Drying behavior of a single baking biscuit was modeled using unsteady state, anisotropic, two dimensional, simultaneous heat and mass balances. Solutions of these equations agreed well with the experimentally determined temperature and the moisture d

Mechanical damage to dry kidney beans was assessed using hot and cold water soak-tests at 20 and 80°C, respectively. Damage was revealed as the middle lamella dissolved and the seed coats were released with zero order kinetics. Damage exposed in soa

A bench-top procedure was developed and tested for estimating the acid requirement for modifying the pH of low acid foods. Acid amounts needed to achieve desired equilibrium pH in finished products depended on total solids, protein and ash contents o

Foam characteristics in several commercial beers were evaluated using magnetic resonance imaging, a nondestructive procedure. With this method, foam texture differences and regions of cling, head, and liquid beer can be clearly distinguished. Signifi

In mechanical deaeration of sliced apples, pears and cut green beans, increasing fill temperatures or chamber vacuum enhanced product deaeration, whereas increasing dwell time under vacuum from 3 to 9 sec did not (p < 0.05). Product ability to resist

Seven peach varieties were canned conventionally with added syrup or added water and using high vacuum flame sterilization (HVFS) with and without added syrup. The treatments were assessed for sweetness, sourness, odor intensity, darkness of color, f

Tomato serum (4.25% total solids), which contained all the water-soluble constituents of the tomato but little of the water insoluble fibrous material, was concentrated to 37.17, 42.53, 47.64 and 53.70% levels of total solids. Half of each concentrat
