The aim of the present study was to reveal if sensory properties of smoked food could be considered as decisive in the determination of one product’s preference over another. In addition to this, this work tries to clarify whether the flavour obtained in commercial smoked products was noticed and clearly recognized. This study consisted of two parts; first, a preference testing without physical products (recalled preference) presented using a nine‐point hedonic scale, and second, a difference testing with selected products using the triangular test. Consumers showed a preference for non‐smoked products, particularly for cheese, sausages and chips. The first preference dimension of the internal preference mapping (MDPREF) analysis accounted for 74.6 per cent of total variation indicating overall agreement about likings relating these products, with cheese being the most acceptable overall. Analyzing triangular test results it may be concluded that other factors but sensory ones must be defining consumer representations of smoked food, without a correspondence with its real organoleptic properties.

The purpose of this paper is the physico-chemical, microbiological, colorimetric, sensorial characterization of choris, a traditional smoked pork sausage produced in the state of Goa (India), including its storage stability (0–180 days) at room temperature, aiming at the geographical indication certification and entrepreneurship prospects.

A total of 48 samples of “choris” were collected from 24 villages of Goa and were analyzed at different intervals (0–180 days) for physico-chemical, proximate, microbiological, colorimetric and sensory attributes during the storage at room temperature.

The mean pH of 4.45 and water activity (a_w) of 0.78 were recorded. The pH, tyrosine value, fat percentage and free fatty acid content registered a significant increase, whereas moisture content, a_w and moisture–protein ratio reduced as storage progresses. The colorimetric values lightness (L*), hue angle (H*) and redness index values reduced significantly during storage. The mean total viable count, yeast and mold, and lactic acid bacteria count were found to proliferate significantly as storage advanced. Nevertheless, the hedonic scores not reaching an unacceptable level (= 4) at the end of the storage period.

In accordance with the various parameters adopted during the study, choris could be characterized as “naturally fermented dry smoked” sausages, which were shelf-stable at room temperature for 180 days. The product characterization of choris is essential to guarantee the genuineness, safety and consumer's acceptability. This study will also rebound in an augmented uniformity of the product, which will favor the geographical indication certification and the entrepreneurship prospects of this traditional product.

The purpose of this paper is to assess food safety knowledge, choice behavior and health hazard concerns of ethnic Goan pork sausage consumers through various consumer food safety indices and also to evaluate socio-demographic influences on various consumer food safety indices.

Primary data in the form of 210 questionnaire responses were collected from Goan pork sausage consumers. Based on the responses, seven various consumer food safety indices were derived. The cumulative score of all the indices were normalized (0–1). The association between socio-demographic variables and consumer indices were evaluated using linear regression analysis, Pearson's correlation matrix, principal component analysis (PCA) and correspondence analysis (CA).

The results of the analysis indicate that the consumption of Goan pork sausages is most prevalent amongst younger people with high education having higher income. A majority of consumers have high score for the four consumer indices. The results of correlation analysis, regression analysis, PCA and CA revealed a significant association of consumer indices with socio-demographic variables.

The results of this study will provide a way forward for the evaluation of existing overall food safety concerns in the target population and in the future would be used for the promotion of good handling practices and health of Goan pork sausage consumers.

The purpose of this paper is to model the relationship between 11 frankfurter physical properties and their sensory scores to classify a release of frankfurter production batches to the market.

Data from 209 frankfurter batches were collected. Market batch release classifications were based on 11 physical properties via predictive and direct classification models. The predictive models under study included a regression, backpropagation neural network (BPN) and radial basis function neural network (RBFN) whereas the direct classification models were logistic regression, BPN and RBFN. Model performance was evaluated via correct classification rate.

The 11-7-4 RBFN predictive model proved superior with a 90 percent correct classification rate and 0 percent producer risk while the 11-5-1 RBFN, as a classification model, outperformed with the same level of accuracy, 90 and 0 percent, respectively. Producers prefer the less time-consuming direct classifiers for evaluation. Furthermore, the 11-5-1 RBFN direct classifier revealed that color measurement greatly influenced frankfurter batch release. Increases in redness, yellowness and brownness increased batch release probability.

