Heating and Defrosting Time Charts

microwave basics

Fundamental principles determine the success of microwave food preparation.

They include:

1.TEMPERATURE OF FOODS Frozen or refrigerated food items will require longer heating times to reach a desired serving temperature than foods from room temperature.

2.FOOD COMPONENTS Foods high in sugar, salt, fats and moisture content heat faster because these properties attract microwave energy. Denser foods high in protein and fiber, absorb microwave energy slower which means a lengthier heating time.

3.BULK/VOLUME – The greater the mass of food, the longer it takes to heat.

4.CONTAINERS Ceramic, paper, china, styrofoam, glass and plastic are suitable for use in microwave ovens with the following caution.

DO NOT HEAT foods in a SHIELD container or

Heating foods with either high sugar or high fat content should be done. ONLY in high temperature-resistant containers since these foods get very hot. Using styrofoam containers for these foods will cause the styrofoam to warp. Other low temperature restaurant glass or plastic platters may crack or wrap under similar conditions.

bag. Foods expand when heated and can break the container or bag.

5.AVOID METAL because it “bounces” the microwaves, causing uneven heating and sometimes even flashes, which may pit or mar the interior of the oven, the metal container or plate trim.

6.Heated liquids can erupt if not mixed with air. Do not heat liquids in your microwave oven without first stirring.

HEATING FOODS FROM REFRIGERATED TEMPERATURE

Foods stored in the refrigerator (40˚F) should be covered before reheating with the exception of breads, pastries or any breaded product, which should be heated uncovered to prevent sogginess.

Most conventionally prepared foods should be slightly undercooked, and held in the refrigerator, so that overcooking does not occur during microwave heating.

Cooked items, such as vegetables, may be portion plated and covered for reheating without loss of color, texture or nutritional content.

HEATING FOODS FROM ROOM TEMPERATURE Food items such as canned entree, vegetables, etc. will require significantly less heating time than those from refrigerated temperatures.

IMPORTANT RECOMMENDATIONS

1.For best results it is recommended that foods conventionally prepared be slightly undercooked when subsequently heated in this oven.

2.REMEMBER that after the heating cycle has been completed, internal food temperatures continue to rise slightly in foods heated in this oven.

3.A major abuse of microwave applications is the category of breads, pastries and pies are drier than insides or fillings, they heat more slowly. Therefore, baked goods should ONLY be heated until the crust is warm to the touch (120˚F-130˚F).

4.DO NOT OVERHEAT YOUR FOOD: 99% of all food quantity complaints of microwave heated foods can be traced to overheating.

Panasonic NE1257R, NE2157R, NE1757R, NE1258R Microwave basics, General guidelines for heating in a national microwave oven

NE1257R, NE1258R, NE1757R, NE2157R specifications

Panasonic has long been a trusted name in the realm of commercial microwaves, and their models NE1258R, NE1757R, NE2157R, and NE1257R are outstanding examples of innovation, efficiency, and reliability. These microwaves are designed for heavy commercial use, suitable for restaurants, cafes, and convenience stores, where speed and consistency are essential.

The Panasonic NE1258R is equipped with a powerful 1000 watts of cooking power. Its compact size makes it ideal for kitchens with limited space, while its easy-to-use control panel ensures quick operation. One of its standout features is the patented inverter technology, which allows for consistent heating and cooking throughout, minimizing the risk of hot or cold spots in food. This technology enhances the overall quality of food being prepared, making it a favorite among chefs who prioritize precision.

Moving up in size and power, the NE1757R and NE2157R models boast 1750 watts and 2100 watts, respectively. This additional power allows for faster cooking times, ideal for busy environments that demand efficiency. Both models also feature extensive auto-cook programs, facilitating a wide variety of menu options with just the press of a button. The user-friendly interface paired with digital display makes cooking straightforward and reduces the potential for errors.

Another common feature among these models is their robust safety design. For instance, all four models come equipped with a safety interlock system, ensuring that the microwave can only operate when the door is securely closed. Furthermore, a cool-touch door and exterior minimize the risk of burns, making these units safe for staff in a bustling kitchen.

Durability is also a key characteristic. Each model is constructed from high-quality stainless steel, which not only provides a sleek appearance but also resists corrosion and is easy to clean. This design consideration is especially crucial in commercial settings where hygiene and maintenance are paramount.

In conclusion, Panasonic’s NE1258R, NE1757R, NE2157R, and NE1257R models represent a blend of technological advancement and user-centric design. Their high power, inverter technology, robust safety features, and durable construction make them ideal choices for any commercial kitchen looking to enhance efficiency and food quality. These microwaves stand out as powerful tools in the culinary industry, helping operators meet the fast-paced demands of modern food service.
