An evening of science: Food Science and Food Product Development


AYER — Groton-Dunstable Science, Technology, Engineering and Mathematics is pleased to be sponsoring the following an evening of science.

The event, “Food Science and Food Product Development” will be presented by Lisa Semle on Sept. 24 at Cains Foods, 114 East Main St., Ayer. Refreshments will be served at 6:30 p.m., and the presentation will be from 7 to 9 p.m.

Have you ever wondered what exactly goes into mayonnaise, salad dressing or any other commercially produced food you consume, why each ingredient is there, and how they are arrived at? Lisa will introduce the science and engineering tradeoffs behind food design, using examples from her own work. In addition to the talk, she will lead a tour of the Cains plant including the lab, quality control, research and development, and micro areas. Lisa will also describe career paths in her field, and there will be ample time for questions and informal discussion.

The talk is aimed at high-school and advanced middle- school students, and is free and open to the public. Note that this talk will be on site at the Cains plant in Ayer, not at the G-D Middle School as usual.

Lisa Semle has been the Technical Director at Cains Foods for over nine years. She previously worked at Kens Foods, Basic American Frozen Foods, Nabisco/Planters and Friendly’s Ice Cream. Lisa earned her masters and BS degrees in food science from the University of Rhode Island. She lives in Pepperell and has two children who are currently in college.
