“…Rice (Oryza sativa L.) is considered a staple food by a significant part of the world's population (Papillo et al, 2018). In the last years, grains of pigmented rice, such as black rice, have gained attention because this type of rice has benefits to health, due to bioactive pigments located in its bran layer, which contains higher content of phenolic compounds (Paiva et al, 2014;Vargas et al, 2018).…”

The present study aimed to assess the drying kinetics of black rice and fit different mathematical models (empirical and diffusive) to the experimental data, and evaluate the effect of drying air temperature on the physical-chemical and bioactive compounds quality of black rice. Drying air temperatures ranged from 40 to 80 ºC and the drying air speed was 1.5 m/s. Physical-chemical characterization of the product was based on the following parameters: moisture, water activity, ashes, total protein content, pH, total acidity, lipids, total carbohydrates, total anthocyanins, flavonoids, total phenolic compounds and antioxidant activity. Among the empirical models, Page showed the lowest mean squared deviations (MSD) and highest coefficients of determination (R2). For the diffusion model, the values of effective mass diffusivity and convective heat transfer coefficient increased with increasing drying air temperature, and the Biot number indicated that the first-type boundary condition would also describe well the drying process. Physical-chemical parameters and bioactive compounds differed between the temperatures used, and the temperature of 60 ºC led to the best relationship between drying time and preservation of product characteristics.

Henna (Lawsonia inermis L.) leaves have been widely used as a natural plant colorant for hair dyeing and body art. However, the utilisation of henna dye extract in commercial colour cosmetics is compromised by its potential harmful effects to humans. This study demonstrates that spray‐drying encapsulation using maltodextrin and gum arabic as biocompatible polymeric carriers can be used as a promising strategy to detoxify henna dye extract while maintaining its hair dyeing efficiency for cosmetics. Henna extract‐loaded microcapsules with an average particle size of 4.1 μm were prepared with an excellent encapsulation efficiency (98.4%) and a negative zeta potential (−34.4 mV). The morphology and physicochemical properties of the microcapsules were characterised by comparison with a spray‐dried sample of neat henna extract. The in vitro toxicological results showed that the microencapsulation process significantly reduced the contact toxicity of henna extract towards human epidermal keratinocytes as well as to the eyes and skin. The encapsulated henna extract also exhibited improved storage stability at three different temperatures (4, 25 and 50°C) for 14 days. Furthermore, the microcapsules demonstrated satisfactory hair dyeing efficiency as natural colorants with good colour fastness towards light and washing.

BackgroundExtract of ciriguela residue was microencapsulated by spray‐drying and freeze‐drying using maltodextrin (M), gum Arabic (GA) and their mixture (50%M; 50%GA on dry basis) as encapsulating agents. Total phenolic compounds (TPC), antioxidant activity, physicochemical properties, profile of phenolic compounds by High‐Performance Liquid Chromatography with Diode‐Array Detection (HPLC‐DAD), and storage stability were evaluated.ResultsTPC content of powders ranged from 306.9 to 451.2 mg GAE/g dry powder. The spray‐dried powder prepared using GA as encapsulating agent had higher TPC content and antioxidant activity, while the freeze‐dried powder had lower moisture and water activity. Spray‐dried microcapsules had spherical shape, while freeze‐dried products irregular structures. Profile of phenolic compounds identified in samples was similar, with rutin (342.59 μg/g and 72.92 μg/g) and quercetin (181.02 μg/g and 43.24 μg/g) being the major compounds in liquid and freeze‐dried extracts, respectively, while myricetin (97.41 μg/g) being predominant in spray‐dried ones. Storage stability tests carried out for 45 days at 7 °C or 25 °C revealed no statistically significant difference in TPC.ConclusionCiriguela residue can be considered a source of TPC and used as ingredient with good antioxidant activity in the food industry.This article is protected by copyright.
