| Abstract: | In this paper,the vacuum pre-chilling experiments have been employed to investigate the effects of the temperature change inside the vegetable versus time,the different types of vegetable and the pressure in the vacuum container on the process of the vacuum pre-chilling.The water content and the distribution of the water in the vegetable and the construct of the vegetable influence the appearance and the dissipation of the vapor,and so it also influences the pre-chilling temperature and the weigh loss of th... |
