This study aimed to develop an orange (Citrus sinensis) marmalade fortified with inulin. Several formulations were prepared by varying the amount of inulin, which was incorporated due to its nature as a soluble fiber with prebiotic effects, known for its digestive benefits and its ability to improve product texture. Additionally, low methoxyl pectin was used, as it has the ability to form gels in the presence of calcium ions, making it possible to prepare low-sugar products without compromising texture or consistency. To reduce the caloric content of the marmalade, stevia was also added. All samples were subjected to sensory evaluation by a panel of individuals who rated the flavor, color, aroma, texture, appearance, and overall acceptability. Based on these evaluations, the most accepted formulation was selected as the best option. This selected formulation was then analyzed to determine its physicochemical properties (such as pH, Brix degrees, acidity, color, viscosity, water activity, and moisture content), microbiological quality (presence of molds, yeasts, and pathogenic microorganisms), and nutritional composition (fiber and protein content). The results confirmed that the marmalade met current food safety and quality standards. A healthy and functional orange marmalade was successfully developed, characterized by good taste, low caloric content, food safety, and added nutritional value ideal for consumers seeking to maintain a healthy diet without giving up traditional products

The lack of functional formulations of wild berry-derived products hampers the exploitation of their beneficial bioactive compounds, especially those with antioxidant properties such as polyphenols. In this study, we sought to evaluate the antioxidant power of the microencapsulated passionflower extract (Passiflora mixta) by spray-drying and its use in the preparation of berry jam. Two important aspects were considered to obtain the polyphenolic compounds: extraction time (30, 60, and 90 minutes) and ethanol concentration (25, 50, and 75 percent), with optimal values being 30 minutes and a solvent content of 70 percent. The extract was subsequently microencapsulated by spray-drying with maltodextrin as the encapsulant, reaching inlet and outlet temperatures of 150 and 90 degrees Celsius, respectively. This process showed an efficiency of 85,74 percent, and the subsequent DPPH evaluation yielded an inhibition of 61,33 percent for the concentrated extract and 38,67 percent for the microencapsulated extract. Finally, a functional jam was formulated and subjected to sensory evaluation by a group of semi-trained tasters to determine the acceptability of the final product. In conclusion, this study was useful for the formulation of functional products that promote a healthy and balanced diet.

This research evaluates the effect of temperature on the flow parameters of jam made from Chinese cherry (Dovyalis abyssinica), an exotic fruit that is underutilized in Ecuador despite its high nutritional content, especially vitamin C and antioxidant compounds. The importance of the study lies in improving knowledge about the rheological behavior of this jam, contributing to the innovation of products derived from native fruits with potential. The methodology consisted of collecting and preparing the fruit in the form of a puree, followed by cooking it at 150 degrees Celsius for 13 minutes. The viscosity of the jam was evaluated using a rotational viscometer at different temperatures (10 to 60 degrees Celsius), and the experimental data were adjusted to mathematical models of non-Newtonian flow, such as Herschel-Bulkley and Casson. The results showed that temperature has a significant influence on the viscosity and rheological behavior of the product. At higher temperatures, viscosity decreases, which directly affects its texture. It is concluded that properly controlling the processing temperature is key to maintaining the desired physical properties in Chinese cherry jam, optimizing its sensory quality and market acceptance.

This research focuses on the development of a Good Manufacturing Practices (GMP) manual for the microenterprise ACPRA FOOD, which is dedicated to the production and distribution of jams and jellies. The implementation of this manual will enable the microenterprise to achieve GMP certification, ensuring the safety and quality of its products in accordance with the standards established by the National Agency for Regulation, Control, and Health Surveillance (ARCSA). An initial diagnostic of the microenterprise's situation was carried out using the checklist from ARCSA Resolution ARCSA-DE-2022-016-AKR, which determined a compliance rate of 60.2 percent, a non-compliance rate of 30.8 percent, and a 9.0 percent rate of not applicable. Standard Operating Procedures (SOPs) and Sanitation Standard Operating Procedures (SSOPs) were developed, aligned with the microenterprise's needs, to improve quality and ensure compliance with regulations. An action plan was proposed, including corrective measures based on the identified non-conformities, which require an estimated investment of US$ 5,560 and a one-year implementation period. Trainings on basic hygiene, quality control, and sanitation processes were conducted, and improvements to the plant layout in the production area were suggested. Upon completion of the work, a new checklist was performed, showing a compliance rate of 66.4 percent, achieved through the implementation of records and staff training.

In recent years, there has been a growing demand for products with a high nutritional level. This has driven the search for new processing technologies that allow preserving the properties of food. In this study, a new technology is analyzed to transform the Chinese plum tree, with the aim of maintaining its sensory characteristics; developing a jam with this fruit using an oil bath to simulate the processing temperature in an industrial plant at four temperatures: 120, 130, 140 and 150 degrees Celsius, to evaluate the rheological and sensory parameters of the jams. In addition, the proximal composition of the jam was evaluated with greater sensory acceptability. The sensory profile graph showed that the jam made at 150 degrees Celsius was selected as the best treatment. On the other hand, the jam at 120 degrees Celsius presented higher viscosity values; while the jam at 150 degrees Celsius presented lower values. All the jams required a threshold effort to start flowing, this effort being lower in the jams made at a higher temperature. Furthermore, they gave a flow behavior index less than unity, indicating pseudoplastic behavior. The jam valued as the best treatment showed values of moisture, protein, fat, fiber and ash like those reported in sweet potato and orange, blackberry, pineapple jams, among others. In addition, it presented values of soluble solids, pH and titratable acidity that are within the range established in the local technical standard.

