Abstract A new technique (Flash Titration™) for the determination of total acidity and total alkalinity was applied to food and beverage analysis. Requiring no liquid titrants, Flash Titration is a technique made possible through microfabrication of electrochemical components on a silicon chip. Acidic or basic titrant was generated electrochemically at a noble-metal electrode that intimately surrounded an ion-selective, field-effect transistor pH sensor. As acid or base was generated through electrolysis, sample alkalinity or acidity, respectively, was neutralized in the immediate vicinity of the electrode. Through diffusion, a zone comprising a gradient of partially to totally neutralized sample expanded from the generating electrode into the volume element sensed by the nearby pH sensor. An analysis of the pH signal versus time revealed an end point inflection at an elapsed time related to the total alkalinity or acidity of the sample. End point times were typically a few seconds. In this paper, Flash Titration was applied to the analysis of a variety of samples, including juices, soft drinks, wines, and food products. The differences between the results obtained by the Flash Titration method and a commonly used conventional volumetric method were less than 2% in most food products tested. Analysis costs were reduced both through time saving and reduction or elimination of hazardous liquid titrant disposal, by the use of the Flash Titration method.

Near Future

Nowadays, near infrared (NIR) spectroscopy has experienced a rapid progress in miniaturization (instruments < 100 g are presently available), and the price for handheld systems has reached the < $500 level for high lot sizes. Thus, the stage is set for NIR spectroscopy to become the technique of choice for food and beverage testing, not only in industry but also as a consumer application. However, contrary to the (in our opinion) exaggerated claims of some direct-to-consumer companies regarding the performance of their “food scanners” with “cloud evaluation of big data”, the present publication will demonstrate realistic analytical data derived from the development of partial least squares (PLS) calibration models for six different nutritional parameters (energy, protein, fat, carbohydrates, sugar, and fiber) based on the NIR spectra of a broad range of different pasta/sauce blends recorded with a handheld instrument. The prediction performance of the PLS calibration models for the individual parameters was double-checked by cross-validation (CV) and test-set validation. The results obtained suggest that in the near future consumers will be able to predict the nutritional parameters of their meals by using handheld NIR spectroscopy under every-day life conditions.

Assalamu’alaikum Wr. Wb.Alhamdulillahirabbil ‘alamin. After a long wait for almost 12 years from the first stand, finally the scientific journal of the Department of Analyst Health (Medical Laboratory Technology) Universitas Muhammadiyah Palangkaraya can be published. BJMLT published every 6 months (2 issues/year) every October and April. The aim of this journal is to publish high-quality articles dedicated to all aspects of the latest outstanding developments in the field but not limited to Blood transfusion, Clinical Chemistry, Hematology, Histopathology, Immunology, Microbiology, Parasitology, Toxicology, Food and Beverage Analysis, Molecular Biology, Medical Biology, and related fields that are of interest to medical laboratory technologies, such as epidemiology, health promotion, professional ethics, and laboratory management, It was first published online in October 2018 using Open Journal System (OJS) 3.1 platform with e-ISSN 2622-6111 by URL http://journal.umpalangkaraya.ac.id/index.php/bjmlt.This edition contains 7 articles consisting of Hematology, Microbiology, Clinical Chemistry, and epidemiology topics. Editorial boards are fully aware that there is still room for improvement in this edition, hence with all humility willing to accept constructive suggestions and feedback for improvements to the publication for the next editions.The publication of BJMLT certainly participates in disseminating the results of research and review of science and technology development conducted by lecturers and researchers from UM Palangkaraya and other universities.The editorial board would like to thank the University, all editors and reviewers, and contributors of the scientific articles who have provided the repertoire in this issue. We hope that all parties, especially the contributors of the articles, could re-participate for the success of the publication in the next edition in October 2021. Wassalamu’alaikum Wr. Wb.
