This study evaluated transepithelial transport mechanisms of Ile-Gln-Pro (IQP) and Val-Glu-Pro (VEP), two ACE-inhibitory peptides derived from Spirulina platensis, using human intestinal Caco-2 cell monolayers. IQP and VEP were absorbed intact through Caco-2 cell monolayers with Papp values of 7.48 ± 0.58 × 10-6 and 5.05 ± 0.74 × 10-6 cm/s, respectively. The transport of IQP and VEP were affected neither by Gly-Pro nor by wortmannin, indicating that they were not PepT1-mediated and did not involve endocytosis...

3-Aminopropanamide (3-APA) is the direct precursor of acrylamide produced in the Maillard reaction between asparagine and reducing sugars. In this research, we found that 3-APA could reduce acrylamide by the formation of adducts between acrylamide and 3-APA via Michael addition. The effects of temperature, heating duration and 3-APA/acrylamide ratio on the reduction of acrylamide were investigated. Addition of 3-APA to acrylamide at a molar ratio of 5:3 at 160 °C for 20 min reduced acrylamide by up to 47.29%...

Our aim was to propose simple extraction process to obtain phospholipids along with yolk-derived vitamins and fats. Five extracts marked as ethanol/acetone, methanol-chloroform/acetone, hot ethanol, hexane, and cold ethanol were developed and compared. Extracts' compositions were analyzed in terms of phospholipid, polar and nonpolar fraction, cholesterol, carotenoids, and tocopherols content. Further, liposomes prepared from extracts were characterized. The highest extraction efficiency was achieved by a one-step hexane procedure...

In this study, 10 different sulfide flavor compounds commonly used as food additives were screened for antiquorum-sensing activity. Among these, diallyl disulfide (DADS) and methyl 2-methyl-3-furyl disulfide (MMFDS) were found to exert the strongest inhibition against violacein production in Chromobacterium violaceum 026, the tested biosensor strain. DADS and MMFDS also inhibited the growth of Hafnia alvei H4, yielding MIC values of 48 and 41.6 mM, respectively. In addition, DADS and MMFDS also inhibited the ability of H...

To establish a structure-activity relationship for procyanidins, we verified the cyto-protective effect of 13 grape seed procyanidins, ranging from monomers to trimers against H2 O2 -induced oxidative stress in PC-12 neuroblastoma cells. Our study demonstrated some procyanidins were able to significantly protect PC-12 cells from the H2 O2 -induced cytotoxicity suggesting they possess neuroprotective effects against oxidative stress. Procyanidins' protective effects against oxidative stress mainly depended on their polymerization degree in addition to their structural features...

Lactobacillus plantarum CQPC06 (LP-CQPC06) is a newly discovered lactic acid bacterial strain. Here, the beneficial effects of this strain on C57BL/6J mice with dextran sulfate sodium-induced colitis were investigated. LP-CQPC06 was more resistant to gastric acid and bile salts than L. delbrueckii subsp. bulgaricus (LB). In the DSS-induced colitis mouse model, LP-CQPC06 treatment decreased the colon weight/length ratio and increased the colon length as compared to untreated mice with DSS-induced colitis. LP-CQPC06 also reduced the serum levels of interleukin 8 (IL-8), IL-1, tumor necrosis factor alpha, and macrophage inflammatory protein-1 alpha, as well as reducing levels of myeloperoxidase (MPO) and nitric oxide (NO) in the colon tissues of mice with DSS-induced colitis...

Gamma irradiation (60 Co) in postharvest of common beans (Phaseolus vulgaris L.), has already proven beneficial, regarding the prolongation of shelf life and physical, chemical, and organoleptic aspects of grains. However, few prior studies have investigated the effect of gamma irradiation on the dissipation of pesticides in foods, especially insecticides in beans. This study aimed to evaluate the waste dissipation of two insecticides, imidacloprid and thiamethoxam, used in the cultivation of common bean, a variety of Carioca, using gamma irradiation...

Expansion characteristics of cornstarch-based extrudates incorporating fiber-rich food processing byproducts was explored. Waxy and regular cornstarch were used as the base materials with apple pomace and sugarcane bagasse incorporated at two addition levels (0%, 15%, and 30% w/w). Extrusions were conducted at three different screw speeds (150, 200, and 250 rpm) with other parameters optimized and kept constant. Apple pomace inclusion resulted in higher initial expansion index (4.23 to 5.60) and higher stable expansion index (2...

The roles of native and damaged starch (DS) during fermented pastry making were examined by increasing the level of DS in wheat flour by ball-milling and/or by including amylase in the recipe. Increased DS levels increase laminated dough strength presumably by making less water available for the gluten. This effect was partly overcome by amylase use. During baking, a reduced resistance of the dough to gas cell expansion, as a result of enzymatic starch hydrolysis, seems responsible for increased pastry lift and improved crumb structure...

Despite existent fortification initiatives in the Philippines, approximately 50% of the population still suffers from iron deficiency anemia (IDA), mainly in rural areas. Fortification of staple foods has been proved successful in China and Vietnam. Coconut spiced vinegar (SV) is an inexpensive, widely available, and culturally acceptable condiment in Filipino households; however, no technical evidence exists on its potential as fortification vehicle. This study aimed to physicochemically characterize and evaluate the consumer acceptability of SV fortified with ferrous sulfate (FS), ferrous fumarate (FF), or sodium iron ethylenediaminetetraacetate (NaFeEDTA) at 0...

We investigated the protective effects and possible mechanisms of Aplysin against alcohol-induced liver injury. Rats were given daily either alcohol only (alcohol model group; 8 to 12 mL/kg body weight), one of three doses of Aplysin (50, 100, or 150 mg/kg Aplysin) plus alcohol, or volume-matched saline. After 6 weeks, the effects of Aplysin were assessed in terms of changes in histology, biochemical indices, and DNA oxidative damage. Potential mechanisms were analyzed through measurements of lipid peroxidation, antioxidant defense systems, expression of cytochrome P450 2E1, and expression of apoptosis-related genes...

In order to mimic physical characteristics of solid fat, ethylcellulose (EC) was used as an oleogelator in ice creams made with high oleic sunflower oil (HOSO). The aim was to improve structure of ice cream made with fully liquid vegetable oil by inhibiting droplet coalescence and to enable a colloidal fat network by making the oil droplets solid-like. Two different methods for incorporating EC into emulsions were developed, both designed to involve high pressure homogenization of ice cream mixes as in traditional ice cream production...

High-quality DNA extracts are imperative for downstream applications in molecular identification. Most processed food products undergo heat treatments causing DNA degradation, which hampers application of DNA-based techniques for food authentication. Moreover, the presence of inhibitors in processed food products is also problematic, as inhibitors can impede the process of obtaining high qualities and quantities of DNA. Various approaches in DNA extraction and factors in structure and texture of various food matrices affecting DNA extraction are explained in this review...

Peanut skins are a low-value byproduct of the peanut processing industry. Following their removal during the preparation of common peanut products, they are either discarded or used as a minor component of animal feed. Studies have found peanuts skins to be rich in health promoting phenolic compounds and thus have potential as a functional food ingredient. The aim of this study was to evaluate a new product that included the encapsulated phenolic extract from peanut skins in a flavored coating for peanuts. The phenolic compounds were extracted from peanut skins and then encapsulated in 10...