This research attempts to establish a novel production batch release model for sausage manufacturing. Key factors can then be optimized for improving batch release probability for implementation throughout the sausage industry.

The season of mass holiday treks for the multitude is upon us. Since the new year, the newspapers and magazines have carried pages of advertisements and travelogues and each year the holiday horizon is pushed farther and farther away; now it includes Bulgaria, Rumania, remote islands, countries beyond the Iron Curtain and even China. Tourism has become big business. In the U.K., with a million or more visitors, it is considered a major industry. But what of Italy with eight million visitors, Spain running her very close, France with a mere two millions, Switzerland, Austria and other countries in between? All these countries may be geared to meet big invasions of foreign people during the tourist season, but understandably there are inevitable health risks and the most important of these are undoubtedly water‐ and food‐borne infections. Dietary disturbances due to the change of food and drink, especially of wine, by people who are unaccustomed to it, are of a transitory nature, and remedied by simple measures which include abstinence from rich and indigestible foods.

Some months ago a national organisation established to keep a watchful eye on the Nation's diet expressed concern over the eating trends of people in what to them appeared to be developing inbalances of necessary nutrient factors and the inadeuacy not so much of calories and energy values but in the nature and quality of main food factors. It was recommended that the national diet should be improved, but the authorities pointed to the National Food Survey results to show that the diet was not deficient; that the average daily intake of protein, vitamins, minerals and overall energy requirements were satisfied; all of which is true for the not‐too‐generous levels set. Even the pensioner households included in the Survey sample appear well‐fed. What causes concern is the year‐by‐year decrease in staple foods consumed—milk, red meat, bread, fresh vegetables—and the heavy reliance on refined, processed foods. In its annual reports on NFS reviews, the BFJ has almost monotonously referred to this downward trend. Individual NFS Reports do not reveal any serious deficiencies, as yet, but in the trend over the years—and herein lies the real value of the Survey and its data—few if any of the changes have been for the better; movements in food groups have tended to be downwards. If these trends continue, the time must surely come when there will be real deficiencies; that substitution within a food group cannot make good essential foods severely rationed by high prices.

Few regret the passing of an old year, with its darkening days and cold nights, its message fading as the voice weakens. A new year always looks more attractive with hopes of better things to come, but an occasional look back over one's shoulder, as it were, is seldom completely without profit, for experience can sometimes be more potent than hope. 1968 seemed to have more than its share of uncertainties, tragedies and disasters, in this country and in the world at large. An unsure economic state, to say nothing of monetary confusion, was reflected in every field of industry and public administration, but in the field of food quality and purity control, steady progress towards a comprehensive system of food standards, of hygiene and of food additive control was maintained. In fact, the year may be seen as not an entirely unfruitful one, with one or two events which may well prove to be landmarks.

This chapter examines the financial performance efficiency of the restaurant sector in Croatian counties over the period 2013–2017. Today's tourists are ambitious explorers who travel in order to find and explore new experiences and motives for travelling as long as there are interesting things, activities and offers which correspond to their preferences. Among the many motives that today's tourist decides to travel, gastronomic tourism certainty plays an important role. The observation period began in 2013, since that was the year when Croatia acceded to the European Union and joined all the other prominent European food destinations. In order to evaluate the financial performance efficiency, the methodology of the data envelopment analysis (DEA) was applied separately to the data processing of each year. The results of the Charnes–Cooper–Rhodes model showed that only four counties (Lika-Senj, Zadar, Istria and Dubrovnik-Neretva) achieved continuous efficiency over the whole observed period. In 2013 the results of scale efficiency showed that 10 counties (Krapina-Zagorje, Karlovac, Bjelovar-Bilogora, Lika-Senj, Požega-Slavonia, Zadar, Šibenik-Knin, Split-Dalmatia, Istria and Dubrovnik-Neretva) achieved a score of 1, and in later years there was a decrease. One of the main obstacles of the existing inefficiencies in the entire restaurant sector in Croatian counties is certainly changeable tax legislation and lack of employees in the restaurant sector.
