Scales and balances are necessary tools in all aspects of the food cycle – during harvest, processing, packaging, service, and sales. Purchasing weighing equipment for food-related applications can be a daunting task, but with proper information, it can be easy as pie.

What are food scales?

Food scales are specifically used to weigh products such as meat, vegetables or fruit. They are typically used to ensure portion uniformity in food outlets, restaurants and kitchens, as well as for personal calorie-counting in the home.

Types of food weighing scale

There are many types of food scale to buy — from easy-to-use digital kitchen scales to scientific food testing equipment such as moisture analysers. Most food scales fall into one of four categories: retail, testing, production and personal.

What are food scales used for?

Retail food measurement

Scales are used to weigh food products in many types of businesses, including restaurants, grocery stores and candy shops. They can measure produce at farm stands, weigh lunch meat at a delicatessen, or verify quantities of ingredients mixed into a batch of cookie dough at a bakery. Checkweighing scales are helpful for catering operations, as they help ensure uniform portion sizes. Approved food scales are required when selling food by weight commercially. 

Food testing labs

Moisture and weight assessments of food provide critical information about content, quality and safety. The levels of acidity and water, along with the absence or presence of bacteria, molds, pathogens and other contaminants, can be determined by analysing food samples. Food testing labs rely on highly specialised, scientific weighing devices. Moisture analysers use heated halogen lamps and loss-on-drying (LOD) methods to accurately establish moisture readings for products before dispatch. In research and development, weighing equipment is critical for maintaining sample integrity.

Food Testing

Food production

When food products enter the processing phase, scales, balances and moisture analysers facilitate quality control. They can help to ensure freshness and quality of the product during packaging, and aid in determining proper expiration dates. Scales used in food production are specifically designed for larger, processing applications in industrial environments. Heavy-duty platform floor scales have higher weighing capacities and can be used to weigh large containers of produce such as potatoes without the need for excessive lifting. Usually constructed of stainless steel, washdown scales are sealed to protect against the intrusion of moisture, dirt or food particles. They can be cleaned easily and hosed down frequently during use to adhere to hygiene standards.

Home use

Personal food scales generally include digital kitchen scales. They usually are small, compact and easy to use for individual portion control or measuring baked goods in the home.

Why use a food scale?

Using a food scale will vary in importance depending on the type of scale and how you intend to use it. A food scale for personal use is more likely to be used recreationally and is therefore unlikely to be as regularly as a food scale for industrial use. Furthermore, trade approved food scales are required for selling produce and other good by weight and every business needs to ensure they are weighing food in accordance with legislation. For more information on EC trade approvals within the food industry and general food law, please visit the FSA (Food Standards Agency).

Standardisation

Trade-approved food scales are required when selling products that have been weight-specified. For example, if you order an 8oz steak in a pub, you expect to get 8oz of meat. Standardisation is not only trade-required, but also has a positive effect on customer satisfaction.

A take-away or catering business can save money by standardising portion sizes. For a take-away pizza business, measuring ingredients instead of approximating them helps ensure the pizza has the same flavour, appearance and taste every time. It also can minimise the amount of wasted food, which can help keep costs under control. Wedding caterers can use scales that offer counting features to verify the number of servings before placing into chilled storage.

Healthy living

Food scales can be used to maintain a healthy lifestyle through portion control. By weighing food portion sizes in grams, users can calculate an accurate calorie count, which can be used to control and maintain food intake on a daily basis.

How to use a food scale for calorie counting: Top tips

  1. Make sure your scale is set to the correct weight increment (grams, kilograms, ounces, etc).
  2. Verify that the scale has been zeroed/ tared.
  3. Remove packaging and non-edible parts from the food. (if you are weighing grapes, discard the vine, etc.)
  4. Place the product on the scale.
  5. Ensure that the product weighs as close to the portion size listed on the package as possible. (for example, a slice of bread should weigh 30g, so the value on the scale should be as close to 30g as possible)
  6. Once you approve the value, use a calorie counter to see how many calories are in a serving (how many calories are in a 100g serving of pasta)

How to find the best digital food scale for your needs

When you’re shopping for a digital food scale, you need to think about how you will be using the product. If you work in the food testing industry, you may require a high precision scientific scale such as an analytical or precision balance for recording accurate test results. If you are selling food by weight at a market stall, you will need trade-approved food scales in order to do so. If your scale is for personal use, an easy-to-use, convenient compact scale or kitchen scale may be suitable.
