Similarly just as there are objective taste receptors for umami and other tastes as a matter of fact, whilst not so obvious, there are inherent physical moral algorithms represent by neuronal system in the brain, e.g. "the ought-not-ness of killing another human"; thus morality is objective.
Justified as below;
That marmite is delicious is objective is a good analogy for moral elements as objective moral facts.Peter Holmes wrote: ↑Tue Dec 13, 2022 8:32 am The is of predication at work
Marmite is delicious.
I/we think Marmite is delicious.
? It's a fact that Marmite is delicious.
? The assertion Marmite is delicious is true.
? The assertion Marmite is disgusting is false.
? The deliciousness of Marmite is objective - a matter of fact - not subjective - a matter of opinion.
In this context, there are no gustatory facts, just as there are no aesthetic and moral facts. It can't be a fact that Marmite is delicious/disgusting, a turd is ugly/beautiful, or capital punishment is morally right/wrong.
The is of predication introduces a subject complement. And that's all.
In this particular case, the deliciousness of Marmite is objective - a matter of fact!
- Marmite is high in umami flavor, as it's fermented with yeast, while oyster sauce is umami-rich, as it's made with boiled oysters or oyster extract, which are high in glutamate.

- Umami or savoriness, is one of the five basic tastes.[1] It has been described as savory and is characteristic of broths and cooked meats.
People taste umami through taste receptors that typically respond to glutamates and nucleotides, which are widely present in meat broths and fermented products. Since umami has its own receptors rather than arising out of a combination of the traditionally recognized taste receptors, scientists now consider umami to be a distinct taste.
In 1985, the term umami was recognized as the scientific term to describe the taste of glutamates and nucleotides at the first Umami International Symposium in Hawaii.[17] Umami represents the taste of the amino acid L-glutamate and 5'-ribonucleotides such as guanosine monophosphate (GMP) and inosine monophosphate (IMP).[14] It can be described as a pleasant "brothy" or "meaty" taste with a long-lasting, mouthwatering and coating sensation over the tongue.

That umami taste receptors detect taste that are savory, i.e. delicious.
Since Marmite is high in umami flavor, marmite will be delicious to all normal humans without damage taste receptors.
This is a fact that can be verified and justified with experiences of all humans which taste marmite.
So it is an objective fact, a matter of fact, a state of affairs that marmite is delicious.
Point there is no question of right or wrong with the deliciousness of marmite, it is just a matter of fact [verifiable] that it is delicious and an innate propensity.
