The phrase "naturally preserved" is correct and usable in written English.
It is typically used to describe something that has been kept or maintained in its natural state or condition without any artificial or chemical preservation methods. Example: The fruits were naturally preserved by drying them in the sun, giving them a longer shelf life without the use of preservatives.
Mummy, body embalmed, naturally preserved, or treated for burial with preservatives after the manner of the ancient Egyptians.
Those naturally preserved mummies are believed to have influenced the religious doctrines because they seemed to prove that the individual existed after his death.
Consumer's demand for naturally preserved food products is growing and the utilization of lactic acid bacteria is a promising way to achieve this goal.
-- C. Richard Becker, New York, N.Y. A. The Iceman, a corpse found naturally preserved in an Alpine glacier on Sept. 19, 1991, now lies in a small-windowed freezer in the South Tyrol Museum of Archaeology.
This model enables one to parameterize the stiffness matrix of the finite element (FE) model of the system, such that, in an updating process, properties such as symmetry and sparsity of the original FE model are naturally preserved.
Fermented milks had been made since early times, when warm raw milk from cows, sheep, goats, camels, or horses was naturally preserved by common strains of Streptococcus and Lactobacillus bacteria.
Grazing sheep naturally preserve the landscape by preventing other (less benign) land uses, live an outdoor life and are relatively disease-free.
This technique provides an augmented flow state integrating available observation in the CFD model, naturally preserving a zero-divergence condition for the velocity field.
The small oscillation modes in complex micromagnetic systems around an equilibrium are numerically evaluated in the frequency domain by using a novel formulation, which naturally preserves the main physical properties of the problem.
We thus propose a new approach as well as an algorithm which is second order in space and time with very limited numerical diffusion and allows to accurately describe the advection process and naturally preserves the moment space.
In this paper we introduce link analysis-based techniques to unsupervised activity discovery in video data that naturally preserves the spatiotemporal topology among the video words.
