GASTRONOMIC TOURISM (CULINARY TOURISM) AND TRADITIONAL FOODS: MARDIN
(4 th International Conference on Engineerg and Natural Science, 2-6 May 2018, Abstract Book, 2018) Çelikel, Aslı; Akın, Mutlu Buket; Gürbüz, Semra; Toprak, Lokman
Gastronomic tourism can be described as the trips made by tourists to experience local food and beverages. Because as it is thought that approximately one in four of the tourism expenses devote to food and beverage spending, gastronomic tourism is an important source of income for the people of the region. At this point, gastronomic tourism plays an important role in increasing the demand for some tourism attraction centers and in creating new attraction centers. In recent years, geographical indications in our country for traditional food, which is the most important compound of gastronomic tourism, have increased. Geographical indications encourage traditional production and the preservation of the tastes of local food and beverage. Mardin, which is one of the important touristic places of our country with its rich cultural structure and historical places, is among the provinces that has the priority in terms of gastronomic tourism according to the 2014 TUSAD report. Although there are more than 40 regional dishes in Mardin, where many different religions and people live together, only 5 of them have geographical indications. These are Mardin rib fills, Mardin kibe, Mardin sembusek, Mardin ikbebet and Mardin imlebes (almond candy). At this point, the introduction of other regional tastes unique to Mardin will contribute to the expansion of traditional food production and the improvement of gastronomy tourism. In this study, traditional foods and beverages in Mardin province were investigated.
DETERMINATION OF VIABLE BACTERIAL COUNTS AND ACETALDEHYDE CONTENTS IN BIOYOGURT PRODUCED BY USING LACTOBACILLUS ACIDOPHILUS AND LACTOBACILLUS CASEI AT DIFFERENT INOCULUM RATES
(4 th International Conference on Engineerg and Natural Science, 2-6 May 2018, Abstract Book, 2018) Akın, Musa Serdar; Göncü, Büşra; Çelikel, Aslı; Eren Karahan, Leyla; Akın, Mutlu Buket
Due to their attributed health benefits, probiotic bacteria (such as L. acidophilus and/or Bifidobacteria) have been increasingly included in yogurts and fermented milks during the past three decades. The addition of probiotic bacteria is made not only because of certain claimed health-promoting effects in the intestinal tract but also because of the sensory aspects as well as the expanding variety of products that can be formulated with them. In this study, the effects of different inoculum rates of Lactobacillus acidophilus and Lactobacillus casei of using in the production of bio-yogurt on the viable bacterial counts and acetaldehyde contents were determined during storage.For this purpose, different inoculum rates (1%, 2% and 3%) of both probiotic bacteria were tested. So, suitable inoculum rate were detected for production of bio-yogurt, which has enough probiotic bacterial content for supplying desirable aromatic effect and also the therapeutic minimum (106-107 cfu g-1). In addition to, the effects of inulin (at a rate of 1%) were searched for encouraging of probiotic bacterial development and quality of bio-yogurt. According to the results, the effects of inoculum rate of probiotic bacteria, storage period and addition of inulin were significant on the physicochemical, microbilogolic and sensory properties of bio-yogurt (p<0.01).
THE EFFECTS OF ENCAPSULATED PROTEASE AND LIPASE INTO GELLAN ON THE TEXTURAL AND ORGANOLEPTICAL PROPERTIES OF KASHAR CHEESE
(4 th International Conference on Engineerg and Natural Science, 2-6 May 2018, Abstract Book, 2018) Akın, Mutlu Buket; Göncü, Büşra; Çelikel, Aslı; Akın, Musa Serdar
Kashar cheese is the most commonly produced and consumed cheese in Turkey, the Balkan Peninsula and the Mediterranean region after white cheese. The main problem in manufacturing Kashar cheese is the long maturation period, which increases the cost of handling significantly. Several attempts have been made to reduce the ripening period by the addition of individual and mixed lipase, protease and β-galactosidase enzymes, some of which have been reported to halve the normal maturation period of cheese. The addition of free lipase or protease has resulted in premature attack leading to excessive lipolysis, proteolysis and texture and flavour defects. The use of microencapsulated enzymes has been proposed to improve these drawbacks. In tis study, lipase, protease and the mixture of them were encapsulated in gellan and added to Kashar cheese milk to accelerate cheese ripening. The effect of encapsulated enzymes on the textural and organoleptical properties of the cheese was investigated during 180 days storage. According to the result, the best cheeses were obtained with encapsulated protease. So usage of encapsulated protease into gellan for Kashar cheese production could be recommend.
COMPOSITE EDIBLE FILMS AND THEIR FEATURES
(4 th International Conference on Engineerg and Natural Science, 2-6 May 2018, Abstract Book, 2018) Çelikel, Aslı; Akın, Mutlu Buket; Akın, Musa Serdar; Göncü, Büşra; Eren Karahan, Leyla
Edible films are materials that are not synthetic and can be consumed with food, coated with various methods on the surface of the product in order to protect the food, extend the shelf life and provide functional properties. Composition of edible films consists of a combination of one or more substances such as carbohydrate, fat, protein and plasticizer. Nutritional values of foods are supported with edible film coating, especially with the films made of proteins. The antimicrobial and antioxidant substances added to edible films avoid the growth of microorganisms on the food surface and prolong the shelflife of the foods. It is desired that edible films should be as odorless, tasteless, colorless, transparent, clear as possible, durable and flexible as well as in compliance with the foodstuff in order to avoid the adverse effects during consumption. In addition, edible films are able to meet the different functional needs (moisture barrier, gas barrier, water and lipid solubility, color and appearance, mechanical properties, etc.) of the product to which they are applied. In recent years, the use of edible composite films containing more than one component has become widespread, in contrast to the onecomponent edible films desired for edible film production. In this study, researches on edible composite films and their properties have been reviewed.
