What is moisture retaining in cooking?
Because sugar binds water, reactions that need water are delayed if sugar is present. Bread and cakes baked with syrup will be more moist and have a longer shelf life than products made with sugar. This is due to the fructose content of the syrup, because fructose binds more water than sugar.
What is moisture food?
Moisture in foods occurs in two forms: (1) water bound to ingredients in the food (proteins, salt, sugars), and (2) free or unbound water that is available for microbial growth. Water activity is a good predictor of food safety and of how long a food product will last on the shelf.
How will you prepare and cook the food so that nutrients are retained?
The three R’s for nutrient preservation are to reduce the amount of water used in cooking, reduce the cooking time and reduce the surface area of the food that is exposed. Waterless cooking, pressure cooking, steaming, stir-frying and microwaving are least destructive of nutrients. Frozen vegetables can be steamed.
How does moisture content affect food?
Moisture content influences the taste, texture, weight, appearance, and shelf life of foodstuffs. Even a slight deviation from a defined standard can adversely impact the physical properties of a food material. For example, substances which are too dry could affect the consistency of the end product.
How do you calculate moisture content in a food sample?
Theory Moisture % = weight loss *100 Weight of the sample Total solid % =100- moisture In oven drying methods, the sample is heated underspecified conditions, and the loss of weight is used to calculate the moisture content of the sample.
How do you measure moisture in baked goods?
Convection, Vacuum and Infrared Drying Moisture Analyzers are the most common methods for moisture analysis. In a convection oven, the original sample is placed in the oven at a specified temperature and time. Once the product has finished drying, the above equation is used to determine the moisture content.
How do you measure moisture in food?
Here are some of the methods for determining the moisture content of foods and beverages:
- Oven Drying. This is the standard against which other methods are compared.
- Microwaves.
- Karl Fisher Titration/Homogenization.
- Near-Infrared Spectrometry.
- Freezing-Point Depression/Cryoscopy.
How moisture content is determined?
A sample is weighed, and the weight is recorded. The amount of water is determined by subtracting the dry weight from the initial weight, and the moisture content is then calculated as the amount of water divided by the dry weight or total weight, depending on the reporting method.
What method of cooking retains the most nutrients?
Cooking methods that preserve nutrients
- #1: Steaming. Steaming is the gentlest and healthiest way to prepare food.
- #2: Grilling. Grilling lets you get maximum nutritional value from your vegetables and helps food retain its truest flavour.
- #3: Baking or roasting.
- #4: Sautéing.
- #5: Microwaving.
How can you retain nutrients when cooking meat fish and poultry?
These easy tips will keep unwanted fat and calories out of your meat, poultry, and fish:
- Always trim any fat you can see.
- Add fish to your diet.
- Let hidden fat drain away from meat.
- Choose healthy cooking methods.
- Look for healthy recipes that add flavor without fat and calories.
How do you determine moisture content in food?
Here are some of the methods for determining the moisture content of foods and beverages:
- Oven Drying. This is the standard against which other methods are compared.
- Microwaves.
- Karl Fisher Titration/Homogenization.
- Near-Infrared Spectrometry.
- Freezing-Point Depression/Cryoscopy.

How do you test for moisture in food?
There are many methods for determination of moisture content. The primary methods used are loss on drying and Karl Fischer titration. Loss on Drying. In this method, a wet sample is weighed on a balance, placed in an oven, and heated until the end of the drying period, i.e., until the sample reaches equilibrium.
Why is there water in meat and poultry?
Water in Meat and Poultry Products. Have you ever wondered why cooked meat reduces in size compared to the raw product? One of the reasons for the decrease in size is due to water lost in the cooking process. Meat naturally contains about 75% water, but can vary depending on the cut.
What is the relationship between cooking temperature and added flavors?
The added flavors that are incorporated with meat product are under strict legislation, along with the meat product. Higher cooking temperatures will amplify the moisture lost in the cooking product.
Why does meat get smaller when cooked?
One of the reasons for the decrease in size is due to water lost in the cooking process. Meat naturally contains about 75% water, but can vary depending on the cut.
How do you preserve food so it never spoils?
In order to be shelf stable, perishable food must be treated by heat and/or dried to destroy foodborne microorganisms that can cause illness or spoil food. Food can be packaged in sterile, airtight containers. All foods eventually spoil if not preserved.
