This study arose from the need to develop instant beverages with better nutritional characteristics, considering the limited availability of powdered products made from tropical fruits and vegetable oils. The purpose of this research was to formulate and characterize a powdered mixture based on microencapsulated pineapple pulp and flaxseed oil for the preparation of instant beverages. The methodology involved obtaining the powder mixtures by spray drying using encapsulating agents such as maltodextrin and gum arabic, and developing three formulations, which were evaluated by physicochemical analysis and sensory evaluation. The attributes evaluated were color, odor, texture (mouthfeel), flavor, and acceptability. The best treatment underwent proximal analysis (protein, fat, and dietary fiber), as well as microbiological analysis. The results showed that the beverage made with the powder mixture containing 80 percent pineapple pulp and 20 percent microencapsulated flaxseed oil had the highest sensory acceptability, highlighting an adequate balance between soluble solids, acidity, and pH. Likewise, nutritional analysis of the powder mixture revealed a significant content of dietary fiber and fatty acids. It is concluded that the formulated powder mixture is a useful alternative with favorable sensory properties for consumers. These results demonstrate that it is of good quality and ideal for consumption because it complies with current regulations.

Lupin is an Andean legume with great nutritional potential. The lack of alternatives to its traditional use represents a challenge for large-scale lupin oil production due to the absence of standardized parameters in the extraction process. The study aimed to analyze the operating parameters that influence the yield and composition of lupin (Lupinus mutabilis sweet) oil. A methodology was used that included mechanical extraction at two different ratios using the Flora Power equipment to evaluate yield under different humidity conditions, gas chromatography for the analysis of fatty acid composition, and the oxidative rancidity test in Oxitest to establish the oil's shelf life. The results revealed that Treatment 2 was the most efficient, achieving the highest oil yield under conditions of lower seed moisture and greater equipment efficiency in the extraction process. The lipid profile of the oil showed a high content of unsaturated fatty acids, particularly oleic acid. The shelf life ranges from 10 to 13 days without any refining process. Research highlights the cardiovascular health benefits conferred by the high concentration of monounsaturated fatty acids, thus contributing to a product with promising nutritional and functional characteristics for the market.

Oenocarpus bataua, commonly known as ungurahua, is an endemic palm from South America’s Amazon region, high valued for its content of vegetable oils and bioactive compounds. The extraction of these oils has been carried out by ancestral techniques and, most recently, conventional methods. However, there are non-conventional alternatives, such as extraction with subcritical propane, whose application in ungurahua has not yet been documented. In this study, global yield, antioxidant capacity, and fatty acid profile of extracted oils by subcritical propane and Soxhlet with hexane were compared. The raw material was characterized prior to extraction with both methods to determine the extraction yield. Antioxidant activity was evaluated using DPPH technique and fatty acid profile was analyzed by thin-layer chromatography (TLC). The fat content in the sample was 21.7 percent. The subcritical propane method showed a higher yield, reaching 27.28 percent, while the Soxhlet method achieved 24.06 percent. Likewise, the antioxidant capacity was higher in the oil extracted with subcritical propane, with 362.5 micromoles of Trolox per gram of extract, compared to 299.4 using the Soxhlet method. Both methods produced extracts with similar TLC profiles, showing the presence of various fatty acids, sterols, and other polar molecules, which contribute to the observed antioxidant activity. ANOVA analysis revealed significant differences in antioxidant capacity between the two extraction methods, whereas no such differences were observed in extraction yield.

Skin aging is caused by internal and external factors that precipitate a natural process, which has great repercussions within society. Currently, it has gained greater importance in different scientific studies with the aim of treating bad skin care habits, whether they are caused by climate changes and the use of conventional cosmetics. A feasibility study was prepared to corroborate the acceptance of a facial cream. In the market study, a survey was carried out on people between the ages of 35 and 49, where the demand, supply, and competition of cosmetics were recognized to determine the acceptance of the product. The technical study establishes the size of production, location, and engineering of the project, detailing the technical and scientific part of the product. In the economic study, the costs, investments, cash flow and sales required for the establishment of the plant were described. Finally, in the financial evaluation, the indicators were calculated where it was reflected that the project is profitable and viable according to the cost/benefit indicator of the investment, which was 1.67 for its execution in the cosmetic market. Faced with this situation, the need arises to develop an anti-aging moisturizing cream based on avocado oil and hyaluronic acid, implementing biotechnology in the production and quality control processes, taking advantage of the molecular synergy of plants to create new enhancing additives for facial care.

