Why are peaches canned in syrup?

Canned peaches are a popular canned fruit, often found on grocery store shelves in the fruit aisle. When you pick up a can of peaches, you’ll notice they are packed in a sweet, sugary liquid instead of water. This sweet liquid is called syrup, and it’s added for a few important reasons.

Quick Answers

– Syrup helps preserve the peaches, preventing spoilage and discoloration

– It gives the peaches a sweet flavor that consumers expect from canned peaches

– The sugary syrup replaces some of the juice that is lost from the peaches during canning

– It helps the cans meet the minimum drained weight standards set by the FDA

Why Not Water?

You may wonder why canners don’t just use water instead of sugary syrup. After all, water is better for you than added sugars. While it’s true that syrup isn’t the healthiest option, there are some practical reasons why the canning industry uses it instead of water:

Preservation

The sugary syrup helps prevent spoilage and mold growth. Peaches are naturally sweet, with around 9% sugar content. Submerging them in heavy syrup approximates that level, keeping the flavor intact and preventing spoilage during storage. The high sugar content allows canned peaches to be shelf-stable for 12-18 months.

Flavor

Consumers expect canned peaches to taste sweet and flavorful. If packed in plain water, the peaches would be relatively tasteless compared to their fresh counterparts. The syrup lends concentrated sweetness and peach flavor. Consumer research shows many people actually prefer the flavor of canned peaches over fresh.

Juice Retention

When peaches are heat processed for canning, a significant amount of the natural juice inside the peaches leaches out into the packing liquid. The syrup replaces this lost juice and helps the peaches retain moisture. If canned in water, the peaches would have a dry, deflated texture.

FDA Requirements

The FDA establishes minimum drained weight standards for canned fruits, which is the net weight of product not including syrup or water. Minimum drained weights help ensure consumers get plenty of usable peach content per can. With water packing, it would be difficult to consistently meet FDA targets. The syrup bulks up the weight.

Types of Peach Syrup

Not all canned peaches are packed in the same syrup. Manufacturers can choose from light, medium or heavy syrups, depending on the desired sweetness level. Here are the common peach syrup types:

Heavy Syrup

Heavy syrup contains the most sugar – about 44% sucrose. It delivers the sweetest flavor but also the most calories. Heavy syrup is best suited for peaches intended for desserts like peach pie or cobbler, where extra sweetness is desirable.

Light Syrup

Light syrup has the lowest sugar content at around 17% sucrose. It has a lighter, more subtle sweetness good for peaches meant as snacks or garnishes. The lighter syrup saves on calories compared to heavy.

Medium Syrup

At around 31% sucrose, medium syrup strikes a balance between sweet and subtle. It provides plenty of sweet peach flavor without going overboard on sugar content. Most canned peaches are packed in medium syrup.

Packing Process

Now that we know why syrup is used, let’s look at how peaches actually get packed in syrup:

Peach Harvesting

– Peaches are hand-picked or mechanically harvested when ripe but still firm.

– They are quickly sent to packing facilities to minimize time between harvest and processing.

Peach Selection

– Peaches are washed, sorted and graded based on quality, size and ripeness.

– Only sound, undamaged peaches continue down the production line.

Syrup Preparation

– Sugar and water are combined in large vats to make the desired syrup concentration.

– Other ingredients like citric acid or ascorbic acid may be added.

Filling & Exhausting

– Peaches are placed in cans, up to 9-10 halves per can.

– A hot syrup solution is poured over the peaches to fill the can.

– Cans are sealed and heat is applied to drive out excess air and create a vacuum seal.

Thermal Processing

– Canned peaches are heat treated using hot water or steam to kill microorganisms.

– Processing times vary from 20-45 minutes depending on the size of can.

– This heating also deactivates enzymes and stabilizes the pH.

Cooling, Labeling & Storage

– Cans are cooled down using chilled water sprays.

– They are labeled according to variety, size, syrup type and expiration date.

– Cans are palletized and stored in climate-controlled warehouses.

Quality Control

Canners implement strict quality control measures to ensure canned peaches are safe and high quality:

Grade Standards

USDA grade standards for canned peaches help ensure ideal flavor, texture, color and uniformity. Minimum quality peaches are labeled “Grade B” while top quality is “Grade A”. Most national brands only use Grade A fruit.

Sampling & Testing

Random sample cans are opened at intervals and evaluated. Syrup density, pH, vacuum level, drained weight and other metrics are tested. If standards are not met, corrections are made.

Metal Detectors

Cans pass through sensitive metal detectors before and after sealing to catch any accidental contamination. Even tiny fragments of metal could cause food safety issues or damage equipment.

Code Dating & Traceability

Each can is marked with a pack date and production codes. This allows tracing back through the process if any issues arise. Stock is rotated using first-in-first-out system.

Health & Safety Certifications

Many companies have their facilities audited and certified against GFSI food safety schemes like SQF or BRC to comply with retailer and regulations.

Nutrition

Here is how canned peaches in light syrup stack up nutrition-wise (1/2 cup drained peaches):

Calories 60
Fat 0 g
Sodium 0 mg
Carbs 15 g
Sugar 14 g
Protein 1 g

The main nutritional downside is the added sugar from the syrup. Rinsing the peaches before eating can remove some excess sugar. Overall, canned peaches can be a decent source of vitamin A and C, magnesium and copper.

Cost Effectiveness

Canning peaches in light syrup offers an affordable way to enjoy peaches year-round. The processing allows much cheaper mass production compared to fresh peaches. Shelf-stable canned peaches also reduce waste from perishable fresh fruit.

Some cost comparisons for reference:

– Canned peaches, $2.50 per 28 oz can

– Fresh peaches, $3.99 per lb

– Frozen peaches, $4 per 16 oz bag

Convenience

The convenience of canned fruit like peaches has made it a pantry staple for generations. Key advantages include:

– Long shelf life of 12-18 months

– Ready to eat after opening – no prep needed

– Easy storage without refrigeration before opening

– Lightweight and portable for lunches, picnics or travel

– Versatile for use in recipes, snacks, desserts and more

– Available year-round, not just seasonal like fresh

Downsides of Canned Fruit

While practical, canned peaches do have some downsides:

– Higher in added sugar and syrup calories than fresh

– Lower fiber content after peeling skin

– Can have softer texture than some fresh varieties

– Canning process destroys some heat-sensitive vitamins

– Metal cans have higher environmental impact than other packages

– Opened cans have shorter shelf life and need refrigeration

Canned vs. Frozen vs. Fresh Peaches

So how do canned peaches compare with frozen and fresh? Here’s a quick rundown:

Canned Peaches

– Take longer to prepare – need to open can and drain liquid

– Added sugar from syrup

– Texture not as firm as fresh

– Lower vitamin C content from heat processing

– Convenient, last over a year unopened

Frozen Peaches

– No added sugar or liquid

– Firm texture retained when frozen quickly

– More vitamin C retained than canned

– Last about 10-12 months in freezer

– Require thawing before use

Fresh Peaches

– No added ingredients, just wash and slice

– Superior flavor and texture

– Highest nutrition when eaten right after picking

– Highly perishable, last only 1-3 weeks

– Limited seasonal availability

Commercial Uses

In addition to retail sale, canned peaches have many uses commercially:
