Molecular Gastronomy

Literal translation of "AYURVEDA" may be understood as a science to increase life (AYUR). Ayurveda comes under the purview of Atharva Veda that is considered to be one of the four doctrines in Indian Culture and heritage. Essentially this branch of philosophy deals with Medicine and Surgery for the holistic wellbeing of humanity. Charaka Samhita, a codified treatise on general Medicine in classic Ayurveda has been written in Sanskrit during the time of Indus Valley Civilization around 1000 B.C.E. (Before the Common Era). This system of medicine has stood the test of times. It is not only the "how" and "what" we eat makes a difference in our health but how it is prepared does acclaim significance. Centered on this concept, Paatra Shuddhi (purity of vessel), Paaka Shuddhi (purity in cooking process) and Padartha Shuddhi (purity of the ingredients) are proposed by ancient Sages who followed Vedas. Indian cooking with all the taboos of being hot and spicy actually backed up with scientific rationale, with each ingredient added for a purpose and a deep rooted reasoning. It is all about balancing the key forces within our body and understanding the basic requirements to stay fit and healthy. Ayurvedic cooking is based on the understanding of the unique combination of Vata (Ether), Pitta (Fire) and Kapha (Water) that constitute the human body and balance its life forces. Our body is based on one or a combination of these factors. The Ayurvedic cuisine includes dishes made out of such food combination that balances these factors optimally in the human body. As it is a relatively unique concept, it can also fetch the market value in the form of new ventures in various countries. In this article due emphasis is laid up on Rajsic/tamsic/saatvic type of foods as per Ayurveda, basic human elements are revisited and summarized, food preparations related to the balancing of forces and elements of human body are discussed and reasons for following a particular step for the preparation in the cuisine are elaborated. Further this paper throws light on new ingenious business ideas based on Ayurvedic foods and supplements.

Molecular gastronomy (MG) is a relatively new scientific discipline,
which focuses on food preparation mainly at domestic and restaurant
levels. The number of scientific papers on MG has increased in the
past few years. It is, however, difficult to differentiate specifically
between the MG discipline or other research areas in food science
and technology. Otherwise, molecular cooking, i.e., an application of
MG principles, seems limited to a few “fancy” techniques supported
by famous chefs. This paper aims to critically review the recent
developments of MG, the most interesting applications, and the
outcomes obtained from the fruitful collaboration among food scientists
and innovative chefs. The controversies and merits associated
with MG are also presented, e.g., the principle of food pairing and
consumers’ appreciation of innovative dishes, and a few research
papers promising exciting future developments.

Solutions obtained by soaking onion (Allium cepa L.) bulbs samples in water are frequently consumed, either directly or as part of dishes, both at home or in the food industry. However, little information is available regarding the extracted metabolites and the extraction mechanisms. In this article, the composition of raw onion extracts and of aqueous solutions where raw onion tissues were soaked was investigated directly by quantitative proton nuclear magnetic resonance spectroscopy (q 1H NMR). The assignment of NMR signals was performed, with less than 3% (in area) of unidentified peaks. Analyses of one-dimensional 1H NMR spectra with additional two-dimensional NMR studies showed 20 regions of interest where 3 saccharides, 17 amino acids, and 5 organic acids were detected and quantified. Resonance assignment with chemical shift was done for each saccharide, as well as for each amino acid and organic acid, with additional work on spin–spin coupling pattern and on observed and not observed correlations from correlation spectroscopy studies. Quantification of saccharides was performed and qualified by works on peak decomposition algorithms. Complementary studies by high-performance liquid chromatography, mass spectroscopy and tandem mass spectroscopy, and thin layer chromatography and preparative layer chromatography were carried out in order to validate the NMR results on identification.

The aim of our research was to evaluate the effect of different types
of vegetable oils, namely extra virgin olive oil (EVOO), olive oil,
and sunflower oil, on the chemical properties and volatile profile of
traditional Neapolitan pizza, produced by using tomato sauce and
EVOO. The quality indices and polyphenols in vegetable oils were
analyzed to assess the lipid oxidation as affected by cooking in traditional
wood-fired ovens. Peroxide value significantly increased
in all vegetable oils, particularly in sunflower oil. EVOO polyphenols
decreased about 30% their initial level, particularly simple
phenolics. Total individual phenolic compounds decreased from
254.6 to 172.0 mg/kg. Pizza cooking caused the development of
some neo-formation volatile compounds caused by lipid oxidation
and Maillard reaction. Some positive key odor compounds were
found in pizza cooked with EVOO, and the addition of tomato
sauce and EVOO caused a dramatic change in its volatile pattern.

