JOURNAL OF ENVIRONMENTAL MANAGEMENT 2022; 301:113945. [PMID: 34731956 DOI: 10.1016/j.jenvman.2021.113945] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Revised: 09/30/2021] [Accepted: 10/13/2021] [Indexed: 06/13/2023]
Abstract
Conversion of keratin waste to value-added products not only reduces waste volumes but also creates new revenue streams for the animal production industry. In the present study, combination of alkaline pretreatment of cattle hair with enzymatic hydrolysis was studied to produce keratin hydrolysates with relatively high antioxidant activities. Firstly, the effect of pretreatment conditions at a high solid/liquid mass ratio of 1:2 with different NaOH loadings and temperatures was studied. Increasing NaOH concentration from 1.0% to 2.5% and temperature from room temperature to 110 °C increased hair hydrolysis by keratinase and protein recovery in hydrolysates. Mild pretreatment with 1.5% NaOH at 70 °C for 30 min led to a protein recovery of 30% in the enzymatic hydrolysate. The resulting hydrolysate showed a high antioxidant activity, scavenging 69% of the ABTS radical with a low EC50 of 0.8 mg/mL. Severe pretreatment with 2.5% NaOH at 110 °C for 30 min resulted in a higher protein recovery of 45%, but a lower ABTS radical scavenging activity of 56% and a higher EC50 of 1.3 mg/mL. The reduced antioxidant activity was attributed to the reduced proportion of small peptides (<3 kDa) and the increased extent of amino acid chemical modification. This study demonstrated that controlling alkali pretreatment conditions could lead to the production of enzymatic hydrolysates with higher antioxidant activities for potential value-adding applications. The information generated from this study will aid scale-up and commercialisation of processes with optimised antioxidant peptide production.

Peptide Characterization and Functional Stability of a Partially Hydrolyzed Whey-Based Formula over Time. Nutrients 2021; 13:3011. [PMID: 34578889 PMCID: PMC8465316 DOI: 10.3390/nu13093011] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2021] [Revised: 08/23/2021] [Accepted: 08/25/2021] [Indexed: 11/16/2022] Open
Abstract
Human clinical trials have shown that a specific partially hydrolyzed 100% whey-based infant formula (pHF-W) reduces AD risk in the first yeast of life. Meta-analyses with a specific pHF-W (pHF-W1) confirm a protective effect while other meta-analyses pooling different pHF-W show conflicting results. Here we investigated the molecular composition and functional properties of the specific pHF-W1 as well as the stability of its manufacturing process over time. This specific pHF-W1 was compared with other pHF-Ws. We used size exclusion chromatography to characterize the peptide molecular weight (MW), a rat basophil degranulation assay to assess the relative level of beta-lactoglobulin (BLG) allergenicity and a preclinical model of oral tolerance induction to test prevention of allergic sensitization. To analyze the exact peptide sequences before and after an HLA binding assay, a mass cytometry approach was used. Peptide size allergenicity and oral tolerance induction were conserved across pHF-W1 batches of production and time. The median MW of the 37 samples of pHF-W1 tested was 800 ± 400 Da. Further oral tolerance induction was observed using 10 different batches of the pHF-W1 with a mean reduction of BLG-specific IgE levels of 0.76 log (95% CI = -0.95; -0.57). When comparing pHF-W1 with three other formulas (pHF-W2 3 and 4), peptide size was not necessarily associated with allergenicity reduction in vitro nor oral tolerance induction in vivo as measured by specific IgE level (p < 0.05 for pHF-W1 and 2 and p = 0.271 and p = 0.189 for pHF-W3 and 4 respectively). Peptide composition showed a limited overlap between the formulas tested ranging from 11.7% to 24.2%. Furthermore nine regions in the BLG sequence were identified as binding HLA-DR. In conclusion, not all pHF-Ws tested have the same peptide size distribution decreased allergenicity and ability to induce oral tolerance. Specific peptides are released during the different processes used by different infant formula producers.

Abstract
The European Commission asked EFSA to evaluate the efficacy of an infant formula, containing a specific protein hydrolysate derived from whey protein isolate and concentrate and manufactured by Société des Produits Nestlé S.A., in reducing the risk of developing atopic dermatitis in infants with a family history of allergy. This was following the submission of a dossier by Société des Produits Nestlé S.A. to the European Commission, in the context of Regulation (EU) 2016/127. The protein hydrolysate from which the infant formula is produced is included in Annex I and II of Commission delegated Regulation (EU) 2016/127 as suitable protein source for the manufacture of infant and follow-on formulae. This opinion does not cover the assessment of the nutritional safety and suitability of the infant formula or the safety of the food enzymes used in the manufacture of the protein hydrolysate. The Panel considers that, in relation to the effect that is claimed, the infant formula under evaluation is not sufficiently characterised with respect to the molecular weight distribution of peptides. From the human intervention studies submitted, no conclusions could be drawn on the efficacy of the infant formula in reducing the risk of developing atopic dermatitis. The Panel concludes that a cause-and-effect relationship has not been established between the consumption of the infant formula under evaluation and the reduction in the risk of developing atopic dermatitis in infants with a family history of allergy.

