Airport security rules vary depending on the country and airport, so it's always best to check with the relevant authorities before travelling. In general, food items such as sweets are allowed through airport security, but they may be subject to additional screening if they obstruct x-ray images or are considered suspicious. Liquids, including gels, creams, and pastes, are typically restricted to containers of 100ml or less and must be placed in a clear plastic bag. Some items, such as breast milk and baby food, are exempt from this restriction but must still be stored in transparent containers. It's also important to note that airport security staff have the final say on what is allowed through checkpoints, and items may be prohibited if they pose security concerns.

Liquids are allowed in hand luggage if they are less than 100ml
Liquids in hand luggage are subject to restrictions. At most airports, you can only take liquids in containers smaller than 100ml through security. This rule applies even if the container is not completely full. Some airports may allow containers holding up to 2 litres of liquid. Liquids must be stored in a separate, transparent, resealable plastic bag, which should hold no more than a litre and measure approximately 20cm x 20cm.
There are some exemptions to the 100ml rule. For example, you can carry duty-free liquids in secure, tamper-evident bags of more than 100ml in your carry-on bag if they were purchased internationally and you are travelling to the United States with a connecting flight. Additionally, breast milk can be carried in quantities greater than 100ml when travelling without an infant. Liquid medication that is required during the flight can also be carried in quantities exceeding 100ml, but only with documentary proof, such as a prescription.
It is important to note that airport security staff have the final say on whether an item is allowed through the checkpoint. They will not permit anything they consider dangerous, even if it is typically allowed in hand luggage. Food items and powders can obstruct x-ray images, so your bags may need to be manually checked by security. To minimise delays, you can place these items in your hold luggage instead.
While sweets were not specifically mentioned in my search results, as long as they are not liquids, they should be allowed through airport security. However, keep in mind that the final decision rests with the TSA officer.

Food items can obstruct x-ray images and may be mistaken for suspicious items
Food items are permitted in hand luggage, but they can obstruct X-ray images and may be mistaken for suspicious items. This may result in additional checks and delays at security. To minimise delays, it is recommended that food items be placed in hold luggage.
Food items such as meat, dairy, fish, and animal products, as well as fruits, vegetables, nuts, and seeds, are restricted from being brought into the UK. Bread, cakes, biscuits, sweets, chocolate, and pasta are among the items that are not restricted. Liquids, including gels, creams, and pastes, are allowed in hand luggage as long as they are in containers holding no more than 100ml and are carried in a single, resealable clear plastic bag.
Breast milk can be carried in hand luggage, even when not travelling with a baby, as long as it is stored in a transparent container or bag and does not exceed 2 litres. It cannot be frozen or stored in a flask. Powders purchased in duty-free may be carried if packaged in a security tamper-evident bag with a receipt.
It is important to note that individual hand baggage allowances can vary by airline and airport, so it is recommended to check with them before travelling. Additionally, there may be different rules for electronic items and liquids depending on the country of travel. Airport security staff have the final decision on whether an item is allowed through the checkpoint, and items may be subject to additional screening or prohibited if they trigger alarms, appear tampered with, or pose security concerns.

Countries outside the UK may have different rules on carrying liquids
While the UK has its own set of rules regarding liquids in hand luggage, other countries may have different regulations in place. It's important to be aware of these variations to ensure a smooth journey when travelling internationally.
The rules for carrying liquids in hand luggage can vary depending on the country and airport. In the UK, the regulations have recently undergone a change, with some airports scrapping the longstanding 100ml limit for liquids. This change only affects departures from the UK, with arrivals still adhering to the rules of the outbound airport. London City and Teesside airports have already implemented this change, significantly reducing security check times. Heathrow, Gatwick, Stansted, and Manchester airports are expected to follow suit by 2025.
However, countries outside the UK may have their own unique rules regarding liquids. It's crucial to check the regulations of the specific country and airport you're travelling through. Some countries may have more stringent rules than others, and failing to comply can result in delays or even confiscation of items. It's always better to be informed beforehand to avoid any last-minute surprises.
In the United States, for example, the rules on liquids are slightly different. Airports like Atlanta's Hartsfield-Jackson and Chicago's O'Hare have installed new scanners, leading to a slight relaxation of the rules. While travellers are allowed to keep liquids in their bags, the limit remains at 3.4 ounces (100ml) in a single transparent bag. This change is expected to gradually spread nationwide, but it will take time due to the high number of airports in the country.
To ensure a hassle-free journey, it's recommended to check the latest guidelines provided by the relevant country's official sources, such as government websites or airport authorities. These sources will provide the most up-to-date and accurate information regarding liquid restrictions and any other specific requirements they may have. Additionally, checking with your airline can also provide valuable insights, as they are often well-informed about the regulations of the destinations they serve.

Meat, dairy, fish, and animal products are restricted in the UK
There are no explicit restrictions on bringing sweets through airport security in the UK. However, food items may obstruct x-ray images, leading to additional manual checks of your luggage. Liquids are also restricted in hand luggage, and some sweets may be considered liquid products. It is best to check with your airline before travelling.
Regarding meat, dairy, fish, and animal products, there are restrictions in place when bringing these items into the UK. The specific rules depend on the country you are travelling from and the type of product. Currently, meat and dairy products from any EU country are restricted for personal use to prevent the spread of foot-and-mouth disease. There are also restrictions on bringing in meat, dairy, and other animal products from countries outside the EU, Switzerland, Norway, Iceland, Liechtenstein, the Faroe Islands, and Greenland. These rules do not apply to bread, but they do apply to meat or dairy-filled sandwiches.
You cannot bring in meat or dairy products that are not for human consumption, such as pet food made with pig, cow, sheep, goat, or deer meat. However, you can bring up to 2kg of special pet food per person if it is for medical reasons, does not need refrigeration, and is in branded and unopened packaging.
If you are bringing in food or animal products protected by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), you may need to apply for a CITES permit. It is important to properly dispose of any leftover animal products to prevent access by livestock, wild boar, and other animals.
Finally, if you are travelling with goods for business purposes, such as sales samples, professional equipment, or musical instruments, there may be different rules and restrictions. Airport security staff will not allow any items they consider dangerous, even if they are typically permitted in hand luggage. It is always best to check with your airline and review the latest government advice before travelling.

You can bring breast milk through security in a transparent container
While you can bring sweets through airport security, food items can obstruct x-ray machines, so your bag may need to be checked manually by security. To minimise delays, it's recommended that you put sweets in your hold luggage.
Now, regarding breast milk, regulations may vary depending on the country and airport, so it's always a good idea to check with the relevant authorities beforehand. In general, formula, breast milk, toddler drinks, and baby/toddler food are allowed in carry-on baggage. There is no volume limit, and they do not need to fit within a quart-sized bag.
Breast milk and related supplies, such as cooling accessories, are considered medically necessary liquids. You can inform the TSA officer at the beginning of the screening process that you are carrying these items, and they will be screened separately from your other belongings.
To expedite the screening process, it is recommended to transport breast milk in clear, translucent bottles rather than plastic bags or pouches, as these may not be compatible with bottle liquid scanners. If you do not want the breast milk to be X-rayed or opened, you can inform the TSA officer, and additional screening procedures will be followed.
