In addition, the total content of tocopherols varied between 1450 and 1856 mg/kg and the δ/γ ratio ranged between 0.58 and 0.70. The oils from the accessions PER000408 (861 µg/kg) and PER000411 (896 µg/kg) were those with the higher volatile concentration, especially 1-hepten-3-ol, 2-nonanol, (<i>E</i>)-3-hexen- 1-ol, (<i>E</i>)-2-hexenal, and 1-hexanol.

They are denatured by heat treatment or bleaching and cleaned using enzymes. Among the various types of protein soils, blood soils are the most noticeable and known to be denatured by heat and bleaching by oxidation. We verified herein that the detergency of heat and oxidatively denatured hemoglobin is greatly improved by the enzyme immersing treatment in the detergency with SDS and can be analyzed using the probability density functional method. The probability density functional method evaluates the cleaning power by assuming that the adhesion and cleaning force of soils are not uniquely determined, but instead have a distribution in intensity, with a usefulness that had recently been demonstrated. This analytical method showed that the cleaning power of the enzyme immersing treatment improved when the soil adhesive force was decreased due to denatured protein degradation, even though the cleaning power of the SDS remained unchanged, and the values were consistent with those in the cleaning test. In conclusion, the probability density functional method can be used to analyze enzymatic degradation of denatured protein soils and the resulting changes in their detergency.</p>\u0000<p></p>\u0000<img alt=\"\" src=\"https://www.jstage.jst.go.jp/pub/jos/73/5/73_ess23262/figure/73_ess23262.jpg\"/>\u0000graphical abstract <span style=\"padding-left:5px;\">Fullsize Image</span>","PeriodicalId":16626,"journal":{"name":"Journal of oleo science","volume":"38 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140826757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The particle size curves showed the multimodal distributions. Compared to colloid milled samples, ball milled samples have smaller particle sizes and more uniform particle distribution.

The ball mill produced sesame paste with a wider range of hardness and silkier texture, and the samples made by ball milling for 30 min had the highest hardness.

DHA-containing microalgal oil was converted to ethyl esters (EE) as the raw material. In comparison to cooling, rotary-evaporation crystallization, as a post-treatment method for urea complexation, led to higher DHA contents in the non-urea included fractions. The ratios of urea to EE converted from DHA-containing microalgal oil was found to be the primary factors influencing urea complexation when using rotary-evaporation crystallization.

Primarily, Se-NPs was fabricated using the <i>C. forskohlii</i> leaf extract. The synthesized nanomaterial was characterized through UV-visible, XRD, and FTIR spectroscopies.

It consists of three molecules of fatty acids attached to one molecule of glycerol. Drug delivery system (DDS) is defined as a formulation to distribute drugs into the human body. The unique properties of MCTs have garnered interest in using them as excipients in DDS. Even though there are many significant effects attributed to the use of MCTs, especially in modulating the rate of drug delivery in various DDS, they are all limited and intermittent. This warrants a detailed summary of the previous studies on the use of MCTs in various DDS. Therefore, this review focuses on presenting a systematic review of previous studies on the use of MCTs in the last six years and explores the types and effects of MCTs on DDS that employ various types of delivery routes. A systematic search through PubMed, Science Direct and Scopus was performed. Keywords like “medium-chain triglycerides”, “medium-chain fatty acids”, “medium-chain triglycerides and their fractions”, “medium-chain fatty acids and their fractions”, “MCTs”, “MCFA”, “in drug delivery”, “in drug delivery system” and their combinations were used. The synonyms of the words were also used to extend the search. A total of 17 articles that met the inclusion criteria were identified. Findings from this review have identified the several MCTs and their fractions used in DDS that employed the oral/enteral, topical, transdermal, parenteral, and pulmonary routes of drug delivery. The review also highlights that the usage of MCTs in DDS results in a better transportation of drugs into the human body.</p>\u0000<p></p>\u0000<img alt=\"\" src=\"https://www.jstage.jst.go.jp/pub/jos/73/3/73_ess23204/figure/73_ess23204.jpg\"/>\u0000graphical abstract <span style=\"padding-left:5px;\">Fullsize Image</span>","PeriodicalId":16626,"journal":{"name":"Journal of oleo science","volume":"15 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140017573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
