The reducing sugars include glucose, fructose, and galactose as monosaccharides and lactose and maltose as disaccharides (Figure 1).. Molecular structures of the reducing sugars.. 6 Reducing sugars are important not only for food, but are an indispensable component of biological samples such as of blood, serum, plasma, and tissue.

According to Liu et al. (2008) the total sugars and sucrose varied from 11–13% and 6–9%, respec- tively in SJ. Wu et al. On the other side only 29.32% and 18.8% of the total car- bohydrates of raw SS and SG, respectively were found as total sugars. Reducing sugars represented 76.39% and 60.56% of the total sugars in both of SS and SG, respectively.

This decrement could be due to hydrolysis of the non-reducing sugars in the acidic media during storage. On the other hand, total sugars slightly decreased during storage of products, which could be related to the browning reaction between free amino acids and reducing sugars. Results in Table 4 showed Table 4 Effect of storage periods at room temperature on chemical properties of canned pumpkin and pineapple..

These data are in same line with those reported by (El-Beltagy et al., 2009). 0.05) differences between rotary evaporator and micro- wave methods in dry matter, total sugars and reducing sugars, dry matter, total sugars and reducing sugars of date flesh were and 75.2%, respectively. A considerable amount of non reducing sugar was found, as their content was 2.50% of its total sugar content in date flesh. Similar results are found with other types of dates (Mustafa et al., 1983.

Cocoa-like flavor compound development of rambutan seed fat as the effect of fermentation and roasting

tailieu.vn

Since the Maillard reaction is highly correlated with its precursor compounds, high intensity of BI in fermented seed means that fermentation process could generate Maillard reaction’s precursor compound such as reducing sugars and amino acids (Belitz and Grosch, 1999).. This is similar to the fermentation process of cocoa beans, where free amino acids, peptides and reducing sugar will be developed and act as precursors of Maillard non-enzymatic browning (Mohr et al., 1976)..

The enzyme α-amylase can catalyze the hydrolysis of internal α -1,4-glycosidic bond present in starch with the production of reducing sugars. In the study of substrate concentration on enzyme kinetics, the enzyme is kept constant where as the concentration of starch is taken in increasing order. As the substrate concentration increases, the amount of products produced in every successive. The intensity of colour depends on the concentration of reducing sugars produced.

GC-MS analysis of the methanolic extracts of Smilax china and Salix alba and their antioxidant activity

tailieu.vn

The compounds found in the methanolic extract of Salix alba were reducing sugars like D-allose (4.40%) and pyrogallol (10.48. Both MESC and MESA were found to contain different types of important chemical constituents, which were fatty acid esters, terpenes, high-molecular-weight hydrocarbons, and their oxygenated products. Fatty acids like cis-vaccenic acid and telfairic acid and esters are mainly observed in both plant extracts.

However, thiamin is very heat sensitive and is easily destroyed during feed processing, especially in the presence of reducing sugars. Dietary forms of riboflavin are mostly coenzyme derivatives that are released in the stomach and hydrolyzed by phosphatases in the small intestine. Riboflavin is absorbed by a specialized transport mechanism in the proximal small intestine. Intestinal absorption of riboflavin appears to be increased by the presence of food in the intestine.
