When hyaluronidases act on isolated (as distinct from native) sodium hyaluronate, three changes in the properties of the substrate solution can be measured: (1) the decrease in viscosity, (2) the loss of ability to form insoluble protein salts on acidification, (3) the increase in reducing sugar content.’ Each of these changes is the basis for a quantitative method of measurement of enzyme acti...

Sweetpotato has rich nutrition, good ecological adaptability and high yield. There is a lack of knowledge about the effects of cooking methods on starch and sugar components in elite Chinese cultivars. In this study, sweetpotato storage roots from four cultivars "Xinxiang", "Jinyu", "Zimei" and "Yuzishu 263" were treated by baking, boiling and steaming and subsequently analyzed for starch conte...

INTRODUCTION The consumption of sugar-sweetened beverages (SSBs) is linked to excessive weight gain, diabetes, and risk of cardiovascular disease. We examined the association between SSB consumption and sociodemographic characteristics among Mississippi adults. METHODS We used data from the 2012 Mississippi Behavioral Risk Factor Surveillance System, which collected information on SSB consump...

OBJECTIVE To explore whether the effects on dietary behaviours of a computer-tailored intervention aimed to prevent excessive weight gain among adolescents, FATaintPHAT, were moderated by sociodemographic, cognitive and home environmental factors. DESIGN A two-group cluster randomized trial. Potential moderation of the outcome measures (consumption of sugar-sweetened beverages, snacks, fruits...

Starch accumulation and breakdown are vital processes in plant storage organs such as seeds, roots, and tubers. In tubers of potato (Solanum tuberosum L.) a small fraction of starch is converted into the reducing sugars glucose and fructose. Reducing sugars accumulate in response to cold temperatures. Even small quantities of reducing sugars affect negatively the quality of processed products s...