Sacha inchi (P.volubilis) and chia (S.hispanica) oil are the natural source with the highest percentage of unsaturated fatty acids known. They are mainly composed of alpha-linolenic acid and linoleic acid and are consumed for their high nutritional value. In contrast, the large amount of unsaturation in their structure makes them susceptible to oxidation. The objective of this research was to increase the oxidative stability of oils in a 50:50 (w-w) ratio. For this purpose, the use of alpha-tocopherol and butylated hydroxytoluene in the microencapsulation process by spray drying (SA), adsorption coating (RV) and spray drying with adsorption coating (SA-RV) was evaluated. An accelerated oxidation test was performed and determined that the RV samples with N-ZORBIT 2144 exhibited longer shelf life compared to SA and SA-RV. The results of the experimental design suggest that the use of adsorption coating gives a higher level of protection than spray drying. Thus, the type of process, antioxidant and their interaction affect the oxidative stability of the oils.

Degradation of polyunsaturated fatty acids is a common problem in vegetable oils, usually caused by exposure to different environmental conditions; natural antioxidants such as essential oils and industrial methods such as microencapsulation are commonly used to ensure the reduction of these degenerative processes and prolong their shelf life. The objective of this research is to microencapsulate sacha inchi oil in combination with the essential oils of lemon eucalyptus and basil by spray drying, using a mixture of maltodextrin, arabic gum and sacha inchi in a 1:1:1 ratio together with the essential oils in concentrations of 0.5, 0.4 and 0.5 percent respectively, with an inlet temperature of 150 degrees Celsius. Applying FTIR-ATR (Attenuated Total Reflectance) spectrophotometry, the efficiency of microcapsulation was evidenced. Fluidity and compressibility were evaluated by means of the Hausner and Carr indices, each mixture showed relatively poor indices compared to its limit, greater than 38 for Carr and greater than 1.6 for Hausner. The antioxidant capacity was evaluated by the DPPH test with dilutions of 1 over 200, 250 and 300 for each mixture of microencapsulates, diluting 0.1 g of each sample in 20, 25 and 30 ml of distilled water, respectively. It was concluded that the oil mixture of sacha inchi oils together with lemon is superior in comparison to the three previously mentioned, presenting Carr and Hausner indexes of 42.23 and 1.42 respectively and an antioxidant capacity of 326.74 micromol per liter of the Trolox compound.

Several molecules of the hemp plant, such as CBD and THC, have been shown to be effective as treatments for psychiatric and other conditions such as sleep disorders, migraines, cancer pain, seizures and skin diseases. However, social stigma about the cultivation and consumption of this plant limits access to these treatments despite the fact that CBD has no psychoactive properties. The present study focused on making a microencapsulated product that combines the medicinal benefits of the hemp plant with the addition of sacha inchi oil, which is rich in fatty acids and vitamins, as an added value. To this end, an emulsion was made from a mixture of hemp, sacha inchi and sunflower oils together with gum arabic and maltodextrin, which fed a spray dryer to obtain a whitish powder, obtaining a yield of 63.87 percent in the best treatment, Subsequently, tests were carried out on the microencapsulated product where it was determined that it obtained an average humidity of less than 1.5 percent in the first week after it was obtained and 2.9 percent after 10 weeks of storage, it was also obtained that the fluidity of the microencapsulated product was not very acceptable even after the application of excipients to improve the fluidity, finally an infrared FTIR-ATR test was carried out where a good level of microencapsulation was qualitatively determined.

The addition of fatty acids to food products represents a challenge, due to the low stability and poor acceptability of these components. Microencapsulation is an alternative to take advantage of their benefits. In contrast, in the present study, a mixture of Sacha Inchi and Chia oils (MA) in a 2:1 ratio was microencapsulated by spray drying, using gum arabic and maltodextrin, oil load of 33 percent, inlet temperature of 150 and outlet temperature of 90 degrees Celsius, reaching an efficiency of 68.20 percent. Characterization by electron microscopy showed microcapsules (MC) with continuous, crack-free walls. Agglomerations were observed, the size range found was between 9.02 and 22.99 microns. Infrared spectroscopy analysis was performed, which confirmed the microencapsulation of the AM by decreasing the characteristic bands of the fatty acids. The oxidative stability of the MC supplement, free of preservatives and without packaging, was determined using the Oxitest reactor (Model V02M2U) and the AOCS Cd12c-16 method. Induction times exhibited a decrease in the samples with MC. The shelf life was calculated through a mathematical extrapolation at 15 and 20 degrees Celsius, presenting a reduction from 3.37 to 0.37 months and from 2.06 to 0.25 months, respectively, compared to the blank sample. With the results obtained, it was determined that the inclusion of MC in the supplement has a negative effect on the shelf life, however, the sensory attributes improved.