In the spring of 2008, the College of Gastronomy at Kodolányi János University of Applied Sciences set out to conduct a survey about the clientele and the selection of food and drinks of hospitality venues in Hungary in the framework of a national research project. The research period was set to three years, during which we aimed to study the contemporary gastronomy and hospitality by tourist regions. From the consumer side, we were interested in the make-up of the clientele (Hungarians or foreigners), the nationality of the foreign guests, their average spending and their motivation behind choosing a certain place or meal. From the supplier side, we surveyed the style of meals, the frequency of menu changes; whether there are separate drink cards, wine cards or cocktail cards, as well as providing a brief description about the style of the interior and exterior design of the venues. By the end of the first year of the project, we managed to survey 681 out of 771 venues, due to the substantial contribution from both teachers and students.

Sous vide technique is a method of baking products in vacuum under
vacuum for a long time at low temperature. In the scope of the 'sous vide'
technique, which is a new cooking technique that the molecular gastronomy gives
to the world of gastronomy, the meat is cooked by using the fillet steak and the
meat texture is cooked for 2 - 4 - 6 hours at 63 ° - 65 ° - 71 ° of the tissue images
using scanning electron misroscopy (SEM) that is the basis of this study. It is
expected that these experiments, which will take place in the laboratory
environment, will reveal scientific evidence and shed light on the work to be done
from now on. The results of the analysis of tissue samples at different temperature
grades are presented using SEM, which produces three-dimensional images. The
changes in the products cooked at the reference temperature and time are examined
and evaluated with these images. Experimental studies about the sous vide method
in Turkey have proven to be inadequate and the importance of this study is that the
number of experimental studies related to this technique, which is widely used all
over the world, is low and inadequate. This study was carried out in Gazi
University Molecular Gastronomy kitchen.

“Oltre il Gusto/Beyond the taste" is a retrospective study stemming from the findings of the Into the Food project. Over the course of 2015, the designers behind this project embarked on a journey in the universe of fine food aimed at analyzing, understanding and finding new and original ways to innovate high gastronomy thanks to food and eating design.

The application of nonthermal dielectric barrier discharge (DBD) plasma for altering the hydrophilicity or hydrophobicity
of polymer surfaces is well known. In this work, we demonstrate the potential of DBD plasma in enhancing
the surface hydrophobicity of freshly baked biscuits, evident from the increased spread area of
vegetable oil. The electrical and optical characteristics of the DBD plasma source have also been described. The
spread area of individual oil drops has been measured using a digital image analysis technique. An exponential
order of increase in the spread area has been observed at 80 kV with respect to treatment time, following DBD
treatment. The findings reported in thiswork have applications in the industrial preparation of biscuit and cracker
variants, where post-baking oil spray is desired. The effect of plasma treatments on the chemical constituents
of biscuit requires further investigation.
Industrial relevance: There is a substantive evidence for the need of an alternate process which allows retaining
functionality of sprayed oil in biscuits, with less oil or fat and increased spread. A novel process based on barrier
discharge atmospheric pressure nonthermal plasma for enhancement of oil spreadability on dry, snack food
products is developed. For a given volume of oil, up to 50% more spreading of oil can be achievedwithin fewseconds
of the process as compared to currently used methods. The plasma source can be easily integrated into a
continuous biscuit and cracker production or finishing line.

ABSTRACT Egg yolk stabilized butter sauces, such as hollandaise sauce, are classics in the French cuisine and adopted all over the world. They can be made using a number of different procedures. This study was done to determine how common butter sauce preparation methods influence perceptional parameters such as texture, mouthfeel and flavor. The goal was to evaluate the effects of the various preparation methods in order to gain control of the process and obtain the desired sauce properties. Five model sauces, prepared with the same amounts of ingredients, but with different procedures, were produced and analyzed. Sauce preparation methods differed regarding the amount of mechanical treatment, order of addition of ingredients, ingredient temperatures and states reached during production. The five model sauces were analyzed by particle size distribution, water and airiness measurements, microscopy, color measurement, descriptive sensory analysis and analysis of volatiles. Results demonstrated large differences between the explored types of hollandaise sauce, with texture and mouthfeel properties varying significantly with different preparation techniques. This study also included feedback from experienced chefs regarding their habits related to hollandaise sauce preparation.

