“…For rutin in the linear range of 1-50 ppm and for trans-ferulic acid in the range of 1-40 ppm. Limit of detection (LOD) was estimated as equal to three times the signal to noise ratio (S/N = 3) and the limit of quantification (LOQ) as 10× the signal to noise ratio (S/N = 10) (Santos, Oliveira, Ibáñez, & Herrero, 2014;Simon et al, 2015). The LOD is for rutin and trans-ferulic acid, respectively, 0.69 and 0.20 ppm.…”

The papaya fruit (Carica papaya L.) contains a wide variety of bioactive compounds with potential applications in the food and nutraceutical industries. The entrapment and release of such bioactive compounds remain a critical step for the development of functional, stable, and cost‐effective storage and delivery systems, since the interaction of polymers on capsules and the payload molecules can influence the performance of the capsule system under operational conditions. The present study describes the encapsulation of rutin and trans‐ferulic acid‐rich extracts from papaya exocarp in a pectin‐alginate composite, evaluating the performance of gallic acid encapsulation obtained through in situ and two‐step entrapment methods. The best alginate:pectin ratio for gallic acid encapsulation was 55:45 and 61:39, achieving 6.1 mg and 28.1 mg GAE/g capsules when the papaya exocarp extract was encapsulated by in situ and two‐step, respectively. We also evaluated the payload release performance of the obtained capsules under in vitro conditions simulating gastrointestinal conditions. Our results indicate an increased protective effect at gastric pH and targeted release of polyphenols when in situ encapsulation is used to encapsulate the extracts. Practical applications Currently, adding value to agroindustry processing waste is an important focus to achieve a more economically and environmentally sustainable food industry. The recovery of bioactive molecules such as polyphenols, for food supplements or formulation additives in the form of by‐product extracts is gaining importance as novel sustainable processes in the agricultural industry. Thus, the encapsulation of such bioactive extracts for storage and consumption is an active research field, aiming to overcome the low storage stability and lability to gastric conditions, currently hindering their applications in food or pharmaceutical formulations. In this sense, capsule design and the development of efficient encapsulation methods are very important to obtain a suitable carrier and protector system for the capsulated bioactive extracts or molecules. This research aims to add value to papaya waste and potentially to other agroindustry wastes such as pectin and alginate, resulting in a polyphenol carrier with excellent encapsulation and targeted release properties under gastrointestinal conditions. In conclusion, this kind of works could allow to the application of the agroindustry byproducts to obtain high added‐value products, in the form of polyphenol‐loaded capsules.

“…8 In the past few years, a number of adsorption materials have been used to treat industrial wastewater, such as activated carbon, carbon nanotubes, clay, zeolites, graphene, polymeric resins and modi-ed diatomites. 3,[9][10][11][12][13][14] Activated carbon is one of the most popular adsorbents because of its high porosity, strong interaction, chemical inertness and non-toxicity. However, most of their pore diameters are less than 2 nm, so that some bulky dye molecules cannot be captured on the inner surface of the pores, which limits the utilization ratio of the relatively large surface areas.…”

A new octahedral ZnO/ZnFe2O4 heterostructure has been fabricated through a facile surfactant-free solvothermal method followed by thermal treatment. It exhibits a record-high adsorption capacity (up to 4983.0 mg·g−1) of malachite green (MG), which is a potentially harmful dye in prevalence and should be removed from wastewater and other aqueous solutions before discharging into the environment. The octahedral ZnO/ZnFe2O4 heterostructure also demonstrates strong selective adsorption towards MG from two kinds of mixed solutions: MG/methyl orange (MO) and MG/rhodamine B (RhB) mixtures, indicating its promise in water treatment.
