Departments: Mini Menaces
It only takes an area the size of a person’s thumb to produce thousands and thousands of fruit flies. One adult female fruit fly can lay 15 to 20 eggs in a batch and as many as 500 batches in her two-week life cycle. A few fruit flies can quickly multiply into an infestation.
Departments: Planning Makes Perfect
In the last issue we talked about the types of food technology, contact surfaces, cleaning chemistry and procedures. This issue we address time, schedules and basic sanitation equipment. When planning your cleaning and sanitation routine, start by quantifying time available for this process, then schedule the work and determine the manpower you’ll require. I recommend using the five-step process below to achieve the most efficient and effective results. Map out the five-step procedure for each piece...
Departments: Go With the Flow
Customer perception of food quality depends not only on taste, but also on physical properties, one of which is commonly referred to as “flow behavior.” Consider the following examples. Ketchup must pour out of a squeeze bottle easily and coat the hot French fries without running off. Cream filling in a doughnut needs to hold in place when you bite into it and not squirt out. Salad dressing is better appreciated when it coats the lettuce and vegetables and doesn’t run off into the bottom...
Departments: Incoming Quality Control of Water
Today’s modern food processing industries are heavily reliant upon water as both an ingredient and as an integral part of their preparation and processing functions. While in some instances the water used is further processed and treated by the food manufacturer, in many cases this supply of water is obtained from local municipal sources and under goes no further monitoring or processing beyond what is done by the local utility that supplies it to the end users. Unfortunately, in most cases little or...
Departments: Bytes vs. Bugs
Recent outbreaks of E. coli O157:H7 in the northeast fast-food restaurant sector have caused much anxiety among private sector food and beverage processing and preparation centers and public health officials, but several technological developments are helping food manufacturers protect their products from bacterial contaminants.
Departments: The Reputation Drain
It is difficult to ignore the news headlines announcing risks and tragedies associated with the various microorganisms and illnesses threatening the food industry, including E.coli, Salmonella, Avian Flu and so on. In the past 20 years, one serious pathogen – Listeria monocytogenes – has been a major concern to the food industry. Of all the known foodborne pathogens, it has one of the highest mortality rates.
Departments: Infrared: An Effective HACCP Tool
The heat is definitely on for food service operators to reach and maintain tight food safety standards. HACCP programs are all about controlling and eliminating hazards, and food temperatures—when, where and how to take them safely—are at the heart of the program. Fortunately though, hot and cold temperature measurement has gotten easier, faster and safer over the last few years. Infrared technology, as well as more sophisticated infrared temperature measurement techniques, can make a big...
Departments: Glass Packaging a Clear Choice
For generations, glass packaging has been trusted to store food, beverages and medicines. Glass has the staying power as a pure, sustainable package that’s healthy for the consumer and the environment. Made from natural raw materials – sand, soda ash and limestone – glass is impermeable and nonporous, which protects its contents from degradation and tampering. In addition, glass is chemically inert, which guards contents from moisture and oxygen, and ensures that the freshness and flavor...
With the steady increase in poultry processing rates, there has been a corresponding increase in wastewater pollutant concentrations. Despite mechanical improvements in wastewater treatment, many poultry processors continue to pay unnecessarily high fees for municipal water discharges. Michigan Turkey Producers (Wyoming, Mich.), a $100 million annual processor, in conjunction with Lyco Manufacturing (Columbus, Wis.), has set up a patented, state-of-the-art screening system for its poultry wastewater...
Departments: Policing Polyphenols
A substantial research effort is being devoted to better understand the protection against various diseases that epidemiological studies have shown to be provided by certain fruits and vegetables. Researchers generally believe that this protection comes from the activity of antioxidant compounds, particularly polyphenols, found in abundance in many fruits and vegetables.
