Abstract

The development and introduction of healthier products into the marketplace is an important topic of discussion. Three main knowledge areas are involved: gastronomy, food science and technology, and nutrition. The many intersections among these areas are essential since the digestion of nutrients and bioactive compounds can be influenced by thermal food processing and preparation. Conversely, nonthermal technologies are interesting alternatives to reduce and even prevent the loss of nutrients and bioactive compounds from foods. However, at this stage of development little is known about the impact of these innovative nonthermal technologies on the subsequent bioaccessibility and bioavailability of nutrients and bioactive compounds. There are some challenges in the use of nonthermal technologies on a large scale by the food industry, particularly the lack of specific regulation for such technologies, especially in Europe. In this introductory chapter, the basic concepts of food processing, preparation, and nonthermal technologies will be presented.

1.1 Introduction

A diverse and balanced diet, along with healthy choices, is considered as one of the necessary actions to maintain wellbeing and reduce the risk of diseases (Aranceta Bartrina et al., 2016; Musina et al., 2017). The World Health Organization (WHO) recognizes the importance of diet, by means of adequate consumption of nutrients and bioactive compounds, and sets important recommendations for consumers, health professionals, food industries, and researchers. These recommendations are substantiated in a large body of scientific evidence that highlights the importance of eating healthy as preventive action against new cases of the most prevalent noncommunicable diseases worldwide, such as obesity, diabetes, heart disease, stroke, and cancer (WHO, 2013). Due to the importance of diet and the role of food in this context, an important question can be raised here: “How to produce and cook foods in a way to take advantage of maximum nutritional value and natural bioactive compounds already present or subsequently added during production?” Value-added compounds from foods are mainly referred to the concepts of functional foods that can be designed from almost any foods through enrichments, fortifications, and alterations with various extracts obtained from plants or food by-products (Čukelj et al., 2016; Formato, Gallo, Ianniello, Montesano, & Naviglio, 2013; Granato, Nunes, & Barba, 2017; Lorenzo et al., 2018; Montesano, Gennari, Seccia, & Albrizio, 2011; Musina et al., 2017; Naviglio, Gallo, Vitulano, Montesano, & Faralli, 2014; Putnik, Barba, Španić, Zorić, et al., 2017; Vinceković et al., 2017).

This challenging task involves three main knowledge areas: gastronomy (food preparation), food science and technology (food structure and composition as well as processing), and nutrition (digestion, absorption, and efficient use of nutrients and bioactive compounds) (Barba, Mariutti, et al., 2017; Carbonell-Capella, Buniowska, Barba, Esteve, & Frígola, 2014). Each area has a fundamental role to improve food processing and preparation because along with nutritional and health benefits, food properties and characteristics are also influenced (Coveney & Santich, 1997) (Fig. 1.1).

Gastronomy can be defined as the set of knowledge and activities that are related to food ingredients, recipes, and culinary techniques, as well as their historical usage. In other words, it is the outcome of interaction among food and culture. The constant evolution of gastronomy has led us to develop a more scientific approach to food preparation and consumption, formally called molecular gastronomy. This new and exciting branch of food science provides the scientific-based explanations for transformation of physical and chemical properties of food (Caporaso & Formisano, 2016). However, the number of studies evaluating the effects of culinary techniques and nonconventional processing methods on bioaccessibility and bioavailability of nutrients and bioactive compounds is limited. At this stage of development, it is of great importance to have data about bioaccessibility and bioavailability of nutrients and their association with new and conventional processing techniques, as they represent a limiting factor for the development of new and healthy products.

1.2 Culinary techniques

Cooking techniques are a set of methods and procedures for preparing, cooking, and presenting food, which have a key role in the physicochemical and organoleptic characteristics of food as well as food’s nutritional quality. The use of appropriate processing conditions and culinary techniques is essential for the development of nutritious meals and for planning a healthy diet. Food processing and p...
