“…During the last decade, a global tendency toward the use of essential and vegetable oils in the fields of food, agricultural and pharmaceutical industries has emerged due to their functional properties, wide acceptance, and natural status. [ 1 ] Chia oil (CO) has gained popularity thanks to its content in α‐linolenic acid (around 60%), higher than any other edible seed‐based source. [ 2 ] However, the major presence of hydrophilic antioxidants in the seeds and the susceptibility of polyunsaturated fatty acids toward oxidation are the main disadvantages faced when developing strategies to incorporate CO in different food products.…”

Chia oil (CO) has gained popularity given its 𝜶-linolenic acid content (around 60%). Nonetheless, the susceptibility of polyunsaturated fatty acids toward oxidation represents a challenge for incorporating CO in different products, which justifies the need for exploring stabilization methods. To the best of the authors' knowledge, no reports about powders based on chia oil blends are published. Therefore, the objective of this research is to evaluate the stability at room temperature of microencapsulated CO blends [with virgin sesame (VSO) and wheat germ (WGO) oils] and microencapsulated CO with the addition of tert-butylhydroquinone (TBHQ). Spray-drying yielded powders with a better encapsulation efficiency, flowability, and stability, compared with freeze-drying. After a storage test performed during 3 months, the highest hydroperoxide content (>100 meq.O 2 kg −1 oil) is observed for the microencapsulated CO/WGO 80/20 blend, despite its 𝜶 and 𝜷-tocopherol contents and its antioxidant activity (>90% inhibition of DPPH radical). Notwithstanding, bulk and microencapsulated CO-TBHQ, CO/VSO 80/20, and 20/80 showed hydroperoxide contents <8 meq.O 2 kg −1 oil. By the end of the test, the highest induction period is observed for the microencapsulated CO/VSO 20/80 blend (19.85 ± 0.18 h). Finally, the drying method and the core formulation greatly affect the stability of microcapsules. Practical Applications: Addition of antioxidants, oil blending and microencapsulation are technological solutions for the preservation of omega-3-rich oils, which are popular among healthy food consumers. This research studies and compares the microencapsulation processes by spray or freeze-drying in order to preserve chia oil blends (with virgin sesame and wheat germ oils) and chia oil with the addition of antioxidants, thereby taking the advantages of the three technological solutions mentioned above. Stable omega-3-rich powders, with a higher oxidative stability than pure chia oil, can be obtained as ingredients for the food industry. This ultimately allows the incorporation of the oil into different food products developed to satisfy specific market tendencies.

In recent years, there has been considerable interest in using microalgal lipids in the food, chemical, pharmaceutical, and cosmetic industries. Several microalgal species can accumulate appreciable lipid quantities and therefore are characterized as oleaginous. In cosmetic formulations, lipids and their derivatives are one of the main ingredients. Different lipid classes are great moisturizing, emollient, and softening agents, work as surfactants and emulsifiers, give consistence to products, are color and fragrance carriers, act as preservatives to maintain products integrity, and can be part of the molecules delivery system. In the past, chemicals have been widely used but today’s market and customers’ demands are oriented towards natural products. Microalgae are an extraordinary source of lipids and other many bioactive molecules. Scientists’ attention to microalgae cultivation for their industrial application is increasing. For the high costs associated, commercialization of microalgae and their products is still not very widespread. The possibility to use biomass for various industrial purposes could make microalgae more economically competitive.

“…Since the oils are mostly lipophilic, they have a good miscibility with the solid lipids in the lipid matrix, resulting in a high amount of oil encapsulated within the nanosystem (Falcão et al, 2015, p. 568). Thus, these carriers have the potential to protect the labile and sensitive components of the oil from chemical, photochemical or oxidative degradation, since, due to immobilization by solid lipids, nanocarriers serve as a barrier between the encapsulated oil and the environment Another intended feature of the use of NLC as a carrier of vegetable oils is to provide a controlled release pattern, seeking to improve their bioavailability, reduce toxicity and thus increase patient compliance (Lammari, et al, 2021;Vieira et al, 2020).…”

The demand for analytical methods for drug quantification is an obstacle in the research and development of new products, due to the need to use simpler techniques for the identification and quantification of the actives. Although it is a very sensitive and selective technique for these determinations, high performance liquid chromatography (HPLC) requires expensive instrumentation and well-trained analysts, while spectrophotometry is fast, low-cost and hardly requires sample pre-treatment. Thus, this study aimed to develop a quantification method by UV-visible spectrophotometry for salicylic acid (SA) encapsulated in nanostructured lipid carriers (NLC) containing copaiba oil. The method was validated according to national and international criteria (ANVISA, ICH and FDA). The diluent was a mixture of absolute ethanol and phosphoric acid (99:1) and detection was performed at 310 nm. The interference of the matrix in relation to NLC-SA was minimal (0.37%), demonstrating the selectivity. Linearity was obtained in the range of 5.0 30.0 μg/mL (r = 0.99948) and the method proved to be accurate, with high recovery of SA in the presence of the other components (over 96% recovery), with precision at two levels: intra- and inter-days (DPR < 5%). Detection and quantification limits were 0.51 e 1.70 μg/mL, respectively. Finally, according to the Youden test criteria, the method was robust in the face of the proposed variations, obtaining effect values lower than the critical value (0.07). Therefore, the developed method is accessible, effective and valid for the quantification of SA in complex matrix lipid nanoparticles.
