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.

AbstractObjectiveTo investigate marketing techniques used on the packaging of child-oriented products sold through supermarkets.DesignFood and beverage products which met criteria for ‘marketed to children’ were recorded as child-oriented. The products were analysed for food categories, nutritional value, and type and extent of marketing techniques used.SettingA major supermarket chain in Adelaide, South Australia.SubjectsChild-oriented food and beverage products.ResultsOne hundred and fifty-seven discrete products were marketed to children via product packaging; most (75·2 %) represented non-core foods, being high in fat or sugar. Many marketing techniques (more than sixteen unique marketing techniques) were used to promote child-oriented food products. Claims about health and nutrition were found on 55·5 % of non-core foods. A median of 6·43 marketing techniques per product was found.ConclusionsThe high volume and power of marketing non-core foods to children via product packaging in supermarkets should be of concern to policy makers wanting to improve children's diet for their health and to tackle childhood obesity. Claims about health or nutrition on non-core foods deserve urgent attention owing to their potential to mislead and confuse child and adult consumers.

AbstractObjectiveFood marketing has been identified as a significant driver of the childhood obesity epidemic. The purpose of the present study was to (i) conduct a content analysis of the types of sports references that appear on supermarket food and beverage products and (ii) assess each product's nutritional and marketing profile.DesignThis was a descriptive study. Every product featuring sports references on the packaging was purchased in two major supermarkets during 2010. A content analysis was conducted and nutritional evaluations were made based on the Nutrient Profile Model, a validated nutrition model. Marketing data were obtained from The Nielsen Company.SettingTwo major supermarkets in Connecticut, USA.SubjectsFood and beverage products (n 102) were selected from two supermarkets.ResultsThe 102 products (fifty-three foods and forty-nine beverages) had sports references as part of their packaging: 72·5 % featured a character exercising, 42·2 % were endorsed by a professional sports entity and 34·0 % were child-targeted. The median nutrition score for food products was 36 (1 = unhealthiest and 100 = healthiest; scores of ≥63 are considered healthy according to this model). More than two-thirds of beverages (69·4 %) were 100 % sugar-sweetened. Children saw significantly more commercials for these products than adults.ConclusionsCompanies place sports figures on food and beverage products that are child-targeted and unhealthy.

Halal Food

Nowdays, muslim in the world are starting to realize the\at the development of science and technology has led to the problem of determination halal food and beverage products become simple. Demands clarity halal staus of a food product has become part of a global issue. It is not because of the Islmaic view of the halal statuse issue has broad implications covering various aspect of life. Thus, eating halal food products become sosial problems in the community as well as a responsibility of the state and the rights of citizens guaranteed by the Constitution of 1945 on the basis of the same idea, namely the insurance of halal products. The purpose of this stydy was to determine whether the regulations set by the goverment, al ready provide proctection to consumers to consume halal food products? In this study used normative juridical method with descriptive nature. Based on the research result and in the accordance with the issues that have been outlined, the regulations set bay goverment is still pasrtial, sectoral and overlap, so it didi not provide consumer protection on food labeled as halal.

Market segmentation is a division of consumer groups that have different needs, characteristics and behaviors (heterogeneous) in a particular market so that it becomes a homogeneous market unit, in this case it is very helpful in a more targeted marketing process so that company resources can be used effectively and efficient for example makes it easy to distinguish markets and recognize competitors with the same segment. CV. Lampegan Jaya is a company engaged in the distribution of food and beverage products including Meses Tulip Chocolate, Vita Zone, Bintang Sobo Tea, Preso Tea, Okky Jelly Drink, Fruit Tea, Bima Energy Nails, Coptic Cappuccino, Mizon and My Tea. These products are distributed to outlets spread across Bandung, Cianjur, Cileunyi, Cimahi, Soreang and Sumedang. Distribution of products is carried out based on the demand for outlets for the product. In this study a system of classifying customer segmentation based on products. This system can classify customers based on the number of purchases and area. The process of this customer grouping system uses a K-Medoid clustring algorithm to classify customers based on segmentation on the product purchase amount and area. With test data of 6 regions, 600 customer data and 28 products. Keywords: Market Segmentation, k-Medoids, , Food Products

Background and Purpose: To quantify workflow metrics in patients receiving stroke imaging (noncontrast-enhanced computed tomography [CT] and CT-angiography) in either a computed-tomography scanner suite (CT-Transit [CTT]) or an angio-suite (direct transfer to angio-suite—[DTAS]—using flat-panel CT) before undergoing mechanical thrombectomy. Methods: Prospective, single-center investigator initiated randomized controlled trial in a comprehensive stroke center focusing on time from imaging to groin puncture (primary end point) and time from hospital admission to final angiographic result (secondary end point) in patients receiving mechanical thrombectomy for anterior circulation large vessel occlusion after randomization to the CTT or DTAS pathway. Results: The trial was stopped early after the enrollment of n=60 patients (CTT: n=34/60 [56.7 %]; DTAS: n=26/60 [43.3%]) of n=110 planned patients because of a preplanned interim analysis. Time from imaging to groin puncture was shorter in DTAS-patients (in minutes, median [interquartile range]: CTT: 26 [23–32]; DTAS: 19 [15–23]; P value: 0.001). Time from hospital admission to stroke imaging was longer in patients randomized to DTAS (in minutes, mean [SD]: CTT: 12 [13]; DTAS: 21 [14], P value: 0.007). Time from hospital admission to final angiographic reperfusion was comparable between patient groups (CTT: 78 [58–92], DTAS: 80 [66–118]; P value: 0.067). Conclusions: This trial showed a reduction in time from imaging to groin-puncture when patients are transferred directly to the angiosuite for advanced stroke-imaging compared with imaging in a CT scanner suite. This time saving was outweighed by a longer admission to imaging time and could not translate into a shorter time to final angiographic reperfusion in this trial.
