Food preservation in modern kitchens is paramount, battling against spoilage and waste. The quest for extended freshness often leads home cooks and culinary enthusiasts to vacuum sealers, devices designed to extract air and seal food, drastically slowing down degradation. Among the myriad options, the Oliso Pro VS97A Smart Vacuum Sealer emerges as a notable contender, promising efficiency, convenience, and a smart approach to food storage. This review delves into its core functionalities, unique selling points, and overall performance to help you decide if this compact powerhouse is the right addition to your kitchen arsenal.
What is a Vacuum Sealer?
A vacuum sealer is a kitchen appliance that removes air from a food storage bag or container and then seals it, creating an airtight environment. The fundamental principle behind its operation is simple: by eliminating oxygen, vacuum sealers inhibit the growth of aerobic bacteria, molds, and yeasts, which are primary culprits in food spoilage. This process significantly extends the shelf life of various foods, from fresh produce and meats to pantry staples. While rudimentary methods of food preservation like salting and smoking have existed for centuries, modern vacuum sealing technology has evolved to offer a more convenient and effective solution for everyday use, becoming a staple in both home and professional kitchens.
Benefits of Using a Vacuum Sealer
Integrating a vacuum sealer into your routine offers a multitude of advantages, transforming how you manage food and reduce waste.
Extended Food Preservation
Table is empty.The most prominent benefit of vacuum sealing is its ability to prolong the freshness of food. By removing oxygen, the primary cause of spoilage, meats, vegetables, fruits, and even dry goods can stay fresh for weeks or even months longer than traditional storage methods. This means less food waste and more value from your grocery purchases.
Preventing Spoilage
Oxygen, along with moisture and warmth, creates an ideal environment for microorganisms to thrive. Vacuum sealing deprives these spoilage agents of oxygen, dramatically slowing down the growth of bacteria, yeasts, and molds. This not only keeps food safe to eat for longer but also prevents off-flavors and odors from developing.
Retaining Flavor and Nutrients
When food is exposed to air, it can suffer from freezer burn, dehydration, and oxidative damage, leading to a loss of flavor, texture, and nutritional value. Vacuum sealing locks in the natural juices, flavors, and vital nutrients, ensuring that your food tastes as good as when it was first prepared, even after prolonged storage. This is particularly beneficial for meal preppers and sous vide enthusiasts.
Maximizing Storage Space
Vacuum-sealed bags are compact and flexible, taking up significantly less space in your refrigerator, freezer, or pantry compared to bulky containers or loosely wrapped items. This efficient use of space allows for better organization and more storage capacity, which is especially valuable in smaller kitchens.
Diverse Applications in Home and Business
Beyond basic food storage, vacuum sealers offer versatility for various applications. They are indispensable for sous vide cooking, marinating foods quickly, and even protecting non-food items like important documents, silverware, or camping gear from moisture and air. In small businesses, they are crucial for portion control and extending the shelf life of products.
Types of Vacuum Sealers
Understanding the different types of vacuum sealers can help you appreciate where the Oliso Pro VS97A fits into the landscape of food preservation technology.
External Vacuum Sealers
These are the most common type for home use. They work by placing the open end of a specially designed bag into a sealing channel. The machine then sucks the air out of the bag and heat-seals it shut.
- Advantages: Generally more affordable, compact, and easy to use for dry goods and many moist foods. They are excellent for everyday food storage and meal prepping.
- Disadvantages: Can struggle with excessive liquids, as fluids can be drawn into the pump, potentially damaging the machine or preventing a good seal. Most require proprietary bags, which can be an ongoing expense.
Chamber Vacuum Sealers
Typically found in commercial settings, chamber sealers operate by placing the entire bag inside a chamber. The air is then removed from the entire chamber, equalizing the pressure inside and outside the bag, before the bag is sealed.
- Advantages: Superior for sealing liquids, soups, and delicate items without crushing them. Can use less expensive, smooth vacuum bags.
- Disadvantages: Significantly larger, heavier, and more expensive than external sealers, making them impractical for most home kitchens.
Handheld Vacuum Sealers
These small, battery-operated devices are designed for convenience and quick sealing. They typically work with specialized zipper-top bags or containers that have a port for air removal.
