In a broad sense, the name coffee is used not only for fruits of the coffee tree (cherry coffee), but also for processed fruit such as green (raw) coffee, roasted coffee, instant coffee, and coffee as a beverage. The grading and quality evaluation of coffee beans is based on uniformity, purity, the absence of damaged beans, and decisively on the organoleptic properties of the beverage prepared ...

The effect of boiling and roasting on the lipid quality, proximate composition, and mineral content of African walnut seeds (Tetracarpidium conophorum) was assessed. Results indicated that the quality of walnut oil significantly (p < .05) reduces with the treatments. Oils extracted from DBWN 60 min (Dried and boiled walnuts 60 min) and FBWN 60 min (Boiled fresh walnuts 60 min) were the most alt...

The present study aimed to identify the most important packaging attributes for purchasing a product not currently on the Brazilian market: antioxidant-rich instant coffee, a blend of roasted coffee and green coffee. Five package types of the same brand of instant antioxidant-rich coffee marketed in different countries were evaluated through a focus group. The attributes’ glass shape, glass lid...

A sensitive and reliable LC-(ESI)MS/MS method was developed and validated for the simultaneous analysis of five common advanced glycation endproducts (AGEs) after enzymatic digestion in raw and roasted almonds. AGEs included carboxymethyl-lysine (CML), carboxyethyl-lysine (CEL), pyralline (Pyr), argpyrimidine (Arg-p), and pentosidine (Pento-s). This method allows accurate quantitation of free a...

BACKGROUND Nuts are one of the main consumed snacks worldwide and a significant component of Iranian's diet. Natural contamination of nuts with fungus is unavoidable and is a major challenge to nuts safety and quality. OBJECTIVES The purpose of this research was to study fungal contamination in commercially available nuts (pistachios, walnuts and peanuts) in the markets of Tabriz, Iran. MAT...

One hundred and seven Limousin or Charolais crossbred steers averaging 234.58 kilograms each were randomly assigned to one of three diets. The first diet contained a commercial supplement to increase the ration's protein level. The second group received a diet fortified with flaked roasted soybeans. The third group was fed a diet containing whole roasted soybeans as a supplemental protein sourc...

In this work, the potential of mid-infrared diffuse reflectance spectroscopy with Fourier transform for discrimination of 29 commercial Brazilian coffee samples with different industrial processing, i.e., caffeine extraction and roasting degree, was evaluated. The statistical treatments applied to pretreated spectral data were principal component analysis and partial least squares – discriminan...
