“…The value of the chroma (C*) or color intensity was similar to the value of b* (7.17), which represents a slight yellow color that combined with the value of L*, on the color spectrum reflects the brown color, confirmed by visual observation. The color change in the mucilage was already expected, since the leaves used for the extraction of the mucilage went through successive process steps such as cutting, grinding, agitation, heating, drying, the oxidation of the thermosensitive constituents, changing the color from green to brown (Silva, Amaral, Junqueira, Leite, & Resende, 2017).…”

Innovative materials for the encapsulation of bioactive compounds are a permanent challenge. In this sense, the purpose of the study was to evaluate the use of Ora-pro-nobis mucilage (MOPN) as a wall material to replace Arabic gum (AG), in microencapsulation by complex coacervation of bocaiuva (Acrocomia aculeata) pulp oil. The MOPN was obtained from green leaves, and the pH, color, water activity, humidity, fixed mineral residue, proteins, lipids, and extraction effectiveness were determined. MOPN was employed as a partial or total replacement of AG in the microencapsulation of bocaiuva pulp oil. Dehydrated and wet mucilages were used to emulsion formation. The interaction between biopolymers, the effectiveness, efficiency of microencapsulation, and the morphological characteristics of microcapsules were confirmed. In addition, the bioactive compounds (chlorophyll and β-carotene) and antioxidant activity were evaluated. The microcapsules were produced using moist mucilage. Microcapsules obtained with AG/gelatin/ bocaiuva oil were considered as control samples. MOPN showed brown color and chlorophyll content of 72.44±5.74 mg 100 g-1. The interaction between AG and MOPN in microcapsule formation was proven for the formulations with 25 and 50% MOPN substitution. The effectiveness was 74.83 and 75.22%, and encapsulation efficiency was 79.18 and 74.59%, respectively, verified through optical micrograph. In addition, the microcapsules with 25 and 50% MOPN as wall material showed three times more antioxidant activity against ABTS, and two times more β-carotene compared to the control microcapsule.

“…Protein adsorption by activated carbon increases with increasing temperature [121]; this might provide a potential solution to blood digestion in thermophilic operation. Increasing the quantity of activated carbon added increases the protein adsorption because it increases the surface area, leading to less protein degradation and thus reducing the amount of ammonia present to inhibit the microorganisms.…”

Blood from livestock slaughtering imposes a high organic pollution load and risks. If it is discharged untreated to sewer systems, it increases the organic pollution load on wastewater treatment plants by 35–50%. This paper reviews blood anaerobic digestion. It analyzes the quantities, composition, methane potential reported, microbiology, biochemical pathways of blood protein degradation, environmental and health issues, and strategies suggested to manage them during livestock blood anaerobic digestion. Although challenging, anaerobic digestion of blood as a mono-substrate is possible if the culture-reactor system is controlled based on a complete characterization and understanding of the microbial community and its metabolic activities. Co-digestion of blood and other feedstock proceeds well if the mixtures are well designed. Generally, the specific methane yield from digesting blood alone ranges between zero and 0.45 m3 kg−1 protein, whereas for co-digesting blood and other substrates, the yield varies between 0.1 and 0.7 m3 kg−1 volatile solids. More research is required for microbiology and kinetics, the role of adsorbents, reactor configuration, and culture adaptation during anaerobic digestion of blood to better control the process.

“…It describes the effect of amino acids on yeast extract before and after adsorption. The situation occurs because activated carbon can adsorb several types of amino acids [6]. All types of amino acids can be adsorbed due to amino acids adsorbed not only on the conditions of free amino acids in the form of protein but consist of various amino acids.…”

Ethanolic fermentation can produce byproducts such as yeast containing intracellular amino acid that is used as a raw material of cosmetics. Residual yeast fermentation as sludge was dissolved and extracted by autolysis at 50°C for 24 hours, so we get the product in the form of intracellular content of the yeast Saccharomyces cerevisiae. Purification of dye and odor yeast extract was conducted by using an activated carbon column adsorption with ratio 1.5:10 yeast extract solution (g / mL) for six times recycle or until it reaches the absorbance value of 0.020. The content of yeast extract in the form of amino acids was analyzed by High-Pressure Liquid Chromatography method. Analysis of the feasibility test yeast extract as cosmetic raw materials made through the pigment deposition method by inhibit tyrosinase activity. 0.05 g yeast extract before adsorption (pale yellow) produce 62% inhibition of tyrosinase 3130 U / mL. Dry yeast extract after adsorption (odorless) had 96% inhibition of tyrosinase 313 U / mL, whereas placental extract by 89% inhibition of tyrosinase 313 U / mL. These results indicate odorless yeast extract can replace placental extract as an alternative to cosmetic raw materials.
