“…Detection of H 2 O 2 is important in food, pharmaceutical, textile industries, and environmental protection (Zhang et al 2014b;Jv et al 2010). As an additive for microbial inhibiting or bleaching, H 2 O 2 has been used in food industry (Nascimento et al 2017). Due to the toxicity of residual H 2 O 2 , the presence of H 2 O 2 is not allowed in food under European Union and Japanese regulations (Hsu et al 2008).…”

Objectives: This report explores the possibility of synthesizing enzyme-metal-organic framework (MOF) composites by ink-jet printing.Results: This study demonstrates that the direct synthesis of patterned enzyme-metal-organic framework (MOF) composites on various substrates including paper and polymeric films can be readily achieved by ink-jet printing bio-inks containing protein molecules, metal ions, and organic ligands loaded, respectively, in different cartridges. The formed Cytochrome c (Cyt c)-MOF composites on filter paper by ink-jet printing can be used for rapid detection of hydrogen peroxide in solution. Conclusions:This technique opens possibilities of scalable, controllable, and designable fabrication of functional protein-MOF hybrid surface with promising applications in future bio-related application fields such as biosensing, wearable bioelectronics, artificial biomimetic membranes, and tissue engineering.

“…It is a known fact that color is an important parameter influencing consumer choice, being also an indicative of quality [47], which can influence the acceptability of human milk. Sousa, Delgadillo and Saraiva [48] stated that when the milk is subjected to a different processing, it is expected that changes in color may occur.…”

Human milk is the ideal nutritional support for premature neonates. Considering the need for aggregating nutritional value to human milk provided to such vulnerable group of infants, human milk was concentrated by the block freeze concentration technique. The effects of freeze concentration on the physicochemical properties, the efficiency of the process, color parameters, and the density and dynamic viscosity of human milk were assessed. The freeze concentration technology was used to successfully concentrate human milk to a factor equal to 180.48% and 72% of total solid retention in the second stage of freeze concentration. The values observed in the concentrates for the biochemical properties showed that the fraction of concentrated fluid human milk of the second stage (C2) presented elevated amounts of carbohydrates, protein and energy. The elevated caloric value observed in the ice fraction of the first stage (I1) refers to the retention of lipids in it. When added to human milk, C2 and I1 may satisfy the special requisites of nutrients and energy to guarantee the growth and development of preterm neonates.

“…Specifically, Nascimento and colleagues (Nascimento et al . ) note that over the period 2010–2016, 13.9% of papers published on determining milk adulteration used infrared spectroscopy. In addition, this combination has promise for the simultaneous detection of groups of adulterants.…”

Fourier transform infrared (FT‐IR) spectroscopy is widely applied for routine milk analysis. More recently, it has been used to detect a range of specific milk adulterants. Here, we show that the simultaneous use of targeted and untargeted models applied to FT‐IR spectra for detecting potential milk adulterants across relevant concentration ranges is an effective strategy. Using an appropriate validation strategy, limits of detection, sensitivity and specificity are determined for specific adulterants giving a useful guide to how these models would work in a practical situation. Finally, theoretical limits of detection of a range of potential adulterants are listed.
