After his rejection by the cosmetics industry because he was color-blind, Porcello joined Nabisco. When he was hired, Nabisco promised that he could eventually earn a salary of up to $12,000 per year if he was successful. He began his Nabisco career at the company's plant in
Fair Lawn, New Jersey. He later worked at Nabisco's corporate headquarters in
East Hanover, New Jersey. Porcello joined Nabisco's
research and development department, which develops new lines of snacks. He was considered one of the world's leading experts on
cocoa, which is used to make chocolate. He was given the title, "principal scientist," during his career at Nabisco. The Oreo cookie has been sold since 1912, but it was Porcello who invented the modern creme-filling (excluding the kosher and trans fat changes later on) for Oreos and Double Stuffed Oreos, which have extra filling. In total, Porcello held five patents related to his work on the Oreo. He also developed a
product line of Oreos enrobed in
white chocolate and
dark chocolate. Porcello found the particular type of chocolate which he used for chocolate-covered Oreos while attending a food industry trade show in
Europe. Aside from his work with the Oreo, Porcello developed other Nabisco snack products, including
SnackWells. His position required him to travel extensively in search of new potential products and ingredients. According to his son, Curtis, Porcello often brought new snacks home with him to see how his family liked or disliked the potential new products. Porcello was not a huge eater of Oreo cookies, preferring to eat the cookie without dunking it in
milk. ==Later life==
