The present single-dose study was performed to assess the effect of whole coffee fruit concentrate powder (WCFC), green coffee caffeine powder (N677), grape seed extract powder (N31) and green coffee bean extract powder (N625) on blood levels of brain-derived neurotrophic factor (BDNF). Randomly assorted groups of fasted subjects consumed a single, 100mg dose of each material. Plasma samples we...

Fermented foods such as Japanese traditional food "miso (fermented soy bean paste)" have been shown to be rich source of micronutrients with the potential to prevent various human diseases. We have introduced effects of a new dietary supplement of fermented grain foods mixture containing extracts from wheat germ, soybeans, rice bran, tear grass, sesame, wheat, citrus lemon, green tea, green lea...

Kopi robusta adalah salah satu jenis kopi yang banyak dibudidayakan di Indonesia. Salah proses dapat menentukan kualitas roasting. Tingkatan roasting biji diklasifikasikan menjadi light, medium dan dark. Penelitian ini bertujuan untuk mengetahui pengaruh terhadap kadar kafein dalam berasal dari Temanggung. Biji dianalisis secara organoleptis, pH ukur densitasnya. Seduhan serbuk diekstraksi cair...

1 Many plant species respond to herbivory with increased emission of volatile organic compounds (VOCs): these attract carnivorous arthropods and thereby function as an indirect defence mechanism. Whether neighbouring plants can ‘eavesdrop’ on such airborne cues and tailor their defences accordingly, remains controversial. 2 We used Lima bean plants ( Phaseolus lunatus ) to investigate whether h...

The quality of coffee green beans is generally evaluated by the sensory cupping test, rather than by chemical compound-based criteria. In this study, we examined the relationship between metabolites and cupping scores for 36 varieties of beans, using a nontargeted LC-MS-based metabolic profiling technique. The cupping score was precisely predicted with the metabolic information measured using L...

A novel strategy termed habitat-inducible rescue of survival (HIRS) was developed to identify genes of Pseudomonas syringae that are induced during growth on bean leaves. This strategy is based on the complementation of metXW, two cotranscribed genes that are necessary for methionine biosynthesis and required for survival of P. syringae on bean leaves exposed to conditions of low humidity. We c...

Effects of two blanching conditions using peroxidase (POD) and lipoxygenase (LOX) as indicator enzyme on residual enzyme activities, ascorbic acid and chlorophyll content in green beans during frozen storage were studied. No reactivation of both LOX and POD enzyme was observed during storage. The losses of ascorbic acid and chlorophylls during storage followed first order kinetics. Half-life of...

The leaf colonization strategies of two bacterial strains were investigated. The foliar pathogen Pseudomonas syringae pv. syringae strain B728a and the nonpathogen Pantoea agglomerans strain BRT98 were marked with a green fluorescent protein, and surface (epiphytic) and subsurface (endophytic) sites of bean and maize leaves in the laboratory and the field were monitored to see if populations of...

The crop nutrition has a well-defined effect on yield and quality of forage crops. Among various essential macro nutrients, the nitrogen has a key function in improving forage yield and crude protein contents but demand of crop for nitrogen varies with the cultivars. The present study was conducted to investigate the effect of different nitrogen levels (0, 25, 50 kg ha) on forage yield and qual...

Phenolic acids have been identified in a variety of legumes including lima bean, broad bean, common bean, pea, jack bean, goa bean, adzuki bean, hyacinth bean, chicking vetch, garbanzo bean, dral, cow bean, rice bean, mung bean and soybean. The present study was carried out with the following aims: (1) to identify and quantify the individual phenolic acid and determine the total phenolic conten...
