What is a smart bulb WiFi camera? The monitor, which looks like a light bulb, is commonly used for home security monitoring. The shape of the bulb is diverse, but it can not be separated from the combination of nuts. Directly connect the nut to achieve 24-hour continuous monitoring, power off free, 360 degree panoramic monitoring. Smart home bulb WiFi camera with night vision function can also see clear images in the dark night Bulb Camera,WiFi Mini Bulb Camera, Auto Tracking Bulb Camera ,Security CCTV Bulb Camera Shenzhen Fuvision Electronics Co., Ltd. , https://www.outdoorsolarcamera.com
What is the purpose of smart bulb WiFi camera?
1. The panoramic 360 degree VR monitor can monitor the whole room by installing a light bulb in one room. There is no dead angle and video can be viewed in multiple modes.
2. Smart bulb WiFi camera can be used for lighting. Even though it is a household monitor, its basic lighting functions are well protected. The voice control light on mode and the app manual light on mode are very convenient for operation.
3. Two way voice intercom function. The smart home bulb monitor has its own microphone, which can listen to and play audio. Through calling on the APP, wireless WiFi transmission is directly realized, and then played through the bulb microphone. Its role is to directly communicate with family members, and the other is to intimidate the invasion of illegal elements.
4. As a monitor, it is locally stored in the memory card, plus the backup protection of the cloud disk. Even if someone destroys the camera or even takes away the home surveillance camera, the smart home bulb WiFi camera can still view relevant videos in the cloud disk.
How to use the smart bulb WiFi camera?
Scan the QR code on the mobile phone to download the corresponding APP software, and search the corresponding software name in the app store on the iPhone.
Power on the WiFi camera of the smart home bulb, search for the WiFi hotspot signal sent by the bulb in the phone settings, and click Connect.
Open the mobile phone APP and search the camera online. This process is automatically completed. Just wait.
Configure the local WiFi name in the APP settings, fill in the password, and remote monitoring can be realized after the configuration is successful.
Application of food preservative calcium propionate in bread mold prevention
Calcium propionate is one of the most effective and widely used food preservatives, especially for bread. It belongs to the group of organic acids and has a mild acidic nature that helps inhibit mold growth without affecting the yeast activity in bread. Unlike other preservatives like benzoic acid or sorbic acid, calcium propionate is non-toxic and safe for consumption. In China, its use in bread production was not common in the past due to backward industry standards and lack of awareness. However, as living standards improved and demand for bread increased, the need for effective preservation became more critical.
In 1984, the National Bureau of Standards approved the use of calcium propionate in bread, setting a maximum limit of 0.314% according to GBl760-81. This regulation helped ensure that bread could be stored longer, especially during hot and humid seasons when mold growth is rapid. Without proper preservatives, bread would often become moldy within two days, leading to significant losses for bakeries. As a result, many factories reduced production or converted unsold bread into rusks.
To understand how calcium propionate works, several experiments were conducted. The first test involved standard sweet and salty bread without any preservatives. After 40 hours of storage, all samples showed signs of mold. When 0.2% calcium propionate was added, the storage time extended by 20 hours, reaching 60 hours. This demonstrated its effectiveness in delaying mold growth.
Further tests explored the impact of flour type and baking time. Results showed that the quality of flour had minimal effect on mold growth as long as gluten levels were within a normal range. However, longer baking times significantly reduced moisture content, thereby increasing shelf life. For instance, bread baked for a longer duration lasted longer before showing mold.
The amount of calcium propionate also played a key role. At 0.25%, the shelf life increased to about 72 hours, while at 0.30%, it reached over 80 hours—adding 1 to 2 days of freshness. Packaging also influenced results. Bread packed in ordinary bags showed an additional 1–2 days of shelf life compared to unpackaged samples, with some lasting up to four days.
Different packaging materials had varying effects. Low-quality bags allowed small gaps, which led to shorter shelf life, while high-quality bags provided better protection. In ideal conditions, bread could last up to 10 days, depending on climate and humidity.
Despite these benefits, calcium propionate cannot prevent mold entirely. It only slows down the process. Mold spores are present in the air, so hygiene during production, packaging, and storage is equally important. Proper equipment, clean environments, and trained staff are essential to maximize the effectiveness of preservatives.
In conclusion, calcium propionate is a safe and efficient solution for extending bread shelf life. Its use not only reduces waste but also ensures product safety and quality. With proper application and good hygiene practices, bakeries can maintain fresh, mold-free bread even in challenging weather conditions.
