Traditional sausages—smoked, fermented or dried—are meat products that are part of the traditional daily diet in rural Portugal, and also highly valued in major cities with an increasing demand. These ethnic meat products are manufactured mainly by small-scale industries or artisanal producers according to and/or inspired by traditional processes. They are present in a wide variety of types, many recognized for their quality (38 certified products). Presently, cure technologies used are important for the potential they represent in transformation and diversification. Additionally, they add flavors and colors to meat that are much appreciated, surpassing meat preservation proposes. A review on the types and manufacturing technological aspects associated to Portuguese traditional sausages (PTS) is provided in this article. Additionally, nutritional composition of the products is presented. Future developments foreseen in the field, in the light of current knowledge and market trends, are finally addressed

The connection between tourism and nature justifies the environmental concerns from tourism agents, namely global hotel chains. This paper explores the differences between smaller hotel chains and their larger global counterparts regarding environmentally sustainable practices. The research approach is qualitative, based on the analysis of 40 company websites and in-depth interviews with 18 entrepreneurs and executives. Results suggest that environmental issues are, for most companies, not a response to societal challenges (‘doing the right thing’), but a response to owners’ concerns (‘doing things right’). Hotel chains develop environmental sustainability practices, mainly for cost-reduction purposes, accommodating the owners’ demands for efficiency. Notwithstanding, there are differences according to the chain’s size. Smaller companies are less prone to adopt environmental practices and to invest in communicating them than global chains. Concerning sustainability in the hotel industry, most studies focus on specific topics and discussions. A more holistic approach to sustainability to establish a deeper understanding of sustainable business decisions in the hotel sector is scarce in the literature. This paper addresses this gap by exploring the strategic reasons behind the sustainable practices of hotel companies, namely smaller ones. Managerial implications of the results are also derived in this paper.

It is widely recognized that smelling food results in a mouth-watering feeling and influences appetite. However, besides changes in volume, little is known about the effects that food odours have on the composition of saliva. The aim of the present study was to access the effects that smelling bread has on saliva proteome and to compare such effects with those of chewing and ingesting it. Besides a significant increase in saliva flow rate, together with a decrease in total protein concentration, bread odour induced changes in the proportion of different salivary proteins. The expression levels of two spots of cystatins and two spots of amylase increased due to olfactory stimulation, similar to what happened with bread mastication, suggesting that odour can allow anticipation of the type of food eaten and consequently the physiological oral changes necessary to that ingestion. An interesting finding was that bread odour increased the expression levels of several protein spots of immunoglobulin chains, which were decreased by both bread or rice mastication. This may be of clinical relevance since food olfactory stimulation of salivary immunoglobulins can be used to potentiate the oral immune function of saliva. Moreover, the effects of bread odour in the levels of salivary proteins, previously observed to be involved in oral food processing led to the hypothesis of an influence of this odour in the sensory perception of foods further ingested. Further studies are needed to elucidate this point, as well as whether the changes observed for bread odour are specific, or if different food odours lead to similar salivary proteome responses.

Excessive free-sugar intake has become highly prevalent in numerous countries, and Portugal is not the exception. One product category that contributes to the daily intake of free sugars is breakfast cereals. In the current work, we identified 289 exemplars from two major retailers in Portugal and collected information on their nutritional profile (e.g., sugar, salt, fiber per 100 g), price, packaging features, type of food claims present (e.g., statements about the composition, sensory features, the origin of the product), and ingredients list. Overall, the sugar content of breakfast cereals was high (Mean = 19.9 g), and less than 10% of the products complied with the current national guidelines (i.e., 5 g of sugar per 100 g of product). Sugar (or other sugar sources) was listed in the top three ingredients for over 85% of the products. On average, each product included about four claims (Mean = 3.9), and sugar content was lower when the claims were related to the product composition. Critically, the sugar content was particularly high for children-oriented products (Mean = 26.4 g). Correlation analysis showed that breakfast cereals with higher sugar content also were cheaper and had lower quantities of fiber, proteins, and salt. Our findings suggest the need to implement strategies to reduce sugar in this product category (e.g., incentivize manufacturers to reformulate products). Also, our results may inform strategies aimed at promoting consumers’ awareness about the sugar content in breakfast cereals and other processed foods, facilitating healthier decision-making.

Considering the importance of the food environments for health promotion, and the lack of simple, easy to use, low-cost measures of the quality of meals, the authors developed a qualitative menu index (KIMEHS—Kids’ Menu Healthy Score), tailored to children’s menu evaluation. Development of the tool was based on the Mediterranean food pattern. It includes 18 components, divided into seven main groups that reflect key aspects of menu quality, including protein source, side dishes, vegetables, dessert and beverages, and also allergens and nutritional information. The index was analysed for content and construct validity, as well as inter-rater reliability, and was applied to a sample of menus from restaurants in shopping centres in the Lisbon region. Possible index point ranges from −17 to 17, with a higher score indicating greater compliance with the recommendations. A value of 5.5 is obtained if all KIMEHS items are available, considering healthy and non-healthy options. The inter-rater reliability was assessed and values above 0.80 were obtained for Alpha Cronbach, as well as agreement % rate >75%. Agreement percentage is above 75% for all the components. Evaluated restaurants scored from −14 to 7, with an average KIMEHS of −6.15. Only four restaurants scored positive values, ranging from 0.25 to 7. KIMEHS was considered to be an adequate index to evaluate children’s menus, from the menu information displayed on restaurant websites and/or on restaurant displays or table menus. It is a simple, low-cost tool that may be used as a reference for health professionals as an objective measure to evaluate the food environment. Stakeholders could also be involved in their own assessment to help educate consumers about healthy food choices, strengthening the efforts to promote an adequate food pattern and health, contributing to the fight against obesity.
