“…The time required for the emulsions to reach a peroxide value of 10 meq hydroperoxides/kg of emulsion was determined as a standard to measure the stability of emulsion. The limits of fat product (animal, plant and anhydrous) margarine and fat preparation were set <10 meq hydroperoxides/kg as a guarantee of the product quality [ 33 ]. When the peroxide value of the sample is measured as greater than 15 meq hydroperoxide/kg, the sample is considered rancid, which may alter the color, taste and nutritional quality due to the deterioration of the lipid.…”

Gentiana Lutea root (G. Lutea) is a medicinal herb, traditionally used as a bitter tonic in gastrointestinal ailments for improving the digestive system. The active principles of G. Lutea were found to be secoiridoid bitter compounds as well as many other active compounds causing the pharmacological effects. No study to date has yet determined the potential of G. Lutea antioxidant activity on lipid oxidation. Thus, the aim of this study was to evaluate the effects of an extract of G. Lutea on lipid oxidation during storage of an emulsion. G. Lutea extracts showed excellent antioxidant activity measured by DPPH scavenging assay and Trolox equivalent antioxidant capacity (TEAC) assays. An amount of 0.5% w/w G. Lutea lyophilise was able to inhibit lipid oxidation throughout storage (p < 0.05). A mixture of G. Lutea with 0.1% (w/w) BSA showed a good synergic effect and better antioxidant activity in the emulsion. Quantitative results of HPLC showed that G. Lutea contained secoiridoid-glycosides (gentiopiocroside and sweroside) and post column analysis displayed radical scavenging activity of G. Lutea extract towards the ABTS radical. The results from this study highlight the potential of G. Lutea as a food ingredient in the design of healthier food commodities.

“…The proportion of Graphite ([Graphite] 0 = 20 mg mL −1 ), BSA ([BSA] 0 = 2 mg mL −1 ) and r bs = 500 ± 10 m 2 /m 3 were constant for all of the results reported in this study, where r bs is the ratio of the overall surface area of the balls with respect to the solution volume. BSA is an inexpensive protein and most commonly found as a waste product in the meat industry [46,47], which plays a key role in preventing the aggregation of exfoliated platelets. While the large hydrophobic surface area of graphene nanosheet bonds with the hydrophobic segment of BSA, the hydrophilic fragment of BSA interacts with water molecules.…”

“…As the produced FLG aqueous solution is negatively charged, surface modifications to PI were crucial for improving the hydrophilicity of the substrate prior to printing [14]. Traditionally, conductive inks are printed using the commercial ink out of the nozzle onto the substrate either mechanically or thermally [36,47]. It is commonly reported that microscale cracks appear within the printed lines, rendering them susceptible to the deflection of the substrate.…”

“…It is commonly reported that microscale cracks appear within the printed lines, rendering them susceptible to the deflection of the substrate. In many studies, polymer stabilizers such as ethyl cellulose are added to the ink with the purpose of crystallization at the time of annealing [14,47]. Such binders are often insulators, and may not be the most effective post-processing method when it comes to the electronic applications of graphene [10,54].…”

Presented here is a scalable and aqueous phase exfoliation of graphite to high yield and quality of few layer graphene (FLG) using Bovine Serum Albomine (BSA) and wet ball milling. The produced graphene ink is tailored for printable and flexible electronics, having shown promising results in terms of electrical conductivity and temporal stability. Shear force generated by steel balls which resulted in 2–3 layer defect-free graphene platelets with an average size of hundreds of nm, and with a concentration of about 5.1 mg/mL characterized by Raman spectroscopy, atomic force microscopy (AFM), transmittance electron microscopy (TEM) and UV-vis spectroscopy. Further, a conductive ink was prepared and printed on flexible substrate (Polyimide) with controlled resolution. Scanning electron microscopy (SEM) and Profilometry revealed the effect of thermal annealing on the prints to concede consistent morphological characteristics. The resulted sheet resistance was measured to be R s = 36.75 Ω / sqr for prints as long as 100 mm. Printable inks were produced in volumes ranging from 20 mL to 1 L, with potential to facilitate large scale production of graphene for applications in biosensors, as well as flexible and printable electronics.

“…The animal protein industry generates large amounts of by‐products, ranging from 33 to 49% of the weight of the living animal, depending on the slaughtered species (Mullen, Álvarez, Zeugolis, Neill, & Drummond, ). Porcine liver is considered to be a by‐product of swine slaughter, which is rich in proteins and preeminent nutrients, such as Vitamins B12 and A (Nollet & Toldra, ; Seong et al, ; Shimizu et al, ). The porcine liver can be commercialized raw; however, it has a small consumer market.…”

Worldwide porcine slaughterhouses produce significant amounts of by‐products, such as porcine liver, daily. Even though the liver presents a very restricted market demand when raw, this product is composed of an exceptional nutritional content, with emphasis on protein, being, therefore, characterized as a potential raw material to produce protein hydrolysates. This article aimed to study the production of protein hydrolysate using the commercial enzymes Alcalase 2.4L™ and Novo Pro‐D™. For the development of this research, a central composite rotatable design with 4 axial points was applied for each enzyme. The factors evaluated were protein/water and enzyme/substrate ratios. The best hydrolysis results indicate average percentages of hydrolysis degree of 27.5% for both enzymes. The presence of low‐molecular‐weight peptides was also evidenced by the electrophoresis technique. It is, therefore, concluded that there is positive viability for the use of hydrolyzed porcine liver in differentiated food applications with an aggregate market value. Practical Applications At present, the worldwide growing dissemination of food scarcity has become a stimulus for the food industry to rethink the efficient use of raw materials to avoid waste and maximize the use of existing nutritional resources. A potential way of exploiting the nutritional value of the protein by‐products with no commercial applications is their transformation into protein hydrolysates by means of enzymatic processes. Protein hydrolysates have been in focus in the scientific community with industrial applications as beneficial products to the ingesting body, for acting as either nutraceuticals or functional bioactive foods. Commercialization of this type of product has become a growing market niche. Thus, this research, which presents an investigation regarding the conditions of the porcine liver hydrolysis, fits within current issues, with innovative potential of obtainment of bioactive peptides from by‐products.
