Abstract:
... This study’s aim is to establish a new sensory sweetness definition and conversion method for five sugars. A “closed-type” question based on triangle test and paired comparison was used for sensory evaluation. The absolute threshold and nine sensory difference threshold values were determined and used to generate a sweet sensory difference strength curve. Defining absolute threshold of sucrose swe ...

Abstract:
... Malt syrup, as a low-cost substrate without any pretreatment, was proved to be able to replace maltose for ploymalic acid (PMA) production by Aureobasidium melanogenum GXZ-6. The PMA titer of 55.53 ± 1.72 g/L was obtained by batch fermentation in a 10-L fermentor with addition of malate, citrate and sodium malonate. Then, a higher PMA titer of 124.07 ± 2.28 g/L was obtained in fed-batch fermentati ...

However, in our previous work maltose was found to show significant interaction with GOD and based on this observation, a novel microplate-based method was developed to assess α-amylase inhibitory activity (GOD method). Concerns regarding the interaction of GOD with maltose h ...

The β-amylase (BAM) gene family is named for catalytic members’ ability to hydrolyze starch into maltose units. However, the family also contains proteins that are catalytically inactive, have additional domains, or are not localized with a starch substrate. Here we review ...
