New generations are adopting eating styles associated with healthy and sensorially acceptable routines, focusing on discovering new sensations, which has allowed the bakery line to include sourdough products. The use of sourdough has regained importance in the food industry, as it is an ideal habitat for the growth of yeast and bacteria, conferring special sensory characteristics. The development of this research work provides a solution to the current need, focusing on including sourdough with different fermentation times in the elaboration of covered bread to modify the sensory characteristics. Four formulations of tapado bread with sourdough inclusion were proposed. In the sensory analysis, the sample with sourdough after 7 days of fermentation stood out, which presented the best values of flavor, color, and acceptability. The flour mixtures were analyzed by mixing, and the bread made was evaluated by texture. The texture analysis of the bread samples showed favorable values of hardness, elasticity and chewiness of the sample with inclusion of sourdough after 7 days of fermentation. Finally, in mixography, significant differences were observed in C1 (water absorption index), in contrast to C2 (protein quality), C3 (gelatinization), C4 (amylase index), and C5 (starch retrogradation).

Malnutrition represents a problem of great importance within the country, affecting the population in general. This issue poses a serious public health risk in Ecuador, leading the country to allocate significant resources to treat diet-related diseases instead of prioritizing preventive health measures. To address this situation, a research study focused on analyzing the composition of the dietary intake in two groups of households whose economic activity is agriculture, located in the main regions of agricultural production in the country. Comparative data was obtained through surveys and interviews based on the 24-hour dietary recall method. The aim was to determine the level of food access through the Household Dietary Diversity Score (HDDS) and the consumption of macronutrients in the diet. Additionally, data on sociodemographic characteristics, living conditions, and food acquisition methods were collected to evaluate their influence on eating habits. The research findings revealed that, overall, households in both groups demonstrated a high level of dietary diversity (HDDS). However, significant differences were observed in the consumption of macronutrients, with the consumption of fats and carbohydrates being considerably higher compared to the Sierra group in both sample groups. This disparity is directly correlated to the geographic location of the households and their patterns of macronutrient consumption.

The school feeding program has contributed to reduce the gap in access to education and in turn to improve the nutritional status of children, the school breakfast is considered a food supplement, which provides energy and vitality for adequate cognitive functioning during the learning process of schoolchildren. The sensory evaluation of drinks and cookies was carried out, comparing them with products that present similar characteristics. For the statistical analysis of the data, ANOVA and T Test were obtained using the IBM SPSS statistical program. From the test applied to 205 children from public schools, Teniente Hugo Ortiz Basic Education School and Francisco Flor Educational Unit (Blocks 1 and 2) of the Huachi Chico parish and the sensory profile of the school breakfast products of 15 semi-trained tasters, allowed to determine the acceptability of the different school breakfast products. According to the results obtained, they indicate that the school breakfast products are not to the taste of the children of the public schools belonging to the Huachi Chico parish, in relation to the sensory profile carried out, it was evidenced that they follow the same line of acceptance obtained by part of the public schools.

The COVID-19 pandemic has changed the way of life of human beings and even eating habits due to confinement. As such, the objective of this study is to identify the relationship between eating habits and the socioeconomic level of adult men and women in the city of Ambato. As a methodological part, a cross-sectional design is proposed, by means of online data collection, using a semi-structured questionnaire. Eating habits are determined by means of the Consumption Frequency Questionnaire and the use of the Healthy Eating Index (IAS). Socioeconomic status is determined in terms of economic income. In addition, information about perceptions and attitudes towards confinement is requested. The results show that according to the IAS the population falls into the following categories: 10.9 percent with healthy eating, 69.3 percent with eating in need of change and 19.7 percent with unhealthy eating. The population indicates that their economic income ranges between 121 USD and 400 USD and they designate between 50 USD and 100 USD per month for food expenses. The female gender registers an increase in body weight, more sedentary time, reduction in physical activity time and unhealthy eating habits. There was a significant association between eating habits and socioeconomic level with p equal to 0.0001. The close relationship between dietary habits and purchasing power generates that the population analyzed is restricted to the adoption of healthy eating patterns.

