This study utilized a feed-forward neural network model along with computer vision techniques to discriminate sweet red pepper products prepared by different methods such as freezing and pureeing. The differences among the fresh, frozen and pureed samples are investigated by studying their bio-crystallogram images. The dissimilarity in visually analyzed bio-crystallogram images are defined as t...

Essential oils, flavors, and spices constitute a large and heterogeneous group of substances to which humans are exposed. The essential oils are defined as a group of odorous principles soluble in alcohol and only to a limited extent in water. They consist of a mixture of esters, aldehydes, ketones, and terpenes. Relatively few members of this group of sub stances have been shown to cause cance...

The fine structure of plastids and carotenoid content of the pepper fruit (Capsicum annuum) were studied during the various stages of ripening. Red ripe fruits contained spindle-shaped chromoplasts which originated from leuco-chloroplasts. The bleaching herbicides amitrole and SAN 9789 inhibited the biosynthesis of total carotenoids and the development of typical spindle-shaped chromoplasts. Bo...

the aim of this study was to determine the optimum mixture ratios for composting separated cattle manure and pepper plant residues. five 127 liter laboratory-scale bioreactor were used to investigate of separated dairy manure addition on the composting process of greenhouse pepper plant residues. cattle manure is considerably rich in nitrogen. however, composting with cattle manure alone is not...

This study was conducted to investigate the physical and sensory properties of ice cream containing fermented pepper powder. Three ice cream formulas were manufactured: 1, control; 2, supplemented with 0.1% fermented pepper powder; and 3, supplemented with 0.2% fermented pepper powder. Formulas 2 and 3 had significantly higher viscosity and lower overrun than formula 1 (p<0.05). Additionally, i...

Red hot pepper is a plant that belongs to the Solanaceae family and is known as Capsicum annuum. Capsaicin is the active ingredient of cayenne pepper. Ghrelin is a hormone, which consists of polypeptide structure. Ghrelin also contributes to growth hormone secretion, energy balance, food intake and body weight regulator. The aim of this study was the localization and expression of ghrelin in th...

Evidence was found for two previously unreported, nonenzymatic reactions that affected texture retention in acidified red bell peppers. First, oxygen was found to cause rapid softening of the pepper tissue such that it lost at least 40% of the initial tissue firmness within 2 weeks after acidification. Second, sulfite added to the acidified peppers prevented the softening caused by oxygen. Comb...

Members of the botanical family Piperaceae were among the first cultivated plants1. Black pepper (Piper nigrum) and long pepper (Piper longum) are the best known species in this family and are probably among the most recognized spices in the world. Black pepper alone accounts for about 35% of the world’s total spice trade. In addition, black pepper and long pepper have been used medicinally for...
