Morphological and physicochemical characterization of starches isolated from chestnuts cultivated in different regions of China

Guo, Jiayue; Kong, Lingyan; Du, Bin; Xu, Baojun (2019-06-01)

This study was to compare the characteristics of 21 starches isolated from chestnuts produced in different regions in China, also to investigate their potential food applications. Starches were isolated from chestnuts under ...
Inclusion complex formation between high amylose corn starch and alkylresorcinols from rye bran

Gunenc, Aynur; Kong, Lingyan; Elias, Ryan J.; Ziegler, Gregory R. (2018-09-01)

The formation of high amylose corn starch (HACS)-alkylresorcinol (AR) inclusion complexes was demonstrated using HACS and a crude AR extract from rye bran, and was confirmed by complementary characterization techniques. ...
Starch-menthol inclusion complex: structure and release kinetics

Shi, Linfan; Hopfer, Helene; Ziegler, Gregory R.; Kong, Lingyan (2019-12)

Flavoring ingredients are often the most expensive ingredients in food formulations, and their stability and release behavior are significant factors for quality and acceptability of food products. Among flavoring compounds, ...
Lipphilization and molecular encapsulation of p-coumaric acid by amylose inclusion complex

Kong, Lingyan; Wang, Siqi; Zhao, Yu; Tan, Libo; Zhang, Jing; Du, Zhongyao; Zhang, Hao (2019-08)

p-Coumaric acid (CA) is a natural phenolic compound with a wide range of bioactivities, but its tendency to degrade during food processing and storage limits its application in functional foods. Forming amylose-guest ...

Kong, Lingyan; Ziegler, Gregory R. (2013-01)

Taking advantage of the gelation process of κ-carrageenan, we have developed a wet-spinning process to fabricate micro-scale fibers from κ-carrageenan. Effects of three important spinning parameters, i.e. coagulation bath ...
Inhibition of starch digestion by gallic acid and alkyl gallates

Gutierrez, Alyssa San Andres; Guo, Jiayue; Feng, Jiannan; Tan, Libo; Kong, Lingyan (2020-05)

As phenolic compounds, alkyl gallates may inhibit the activity of digestive enzymes for starch. Furthermore, their alkyl chains may facilitate starch inclusion complexation and results in an increased resistant starch (RS) ...
Fabrication of pure starch fibers by electrospinning

Kong, Lingyan; Ziegler, Gregory R. (2014-05)

Many efforts to spin starch fibers are reported in the patent and research literature. All reported spinning methods are dependent upon addition of non-starch components, e.g. other polymers, plasticizers or cross-linkers. ...
