Physicochemical composition of pure and adulterated royal jelly

Abstract: The physicochemical composition of pure royal jelly as well as of some adulterated samples was analyzed by determining moisture, ash, lipids, nitrogen/proteins, carbohydrates, starch and 10- HDA (10-hydroxy-2-decenoic acid). The solubility in alkaline medium was used to detect the main frauds for adulterating royal jelly which comprise addition of yogurt, water, egg white, sweet condensed milk mixed with propolis, unripe banana and corn starch slurry

“…Other authors also found differences (HAYDAK, 1970;PALMA, 1992;SCHMIDT;BUCHMANN, 1992;LERCKER et al, 1993;SCHMITZOVA et al, 1998;PARFITT, 1999;GARCIA-AMOEDO;ALMEIDA-MURADIAN, 2007) and attributed these differences to the nutritional status of the evaluated colonies, age of mother queens, and the laboratory methods used to analyze their components. Queiroz, Barbosa and Azevedo (2001) reported that supplementation is good, mainly in the Northeast region of Brazil, for royal jelly production throughout the year, including autumn and winter, periods between flowering, in regions of monoculture such as sugarcane plantation, limited pollen flow or low nutritional pollen quality.…”

“…reviews: Ramadan and Al-Ghamdi 2012). The content of moisture (Sabatini et al 2009), carbohydrates (Asencot and Lensky 1988;Lercker et al 1992), proteins (Simúth 2001;Boselli et al 2003;GarciaAmoedo and Almeida-Muradian 2007), lipids (Lercker et al 1992;Noda et al 2005), 10-HDA (Bloodworth et al 1994;Koshio and de AlmeidaMuradian 2003;Pamplona et al 2004) and minerals (Benfenati et al 1986;Stocker et al 2005;Garcia-Amoedo and Almeida-Muradian 2007) has been thoroughly documented. However, it is important to note that almost all of these studies were focused on the quality of commercial RJ (i.e., the food of 4-day-old queen larvae).…”

“…The viscosity of royal jelly varies with the age of honeybees and water content. Royal jelly is widely known for its complex composition, including various minerals, proteins, amino acids, steroids, phenols, carbohydrates, vitamins, lipids, and other, as yet, unidentified substances (Garcia-Amoedo and Almeida-Muradian, 2007).…”
