This work reports an evaluation and comparison of traditional and novel large scale pasteurisation technologies (pulsed electric fields (PEF) and high pressure processing (HPP)) and consecutive refrigerated storage on the headspace fingerprint of tomato juice. The comparison between technologies was performed based on microbial equivalence. A pilot scale PEF processing system and an industrial scale HPP unit were used in order to imitate industrial application. A fingerprinting approach (‘processomics’) as a hypothesis-free approach has been used for sample comparison, as volatiles are often involved in process- and storage-induced chemical reactions as intermediate or end products. It has been observed, that all three pasteurisation technologies caused loss of several volatiles compared to non-processed sample. Moreover, all three technologies caused increase of Z-citral and 6-methyl-5-hepten-2-one. The majority of the quality-related chemical reactions observed after processing and during shelf-life were oxidative reaction of fatty acids, carotenoid degradation and degradation of amino acids. Industrial relevance Tomato processing often includes thermal treatments, which can adversely influence sensory and quality attributes of the final product. Novel technologies such as pulsed electric fields (PEF) and high pressure processing (HPP) have been investigated and developed as gentle pasteurisation technologies, with a potential to deliver the product with superior quality compared to their thermal counterparts. The results of this study could be of great importance for implementation of novel technologies and could lead to a new product development and process optimisation. In case of PEF technology, the process efficiency might be an important factor, considering that lower energy levels are needed for pasteurisation and higher capacities can be produced (operating in a continuous process) with extremely short holding times at elevated temperature.

This chapter presents an overview of analytical procedures used to isolate the volatile fraction from fresh and processed tomato. Odour unit and flavour dilution analysis are discussed as efficient methods designed to achieve correlation between analytical results and sensorial perception. Major components of tomato fruits and their biogeneration are described. Fatty acids and amino acids can be considered as the main precursors of active odorant molecules characterizing the typical flavour of fresh tomato fruits. Several compounds are derived from intense enzymatic activities as a consequence of fruit comminution, while others are produced during the tomato ripening process. Thermal treatments used in tomato processing lead to a substantial change in the composition of the volatile fraction. In analytical investigation on the Italian tomato variety ‘Pizzutello’, a total of 28 compounds were identified as odour-active compounds.

Evaluating morphological and quality parameters such as shape, colour, size and yield are all common practices when assessing the quality of fruit and vegetables. In recent times, however, consumer interest in foods with high levels of bioactive components, high mineral content and acceptable flavor has increased considerably. In order to make a contribution to the production of fruit and vegetables with excellent morphological properties and high levels of bioactive compounds, two different hybrid tomato varieties (Ege F1 and Alida F1) cultivated in Turkey were compared in terms of their biochemical parameters (phenolic compounds, ascorbic acid, beta-carotene, lycopene, minerals) and volatiles. While the Alida F1 was rated the highest for lycopene and mineral values, the Ege F1 was outstanding in terms of phenolic compounds and volatiles. Ascorbic acid content of both cultivars ranged from 7.13 to 11.94 mg 100 g-1 fw. The quantity in the Ege hybrid was remarkable. Chlorogenic acid, caffeic acid, p-coumaric acid, rutin and trans ferulic acid were the main phenolic compounds in both cultivars. Potassium (K) (4.09%) was the most predominant mineral in both hybrid tomatoes. Hexenal had the highest concentration value among tested volatiles followed by 2-hexenal, (6-methyl)-trans- 5-Hepten-2-one. Comparison of biochemical parameters and volatiles of both varieties will give breeders an opportunity to choose the desired traits of tomatoes to cultivate for both taste and nutritional value.

Plants produce thousands of structurally diverse volatile signal compounds to attract pollinating insects and seed dispersing animals. These compounds are often perceived by humans as a specific fruit or vegetable aroma. Many of these volatiles serve also as defense substances against fungi, bacteria, viruses, and herbivores. The knowledge of precursors and pathways leading to the formation of volatiles in fruits and vegetables has considerably progressed during the last years because of the use of molecular and biochemical techniques. In vitro characterization of the heterologously expressed enzymes has helped clarify the pathways of volatile formation. This chapter will, therefore, provide an overview of biosynthetic sequences and construction mechanisms that are illustrated in most cases using detailed reaction schemes. The various compounds are predominantly ordered according to the biosynthetic pathway that is used in plants to synthesize them and are grouped into carbohydrate-, lipid-, and amino-acid-derived odorants, terpenoids, and glycosidically bound odorants.