- Advantages: Extremely portable, space-saving, and often more affordable. Ideal for quick resealing of frequently accessed items or for travel.
- Disadvantages: Generally have less powerful suction than full-sized external sealers, and the seals may not be as robust or long-lasting. They rely on specific bag types that can also be costly.
The Oliso Pro VS97A Smart Vacuum Sealer, while compact, functions as an advanced external sealer. It distinguishes itself with smart features that address common external sealer challenges, particularly its impressive handling of moist foods.
Oliso Pro VS97A Smart Vacuum Sealer: A Deep Dive
The Oliso Pro VS97A is more than just a compact vacuum sealer; it’s a meticulously designed appliance that has garnered recognition for its innovative approach to food preservation.
Award-Winning Design and Compact Footprint
The Oliso Pro VS97A has earned accolades, including the prestigious Madrid Fusion culinary award, for its compact and eco-friendly design. Its small footprint, around 9″x 13″, is a significant advantage over many bulkier vacuum sealers, making it easy to store in a kitchen drawer or cabinet without consuming valuable counter space. This thoughtful design ensures that efficiency doesn’t come at the cost of kitchen real estate.
Patented Freshkeeper® Technology and Dual-Seal System
At the heart of the Oliso Pro VS97A is its patented Freshkeeper® Technology, which utilizes a dual-seal system to maximize food freshness. This technology is engineered to create a robust and reliable seal, ensuring that air is effectively removed and kept out. The seals created by the Oliso are consistently strong, a critical factor for long-term food preservation.
Smart Features for Effortless Use
The VS97A is designed for ease of use, making vacuum sealing a quick and simple process. It boasts “handsfree auto bag detection,” allowing for effortless operation. Users simply place the bag in the machine, and the sealer takes over. A standout feature is its “Dry” and “Moist” food settings.

Steps to Use Your Oliso Pro VS97A Correctly
- Prepare Your Food: Ensure food is appropriately sized for the bag and that there’s enough space (at least an inch) between the food and the bag’s zipper seal.
- Select Bag Size: Choose the appropriate VacSnap bag (quart or gallon size) for your needs.
- Load the Bag: Place your food into the VacSnap bag and zip it shut. Make sure the bag’s seal is clean and free of food debris for an optimal vacuum. The Oliso bags have specific arrows to guide placement.
- Insert into Sealer: Position the sealed bag into the Oliso Pro VS97A’s slot. The machine’s automatic bag detection will sense it.
- Choose Setting: Select either “Dry” or “Moist” mode based on the food content. The “Moist” setting is crucial for foods with liquids to prevent issues.
- Start Sealing: The machine will automatically begin to extract air and then seal the bag. Indicator lights will guide you through the process.
- Remove Bag: Once the process is complete, remove your vacuum-sealed bag.
Cleaning and Maintaining Your Machine Regularly
Regular cleaning is vital for any kitchen appliance. For the Oliso Pro VS97A, wipe down the exterior with a damp cloth. Pay attention to the sealing area and vacuum channel to ensure no food particles interfere with future seals. For the reusable VacSnap bags, thorough cleaning is essential. Wash them with warm, soapy water and allow them to air dry completely before reuse to avoid issues with sealing or hygiene.
Common Errors and Troubleshooting
- Bag Not Sealing Properly: Often due to food debris or moisture on the bag’s zip-top seal. Ensure the seal is perfectly clean and dry. Also, check that the bag is correctly inserted into the machine. If using a reusable bag, it might not be clean enough.
- Not Enough Air Removed: Ensure the bag is not overfilled. Check for any leaks in the bag itself or if the bag’s zipper is fully closed.
- Liquid Drawn into Machine: While the “Moist” setting helps, excessive liquid can still be an issue. Pre-freezing liquid-rich foods for a short period (15-20 minutes) can solidify surfaces and prevent this. Alternatively, place a paper towel at the top of the bag to absorb excess moisture before sealing.
- Machine Not Responding: Check the power connection. If the issue persists, consult the user manual for specific troubleshooting steps or contact Oliso customer support.
