566	vi	<p>Desiring to bring quality salt to customers as well as preserve the Sa Huynh traditional salt production, Ms. Hong Tham founded SAHU. Having set the first steps many years ago and undergone many ups and downs, the salt brand slowly but steadily made its way to its current position with high-quality salt.</p> <p>The salt from SAHU is harvested and produced according to the traditional method of the Sa Huynh local people. Salt workers process the salt on bare ground instead of cement foundations or plastic covers. It guarantees the environment is not negatively affected and safety for the consumers. Furthermore, this processing allows the salt to absorb the essence of mother earth, generating a natural saltiness with a distinctive flavor and good mineral content. All step are ensured the quality and hygienic standards.</p> <p>Another big plus at SAHU is that they buy salt from the farmers at a higher price than the market. This comes from the brand’s desire to bring local people a better, more stable income and preserve the salt-making profession as well. Therefore, when coming to SAHU, not only are you getting to taste the salt made with earth essence but also contributing to creating a better life for the hard-working salt farmers at Sa Huynh, Quang Ngai.</p>		A	SAHU	SAHU	Châu Me, Phổ Châu, Đức Phổ, Quảng Ngãi, Việt Nam		51	534	21481				tham@sahu.vn	0917010408				none	Y		1664344735	6,4,7		0				N	N	N	1	0	0	0	0				0	4555790	N	N	A	Y	Standard	sahu-en		5.00	2