ABSTRACT:  Although onion bulb tissues, either raw or thermally processed, are widely used as culinary ingredients in homes, in restaurants, and in the food industry, especially for sauces, little is known about the chemical constituents released from such systems. To get a straightforward and fast analysis of sugars released from onion dice soaked in model aqueous solutions, quantitative nuclear magnetic resonance (qNMR) spectroscopy was applied, and the effect of a preliminary thermal processing in oil was investigated. Soaking of raw or fried onion bulb dice at room temperature was followed for 11 d as a model of long-term storage. For the Armstrong cultivar, the extracted dry matter (in milligrams per gram of fresh weight) as well as the content in 3 sugars (glucose, fructose, and sucrose) increased up to a maximum after about 48 h of soaking. Frying induces no measurable new water-soluble compounds. However, extraction kinetics are different (about 3 times faster with frying). Using additional microscopic studies, a possible extraction mechanism is proposed: compounds from sap—including sugars—would diffuse through conductive tissue channels.

Öz Günümüzde gastronomi kavramını bilim ve sanat odağında evrensel perspektiften incelemeyi benimsemiş olan bilim insanları, geliştirdikleri modernist yaklaşımlarla, mutfak bilimi ve sanatının geleceğine verilecek yeni yönleri tasarlamakta; kavramı sadece geleneksel açıdan yorumlayıp turizm pazarında konumlandırmaya çalışan bilim insanları ise verilen yeni yönler doğrultusunda oluşturulmuş popüler gastronomi akımlarının takipçisi kalarak çalışmalarına devam edebilmektedir. Türkiye'de de gastronomi çalışmalarının ağırlıklı olarak geleneksel niteliklere yönelik hazırlandığı görülmektedir. Bu bağlamda, bu çalışma; ilk olarak bir evrensel gastronomik perspektif oluşturmayı; ikinci olarak, seçkisiz yöntemle belirlenen bir modernist mutfak çalışmasını ve ilgili yayınları doküman analizi yöntemiyle gastronomik perspektiften inceleyerek bir modernist mutfak anlayışını yorumlamayı ve alanyazında nasıl yorumlandığını tespit etmeyi ve bu sayede yeni bilginin nasıl oluşturulduğunu anlamlandırmayı amaçlamaktadır. Elde edilen ilk sonuç, gastronomik evrensel perspektifin disiplinler arası yaklaşımla oluşturulması gerektiğidir. Diğer sonuç ise gastronominin teorik ve pratik alanlarında eşzamanlı, bilim ve sanat odağında gerçekleştirilen modernist çalışmaların sadece turistik finansal değil uzun vadede politik güç sağlayan kazanımlar da yaratabileceğine yöneliktir. ABSTRACT Nowadays, a large number of scientists from different countries are trying to give their gastronomic knowledge a scientific structure or incorporate it into the tourism market. While those who have already adopted a scientific and artistic approach in their inquiry of gastronomy, for the notion of gastronomy keep on developing new approaches to culinary science and culinary arts from a modernist perspective, the others who put their knowledge and experience related to traditional values of gastronomy in the field to the service of commercial interests could only remain as followers of popular gastronomy trends. In Turkey, gastronomic studies are generally conduct with traditional methods and about traditional values of gastronomy. In this context, as a theoretical study based on close textual analysis of the scholarly literature concerning a random samplying study, this study aims at first, carving out a gastronomic perspective, second, analyse the study and other studies related to the study in order to interpret what does the modernist approach and the creating new knowledge mean. The first distinct result is stressing the necessity of redefining gastronomic perspective from a more holistic, interdisciplinary approach. Second outcome is that in both of theoretical and applied study areas of gastronomy, the modernist approaches which are developed with scientific and artistic methods can have not only touristic monetary gainings but also political power in the field, in time.

ABSTRACT Noting that Denmark is traditionally an agricultural country and that a large part of the gross national product derives from the export of meat and processed food products, this article points out the paradox that only during the last decade has some Danish food-related research been genuinely driven by gastronomy and gastronomic innovation, and only recently have research activities and academic educational programs that include aspects of molecular gastronomy and other culinary sciences been initiated. At the same time, Denmark has placed itself on the international map due to innovative chefs winning top international awards and celebrated positions on lists of the best restaurants worldwide. Moreover, the New Nordic Cuisine movement has released novel driving forces and instigated new types of collaborations between chefs and scientists. Danish scientists of different orientations are being stimulated by the empirical world of gastronomy and cooking and are maturing molecular gastronomy as a science, and others have become proliferate writers and communicators of gastronomically inspired science; for example, within gastrophysics.
