1. Equine milk and its potential use in the human diet
Abstract Our objective was to address the use of equine milk for human consumption, highlighting important compositional aspects and peculiar characteristics of this milk. Equine milk stands out for its similarity to breastmilk in compositional aspects considering the quality of the protein and lipid fractions, and due to the presence of important bioactive

3. A comparison of dual-functional whey hydrolysates by the use of commercial proteases
Abstract Whey is well-known for the functional and bioactive properties of its proteins and peptides, which are of great interest to food and nutraceutical industries. The aim of this study was to investigate the effect of four different commercial proteases (Novo ProD® (NPD), Alcalase® (ALC), Pancreas Trypsin® (TRY), and Flavourzyme® (FLA)) in the gene

4. Effects of cow, goat, and buffalo milk on the characteristics of cream cheese with whey retention
Abstract Although cow milk is the most widely used dairy product, the milk of other animals presents characteristics relevant to the development of these products. Goat milk has higher digestibility and a lower incidence of allergic reactions than cow milk, while buffalo milk has higher levels of lipids, proteins and lactose. The objective of this work was

5. Chemical composition, percent of dietary reference intake, and acceptability of gluten-free bread made from Prosopis nigra flour, added with hydrocolloids
Abstract The objective of the work was to know the nutritional contribution of gluten-free bread made with Prosopis nigra flour, and the acceptability measured by celiac and non celiac persons. Gluten-free bread was made from a mixture of corn, rice and Prosopis nigra flours. To achieve better technological characteristics, xanthan gum and whey concentrate

6. Characterization of the interactions between chitosan/whey protein at different conditions
Abstract This research investigated the interaction between chitosan and whey protein molecules in terms of pH and heating. The FTIR, rheological analysis, turbidity, and zeta potential measurements were used to assess this interaction. At pH 4.0, addition of low amount chitosan with chitosan/whey protein isolate (C/WPI) ratio of 1:5 effectively prevented t

7. Obtainment, quantification and use of lactulose as a functional food – a review
Abstract Whey (milk serum) is produced by the dairy industry during the manufacture of cheese. In addition to being a valuable source of functional and nutritional proteins, whey also presents almost all the lactose from the original whole milk. However, many industries still consider the whey as an effluent, which can cause serious environmental problems wh

8. DETERMINAÇÃO ESPECTROFOTOMÉTRICA DE WPNI E HMF EM LEITE UHT ATRAVÉS DA ANÁLISE POR COMPONENTES PRINCIPAIS
During heat treatment milk suffers changes among which whey proteins insolubility and Maillard reaction can be monitored using spectrophotometric methods by determining the whey protein nitrogen (WPNI) and 5-hydroxymethylfurfural (HMF). The aim of this work was the evaluation of heat treatment in commercial UHT milk samples through HMF and WPNI determination

9. PARTIÇÃO DE PROTEÍNAS DE SORO DE LEITE EM SISTEMAS AQUOSOS BIFÁSICOS BASEADOS EM LÍQUIDOS IÔNICOS
In this work, we used an aqueous two-phase system (ATPS) consisting of the ionic liquid [C4mim][Cl] and the salt K2HPO4 to partition α-lactalbumin, β-lactoglobulin, and lactoferrin whey proteins. Extraction efficiency values above 87% indicate that the proteins primarily migrated to the ionic liquid-rich phase (top phase). Partition coefficient values rang

10. Adsorção de alfa-lactalbumina do soro de leite em hidroxiapatita: efeito do pH e da temperatura e análise termodinâmica
The nutritional and functional benefits offered by whey protein α-lactalbumin justify the great interest in its manufacture in large quantities at a high purity level. Hydroxyapatite is a calcium phosphate material able to adsorb proteins and can be synthesized at low production cost. Therefore, this work evaluated the adsorption of α-lactalbumin on hydrox

11. Action of a pancreatin and an Aspergillus oryzae protease on whey proteins: correlation among the methods of analysis of the enzymatic hydrolysates
The objectives of this study were to hydrolyze whey proteins using a pancreatin and an Aspergillus oryzae protease; to evaluate the degree of hydrolysis (DH) and the peptide profile; and to establish the correlations among the analytical methods. Ten hydrolysates were prepared at different reaction times and the highest DH was obtained by the protein content

12. Antimicrobial activity of a biosurfactant produced by Bacillus licheniformis strain M104 grown on whey
The aim of the present study was to investigate the antimicrobial effect of the lipopeptide biosurfactants produced by Bacillus licheniformis strain M104 grown on whey. The biosurfactant was investigated for potential antimicrobial activity by using the disc-diffusion method against different Gram-positive bacteria {B subtilis, B. thuringiensis (two strains)
