Abstract
(1) Background: In this study, the potential use of Dioscorea rotundata hydrocolloids was evaluated to develop low-fat mayonnaise. (2) Methods: The effect of different concentrations of hydrocolloids on the physicochemical, microstructural, and rheological properties of mayonnaise was evaluated. (3) Results: Physicochemical analyses showed pH values that were stable over time but decreased with increasing hydrocolloid concentration. The color parameters showed a decrease in luminosity and an increase in the values of a* and b* over time, which can be translated into an increase in yellow and a decrease in white, with a greater accentuation in the control sample. The rheological study allowed us to obtain a non-Newtonian flow behavior of the shear-thinning type for all samples, and the flow curves were well-fitted by the Sisko model (R2 ≥ 0.99). The samples had an elastic rather than viscous behavior, typical of dressings and emulsions. This indicates that the storage modulus was greater than the loss modulus (G′ > G″) in the evaluated frequency range. (4) Conclusions: hydrocolloids from Dioscorea rotundata have potential as a fat substitute in emulsion-type products.

Abstract
Hydrocolloids play a fundamental role in the design of new food products in their structure and functionality due to the interaction with the components of complex food matrices; for this reason, natural sources that are friendly to the environment must be sought for their extraction. A microstructure product such as mayonnaise is an oil-in-water-type emulsion design with the components of the complex varying from egg yolk, additives, spices, sugar, and other optional ingredients to improve its stabilities and organoleptic characteristics. The main objective of the study was to design and characterize the physicochemical, bromatological, and sensory analyses and rheological properties of the mayonnaise-type sauce formulated with hydrocolloids obtained from the epidermis of butternut squash (Cucurbita moschata) and xanthan gum. The rheological study allowed us to obtain a behavior of a non-Newtonian flow of the shear-thinning type for all the samples, and flow curves could be well described by the Carreau model (R 2 ≥ 0.993). The samples exhibit a more elastic than viscous behavior, with a higher storage modulus than the loss modulus (G' > G″) in the evaluated frequency range. When performing the physicochemical analysis, pH values (4.02-4.28), titratable acidity (0.40-0.48), peroxide index (12.5-20 meq), and a stable behavior were achieved in all the formulations except for MS2, which showed instability. Regarding the sensory evaluation, the MS3 sample reflected the closest values to the control sample, with a higher level of satisfaction. On the other hand, the bromatological analysis of MS3 presented a humidity value of 55.3 ± 0.27; carbohydrates, 7.66 ± 0.42; protein, 0.87 ± 0.02; fiber, 0.94 ± 0.05; and ash, 0.54 ± 0.05. The development of this product contributes to the transformation and agro-industrial use of the butternut squash (C. moschata); likewise, it allows us to obtain a mayonnaise-type sauce with organoleptic and nutritional characteristics for human consumption.

Development and in vivo evaluation of chitosan-gel containing Mitracarpus frigidus methanolic extract for vulvovaginal candidiasis treatment. Biomed Pharmacother 2020; 130:110609. [PMID: 34321177 DOI: 10.1016/j.biopha.2020.110609] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Revised: 07/22/2020] [Accepted: 08/02/2020] [Indexed: 02/08/2023] Open
Abstract
Vulvovaginal candidiasis (VVC) is characterized by inflammatory changes in the vaginal mucosa caused by abnormal colonization of Candida species. Traditional topical therapies using reference antifungal drugs usually present several issues and limitations for VVC treatment. Thus, the interest in new vaginal formulations, mainly those based on compounds from natural origin, has been growing over the last years. Methanolic extract from the plant species Mitracarpus frigidus (Willd. Ex Reem Schult.) K. Schum (MFM) has presented potential antifungal activity against C. albicans vaginal infection. Here, we aimed to develop and characterize a gynecological gel formulation based on chitosan containing MFM and to evaluate its anti-C. albicans effectiveness in the treatment of VVC. First, MFM was incorporated into a gel formulation based on chitosan in three final concentrations: 2.5 %, 5.0 %, and 10.0 %. Next, these gel formulations were subjected to stationary and oscillatory rheological tests. Finally, the gel was tested in an experimental VVC model. The rheological tests indicated pseudoplastic fluids, becoming more viscous and elastic with the increase of the extract concentration, indicating intermolecular interactions. Our in vivo analyses demonstrated a great reduction of vulvovaginal fungal burden and infection accompanied with the reduction of mucosal inflammation after MFM chitosan-gel treatment. The present findings open perspectives for the further use of the MFM-chitosan-gel formulation as a therapeutic alternative for VVC treatment.

Emulgels Containing Carbopol 934P and Different Vegetable Oils for Topical Propolis Delivery: Bioadhesion, Drug Release Profile, and Ex Vivo Skin Permeation Studies. AAPS PharmSciTech 2020; 21:209. [PMID: 32728887 DOI: 10.1208/s12249-020-01748-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Accepted: 07/05/2020] [Indexed: 01/02/2023] Open
Abstract
Topical administration can enable a more efficient therapy based on the improved bioavailability and patient compliance. Wounds and infections can lead to modifications of skin physiology and body protective function. Propolis (PRP) is utilized for skin protection and treatment. However, PRP extracts do not show suitable rheological characteristics and can cause irritation, pain, ulceration, and healing difficulties when they are administered on the harmed skin. Emulgels composed of Carbopol 934P (C934P) and different vegetable oils have been proposed for propolis extract release and may be a good strategy for topical delivery. The aim of this study was to investigate the bioadhesive properties, PRP release profile, skin permeation, and retention, by Franz's diffusion cell and photoacoustic spectroscopy (PS), of these emulgels. Formulations were composed of C934P and passion fruit oil (PF), sweet almond oil (SA), or andiroba oil (AO). PRP or by-product extracts were added to the systems, drug release profile was investigated, and porcine ear skin was utilized for analyses of bioadhesive properties, skin permeation, and retention. All formulations displayed similar bioadhesive force (0.05-0.07 N); PRP release was modified (prolonged), dependent on formulation composition, and mainly governed by diffusion. PS and analysis using diffusion cell showed that the systems could provide dermal permeation and retention, which was more effective for formulations containing AO. Considering the importance of propolis for many skin therapies, the emulgels containing AO for PRP delivery are worthy of biological studies and further clinical evaluation.
