摘要：Clean labeling has been a trend and the term “clear label” incorporates the concept of transparency. Thus, this review aims to search in the literature for a better way to extend the shelf life of bread by using ecologically preservation techniques as alternatives to chemical additives. In spite of modern advances in technology, the preservation of foods is still a debated issue, not only for developing countries but also for the industrialized world. There is a increased interest in biopreservation, aiming to extend the shelf life and enhancing food safety by using natural microbiota and/or antimicrobial compounds. The use of natural preservatives would enable bakeries to market the ‘clean label’ or ‘label friendly’ products. Thus, the free-from trend leads the bakery industry to reconsider the traditional preservation methods and replace chemical preservatives with natural alternatives to guarantee the clean label. This process is based on the tendency in dairy category, which coincide with manufactures that incorporate no artificial/all natural/GMO free/BPA free claims on products. In this sense, consumer awareness of food ingredients and the desire for simple, natural foods have forced food manufacturers to develop products with a clean label appeal. It is therefore critical to consider the implications of developing a clean-label product, taking into account the effects such a change may have on sensory quality and microbiological control, while also maintaining regulatory compliance.