Abstract
Cow's milk protein allergy (CMPA) is one of the most common food allergies in infancy. Clinical food allergy guidelines recommend an extensively hydrolyzed formula (EHF) as the first-line treatment in nonbreastfed infants with CMPA. Designing and commercializing EHF poses both technical and regulatory challenges. Each manufacturing step, from sourcing of raw materials to release of the final product, needs to be managed in accordance with comprehensive quality systems. To avoid cross-contamination via externally sourced ingredients, suppliers should be carefully selected based on quality requirements. Strict zoning of the manufacturing areas according to contamination risk and air flow control are effective strategies to prevent accidental allergen contamination. Furthermore, dedicated manufacturing lines for hypoallergenic products are used to prevent potential cross-contamination from other products produced on the same line. The enzymatic hydrolysis, heat treatment and ultrafiltration used are specific to each manufacturer. Consequently, EHF are a heterogenous group of products with differences in the molecular weight profile of peptides, content of residual immunogenic cow's milk allergens, and residual in-vitro allergenicity. These differences are likely to affect clinical efficacy and safety. As not all commercialized EHF products have undergone formal testing in the laboratory and clinical trials, there is a need to develop guidelines for minimum technical and regulatory requirements for EHF products, including validated assays for ongoing quality control. Clinical trials assessing new EHF products for their hypoallergenicity and ability to support normal growth remain the definitive proof of efficacy and safety in infants and young children with CMPA.

Abstract
This article complements an earlier work published in 2015 Baron et al. (2015) that showed the interest of a shrimp shells bio-refining process. We compare here the effect of eleven commercial proteases at pH 3.5 or 4.0 on a residual amount of shrimp shells proteins after 6 h at 50 °C. The two pH are obtained when respectively 40 and 25 mmol of formic acid are added to 5 g of mild dried shell. Deproteinisation yield above 95% are obtained. Residual amino acids profile in the solid phase was identical for the eleven proteases except for pepsin which was similar to the raw material profile. A significant relative increase in the proportion of Glycine is observed for the ten other cases. Likewise, shapes of size exclusion chromatograms of the dissolved phase are similar except with pepsin.

Abstract
An RNAseq approach associated to mass spectrometry was conducted to assess the composition, molecular mass distribution and primary sequence of hydrolytic peptides issued from hydrolysates of white shrimp (Litopenaeus vannamei) by-products. High performance size exclusion chromatography (HPSEC) analyses indicated that 69.2% of the 214-nm-absorbing components had apparent molecular masses below 1000 Da, and 88.3% below 2000 Da. OFFGEL-nLC-MALDI-TOF/TOF and nLC-ESI-MS/MS analyses led to the identification of 808 peptides based on the NCBI EST databank (161,397 entries) completed by the new L. vannamei databank (58,508 entries) that we created from the RNAs of tissues used for hydrolysate production. Whereas most of hydrolytic peptides have a MW below 2000 Da, preliminary investigations of antimicrobial properties revealed three antibacterial fractions that demonstrate functional activities. The abundance of small peptides as well as the biological activities detected could imply very interesting applications for shrimp hydrolysate in the field of aquaculture feeding.

Abstract
We describe nutritional peptidomics for discovery and validation of bioactive food peptide and their health effects. Understanding nature and bioactivity of nutritional peptides means comprehending an important level of environmental regulation of the human genome, because diet is the environmental factor with the most profound life-long influence on health. We approach the theme from three angles, namely the analysis, the discovery and the biology perspective. Food peptides derive from parent food proteins via in vitro hydrolysis (processing) or in vivo digestion by various unspecific and specific proteases, as opposed to the tryptic peptides typically generated in biomarker proteomics. A food bioactive peptide may be rare or unique in terms of sequence and modification, and many food genomes are less well annotated than e.g. the human genome. Bioactive peptides can be discovered either empirically or by prediction: we explain both the classical hydrolysis strategy and the bioinformatics-driven reversed genome engineering. In order to exert bioactivity, food peptides must be either ingested and then reach the intestine in their intact form or be liberated in situ from their parent proteins to act locally, that is in the gut, or even systemically, i.e. through the blood stream. This article is part of a Special Section entitled: Understanding genome regulation and genetic diversity by mass spectrometry.
