Which of the following is considered a minimally processed food?
Fresh fruits and vegetables
Canned soup
Microwave meal
Packaged snack cake
Fresh fruits and vegetables are usually washed and trimmed but not chemically altered, preserving their nutrients and natural state. Canned soup, microwave meals, and snack cakes undergo additional processing steps like cooking and additives.
What additive is commonly used to preserve freshness in packaged bread?
Monosodium glutamate
Aspartame
Xanthan gum
Calcium propionate
Calcium propionate inhibits mold growth in baked goods, extending shelf life without affecting taste. Other options serve as flavor enhancers, sweeteners, or thickeners rather than preservatives.
Which ingredient indicates added sugar content in a packaged product?
High fructose corn syrup
Made with whole grains
Low sodium
Enriched flour
High fructose corn syrup is a sweetener derived from corn and is a common source of added sugars. Claims like "made with whole grains" or "low sodium" refer to other nutritional aspects, not sugar content.
Preservatives are added to processed foods primarily to:
Add nutritional value
Enhance flavor
Extend shelf life
Improve texture
Preservatives inhibit microbial growth, keeping foods safe and fresh longer. Flavor enhancement, texture improvement, and nutritional fortification are separate processing goals.
Which processing method removes water to inhibit microbial growth?
Pasteurization
Fermentation
Dehydration
Emulsification
Dehydration reduces moisture content, preventing spoilage by microbes. Pasteurization uses heat, fermentation employs microorganisms, and emulsification mixes liquids.
Which nutritional effect is most common in highly processed foods?
Increased fiber
High vitamin C
High sodium content
Low fat
Processed foods often contain added salt for flavor and preservation, leading to higher sodium levels. They typically have reduced fiber and variable vitamin or fat content depending on the product.
Which ingredient is used as an emulsifier in margarine?
Nitrates
Sulfur dioxide
Transglutaminase
Lecithin
Lecithin helps oil and water mix uniformly in margarine, stabilizing the spread. Sulfur dioxide is a preservative, nitrates cure meats, and transglutaminase binds proteins.
If sugar appears listed three times under different names, what does this indicate?
Total sugar is low
There is a labeling error
Multiple forms of sugar are added
Sugars are naturally occurring
Manufacturers list various sweeteners (e.g., dextrose, sucrose) separately to achieve desired texture and sweetness. This practice increases actual added sugar rather than reflecting a labeling mistake.
As a best practice for selecting minimally processed options, you should choose foods with:
A single-ingredient list
Artificial colors
Hydrogenated oils
A long ingredient list
Foods listing only one ingredient are least processed and easier to assess for nutritional quality. Long lists with additives, colors, or hydrogenated oils indicate greater processing.
Which method uses pressure to preserve food without high temperatures?
Canning
Ultrafiltration
Freeze-drying
High-pressure processing
High-pressure processing inactivates microbes under extreme pressure, preserving nutrients and flavor. Canning and freeze-drying use heat or dehydration, while ultrafiltration is a liquid separation technique.
Which preservative in cured meats can form nitrosamines during cooking?
Nitrates
Sugar
Citric acid
Salt
Nitrates (and nitrites) can react with amino compounds in meats at high temperatures to form nitrosamines, which are linked to health risks. Salt and citric acid do not produce these compounds.
On a label, which term indicates the presence of hydrogenated oils?
Partially hydrogenated
Refined oil
Trans-fat free
Unrefined oil
'Partially hydrogenated' denotes oils that have been chemically altered, creating trans fats. 'Trans-fat free' and 'unrefined oil' signal the absence of hydrogenation.
Ultraprocessing grains typically leads to:
Lower calorie density
Increased glycemic index
Higher fiber content
Enhanced protein quality
Refining grains removes fiber and complex carbohydrates, causing faster digestion and blood sugar spikes, thus raising the glycemic index. Fiber and protein are generally reduced, not improved.
Monosodium glutamate (MSG) is primarily added to processed foods to:
Thicken sauces
Enhance umami flavor
Sweeten the product
Preserve freshness
MSG intensifies the savory, umami taste in foods. It does not function as a preservative, sweetener, or thickening agent.
Which practice reduces acrylamide formation in fried snacks?
Adding salt to the batter
Increasing frying duration
Using recycled oil
Lowering frying temperature
Acrylamide forms more rapidly at higher temperatures when frying starchy foods. Lowering the cooking temperature slows the reaction, reducing acrylamide levels.
Which processing method retains the most nutrients in fruits and vegetables?
Dehydration
Canning
Flash freezing
Thermal pasteurization
Flash freezing rapidly lowers temperature, preventing large ice crystals and preserving cellular structure and nutrients. Canning and dehydration involve heat or water removal that can degrade some vitamins.
A consumer wants to avoid added phosphates. Which ingredient should they watch for on labels?
Calcium ascorbate
Citric acid
Malic acid
Sodium phosphate
Phosphates like sodium phosphate are used as emulsifiers and moisture retainers in processed foods. Citric and malic acids are organic acids, and calcium ascorbate is a vitamin C derivative, not a phosphate.
High-pressure processing compared to thermal pasteurization generally results in:
Longer processing times
Better retention of vitamins
Higher sodium levels
Greater protein denaturation
HPP inactivates microbes through pressure, minimizing heat exposure and preserving heat-sensitive vitamins. Thermal pasteurization often leads to some nutrient degradation.
Which additive serves as both an antioxidant and a color stabilizer in processed meats?
Calcium propionate
Xanthan gum
Sodium benzoate
Ascorbic acid
Ascorbic acid (vitamin C) prevents oxidation of myoglobin, maintaining meat color and scavenging free radicals. Sodium benzoate is a preservative, calcium propionate prevents mold, and xanthan gum thickens.
Which form of resistant starch is produced when cooked starches are cooled, enhancing gut fermentation?
Native starch (RS2)
Enzyme-resistant starch (RS5)
Retrograded starch (RS3)
Chemically modified starch (RS4)
Cooling cooked starch causes retrogradation, forming resistant starch type 3 that resists digestion and supports fermentation in the colon. Other types arise from raw granules, chemical modification, or enzyme treatments.
