection required by biscuits is determined to a great extent by their composition and the manufacturing process. However, in general, the shelf life of biscuits depends fundamentally on the barrier properties of the packaging materials used to preserve and protect the product from the ingress of atmospheric moisture and other agents that negatively affect flavour (Alves, Garcia, & Bordin, 1999).