In 2018, 1 out of every 9 people in the world were hungry, 42.5 million in Latin America and the Caribbean. The problems associated with eating habits and malnutrition are alarming in the region. In 2019, 262 million adults were at some level overweight and obese. 4.9 million and 4 million children are stunted and overweight, respectively. Approximately 600,000 adults die each year from causes related to poor nutrition (FAO et al., 2019). In Ecuador, the reality is similar, with the continued increase in overweight and obesity in all ages, in addition to the prevalence of stunting and micronutrient deficiencies. In addition to this problem, the economic impact of malnutrition, which in 2014 reached USD 4,300 million a year, is added (MSP, 2018). Using surveys based on the 24-hour reminder method, a study was carried out in the population of the urban area of Ambato to understand their eating habits and their relationship to levels of food insecurity. The study found that most are at the level of mild insecurity, but their perception of food security does not necessarily place them in the group of good eating habits. That is, despite having the purchasing power to buy food and eat five meals a day, balanced and nutritious diet is not a priority in Ambato families.

The agroecological production model allows the use of ancestral techniques to improve agricultural production processes. Doing this it influences different aspects such as social, cultural, economic and even health of the people. The foods derived from this activity are made without the application of agrochemicals that can be harmful to the body, which makes them a very attractive product to improve the quality of life, change traditional production models and take care of the environment. The analysis of this research was carried out by applying surveys aimed at producers and consumers in order to determine the socioeconomic factors that are related to the demand for agroecological foods, identify aspects that influence consumption and the difference in the preference of food that exists in both groups evaluated. It was determined that the main socioeconomic factor that influences the consumption of agroecological products is the level of education since people with a bachelor's degree and third level consume a higher percentage of this type of food. The eating habits of producers and consumers differ from each other, influencing the presence of diseases. Overweight is the disease mainly suffered by producers, while in consumers it is hypertension. The results show that they should use better promotion techniques for these types of products to encourage healthy eating, strengthen the local economy and take care of the environment.

Currently, factors have modified our eating habits such as short time spent at home, multitasking, fast food advertisements, availability, and accessibility of food, which cause the loss of perspective of a proper diet. The objective of the research was to analyze comparatively the food diet in a small group of families in the urban and rural areas of Ambato and Píllaro towns. The report about the food diets component has obtained by applying a Consumption Frequency Questionnaire to the urban area of Ambato and a form open and closed-ended questions to the rural area of Píllaro. The findings achieved to show the existence of several ranges of foods, especially from fruits, greens, and vegetables. The frequency of potatoes consumption in both urban and rural areas is high. The consumption of milk in the rural area is more frequent, as well as the guinea pig meat, on the other hand, the three processed products such as rice, sugar, and bread are consumed 4 or more times per week. Farmer´s knowledge of agroecology reaches 71 percent and while 75 percent of the people in the urban zone claim to consume organic products. Finally, the Healthy Eating Index shows that the urban population needs changes in their diet, having reached a score of 45.5, while the score obtained by the farmers is 79, 5 that it seems like a healthy diet.

The need for healthy and nutritious food production that enhances food sovereignty has been a concern of many governments. Therefore, this work was carried out with the purpose of identifying sustainable food production models in Píllaro County as a contribution to food sovereignty. To this end, a survey was applied with agro-ecological parameters, where variables such as: type of production (agricultural and livestock), size of land (approximate area per farmer), quantity produced (volume of production for each item), and crop diversification (number of crops used per plot of land) were studied. Through this method, an extensive list of agricultural species cultivated by the population analyzed was found. Through the analysis of results, three agro-food models with sustainable production were identified. These models are based on crop diversification and have been established as high, medium and low diversification agro-food models. Similarly, Food Sovereignty was evaluated in order to ascertain the contribution of the models identified. For this evaluation, indicators of Food Sovereignty were used, taking into account five parameters: access to resources, production, processing and marketing models, food consumption and the right to food, and agrarian policies. These results demonstrate the influence of agrifood models on Food Sovereignty in Píllaro canton and prove that crop diversification allows for the availability of varied foods.

The present investigation determined the current consumption of organic / agro ecological fresh food of the families of the province of Tungurahua, in three market segments according to the monthly economic income, through the application of a validated survey, and the analysis of the information obtained. It is estimated that 79% of the families consume organic/agro ecological food in the province, with families with an average income level having the highest consumption, while families with a high income level are the least consuming . In addition, among the variables of the survey, a main component analysis was carried out using the SPSS version 20 program, which allowed the identification of marketing, preferences and education aspects, in 54% of the family consumption of organic foods in the province. Finally, through Gretl software version 1.9.92, a logistic econometric model was proposed, which explains the consumption of fresh organic/agro ecological foods, based on the main components obtained and the family economic income variable. The supply of fresh organic/agro ecological foods was determined through interviews with expert informants and observations made by the researcher. It is concluded that the supply of this type of food in the province, could cover its demand up to 54%.