A 4-day storage of tomato fruit in refrigerator, a common consumer practice in kitchens, would significant suppress the volatile production in pericarp; however, little is reported on volatile profile in inner tissues. In this study, red ?FL 47? tomato fruits were stored at 5 C or 20 C for 4 days to simulate the major consumer storage types. Inner tissues were sampled immediately after treatments for volatile analysis. Although no visual chilling injury (CI) symptom was observed, refrigeration considerably suppressed the productions of aldehydes, nitrogen- and oxygen-containing heterocyclic compounds, oxygen-containing heterocyclic compounds, esters, and alcohols, including 10 abundant and/or important volatile compounds. Principal component analysis (PCA) and cluster analysis (CA) based on the results of chromatography-mass spectrometer (GC-MS) and electronic nose (e-nose) analysis discriminated the volatile profiles between control and refrigerated fruit, which indicated that volatiles in inner tissue, another contribution to tomato aroma, also altered by refrigeration, and confirmed that refrigeration was not recommended to consumers. Practical applications: Due to their characteristic aroma and taste, tomato fruit which is consisted of pericarp and inner tissues is one of the widely grown and consumed fruit in the world. A 4-day refrigeration of tomato fruit is a common consumer practice in home kitchens; however, little is reported on the impact of such practice on aroma quality in inner tissues. This study provided valuable information on volatile profile in inner tissue of red ?FL 47? tomato fruit and the aroma change in this tissue after 4-day refrigeration.

In the present study, the influence of production systems (net-house and open-field) on volatile profiles of three Texas A&M University (TAMU) and five commercial tomato varieties was investigated. Forty metabolites were determined using headspace solid phase microextraction (HS-SPME) equipped with gas chromatography and mass spectrometry (GC?MS). The data was evaluated by multivariate analyses to discriminate the effects of genotype and production system, and to identify potential biomarker(s). The levels of hexanal, p-cymene, and (E)-2-hexenal from TAMU varieties were distinct from those of commercial tomato varieties. Similarly, 16 metabolites were considerably affected by the production systems, and majority of these volatiles were significantly higher in the net-house-grown tomatoes. Multivariate analysis also allowed identifying geranylacetone and D-limonene as potential biomarkers to classify tomatoes according to production systems. These findings underline the importance of the selection of variety and production system to preserve or improve desirable aroma traits in tomatoes.

Flavour, comprised of aroma and taste, is an important food quality attribute. The aroma or odour of a food product is detected when its volatiles enter the nasal passages at the back of the throat and are perceived by receptors of the olfactory system (retro nasal). The flavour of tomatoes can be characterized by nearly the entire set of their constituents. Indeed, the flavour is not only directly reflected by the sum of the volatile and non-volatile components, but it also depends on their interactions. Solid phase micro-extraction (SPME) headspace sampling combined with gas chromatography (GC), can be used as a reference method for flavour analysis. Another significant factor for buyers and consumers quality is tomato?s colour. After harvesting, ripening continues and tomatoes can become overriped very quickly. This can result in a loss of quality and a reduced shelf life. Tomatoes (Lycopersicon esculentum Mill.) ?loose tomatoes? and ?cluster tomatoes” at red ripeness stage were used. During the experiment the shelf life conditions (atmosphere, temperature and relative humidity) were controlled. Attributes such as colour, size, shape and external defects of fruit and vegetables were investigated in our study because they influence the choice made by consumers. Changes in tomato aroma profiles, dry matter, colour, tytrable acidity, sum of sugars and pH have been monitored at different times and a short-term anoxia treatment of 24 h was applied. Many compounds undergo important concentration changes during shelf life of tomatoes. The HS-SMPE method is useful to evaluate the above mentioned tomato?s changes.

The aroma of fresh-cut produce contributes to product quality and consumer acceptability. Aroma is determined by the composition of volatile compounds released by the product, which is dependent on the product type, genetics, maturity, and postharvest handling. The great diversity of fruits and vegetables provides a wide array of volatile chemistries that contribute to the unique aroma of each commodity. The aroma volatile content of the product at the time of cutting has a major impact on product aroma. Therefore, product maturity, or ripeness in the case of fruit, should be optimized to provide desirable aroma. In addition to volatile compounds produced by the intact commodity, secondary volatile compounds may be produced when products are cut or processed. Postharvest handling, including packaging and temperature management, also impact aroma. The aroma of fresh-cut produce changes as a result of diffusional and metabolic processes during marketing. Cutting removes natural diffusional barriers, and interaction of volatiles with packaging materials can preserve aroma or hasten its loss. Atmosphere modification within packages also alters volatile metabolism. Atmosphere compositions low in oxygen and/or high in carbon dioxide can induce anaerobic metabolism, which may result in off-odor production. The dynamic nature of aroma presents a challenge to design postharvest systems to optimize product aroma and flavor.

N-heterocyclic carbene-catalyzed reactions of alpha,beta-unsaturatedaldehydes and a variety of electrophiles allow the facile preparation o f a diverse array of annulation products including trisubstituted cyclopentenes, gamma-lactams, and bicyclic beta-lactams. The substrate scope of these reactions, however, is limited by the difficulties of preparing the starting alpha,beta-unsaturated aldehydes. We now report that alpha?- hydroxyenones, which can be prepared in a single convenient step from aromatic and heteroaromatic aldehydes, can serve as efficient surrogates for enals in the annulation reactions. This protocol allows the facile preparation and use of substrates bearing nitrogen heterocycles. These reagents have also allowed us to demonstrate that, in contrast to other classes of aldehydes, the formation of the Breslow intermediate from enals and N-heterocyclic carbenes is irreversible under the reaction conditions.
