This study investigated the effects of microwave power density on effective moisture diffusion coefficient (Deff), glass transition temperature (Tg), gelatinization temperature (TP), physical and chemical qualities of lotus seeds during microwave vacuum drying. Deff increased by 42% and 127% at 15W/g and 20W/g, respectively, when compared with 10W/g. TP was(More)
Purple sweet potato starch is a potential resource for resistant starch production. The effects of heat-moisture treatment (HMT) and enzyme debranching combined heat-moisture treatment (EHMT) on the morphological, crystallinity and thermal properties of PSP starches were investigated. The results indicated that, after HMT or EHMT treatments, native starch(More)
Nelumbo nucifera Gaertn. has a relatively wide geographical distribution and biological diversity; various lotus parts have excellent food and medicinal values. Lotus seeds, which are currently the oldest known plant seeds, contain many functional ingredients. They can be eaten raw or cooked, and are often added to foods as ingredients or supplements. Many(More)
The bamboo shoot (Leleba oldhami Nakal) shell is a by-product during bamboo shoot processing. It is a cheap and available resource for dietary polysaccharides. Herein, a novel polysaccharide BSSP2a was isolated and characterized from the bamboo shoot shell polysaccharides, and it was identified as a homogeneous highly-branched beta type pyran polysaccharide(More)
Lotus is an edible and medicinal plant, and the extracts from its different parts exhibit various bioactivities. In the present study, the hot water-soluble polysaccharides from lotus seeds (LSPS) were evaluated for their cancer cell cytotoxicity, immunomodulatory and antitumor activities. LSPS showed significant inhibitory effects on the mouse gastric(More)
In this article, we describe a carbon nanotube (CNT)-based lateral flow biosensor (LFB) for rapid and sensitive detection of DNA sequence. Amine-modified DNA detection probe was covalently immobilized on the shortened multi-walled carbon nanotubes (MWCNTs) via diimide-activated amidation between the carboxyl groups on the CNT surface and amine groups on the(More)
Drying is the main process used to treat lotus seeds for storage. In this study, response surface methodology was used to optimize processing methods for microwave vacuum (MWV) drying of lotus seeds and to create a desirable product. A central composite design with three important factors: microwave output power (2.0-4.0 kW), vacuum degree (-0.070 to -0.090(More)
In the bamboo shoot processing industries, bamboo shoot shells are discarded without any utilization. As a cheap potential dietary fibers resource, bamboo shoot (Leleba oldhami Nakal) shell was decomposed to dietary fibers by multiple enzymes. The extraction yields of insoluble dietary fiber and soluble dietary fiber were 56.21% and 8.67%, respectively. The(More)
The 1st International Symposium on Phytochemicals in Medicine and Food (ISPMF 2015) was held in Shanghai, China, from June 26th to 29th, 2015. The 1st ISPMF was organized by the Phytochemical Society of Europe (PSE) and the Phytochemical Society of Asia (PSA). More than 270 scientists from 48 countries attended this meeting. The program of ISPMF 2015(More)
Lotus seeds were identified by the Ministry of Public Health of China as both food and medicine. One general function of lotus seeds is to improve intestinal health. However, to date, studies evaluating the relationship between bioactive compounds in lotus seeds and the physiological activity of the intestine are limited. In the present study, by using(More)
