Special Issue Information

Dear Colleagues,

With the current development in biotechnology, several new enzymes with peculiar physicochemical characteristics and multiple uses have been mainstreamed. These capabilities are in continuous progress and expansion. Further, enzymes acquired from diverse microorganisms like yeasts, fungi, and bacteria are extensively used in countless food compositions for food preservation, enhanced organoleptic characteristics, and improved rheological properties. Furthermore, enzymatic techniques are economically advantageous and require less harsh chemicals, are effective in bioactive compound extraction, and produce harmless food products. Another essential aspect is enzyme immobilization, a genetic engineering strategy that enhances beneficial properties and increases food sector applicability. 

This Special Issue aims to contribute to the current knowledge in the field and provide the food industry with new enzymes, different applicabilities, and foresight into the evolution of valuable foods products. Articles focusing on enzymatic processes, biocatalytic methods, bioinformatics, and protein engineering are welcomed. In this Special Issue, we invite the submission of original research articles and reviews.

We look forward to receiving your contributions.

Appropriate addition of phosphate salt in food can improve the food quality and taste. However, extensive intake of phosphate salt may lead to some human diseases such as hyperphosphatemia and renal insufficiency. Thus, it is essential to establish a cost-effective, convenient, sensitive, and selective method for monitoring phosphate ion (Pi) to ensure food quality control. In this work, a Co-based metal-organic frameworks (Co-MOF) nanomaterial with dual functions (peroxidase-like activity and specific recognition) was designed for acting as a catalytic chromogenic platform for sensitive detection of Pi. The Co2+ nodes not only provide high enzyme-like activity to catalyze the 3,3′,5,5′--tetramethylbenzidine (TMB) substrate to blue oxTMB (652 nm) but also act as selective sites for Pi recognition. The use of cationic organic ligands (2-methylimidazole) and cationic metal ions (Co2+) endows the Co-MOF with a strong positive surface charge, which is beneficial to the capture of negative-charged Pi and the dramatically suppressed TMB oxidation. When Pi exists, it specifically adsorbs onto the Co-MOF through the Co-O-P bond and the strong electrostatic interaction, leading to the change of surface charge on Co-MOF. The peroxidase-like catalytic activity of Co-MOF is thus restrained, causing a different catalytic effect on TMB oxidation from that without Pi. Based on this principle, a colorimetric assay was established for rapid and sensitive detection of Pi. A good linear relationship was obtained between Pi concentration and the absorbance at 652 nm, with a linear range of 0.009–0.144 mg/L and a detection limit of 5.4 μg/L. The proposed assay was applied to the determination of Pi in actual food samples with recoveries of 92.2–108% and relative standard deviations (RSDs) of 2.7–7.3%, illustrating the promising practicality for actual samples analysis.

The impacts of dietary levels of oxidized vegetable (sunflower) oil on growth performance, gut morphology, nutrients utilization, serum cholesterol and meat fatty acid profile were evaluated in Ross 308 straight-run (n = 192) day-old broilers. The broilers were arbitrarily distributed among four dietary treatments including; FVO: fresh vegetable oil (1 mEq kg−1), LOO: low oxidized (20 mEq kg−1), MOO: moderately oxidized (40 mEq kg−1), and HOO: highly oxidized vegetable oil (60 mEq kg−1) with 5% inclusion containing six replicates. Results revealed that the broilers consuming MOO and HOO based diets showed reduced (p = 0.05) feed intake, body weight gain and carcass weight accompanied by a poorer feed conversion ratio than those consuming FVO. Villus height, villus height to crypt depth ratio, ileal digestibility of crude protein (p = 0.041), crude fat (p = 0.032) and poly unsaturated fatty acids (p = 0.001) in thigh muscles were decreased, whereas crypt depth (p = 0.001), serum cholesterol levels (p = 0.023) and short chain fatty acids (p = 0.001) were increased (p < 0.001) by increasing dietary oxidation level. In conclusion, MOO and HOO exerted deleterious effects on growth, carcass weight, gut development and nutrients utilization. Low oxidized vegetable oil (20 mEq kg−1), however, with minimum negative effects can be used as a cost effective energy source in poultry diets. Full article
