Introduction:

When it comes to preserving food and prolonging its shelf life, vacuum packaging machines have proven to be an invaluable tool. By eliminating air from the package, these machines help create a vacuum, preventing the growth of bacteria, yeast, and molds, thereby extending the freshness of food. This article examines the significance of vacuum packaging machines and their impact on food preservation.

The Benefits of Vacuum Packaging:

1. Extended Shelf Life: Vacuum packaging machines ensure longer shelf life for perishable goods. By eliminating oxygen, the primary factor responsible for oxidative deterioration, the growth of spoilage-causing microorganisms slows down, significantly increasing the product's longevity.

2. Enhanced Food Safety: Vacuum packaging removes air, reducing the risk of bacterial contamination. This method creates a sealed, airtight environment, inhibiting the growth of harmful bacteria such as Salmonella and Listeria, which thrive in oxygen-rich environments, thus minimizing the chances of foodborne illnesses.

3. Retained Freshness and Flavor: The removal of oxygen from the package prevents the oxidation process, preserving the natural color, texture, and taste of the food. Vacuum packaging helps maintain the sensory attributes of food for an extended period, ensuring that consumers enjoy the product in its original form.

4. Prevents Freezer Burn: Freezer burn occurs when the surface of frozen food becomes dehydrated and develops into unappetizing, discolored patches due to exposure to air. Vacuum packaging eliminates air contact, preventing moisture loss and the formation of ice crystals, thereby avoiding freezer burn.

5. Cost Reduction: Vacuum packaging can help reduce food waste and save money. By prolonging the shelf life of perishable goods, businesses can minimize product spoilage, decrease restocking frequency, and enhance overall inventory management.

Types of Vacuum Packaging Machines:

1. Chamber Vacuum Sealers: These machines are suitable for high-volume food packaging. They work by placing the product within a vacuum-sealed chamber, removing the air, and then sealing the package. Chamber vacuum sealers are ideal for sealing liquids, powders, and fragile items.

2. External Vacuum Sealers: Designed for small to medium-scale operations, these machines are compact and portable. They use a bag to create a vacuum by drawing out the air from the package, before sealing it with a heat strip. External vacuum sealers are commonly used in homes, restaurants, and small businesses.

Conclusion:

Vacuum packaging machines have become an integral part of food preservation, offering numerous benefits such as extended shelf life, improved food safety, retained freshness and flavor, prevention of freezer burn, and cost reduction. Businesses and consumers can rely on these machines to ensure food products stay fresh and safe for an extended period, thus minimizing food waste and enhancing overall food quality and satisfaction.

醫師提醒過早服用補腎轉骨藥方可能導致性早熟，建議家長找及格的中醫師辨證後再進行開藥，切勿自行采辦來路不明的轉骨方。（圖片來曆／freepik）

這些案例都是小兒遺傳內分泌科主治醫師蔡立平於發展門診經具體評估並賜與適當醫治後的成果。

為了增進兒童發展，而今市情上常常看到轉骨方的告白。對此，台北市立結合病院和平婦幼院區中醫科主治醫師蔡佩怡指出，轉骨方藥通常以補腎為主，但藥材可能過於溫燥，其實不必然合適每一個人。過早服用補腎轉骨藥方可能導致性早熟，因此建議家長前往醫院或診所，由及格的中醫師辨證後再進行開藥，切勿自行購置來路不明的轉骨方。

蔡佩怡進一步指出，中醫調治長高雖以補脾腎為主，但仍須依個人體質辨證論治，隨證加減，如青少年在青春期多處於課業壓力大的期間，是以可酌加疏肝解鬱的中藥，假如是自己胃口欠安的孩童，則可酌加山查、麥芽等開胃健脾藥方。

從營養學角度來看，營養不足對於兒童發展有曆久影響。憑據106年至109年國民營養健康狀態變遷調查，7-18歲體重太輕者百分比為6.6-12.6%。厭食、食慾不振、偏挑食或微量元素缺少等身分所產生的營養不足問題，會導致孩子身材矮小、認知成長緩慢等狀態。另外一方面，兒童及青少年有肥胖或太重問題者約占1/3生齒。除少部份由於基因影響，環境及生活習慣亦為肥胖成因。高熱量低營養的食品取得輕易且廉價，3C產品流行，運動量削減，構成致胖情況（obesogenic environment），加上肥胖易致使性早熟，骨板提早癒合也就導致發展發育異常。

有鑑於此，在這個少子化的年月，更要提升下一代優質成長。臺北市立結合醫院自113年1月31日起，每周三下晝於和平院區開啟「兒童發展發育結合門診」，由資深小兒遺傳內排泄蔡立平副傳授醫師、蔡佩怡中醫師及黃彥綾營養師共同開診，由中西醫共同診治，不但可以依分歧體質及診斷追求恰當科學性的醫治，同時也可藉由結合門診的情勢，節省就診所需的時候，克日起開放網路預約，迎接有成長發育需求的民眾多多哄騙。
