The Use of Tofu Whey from Food Industry Waste in Podological Care

Abstract

The aim of the study was to create cosmetic formulations used for washing and conditioning based on natural whey derived from tofu. Tofu whey used in the production of hair cosmetics turns out to be valuable waste that replaces water. Whey is an ingredient rich in proteins, oligosaccharides and isoflavones. When trying to follow the principles of sustainable development, we need also to be responsible for protecting water resources. Using whey, we limit water consumption to the necessary minimum. Hence, we also support no water waste trend. Tofu whey, which is a valuable waste that replaces water, was used in the production of podology products. The research was conducted following the approval of the Bioethics Committee, resolution number 223/22. Tests confirming or excluding the properties and performance of tofu whey declared by the Ordering Party were carried out at probands’ homes and in the Dermatology Center (Centrum Dermatologii Sp. z o.o.) in Poznan. The probands were volunteers. A group of 30 people was selected for the study according to the indications for the use of the product submitted for experiments. The selection of probands was carried out after a preliminary assessment of the condition of feet and health. Due to the purpose of the product, the study involved people who declared a desire to improve the appearance and condition of their feet. The study used the imaging method with the participation of a microcamera.
