- HostLab: gastronomy innovation, experiences and sustainabilityPublication . Gonçalves, Alexandra; Ramos, Celia; Martins, Ana Isabel; Serra, Manuel; Rassal, C.; Monteiro, Carlos; Martins, Paula; Quintas, Célia; Ratao, Isabel; Nunes, Patrícia; Silva, Beatriz; Viegas, CarinaInnovating through traditional products and resources is the main aim of HoST Lab Project located at the School of Management, Hospitality and Tourism of the University of the Algarve. A new lab and new multidisciplinary way of working, that which to be a reference for research and development applied to Culinary Tourism and Eno-gastronomic experiences associated with the Mediterranean Diet (MD). A very enriching proposal was built to study the determinants of experience and the atmosphere of places, promoting sensory evaluation with tourists and stakeholders, of new products and services (based on local resources and products, such as cereals, olive trees, vines, and other foods), enhancing the qualification and diversification of the Algarve as a sustainable tourist destination. We hope that this new partnerships and stakeholders involved will help sharing this common vision, the knowledge delivered and continue promoting innovation around the Mediterranean Diet.
- Effect of chloride salts on the sensory and nutritional properties of cracked table olives of the Macanilha Algarvia cultivarPublication . Saúde, Cíntia; Barros, Tânia; Mateus, Tania; Quintas, Célia; Pires-Cabral, PaulaThe effect of sodium chloride replacement with potassium chloride and/or calcium chloride in the fermentation brines on the physicochemical, organoleptic and nutritional profiles of cracked table olives was studied using no more than 8% salt. Although all brines led to vigorous fermentation with the desired characteristics of acidity and saltiness, the sensory panel rated the olives fermented in 8%NaCl and 4%NaCl + 4%KCl as the best, in terms of flavor and overall attributes. The olives fermented in the other brines (4%NaCl + 4%CaCl2, 4%KCl + 4%CaCl2 and 2.7%NaCl + 2.7%KCl + 2.7%CaCl2) were not acceptable. Olives fermented in 4%NaCl + 4%KCl had lower fat, carbohydrates, dietary fiber, calories and similar amounts of phenolic compounds and Ca as the 8%NaCl treatment. In addition, the former had increased K (672%) and reduced Na (19%), making them more nutritionally acceptable. This alteration might be beneficial and allow the olive market to reach new customers or present current customers with a potentially healthier product.
- Mediterranean Diet gastronomic experiences using olive oil and goat cheesePublication . Ratao, Isabel; Nunes Cabrita, Patrícia; Silva, Beatriz; Viegas, Carina; Dionísio Serra, Manuel António; Quintas, CéliaThe present study aims to develop three food formulations, spreadable olive oil, goat cream cheese, and a cold dessert made of carob and goat cheese, using local elements of the Mediterranean diet (MD), namely, olive oil, fresh goat cheese, and carob derivatives in addition to hydrocolloids. The final products, with the best spread- ability, texture and consistency, were obtained using: a) methylcellulose 6% (w/v) for the spreadable olive oil; b) Locust Bean Gum (LBG) (0.5% w/w) for goat cream cheese; and c) Goat cream cheese (43.4%), carob flour (8.7%), glucose syrup (26.1%), olive oil (14.6%), powdered goat milk (3.8%), chia seeds (0.5%), LBG (0.7%), and cinnamon for the cold dessert. Subsequently, foods were refrigerated until evaluated by a consumer panel of 101 untrained tasters aged between 15 and 49 years. All the attributes were assessed on a scale from 1 to 5. The products were well accepted by the tasters with no significant differences registered among the different age groups regarding the food attributes, except for the sweetness of the dessert. The goat cream cheese obtained the highest acceptability (4.09 f 1.16-3.88 f 0.86) and creaminess (4.22 f 0.80-4.33 f 0.65) among the youngest consumers (<30 years), while the acceptability of spreadable olive oil was evaluated with values of 3.24 f 1.33-3.17 f 1.14 by the same age group, indicating the need to add seasonings, as salt substitutes, to improve the attributes flavour and aroma. The results highlight the potential of the three formulations to expand the range of food products and processing strategies in the hospitality, catering, and food industry, as well as to provide alternative foods associated with the MD food pattern.
