Larger and more porous particles were formed by the agglomeration process, resulting in an improvement in powder flowability, wettability and solubility. The agglomerate with 0.1% GG binder exhibited higher viscoelastic properties than other agglomerates, with viscoelastic moduli values decreasing as the binder concentration increased (0.1–0.3%). The findings demonstrate that the agglomeration process with GG improved the powder characteristics of MPI and influenced its rheological properties.","PeriodicalId":13822,"journal":{"name":"International Journal of Dairy Technology","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141882512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 546 454 individual milk records were collected from the Years 2015 to 2020, from 264 003 cows in 2400 commercial dairy farms. Significant changes occur to the predicted FA profile of milk across the year, such as increases in unsaturated FAs including C18:1 n‐9 until April. This can be associated with the increasing proportion of fresh pasture in the cows' diet, and a decrease between September and October as the cows begin to transition indoors for the winter period. The opposite trend was noted for saturated FAs and in particular C16:0, where proportions decreased until April and increased between September and November. Milk produced between April and September also coincided with the lowest spreadability index, indicating a more beneficial milk FA profile for more spreadable butter texture during this period. This work provides a valuable reference resource at a national level of the FA profile of milk from pasture‐based spring‐calving dairy systems.","PeriodicalId":13822,"journal":{"name":"International Journal of Dairy Technology","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141865438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the formation of the tightest gel structure of malic acid‐Pickering emulsion gel, it showed the highest viscoelastic modulus, bound water content and gel stability. This work would introduce a novel method for the development of PEs with good gelatinisation and curcumin delivery system for food processing.","PeriodicalId":13822,"journal":{"name":"International Journal of Dairy Technology","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141778574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to analyse the levels of heavy metals and trace elements in raw milk from Kurdistan province using inductively coupled plasma mass spectrometry (ICP‐MS) following digestion via thermal block. Subsequently, the samples were evaluated for contamination with MRSA (methicillin‐resistant <jats:italic>Staphylococcus aureus</jats:italic>), taking into account the potential correlation between methicillin‐resistant strains and metal accumulation. Finally, milk safety was assessed based on the presence of toxic metals. A total of 180 milk samples were examined. Among them, 13.34% were found to be contaminated with <jats:italic>S. aureus</jats:italic>, and of those, 62.48% tested positive for MRSA. The metal concentrations (mg/kg) were measured as follows: arsenic 7 × 10<jats:sup>−2</jats:sup> ± 6 × 10<jats:sup>−3</jats:sup>, cadmium 4.70 × 10<jats:sup>−1</jats:sup> ± 9.70 × 10<jats:sup>−2</jats:sup>, lead 7 × 10<jats:sup>−2</jats:sup> ± 5 × 10<jats:sup>−3</jats:sup>, mercury 3 × 10<jats:sup>−2</jats:sup> ± 9 × 10<jats:sup>−3</jats:sup> and iron 4 × 10<jats:sup>−2</jats:sup> ± 9 × 10<jats:sup>−3</jats:sup>. Interestingly, arsenic, cadmium and iron levels were found to be correlated with the presence of MRSA. Additionally, there was an inverse relationship between toxic metals and essential ones in samples sensitive to methicillin (<jats:italic>P</jats:italic> &lt; 0.001). The Target Hazard Quotient (THQ) for cadmium is indicated at 9.94. Furthermore, the calculated Carcinogenic Risk (CR) parameters for cadmium and arsenic were 6.06 × 10<jats:sup>−3</jats:sup> and 2.22 × 10<jats:sup>−4</jats:sup>, respectively, suggesting that their concentrations fall within the carcinogenic range. The coexistence of MRSA and metal contamination in raw milk highlights the potential risks linked to its consumption. Consequently, the adoption of rigorous hygiene protocols is imperative to effectively address these concerns.","PeriodicalId":13822,"journal":{"name":"International Journal of Dairy Technology","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141778575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, colostrum demonstrated higher n‐3 and n‐6 fatty acids, which resulted in a lower n‐6/n‐3 ratio compared to mature milk.
