How to choose moon cake to ensure food safety

The Mid-Autumn Festival is coming, every house cannot live without cakes, cakes.

However, at present there are many types of fake and fake cakes that are not hygienic.So how to choose moon cake to ensure the health of your family?

To prepare a cake, there are many kinds of food materials from flour, fresh meat and meat products, spices and food additives (colorings, preservatives, and anti-oxidants). molds), types of bakery packages. Specially processed by different technologies from manual to industrial chains at the factory or at the household.

Each type of raw material is in danger of contamination of pathogenic microorganisms (molds, yeasts, staphylococcus, cholera, dysentery, typhoid, parasites, etc.), toxic chemical pollution (weight gain, banned antibiotics, preservatives, plant protection chemicals, banned colors, chemicals used as food additives outside the list, toxic chemicals due to expired products, products quality change due to improper storage …). Then the sanitary conditions of the processing place, the processing equipment, the cake storage tool, the hands of the processor and the eaters are at risk of containing the “agents” that cause cake pollution.

Mooncakes do not preserve long (shelf life of only 1-2 months), the Mid-Autumn Festival is very short, the consumer demand of the people to focus increases dramatically when it exceeds the production capacity. ..but because of “profits”, many manufacturers do business in spite of food safety regulations, quality of raw materials for production, and exploitation of goods sources for business.

The ultimate consequence of not ensuring the food safety of a bakery operation or stages is to expose the cake to contamination, which is at risk of acute, chronic food poisoning, foodborne illness and affecting health and life for people to eat.

Therefore, to ensure food safety for the moon cake market, consumers are an important decisive factor. Every consumer should become a “wise consumer”: know how to choose to buy moon cake and use moon cake to ensure food hygiene and safety.

The Milky Way may contain 10 billion Earth-like planets

Through computer simulations and real data, experts estimate the number of planets the size of Earth, which can exist for life.

A team of scientists from Penn State University used data from NASA’s Kepler telescope to calculate the number of Earth-like planets in the Milky Way, Science Alert reported on Aug. 19. Accordingly, 1 out of every 4 stars like the Sun orbits the Earth-like planet, meaning that the Milky Way may contain a total of 10 billion such planets.

This is an important step in the search for extraterrestrial life because creatures will most likely exist in places warm enough to hold liquid water. “Our investment will be more effective if we know where and when to observe,” explained Eric Ford, professor of astrophysics and co-author of the study. The new research helps scientists better plan future space exploration.

The team of experts defined a planet similar to Earth, which is 0.75 to 1.5 times the size of the Earth and orbits the star with an orbit of 237 – 500 days. This is considered a “habitable zone” because the distance from the star is suitable for liquid water to exist on the planet’s surface.

According to Kepler’s observation, 20% – 50% of the stars seen in the night sky have Earth-like planets in the “habitable zone”. However, Ford and his colleagues do not want to estimate the number of Earth-like planets in the Milky Way galaxy based solely on the exoplanets Kepler found. The reason is that Kepler’s search is suitable for the large planet near the host star but not really effective for the small planet far from the host star. Moreover, this telescope also favors small, light-emitting stars of about 1/3 the mass of the Sun.

To estimate the number of planets that Kepler may have missed, the team set up computer simulations based on aggregated data from this telescope and the Gaia spacecraft. They then compared the results with Kepler’s actual data to estimate the number of “eligible” subjects. Depending on the definition, the Milky Way could exist 5 to 10 billion such planets, Ford said.

The next step to finding extraterrestrial life is to study the structure of these planets. “Scientists are particularly interested in finding biomarkers, or signs of life, in the atmosphere of planets the size of Earth,” Ford said.

A planet in a “habitable zone” still needs the atmosphere to be strong enough to help maintain the right temperature for liquid water to exist on the surface. Experts can predict the atmospheric composition of an exoplanet by observing the host star’s light as the planet passes through.