Currently, color is considered a measurable quality criterion in foods such as nutritional quality, sanitary condition, colorant concentration, degree of maturity, quality control and process automation. The development of mathematical models to determine the loss of color of foods in enzymatic or non-enzymatic reactions was also carried out, since it allows predicting their behavior as a function of time and temperature. The process included the determination of the ripening index of Chinese cherry (Dovyalis abyssinica (A. Rich.) Warb.) as well as its nutritional composition, physicochemical characteristics and antioxidant activity. From the best prospectus, pulp was converted to analyze its color change in CIELab space by Luminosity, Chroma and Hue during jam making at four different temperatures, 120, 130, 140 and 150 Celsius degrees. The study indicated a higher luminosity at ripening stage three, which after the thermal process suggests a line regression for the loss of luminosity, chroma, hue angle and overall color variation values. As the thermal process progresses from intense orange and red colors to darker, paler and less intense colors, using an Arrhenius model, the changes in the values of these factors conform to a first order reaction. The results revealed that the Chinese cherry has a valuable nutritional composition, antioxidant activity, as well as physicochemical characteristics that technologically influence the production of jam.

Nowadays, the consumption of sugary products is a phenomenon that has been increasing significantly over time; the development of the food industry is the main cause of the increase in diseases, pathologies, metabolic and physiological alterations, due to the high number of ultra-processed products with a high content of free sugars. The purpose of this research is to develop a jam from raspberry (Rubus idaeus L.), blueberry (Vaccinium corymbosum L.) and blackberry (Rubus ulmifolius Schott), which are fruits rich in antioxidants, and can offer health benefits, seeking to reduce neurodegenerative and cardiovascular diseases, since the use of a natural sweetener reduces the caloric impact of the product on the consumer and the use of a gelling agent such as carrageenan is suitable for achieving a product with a similar texture to a conventional jam. For the elaboration of the product, several formulations were provided and by means of a sensory analysis the best treatment was determined, which was evaluated in its physicochemical characteristics, microbiology and total antioxidant content. From the results obtained, it was concluded that the treatment with the highest amount of carrageenan and natural sweetener had good sensory characteristics in terms of smell, taste, texture and a higher acceptability index than the other treatments. As for the most important attribute, texture, the results were positive and similar to a conventional jam.

Agroindustrial waste becomes increasingly larger as the population grows, raising concerns about environmental impact. New strategies are being sought to reuse valuable waste in the food industry. The research focuses on extracting pectin from four varieties of lemon (Citrus limon var. Lisbon, Citrus latifolia, Citrus medica and Citrus reticulata) due to the high environmental impact of lemon production, where currently only the pulp is used to manufacture pulps and concentrates. The extraction was carried out by conventional acid hydrolysis and microwaves. The extracted pectin was subjected to analysis by Fourier Transform Infrared Spectroscopy (FT-IR) and Titration to determine its esterification percentage. For the effect of the variation of pectin esterification on the gelation of jams, a texture analysis was carried out where hardness, adhesiveness and cohesiveness were evaluated. The extraction method with the highest yields was by conventional acid hydrolysis with 14.9; 13.4; 3.98 and 0.51 percent, for each variety of lemon. The FT-IR analyzes obtained similarities in the bands indicated by methyl ester groups, covering ranges from 1737.86 - 1741.72 wave number, likewise the peaks detected at 1020.34 - 1024.20 wave number, show linkage to the C-O-C symmetric group. The pectin extracted from Citrus latifolia presented a higher percentage of esterification of 99.8 percent, suggesting that more esterified pectins have a better gelling effect in jams. These results highlight that lemon residues are a valuable source of pectin, useful as a food additive.

The feasibility project for the implementation of a jam-processing plant using non-commercial quality strawberries (Fragaria sp) and sweeteners in the Rumiñahui canton, province of Pichincha, aims to determine its viability, considering three main aspects: market study, technical study, and economic-financial study that goes hand in hand with the organizational framework. Focusing on the use of raw materials that do not meet the usual standards of the food industry makes them the central nucleus of the strategy for the production of the final product. The market analysis focuses on the reception of the product among potential consumers in the urban area of the Rumiñahui canton, province of Pichincha, considering purchasing patterns, presentation preferences, and taste acceptance. Simultaneously, the technical study allowed the identification of the optimal formulation through sensory tests and the selection of the appropriate technology, with the design of facilities in accordance with the regulations in force in the country. In the organizational framework, the mission, vision, policies, and corporate identity are outlined. A simple hierarchical organization chart was designed to detail the responsibilities and professional profiles of each collaborator. Finally, the economic-financial study evaluated the economic feasibility of the implementation of the plant, considering a time horizon of five years, calculating the total amount required for the initial investment of the project and the financial indicators, such as break-even point, Net Present Value, Internal Rate of Return, Payback Period and Return on Investment.
