Current through Register 2024 Notice Reg. No. 28, July 12, 2024
Dry matter of avocados shall be determined by weighing
						the fresh weight and dry weight of a sample of avocados. The testing procedures
						and method of calculating the percent of dry matter shall be as follows:
(a) At the widest circumference of the
					 avocado, remove a core from the entire width of the avocado. Discard the seed
					 portion, and remove the seed coat and skin to the depth of the edible portion
					 from the remaining core pieces. Cut each core piece in half. The core sample
					 shall be removed with a coring device having an inside diameter of 5/8 inch,
					 plus or minus 
					 1/16
					 inch.
(b) Repeat the above for the
					 number of sample fruit required by Section
					 1408.6.
(c) The cored pieces shall be immediately
					 placed in a sealed plastic bag if there is a delay in completing the procedures
					 below.
(d) Weigh a clean petri dish
					 and record the weight (P).
(e)
					 Place all cored pieces on the preweighed petri dish; reweigh the petri dish
					 with the sample and record the weight (F).
(f) Place the petri dish with the sample in a
					 1,000 watt microwave oven and dry the sample at 50% power for 40 minutes,
					 adjusting the power down as necessary to avoid charring the tissue. Remove the
					 sample from the microwave oven and note the weight. Place the sample back in
					 microwave oven for 5 minutes. Remove the sample again and compare weight. If
					 weight is the same, record it as dry weight. Whenever there is a weight
					 difference, repeat this step until there is no weight loss. After the sample
					 reaches a constant weight, record the weight (D).
(g) Calculate the percent of dry matter using
					 the following example:
((D-P)/(F-P)) x 100 = ____________________% dry
						matter
All weighings required by this section shall be recorded
						to the nearest 0.01 gram.
